TfNSW Driver Fatigue Study September 2012
Executive Summary Objective
The overall objective of the research was to provide an up-to-date exploration of knowledge, attitudes
and self-reported behaviours of NSW drivers in relation to fatigue. The study included exploration of:
Awareness and understanding of fatigue;
Attitudes towards fatigue;
Fatigue related behaviours; and
Potential countermeasures for fatigue.
Research Design
The study was undertaken in two separate phases that involved a quantitative survey followed by
qualitative group discussions.
Quantitative Survey:
This phase of research involved an online survey of a representative sample of 1000 NSW licence
holders. The scope of the study was similar to that carried out in 2006, and comparisons to that study
(and another from 2001) have been drawn where relevant.
Qualitative Group Discussions:
The second phase of the study involved a series of eight mini-group discussions with male and female
drivers across Sydney CBD, Parramatta, Newcastle and Wagga Wagga. Each group consisted of between
4 and 6 participants.
Key Findings
Current Driving Behaviour
The majority of drivers (68%) drive their vehicle every day, typically more than three hours a week, with
two thirds of those occasions being for personal reasons.
Within the group discussions, long trips were defined by participants as more than 2-3 hours in duration,
usually to a destination outside of their home city or town. The survey showed that 63% of drivers had
taken three or more long trips (defined as 2 or more hours, outside of their home city/town) in the last
12 months, with the likelihood of taking a long trip higher amongst males 30-49 years (74%).
6
TfNSW Driver Fatigue Study September 2012
As far as breaks were concerned, most drivers did not consider planning or preparing for short trips
(defined in the survey as less than 2 hours in duration, within their home city/town). However there was
some degree of pre-planning for longer trips which mainly consisted of getting the car ready, getting a
good night’s sleep or printing out maps (e.g. from Google maps). Young males were less inclined to
prepare for a long trip, and some indicated they were happy to have a big night out and little sleep
before setting off.
On a typical 2-3 hour trip, most survey respondents reported either stopping only once (55%) or not at
all (31%). Those who had driven longer distances (more than 6 hours) indicated that they had taken a
break on average every 3-4 hours (34%).
The most common places for stopping on long trips were service stations (40%), fast food restaurants
(42%), or places where there were both service stations and restaurants (34%). The most frequently
mentioned motivations for stopping were to use the bathroom (66%), stretch one’s legs (56%), and have
something to eat (53%). One third of drivers (34%) claimed to have stopped due to feeling tired or
drowsy.
Attitudes and Barriers to Stopping When Fatigued
Attitudinal statements provided to survey respondents were grouped into three main categories:
Denial
Agreement with statements such as ‘when tired on a long trip I try to make it to the next town
before I stop’ and ‘when I have to get somewhere by a certain time, I know I can keep driving on
a long trip without stopping’ were particularly strong amongst 17-29 year old respondents (48%
for the earlier statement) and young males aged 17-29 years (37% for the latter statement).
Compromise
Amongst males both 17-29 and 30-49 years there was stronger agreement with statements such
as ‘my driving is not affected by missing a few hours sleep the night before’ (34% and 30%
respectively) and ‘being tired doesn’t change my ability to drive’ (26% amongst 17-29 year old
males).
Compliance
Older drivers (over 50 years) tended to be more compliant and were more likely to agree with
statements such as ‘when I feel really tired on a short trip I would be prepared to pull over’
(85%) and ‘I plan where I will stop for breaks on a long trip’ (72%). Young males aged 17-29 years
on the other hand, tended to agree less strongly with all the compliance statements put to
them.
The perceived seriousness of driving while fatigued has increased significantly over the last 6 years with
63% of drivers scoring driver fatigue an 8, 9 or 10 out of ten in terms of its seriousness in 2006, to 75%
of drivers scoring it 8, 9, or 10 out of ten in this 2012 research. However, while fatigue was seen to be
7
TfNSW Driver Fatigue Study September 2012
important in overall terms, in the group discussions it did not appear to equate with other driving issues
such as speeding or drink driving.
Even so, driving fatigued has increasingly been seen as something that is morally wrong (63%, up from
56% in 2006) and dangerous, with 71% ranking it as most or second most dangerous from a range of
risky driving behaviours. Drivers also agreed that it was important to pull over and rest when feeling
fatigued (85% gave a score between 8 and 10 out of ten in terms of importance).
The reasons for continuing to drive whilst tired tended to be varied. Some of the reasons mentioned in
the group discussions included:
the need to meet deadlines or adhere to commitments;
the belief of becoming more awake in due course;
inexperience with the signs of fatigue;
peer pressure/family pressures;
safety concerns;
anticipation of getting home;
‘beating’ the GPS (i.e. the estimated time set by the GPS);
avoiding frustrations;
a sense of pride;
a feeling of invincibility;
not wanting to waste time;
a feeling that there is nowhere to stop;
not wanting to stop too frequently.
Understanding of Fatigue
Fatigue was recognised as an issue on long trips (but not short trips) and was one that drivers showed a
degree of concern about. However it does not have the same air of seriousness surrounding it as
speeding or driving under the influence of alcohol.
Around a third of respondents had experienced driver fatigue on both long (35%) and short trips (34%),
particularly males aged 30-49 years (48% on long trips and 42% on short trips). However, the frequency
of admitting to driving while fatigued is low (10% ‘very often’ or ‘often’).
The afternoon (12noon-4pm) was a peak time for experiencing driver fatigue on long (33%) and short
(24%) trips, followed by the morning between 9am and 12 noon (13% and 9% respectively). Older
8
TfNSW Driver Fatigue Study September 2012
drivers (aged 50+) tended to experience fatigue more in the afternoon (38%), with younger drivers (aged
17-29) indicating a higher prevalence in the morning (25%) between 9am and 12noon.
The signs of fatigue appear to be well known, however their link to microsleeps was not as well
recognised amongst group participants. The top three recognised early warning signs of driver fatigue
were:
- yawning (45%);
- difficulty focussing (40%); and
- tired or sore eyes (25%).
The warning signs that would cause drivers to stop straight away were:
- a microsleep (86%);
- oversteering (52%); and
- drowsiness (50%).
Knowledge of warning signs and driver fatigue as an issue was mainly seen to have come from previous
advertising with group participants still recalling Dr Karl and his microsleep campaign as well as the
recent ‘Wake up to the signs’ communication campaign.
Over one in ten drivers had been in a fatigue related crash, with this being significantly more likely to
have occurred on a long trip. Those who had experienced a near miss admitted it had shaken them,
however many suggested they would still be willing to drive with someone who they knew to be a little
tired.
Penalties for Driving Fatigued
The group participants noted that fatigue was treated differently to other driving issues (such as
speeding and drink driving), for which ‘the law’ reinforced the importance through rules, regulation, and
enforcement – and this was not seen to be the case with fatigue.
More than half of drivers agreed that there should be a penalty for driving fatigued, with the most
common definition being driving after not having slept for 17 hours or more. However, survey
respondents recognized that this would be hard to police.

Conclusions
From the findings of the research there were a number of issues that emerged for consideration:
1. It became apparent that the notion of a short trip is an ambiguous one. In any future research or
communication, caution will need to be taken when using the term ‘short trip’. It will need to be
defined clearly as to what is meant by the term in a way that is not open to misinterpretation.
2. In addition, ‘short trips’ are currently not regarded as requiring a break of any kind. Any future
communication should give consideration to alerting drivers to the danger of fatigue in any
situation by suggesting that it is not only an issue on long trips, but also on short trips.
3. There appeared to be little pre-planning in terms of formalised selection of stops or breaks along
the way in the case of long trips. In that regard, there may be merit in devising a strategy aimed at
encouraging drivers to pre-plan regular rests or breaks within their trip.
4. Less severe symptoms of fatigue were ignored and many did not know when being tired was too
tired. That is, when the chance of a microsleep is high. In that regard, there is an opportunity to
communicate the ease with which a microsleep can occur when tired and strongly link other signs
of fatigue with the onset of microsleeps.
5. The 17-29 year male segment were generally of the mindset that they are somewhat invincible and
capable of “pushing on”, even when they do experience signs of fatigue. They were also less
inclined to prepare themselves before taking a long trip. While the need to ‘push on’ was strongest
amongst this younger sub-group, consideration should be given to further educating drivers on
the signs of driver fatigue in order to heighten the perceived level of risk associated with
experiencing ‘early warning’ signs. This could also stress the importance of stopping immediately
when those signs appear, no matter how long the trip; to not push on, especially when close to
reaching their destination.
6. The peer pressure to demonstrate that you can keep driving when tired was strong amongst younger males. Perhaps the force of peer pressure can be harnessed to stop drivers from pushing on by devising a strategy that is specifically targeted at young male drivers who are too proud to take a break.
7. When compared with driving under the influence of alcohol and to some extent speeding, driving
fatigued was not considered as serious. We would suggest consideration be given to using future
communication to lift the seriousness and prevalence of driver related fatigue crashes and
perhaps utilising comparisons of driving fatigued to driving with a high blood alcohol level or at
high speeds.
8. Of the campaigns, the Dr Karl campaign was the most well recalled, with the most prominent
residual messaging being the discussion about microsleeps and the night time setting. There was
also a perception that the risk of a microsleep is much greater in the evening (which appeared to
have been fuelled by advertising featuring Dr Karl’s reference to circadian rhythms), so much so that
10
TfNSW Driver Fatigue Study September 2012
many drivers try to time their arrival time to be before dusk. However, many drivers were also
experiencing fatigue when driving in the afternoon. In future communication, it may be beneficial
to highlight the dangers of fatigue during the afternoon as drivers believed they were more
cautious at night and associated microsleeps more with night time driving.

TfNSW Driver Fatigue Study September 2012
Introduction
This project was commissioned by the Centre for Road Safety in order to get an up to date read on the
level of understanding and knowledge, as well as attitudes and self-reported behaviours of NSW drivers
in relation to driver fatigue.
The research was conducted between May and June 2012.
Background
Driver fatigue is known to be a major contribution to the NSW road toll. In 2011 around 70 people were
killed on NSW roads due to crashes where fatigue was identified as a factor. Fatigue itself is a general
term that has been commonly used to describe the experience of being ‘sleepy’, ‘tired’ or ‘exhausted’. It
is conceptualised as both a physiological and a psychological experience. Known early warning signs of
driver fatigue include:
Yawning
Poor concentration
Tired eyes
Restlessness
Drowsiness
Slow reactions
Boredom
Oversteering
A person with fatigue may also fall asleep while driving. These microsleep episodes may last for a
fraction of a second or up to thirty seconds, and it is not unusual for the person experiencing it to be
unaware that they were in fact asleep.
Although driver fatigue can occur in any driver, the majority of drivers involved in fatigue related crashes
in NSW were males, particularly those aged 17-49 years. In fact, in 2010 74% of all fatigue related
crashes were males of this age group.
Prior research has also shown that there are a number of clear risk factors that increase the propensity
for driver fatigue, and include:
Sleep loss/sleep deprivation
Long hours of wakefulness
Driving during normal sleeping hours (disrupting circadian rhythms)
12
TfNSW Driver Fatigue Study September 2012
Sleep disorders
Time spent driving without rest
Alcohol consumption
Driver fatigue has also been found to be a complex and difficult road safety issue to address. Unlike
other major driving related issues (such as drink driving and speeding), there is currently no legislation
or enforcement in NSW to specifically regulate driver fatigue (except for heavy vehicle drivers).
Quantitative surveys to understand the knowledge, attitudes and behaviours of NSW drivers in relation
to fatigue were undertaken in both 2001 and 2006 by the Centre for Road Safety (previously part of the
Roads and Traffic Authority). Efforts have been made to increase public awareness of the issue of
fatigue through public education campaigns that developed as a result of those studies. Transport for
NSW’s (TfNSW) current public education strategy for fatigue focuses on educating drivers about the
physiological and psychological symptoms of fatigue. The current campaign ‘Wake up to the signs’
outlines the symptoms and instructions for addressing driver fatigue - tired eyes, drowsiness, yawning,
and loss of concentration, and to take a break.
Given that a new driver fatigue strategy, including a new marketing campaign, is planned for
development to specifically address driver fatigue in NSW, it was felt that updated research was
required to help guide and inform this process.
This document provides the findings of the study undertaken by Woolcott Research in May and June
2012.

Objectives
The overall objective of the research was to provide an up-to-date exploration of knowledge, attitudes
and self-reported behaviours of NSW drivers in relation to driver fatigue. The study included an
exploration of:
Awareness and Understanding of Fatigue
• Knowledge of sleep related causes of fatigue (including sleep debt);
• The understanding of how these causes can influence and impact driving performance;
• Awareness of the symptoms of driver fatigue;
• The level of each symptom deemed necessary to prompt action.
Attitudes Toward Driver Fatigue
• Current attitudes toward being tired when driving including the degree of social acceptability,
negative effects on driving, perceived dangers etc.;
• Where driver fatigue is seen to ‘fit’ in relation to other dangerous driving behaviour, e.g.
speeding, drink driving etc.;
• The behavioural motivators/drivers that result in people deciding to drive while tired, and how
these can be addressed;
• Known motivators such as “meeting deadlines” and “pushing on to get there” and what is
required to alter the perceived need to continue on.
Fatigue Related Behaviours
• Motivators for taking breaks and the specifics of these (e.g. how frequently and for how long),
and whether they were prompted by any specific driver fatigue symptoms;
• Experiences of near misses;
• Action commonly taken to avoid or combat driver fatigue, both prior to and during the trip;
• The impact of passengers on fatigue-related behaviours;
• Barriers to the adoption of good fatigue management practices and how these can be overcome.
14
TfNSW Driver Fatigue Study September 2012
Potential Countermeasures for Fatigue
• Potential motivators and strategies that may lead to a positive attitude shift and/or behavioural
change to ultimately reduce incidences of driver fatigue;
• The acceptance of Government implemented measures to counter the issue of fatigue, and
generate ideas in terms of what additional measures could be taken;
• The potential introduction of legislation prohibiting driving whilst fatigued, as well as various
potential penalties for the offence.
15
TfNSW Driver Fatigue Study September 2012
Methodology
The study was undertaken in two separate phases that involved a quantitative survey followed by
qualitative group discussions.
Quantitative Survey:
The first phase of research involved an online survey of a representative sample of 1000 NSW licence
holders. Within the report we have analysed the results by the main groupings of age, gender and
location. Throughout the report ‘metro’ refers to licence holders within the Sydney Metropolitan area
and ‘regional’ to licence holders from the rest of NSW.
Survey respondents were able to indicate that they were holders of multiple license types, and
as such the total adds to more than 100%.
To provide the contact sample, the services of an external panel provider (Research Now) were utilised.
In turn, the survey respondents (referred to as ‘respondents’ throughout the report) were provided with
a small incentive once the survey was complete and validated. This incentive is credited to the account
of the respondent – who, when they reach a minimum dollar amount, is able to redeem vouchers from a
range of (mainly online) outlets and service providers.
While a panel provider was used to provide the sample, Woolcott Research maintained responsibility for
scripting and hosting the questionnaire. This allowed us to include our normal quality control
procedures in the checking of set-up, and monitoring progress on a daily basis.
The average duration for questionnaire completion was just under 23 minutes, and the fieldwork was
carried out between 9 and 22 May 2012.
The scope of the study was similar to that carried out in 2006, and comparisons to that study, and
another from 2001, have been drawn where relevant. Both previous studies used a CATI methodology,
with a sample of 1075 NSW drivers in the 2001 study and a sample of 1000 NSW drivers in 2006.

Qualitative Group Discussions:
The second phase of the study involved a series of eight mini-group discussions, as per the table below,
consisting of between 4 and 6 participants in each:

Females 17-25 years
‘Singles/Couples’ 30-50 years
‘Families’ - 2 groups
TOTAL 4 groups 2 groups 2 groups 8 groups
A screening questionnaire was used to ensure that all group members (referred to as ‘participants’
throughout the report) had:
Taken more than one ‘long trip’ in the last 6 months (of 2 hours or more);
Driven more than twice a week for personal reasons; and
Felt a sense of fatigue while driving in the last 6 months.
The mini-groups were conducted in locations central to the participants, with viewing facilities made
available for all Sydney groups. The sessions ran for up to an hour and a half, and participants were
offered a cash incentive to compensate for their time and thank them for their cooperation. The
participants were recruited using professional group recruiters who identified people from their data
base that fit the criteria and then asked if they could attend a group discussion.
Pre-Group Task:
To encourage group participants to be open and honest in their discussion of fatigue a short ‘homework’
exercise was given to each group participant to complete (see Appendix 2). This asked details of their
last long distance trip, including who they were travelling with, the original and destination locations,
how many stops were taken, the purpose of stops taken, length of time for stops taken, how they felt at
various points along the way etc. This ensured that participants had pre-established trip details, and
were not tempted to provide more socially acceptable details of their driving behaviour in the group
discussions.

1. Driving Behaviour
1.1. Frequency of Driving
The majority of respondents drove frequently, with more than two thirds (68%) driving daily, and a
quarter (25%) driving a few times a week. Only 7% of the respondents drove less often (Figure 1).
Further details of the main sub groups of interest are available (for all measures) in Appendix 1, and in
this case they show that younger respondents, aged 17 to 29 years, were the least likely to drive on a
daily basis (60% for the males and 61% for the females, see Table A1), while regional respondents were
more likely than the metropolitan respondents to be daily drivers (73% and 66% respectively).

As indicated in Figure 2, the frequency of driving is reinforced by the amount of time that respondents
indicated they spent driving (on average) in a typical week – with half (50%) driving between three and
ten hours, and more than one in five (22%) driving between eleven and twenty hours.
Generally, female drivers were less frequent drivers than males – with 25% of females aged 17 to 29
years, 29% of females aged 30 to 49, and 27% of females aged 50 or over driving less than three hours a
week - compared to 20%, 17%, and 17% of males respectively (see Table A2).

1.2. Personal vs. Work Driving
In total, 71% of driving was attributed to personal purposes, with the remainder (29%) classified as work
related travel (Figure 3).
The proportion of work related travel was significantly higher amongst those who drove on a daily basis
(36%), and significantly lower for those who drove less often. There was also a positive correlation
between the proportion of work driving and the hours per week spent behind the wheel, with 62% of
those driving for 20 hours or more a week being for work, compared to only 19% of those who drove
under three hours a week.
Males aged 30 to 49 years had the highest proportion of work related travel (41%), with heavy vehicle
drivers being close behind (39% of their driving was for work). Females aged 50 or over undertook the
lowest proportion of work travel (22%, see Table A3).

travel only.
1.3. Driving at Night
Figure 4 shows that the majority of respondents (67%) did very little or no driving between the hours of
10pm and 6am. The incidence of this has decreased significantly since the 2006 study (then 74%). Those
spending the least amount of time (under 10%) driving between 10pm and 6am were females aged 50
or over (79%), females aged 30 to 49 (77%), drivers in regional areas (77%), and males aged 50 or over
(76%, see Table A4). Spending less than 10% of time driving between 10pm and 6am was significantly
20
TfNSW Driver Fatigue Study September 2012
lower amongst males aged 17 to 29 (33%). Spending more than 10% of time driving between 10am and
6pm increased significantly from 2006 (see Figure 5).

It follows that males were significantly more likely to indicate that a higher proportion of their driving
was done at night, with two fifths (40%) of males aged 17 to 29 indicating that more than 20% of their

While night driving was not a specific area of exploration for the group discussions, it was referenced by
participants in relation to fatigue. Those who found themselves driving at night felt that they always
drove more cautiously and with greater concentration specifically because they felt there was greater
danger involved with night driving generally. As such they suggested that they were aware of the need
to be fully alert when driving at night and so took extra precautions when they had to do so.
Participants stated that the onset of a microsleep was more strongly associated with night time driving
than driving during the day - which then meant that any signs of fatigue were more likely to be
dismissed in the daytime.
“Maybe it’s because you know you’re meant to be sleeping at night, so you’re just more aware of
how you’re feeling, and you’ll do something about it” – Female, Family, Newcastle.
1.4. Short Trip Driving Behaviour
The incidence of having taken a short trip (defined in the survey as a trip less than 2 hours duration
within their home city/town) in the week prior to the survey was extremely high – with 95% of all
respondents indicating that they had taken at least one in that time period. Just over one in five (21%)
had taken one or two such trips, and more than half (51%) had taken three to ten within the week prior
to the study. Almost one quarter of all respondents (23%) had taken more than ten short trips within
the week (Figure 6).
Males aged 17 to 29 were the least likely to indicate that they hadn’t taken a short trip (8%) and the
most likely to have undertaken three to ten short trips (59%, see Table A5). Females aged 17 to 29 and
those aged 50 or over were more likely to have taken just one or two short trips (26% for each).

Base: All survey respondents (n=1002). Q3a In the last week, how many times did you drive on a short trip (less than 2 hours, within
your home city/town?)
It emerged from the group discussions that a ‘trip’ was seen to be a drive taken for a special occasion,
not day-to-day driving undertaken for things like a visit to the local shops or commuting to work. This
22
TfNSW Driver Fatigue Study September 2012
suggests that the survey results shown above (Figure 6) may well underestimate the true extent of short
trip taking.
“A trip isn’t your regular drive. A trip is something you do with friends or family for pleasure” -
Male, Empty Nester, Wagga Wagga
“A trip to me is something I’d look forward to. I wouldn’t even think of my usual driving around
town in that way” – Male, Retiree, Sydney CBD
It followed that a short trip was thought of as something that was easily ‘doable’, generally requiring no
planning or preparation. The destination for a short trip was generally likely to already be known to the
driver, and so no real route planning was involved either.
“You just get in the car and go really” - Male, Single/Couple, Wagga Wagga
To this end many participants also felt that a short trip would be handled by a single driver, and without
the need for a formal stop for food or even a toilet break.
As shown in Figure 7, the vast majority of short trips were in fact undertaken without any stops. Even so,
almost one in five respondents (17%) had made at least one stop on their last short trip. While not
supported by the group discussions, male respondents aged 17 to 29 were the most likely to have
indicated that they took a break while on their last short trip (43%, see Table A6).

While the survey respondents were provided with a definition of a short trip (less than two hours, within
their home city/town), there was somewhat less agreement on the duration of a short trip amongst the
focus group participants. While a few participants referenced trips of half an hour or more, most tended
to think that a short trip was around one hour, and continued on to around three hours.
“To me it’s anything that I can do in one go without much hassle” – Male, Single, Sydney CBD

TfNSW Driver Fatigue Study September 2012
1.5. Long Trip Driving Behaviour
The survey respondents were provided with a definition of a long trip (more than 2 hours, outside their
home city/town), while in the mini-groups this aspect was open for discussion. There was considerably
more agreement amongst the participants of what a long trip was, compared to the relatively diverse
opinions that were expressed in relation to short trips. To most participants a long trip involved a degree
of preparation, and generally involved the need for a stop or rest along the way.
“A long trip isn’t as easy to do in one stint. You need to be prepared for them…. Well, depending
on how long they are really” – Male, Single/Couple, Wagga Wagga
In terms of duration, there was agreement in the mini-groups that a long trip continued on where a
short trip left off – that is, generally three hours or more.
“Well if a short trip is up to three hours I guess a long one is anything more than that” – Female,
Family, Newcastle
All survey respondents had undertaken at least one long trip (for personal reasons) within the past 12
months. While the overall distribution of trips made was similar to that measured in 2006 (see Figure 8),
the respondent base for 2012 on the whole reported a significantly greater number of long trips taken.
In fact, almost half of all respondents in 2012 (49%) indicated that they had taken three to ten long trips
within a 12 month period – compared to 37% in the 2006 study.

Males aged 30 to 49 had the highest incidence of taking between three and ten long trips in the 12
months prior to the 2012 study (58%, Figure 9). Males aged 50 or over, and respondents in regional
areas were the most likely to have undertaken more than ten long trips (18% and 20% respectively – see

Break Locations
When choosing from a list of location types for taking breaks while on long trips, practical reasons
featured highly (Figure 10), with food and petrol accounting for a relatively large proportion of
responses - 42% had stopped specifically for food at a fast food or family restaurant; 40% stopped
specifically for petrol; and 34% for both food and petrol.
While not featuring at the top of the list, stops made specifically at rest locations were also mentioned –
with 23% stopping in a rest area, and 8% at a Driver Reviver site.
Regional drivers were less likely to stop at a fast food or family restaurant (35%, compared to 44% of
metropolitan based drivers), though they were significantly more likely to have used a rest area (30%,
compared to 20% of metropolitan drivers – see Table A9).
Figure 10: Common Break Locations - Most Recent Long Trip (Prompted)
Base: All survey respondents (n=1002). Q4f On that long trip, which of the following places did you stop to take a break? (Prompted)
Reasons for Breaks
When asked why they stopped, the most common reason chosen by respondents from a list was the
need for a toilet break (66%, Figure 11), particularly for females (75% amongst respondents aged 50 or
over and 73% amongst those aged 30 to 49). Hunger and petrol were also toward the top of the list
mentioned by 53% and 41% of all respondents respectively.
A break from driving was a relatively common reason for stopping with many mentioning ‘the need to
stretch legs’ (56%), as well as ‘taking a break from staring at the road’ (36%), due to feeling ‘tired or
drowsy’ (34%), ‘starting to lose concentration’ (22%), ‘seeing a rest area’ (17%), and seeing a ‘Stop.
26
TfNSW Driver Fatigue Study September 2012
Revive. Survive’ sign (13%). Males aged 30 to 49 were the most likely to mention these reasons for their
stops (see Table A10).

Base: All survey respondents (n=1002). Q5 Thinking about driving on a long trip, what prompts you to take a break? (Prompted)
Indeed, the main reasons for stopping mentioned in the mini groups were generally similar to the survey
results, with participants indicating that they primarily stopped for:
Food;
A toilet break;
To get petrol;
To swap drivers; or
If they were getting tired.
Their reasons were most likely to be what they saw as the practical ‘necessities’ (food, toilet and petrol)
as opposed to any real desire to remain fresh and awake while driving. In some of the discussions
aspects such as wanting to swap drivers only appeared after more probing on the issue had taken place.
Even so, some of the younger participants did indicate that they would also stop if/when they felt the
need to do so due to tiredness, restlessness and boredom.

Trip Planning
While there were frequent suggestions in the mini-groups that a long trip required some forethought
and trip preparation, this preparation did not tend to involve formalised route selection and pre-
planning of potential stops or breaks along the way. Instead, planning tended to involve:
Checking the condition of the car
With the exception of the young females, many participants indicated that they would make
sure that their car was capable of the trip before setting out. This would generally involve at a
minimum making sure that the petrol tank was full, but for many it also involved checking the
oil and water in the car, as well as checking the tyre pressure.
“Some things, like checking the tyre pressure, are just routine to me. Safety is an important
aspect in taking a trip of any real distance” – Male, Retiree, Sydney CBD
Planning when to leave
This aspect was seen to differ by both age and gender. The younger male participants indicated
that they were likely to set off when they woke up - which could be mid to late morning, whilst
the older participants tended to suggest that they specifically planned when they wanted to
leave – either to ‘beat’ the peak hour traffic getting out of the city, or to coincide with their
desired arrival time at their destination.
“You certainly need to know what the best time is to leave Sydney, or you end up adding extra
time being stuck in traffic” – Male, Family, Parramatta
Getting rest before the trip
While not something undertaken by all, those in the mid to older age groups indicated that they
were quite aware of the need to be well rested prior to a long trip, and as such they took steps
to ensure that they had a good sleep prior to their planned departure (which would generally
happen in the morning).
“You need a good sleep to be able to go the distance” – Female, Family, Newcastle
Not drinking the night before departure
Along similar lines to the idea of getting a good nights sleep, some participants refrained from
drinking alcohol the night before they took a trip. While this certainly did include some of the
younger female participants, it too appeared to be more prevalent amongst those in the mid to
older age groups.

“Even if you’re under the limit, you can still feel crook if you’ve had a few drinks, and you don’t
want that if you’re gunna be driving for a while” - Female, Single/Couple, Parramatta
Eating well beforehand
Some of the older participants also felt it was important to plan a good meal before departing
on a long driving trip. Not only did this prepare them for the driving task, but it was also seen to
minimise the need to stop soon after departing.
“Nothing worse than having to stop soon after setting off so that you can get your breakfast. It
just puts you behind” – Male, Empty Nester, Wagga Wagga
Ensuring that children will be kept entertained
Those with children indicated that it was important for them to prepare some sort of
entertainment for their children to keep them amused throughout the journey – including
DVDs, music, puzzles and games.
“If you’re well prepared you can cut out some of the ‘are we there yets?’” – Male, Family, Sydney
CBD
Purchasing snacks and drinks for the trip
Almost all participants indicated that they prepared some sort of food and/or drink for their
long car trips. For the families and older participants this included soft drinks and water as well
as lollies and sometimes sandwiches.
“You always need lollies on hand, but I will also pack a few drinks and the odd sandwich if it’s a
decent trip” – Female, Family, Newcastle
Consuming caffeine
The younger participants (of both genders) were also likely to mention sugary snacks, but their
preparation was more likely to involve the inclusion of energy drinks or other known caffeine
sources that they felt would assist with reducing fatigue.
“I’d have a Red Bull before I left, and then take another one or two with me” – Female,
Single/Couple, Parramatta
Undertaking basic route investigations
With the exception of the older drivers, few were going to the extent of pre-planning stops,
though quite a few did rudimentary trip planning by determining the overall trip time and
distance involved.
29
TfNSW Driver Fatigue Study September 2012
“You need to at least know how long it will take you to get from A to B” - Male, Single/Couple,
Newcastle.
While the incidence of pre-planning breaks/stops appeared to be minimal amongst the mini group
participants, some, particularly in the older groups, did take the time prior to departing to think about
and plan where they would stop.
These older (and more experienced) drivers were more likely to have favourite stop locations, and may
actually plan their trip around such locations in order to make the trip an enjoyable part of their overall
outing.
“If I’m going down South, I always stop at the pie shop in Robertson” – Male, Family, Parramatta
“You get to know where’s worth stopping, and where to avoid” – Male, Retiree, Sydney CBD
Some also planned their stops around meal times, and so calculated likely stops based on their
departure time.
“If you’re going to stop for morning tea and then lunch you get to break the trip up, and you’ll
know approximately where you’re meant to be at those times of day, so you know before you
leave where you’re likely to stop” – Male, Family, Parramatta
A few also went to the trouble of printing out their trip route and had also pre-selected potential places
to stop. This was more likely to occur when they didn’t know the destination very well, and so didn’t
know what their options would be in terms of where to stop.
“When we drove to Bendigo a few months back I checked out the route and printed off a few
suggestions of places to stay along the way” – Male, Empty Nester, Wagga Wagga
In comparison, the younger participants (particularly males) were considerably less likely to undertake
any such planning. Instead, they were likely to make their decisions when on the move, and this mindset
tended to have a basis on a desire for them to lead a relaxed and spontaneous lifestyle. They expressed
a desire for things to be unplanned – suggesting that trips of this nature tended to add to the overall
sense of adventure.
“I like to play it by ear” – Male, Single, Sydney CBD
“I just get going when I wake up and feel like it”- Male, Single, Sydney CBD
As such, given that stops were unlikely to be pre-planned amongst this age group, they were unlikely to
stop until they felt the need to do so for a specific reason - be that for food, petrol, or a toilet break.
“You just stop when you’re hungry. When you’re near a Maccas” – Male, Single, Sydney CBD

Planning to Avoid Fatigue
When asked what drivers had done before a journey to avoid driving fatigued, the vast majority of
respondents said unprompted that they had ensured that they ‘had a good night’s sleep’ (72%, Figure
12).
Other avoidance tactics mentioned less frequently were ‘having a decent meal’ (18%) and ‘drinking
coffee/energy drinks’ (16%). A minority of drivers also spoke of ‘planning the trip’ (9%), ‘drinking plenty
of water’ (7%) and ‘making sure they had music’ (5%) as preparation strategies to avoid fatigue.
Males aged 17-29 years were less likely to prepare themselves by ‘having a good night’s sleep’ (57%)
than the other age groups, however were more likely to rely on ‘drinking coffee/energy drinks’ before
setting off (20%) as were the 17-29 year old females (30%, see Table A29).

Limiting the Impact of Fatigue
Respondents were also asked to indicate what types of things they had done during their trips to avoid
driver fatigue. The most frequently mentioned strategy by over half of the drivers surveyed was having
a ‘break/stop/rest’ (51%, up from 43% in the 2006 study, Figure 13).
The next most common tactic to help avoid driver fatigue during the journey was ‘listening to the radio
or music’ (25%, down slightly from 29% in the 2006 study), followed by ‘talking to other passengers’
31

(17%, compared to 16% in the 2006 study), then ‘drinking coffee/caffeine’ (13%, compared to 20% in
2006).
During the journey there was a marked difference in the tactics being employed by drivers to combat
fatigue. Older male drivers over 50 years were more likely to ‘break/stop/rest’ (69%), whilst younger
females 17-29 years were more likely to ‘listen to the radio’ (46%) or ‘talk to other passengers’ (26%, see
Table A29).

2. Attitudes Toward Driver Fatigue
2.1. Perceptions of Driving When Fatigued
The majority of group participants appeared to have a good grasp of the term ‘fatigue’ and what it
meant. While most participants also indicated that they were relatively familiar with the term ‘driver
fatigue’, they suggested that it wasn’t necessarily something that had worked its way into everyday
speech. They indicated that the more commonly used term was simply ‘feeling tired’, which ultimately
was felt to have the same meaning as ‘fatigued’.
“You don’t go around saying, I feel fatigued” – Male, Single, Sydney CBD
Nonetheless the concept of driver fatigue was well known as a potential danger to drivers. All
participants indicated that they were aware of at least some of the main signs of driver fatigue – though
they clearly only associated the term with long trips (as opposed to short trips).
In the survey, perceptions of driving when fatigue were assessed through a relatively large battery of
attitudinal statements, which were grouped in the analysis process into three mind-sets - namely Denial,
Compliance and Compromise. The Denial factors were those more at the extreme end of negative
attitudes toward driver fatigue and avoidance behaviours, the Compliance factors were the statements
displaying positive attitudes and behaviour toward driver fatigue, and the Compromise factors were the
mid ranging attitudinal statements that were not at either the extreme negative or positive end of the
attitudinal spectrum.
In terms of Denial Factors, there was strongest agreement overall with the attitudinal statement ‘if
other people are in the car I’m more likely to stop’, with 63% agreeing (strongly 25% combined with
slightly 38%) with this statement (Figure 14). Around two fifths of all respondents also agreed that
‘when tired on a long trip I try to make it to the next town before stopping’ and ‘if I’m within an hour of
home and I feel tired, I won’t take a break and will just push on to get there’ (40% and 38%
respectively).
Around a quarter of all respondents also agreed that ‘when I have to get somewhere by a certain time, I
know I can keep driving on a long trip without stopping’, ‘I wouldn’t consider stopping on a short trip,
even if I felt tired’, and ‘I get frustrated driving on a long trip if I have to stop before I really need to’.
With the exception of the statement ‘if other people are in the car I’m more likely to stop’, young males
aged 17-29 years were more likely to agree with each of the Denial factor statements, while males aged
50 or over were less likely to agree with them (Table A11). So too, the young female respondents (aged
17-29 years) were also more likely to agree with the Denial statements, while the females aged 50 or
over were less likely to agree.
Metropolitan respondents were also more likely than the regional respondents to agree with each of
the Denial statements.

TfNSW Driver Fatigue Study September 2012
The Compliance factor statements gained the greatest agreement overall amongst respondents,
however the statements with comparatively lower agreement were those that referred to regularly
using rest areas to take breaks and planning where to stop for breaks on long trips.
Perhaps not surprisingly, the majority (93%) agreed (strongly or slightly) that they are responsible
drivers, and a similar proportion agreed that it is dangerous to ignore the early warning signs of driver
fatigue (90% agreed strongly or slightly, Figure 15).
Younger males (aged 17-29 years) had the lowest level of agreement on all of the Compliance
statements. In particular, younger males did not agree as readily that ‘it is dangerous for the average
driver to ignore the early warning signs of driver fatigue’ (67%, versus 90% for the total) or that ‘its
dangerous for them to ignore the early warning signs’ (66%, versus 88% for the total), or that they
‘would be prepared to miss out on something they like in order to get a good night’s sleep’ (55%, versus
74% for the total, see Table A11).
With the exception of the statement ‘it is dangerous for me to ignore the early warning signs of driver
fatigue’, the young female respondents (aged 17-29 years) were less likely to agree with any of the
Compliance statements, while the females aged 50 or over were more likely to do so for each of these
statements.

TfNSW Driver Fatigue Study September 2012
There was relatively low agreement with most of the attitudinal statements where Compromise was
evident. While 37% agreed that they ‘experience driver fatigue on short trips as well as long trips’, the
remaining statements obtained considerably lower agreement (22% or less agreed strongly or slightly).
The highest level of disagreement was recorded for statements such as ‘driving when I am tired is not
really dangerous’; ‘being tired doesn’t change my ability to drive’; and ‘I don’t believe I will crash if I
drive when I am tired’ (Figure 16).
Older males (aged 50 or over) were less likely to agree that they ‘experience driver fatigue on short trips
as well as long trips’ (28% versus the average of 37%). Both male and female young drivers (aged 17-
29), were more likely to agree that their ‘driving is not affected by missing a few hours’ sleep the night
before’; and that they’d ‘prefer to keep going even if they were tired than stop for a break’. ‘Family’
males (aged 30-49 years) more often agreed that they’d ‘rather have a coffee/energy drink than stop
for a break’ (26%); and younger males more often agreed that ‘being tired doesn’t change my ability to

In looking at the differences over time it should be noted that in 2001 only drivers who indicated they
had experienced fatigue on a long trip were asked to respond to these statements, which may account
for the higher overall agreement levels for that year (see Figure 17).
Even so, significant differences in agreement were apparent between 2006 and 2012. Positively, there
was a significant increase in the proportion of respondents who agreed that they would be prepared to
pull over on a short trip if they felt tired (up from 67% in 2006 to 76% in 2012). Another positive
outcome was the significant decrease in the proportion who agreed that they would continue driving
when fatigued if they were only an hour from home (down from 43% in 2006 to 38% in 2012).
However, there was also a significant increase in the proportion of respondents who agreed that they
would try and stop as few times as possible (up from 27% in 2006 to 33% in 2012).

The Seriousness of Driver Fatigue
In terms of the perceived seriousness of driver fatigue as an issue, Figure 18, shows the percentage of
respondents who rated each driving factor as extremely serious, i.e. a 9 or 10 out of 10 in terms of its
seriousness in causing death and serious injury on NSW roads. Drink driving was rated most frequently
as extremely serious (86%), followed by driver fatigue (75%) and speeding (73%). Not wearing a seatbelt
was not rated as serious as the other factors assessed (67%). Comparing the results against previous
studies, driver fatigue has continued to increase significantly in each study, in terms of its perceived
seriousness.
The younger males (aged 17-29 years) consistently rated all of these factors lower in terms of perceived
seriousness, than their older and female counterparts (see Table A12). Driver fatigue, speeding and not
wearing a seatbelt, were felt to be equally serious amongst this young male sub-group (45%, 42% and
43% respectively).

Similarly, when asked to indicate which behaviours they considered to be morally wrong, driving with an illegal blood alcohol level was selected most often (86%), followed by using a hand held mobile (67%) then driving after being awake for 17 hours (63%). The perception that driving after being awake for 17 hours is morally wrong has increased gradually over time (by 9 percentage points over 11 years).
The proportion that suggested that drink driving is morally wrong fell significantly from 97% to 86% over the past six year period (Figure 19). However, the definition used in both previous studies was ‘driving with a blood alcohol level of 0.06’ which may have been a factor in the reduction.
38
TfNSW Driver Fatigue Study September 2012
Driving after being awake for 17 hours was less likely to be considered ‘morally wrong’ by young females aged 17-29 years (49% versus 63% for the total). Using a hand held mobile phone was also felt to be morally wrong more often than driving after being awake for 17 hours amongst this sub-group (59%, versus 49%, see Table A13).

In being asked to rank different driving behaviours in terms of how dangerous they were seen to be, half
the sample ranked driving with an illegal blood alcohol level as the most dangerous of the behaviours
evaluated. Driving after being awake for 17 hours was ranked as the most dangerous by just over one
third of respondents (36%, see Figure 20).
There were no significant differences amongst the sub-groups on this issue, with the exception that
younger drivers (both males and females) were less likely to indicate that talking on the phone while
driving was the most dangerous behaviour (see Table A14).

Base: All survey respondents (n=1002). Q7b. Please indicate how dangerous you find each of the following driving behaviours by
ranking them from 1 to 4 – where 1 is the most dangerous, and 4 is the least dangerous of the behaviours presented.
When exploring perceptions of driver fatigue in the group discussions, most participants initially claimed
that fatigue was a major issue, and one that was of some concern to them. In fact, many claimed that
driver fatigue was just as important as other driving related issues such as speeding and drink-driving.
However, on further exploration of the issue, and after much further probing, it became evident that
while fatigue may be seen to be important in overall terms, it did not necessarily equate with other
driving issues.
“If someone was tired I would still let them drive and I’d keep a close eye on them, but I wouldn’t
get into a car with someone who had been drinking and keep a close eye on them” – Male,
Single/Couple, Wagga Wagga
One of the most common explanations for the difference in perception between fatigue and other
driving issues, was seen to be due to the way ‘the law’ treats these issues. Participants indicated that
the importance of other driving issues was reinforced through rules, regulation, and enforcement – and
this was not seen to be the case with fatigue.
“You lose points and you lose money if you speed. They can’t really do anything about you being
tired” – Female, Single/Couple, Parramatta
Another reason for the difference was the perception that fatigue is not as commonly mentioned in the
media. Participants felt that major crashes/incidents were often reported in the press, and while they

TfNSW Driver Fatigue Study September 2012
felt that there must be incidences where fatigue was referenced, they had stronger recall of reports of
speed and alcohol related crashes and fatalities.
“I don’t know. I’m trying to think of something I’ve seen that was specifically about fatigue. I can
picture crashes with cars wrapped around poles due to speeding, and people getting caught with
ridiculously high alcohol levels, but I can’t remember anything that was showing a crash caused
by fatigue” – Female, Family, Newcastle
There was also a feeling expressed that there were a significant number of roadside reminders (such as
wreaths/crosses, and skid marks leading off the road) that they tended to attribute to speed. While
some reasoned that some of these incidents may have been a result of fatigue, they were more likely to
automatically think of speed when they saw them. They did, however, feel that the presence of roadside
Driver Reviver sites acted as a reminder of the issue of fatigue.
“Approaching a rest area, or a reviver stop you make a conscious assessment of how you’re
feeling and whether or not you need to stop” – Male, Empty Nester, Wagga Wagga
Advertising was another main reminder of the issue of fatigue. While the majority of group participants
appeared to be aware of at least some form of public education campaign, awareness of the current
campaign was low. While there was also not prominent recall of other messaging, participants made
reference to a number of different campaigns such as:
Dr Karl and Microsleeps;
The Dr Owler advertising;
The line “Don’t die for a deadline”; and
The ‘Kombi Van’ ad.
Of these, recall of the Dr Karl campaign was the strongest – particularly amongst the younger males. He
was considered to be somewhat of a spokesperson for the issue and was highly regarded, although he
was recognized as being less prominent (in relation to driver fatigue) in recent times.

2.2. The Perceived Importance of Driving Techniques
When asked about safe driving techniques, those which gained the greatest level of importance
amongst respondents were ‘keeping below the legal blood alcohol limit’ (90% rated it of high
importance); ‘if feeling tired, pulling over and resting or swapping drivers’ (85%), and ‘maintaining a safe
following distance from the vehicle in front’ (84%, see Figure 21). Only 64% rated ‘never start a trip if
you’re already feeling tired’ as high importance.
Overall, younger male drivers (aged 17-29 years), rated all of the factors significantly lower in terms of
importance, than the total respondent base (Table A16). Young males also rated ‘if feeling tired when
driving, pull over and rest or swap driving’ on par with ‘not using a mobile phone when driving’ (56%
versus 55% respectively).

2.3. Perceived Dangers of various Situations that Could Result in Driver Fatigue
The majority of respondents indicated from a list of statements that ‘starting the trip with sleep debt’
(63%), ‘not taking a break from driving when feeling tired’ (54%) and ‘driving for 6 hours non-stop’ (60%)
were ‘very dangerous’ when taking a long trip of two hours or more (Figure 22).
42
TfNSW Driver Fatigue Study September 2012
‘Driving at a time when you would normally be sleeping’ (42%), ‘not having regular breaks’ (36%), and
‘beginning a trip after work’ (35%) were seen to be ‘very dangerous’ by over a third of drivers, whilst a
further third or so rated these situations as ‘dangerous’.
‘Beginning a trip very early in the morning’ and ‘driving during the daytime when likely to be sleepy’
were more likely to be considered to be ‘not very dangerous’ (49% and 42% respectively) or ‘not at all
dangerous’ (21% and 6% respectively).
Potentially as a result of their sense of invincibility (as revealed in the mini groups), overall younger male
respondents (17-29 years), were less likely to perceive the listed situations as dangerous, particularly
when it came to ‘driving after working all day’ (49% considered it dangerous), or ‘driving during the
daytime when likely to be sleepy’ (40%). However, they were more likely to see ‘beginning a trip early in
the morning’ as more dangerous than other age groups (41%, see Table A30), which is in-line with their
reported propensity not to pre-prepare, and therefore not get a good night sleep (as revealed in the
mini groups).

2.4. Driver Behaviour Index
The survey measured a number of self-reported driver behaviours that were related to driver fatigue. In
2006, a single summary measure of various behavioural questions was developed that reflected each
individual’s claimed behaviours in relation to preventing driver fatigue, and the same base questions
were incorporated in the 2012 study to allow for the Driver Behaviour Index to be reproduced. As was
done in 2006, the Driver Behaviour Index that resulted was then divided into three approximately equal
size groups (see Appendix 5 for details).
The areas that the Driver Behaviour Index covers includes:
self-reported driving when tired,
reactions to driver fatigue warning signs when driving,
44
TfNSW Driver Fatigue Study September 2012
preventative measures taken before driving and while driving, and
usual behaviours while driving.
These measures were combined into a single score out of 100 measuring the degree to which drivers
engaged in negative behaviours with regard to driver fatigue. The higher the score the more likely a
driver was to engage in risky behaviours and the less likely they were to take steps to prevent fatigue.
The score average was 53 (SD = 13.4) and ranged from 23 to 94. The Driver Behaviour Index has been
used to stratify drivers into three equal sized groups - positive behaviours, average, and negative
behaviours.
As shown in Figure 24, respondents aged 17-49 years exhibited negative behaviour significantly more
often (44%) compared to respondents aged over 50 years who exhibited significantly less (15%).
Younger males (aged 17-29) and those in the mid age category (30-49) were significantly more likely to
exhibit negative behaviour on this index, but those aged 50 or over were more likely to exhibit positive
behaviour (49%).
Similarly, amongst the female respondents (Table A15), the younger respondents had the highest
proportion of negative behaviour (57%), while those aged 50 or over had the lowest proportion (10%).
The respondents in metropolitan areas also indicated a higher proportion of negative behaviours than
the regional drivers (35% and 25% respectively).

3. Personal Experiences with Driver Fatigue
3.1. Incidence of Experiencing Driver Fatigue
The incidence of reporting driving while fatigued has dropped considerably since 2006. Six years ago the
proportion of NSW drivers who claimed to have driven when feeling ‘quite tired’ was 40% during a short
trip, and 43% during a long trip. This year those figures dropped to 34% and 35% respectively (see
Figure 25).
The incidence of having driven fatigued during a long trip in the last 12 months was highest amongst
17-29 year old females (52%) and lowest amongst female drivers over 50 years (19%, see Table A17).
Males aged 30-49, and those aged 17-29 were more likely to have experienced fatigue on a long trip
(48% and 41% respectively).

The mini group participants were quite open to discussing their near misses that resulted from driver
fatigue, and in the survey over one in ten drivers (13%) admitted to having crashed or almost crashed
due to fatigue while driving (compared to 7% in the 2006 study, Figure 26). The reported incidence of
fatigue related crashes or near crashes was highest amongst males both 17-29 years (16%) and 30-49
years (18%, see Table A33).
A slight wording change in 2006 meant that respondents were only asked whether they had experienced
an ‘accident or crash’ due to fatigue, whereas in 2001 and 2012 both ‘near miss’ and ‘crash’ due to
fatigue were asked (separately in 2001 and as one question in 2012). This could account for the
*not asked in 2001
46

significantly lower incidence rate recorded for 2006. The incidence of fatigue causing a crash/near miss
in 2012 is still significantly lower than the recorded rate in 2001.

The reported time that had elapsed since the last fatigue related incident was typically over 5 years ago,
with 20% of drivers claiming it was 5 -10 years ago and a further 30% of respondents reporting it to have
been more than 10 years ago (see Figure 27).
However, 15% of drivers claimed that their fatigue related incident was less than a year ago, with this
being highest amongst females aged 17-29 (31% were less than a year ago) and males 17-29 years old
(24% less than a year ago, see table A34).

The mini group participants were recruited on the basis that they had reported feeling tired when
driving on a long trip in the last 6 months, so it was not surprising that they were generally open about
47
TfNSW Driver Fatigue Study September 2012
their own driving experiences with fatigue and (for some) the minor incidents that had resulted from
this. Drivers openly discussed how much of a scare they had had due to their fatigue related experience,
particularly if it had been a microsleep.
“I’ll admit that I’ve found myself getting really drowsy sometimes. You know, when you find
yourself nodding off for a fraction of a second” – Male, Single/Couple, Newcastle
“I get bored with driving, and I can feel tired even driving to work” – Male, Family, Parramatta
After experiencing a fatigue related incident, participants indicated that they were now more aware of
the issue and more likely to take action when they noticed they were experiencing fatigue related
symptoms. However, even though some of the younger drivers admitted to experiencing severe fatigue
symptoms, they were still reluctant to alter their behaviour as a result.
“I actually had a bit of a crash because I was falling asleep at the wheel, but that was a one-off”
– Female, Single/Couple, Parramatta
The younger drivers were more likely to indicate that they were quite happy to drive while a bit tired.
However, some also indicated that they found it difficult to know exactly at what level the tiredness
became an issue.
“I work hard and I’m always tired. That doesn’t mean I’m not going to drive. It’s just part of life.
But maybe there’s a point where it’s worse than normal. I’m not sure” – Male, Single/Couple,
Wagga Wagga
Another interesting aspect raised by the mini group participants was that the incidents and near misses
due to fatigue were often not discussed or admitted to amongst their family or friends. As a result they
indicated that any word of mouth component to demonstrate how widespread fatigue experiences are,
was quite low.
“Someone might say that a drive to Melbourne was a bit tough, but they’re not going to say that
they nearly nodded off and needed to stop” – Male, Family, Parramatta
Frequency of Experiencing Driver Fatigue
Almost one in ten respondents who had indicated that they felt a bit tired on long trip went on to reveal
that this occurred ‘very often’ or ‘often’ (see Figure 28), with this being more prevalent amongst males
30-49 years (15%) and females over 50 years (16%, see Table A18)
Over 45% of those who admitted to feeling tired indicated that they experienced fatigue ‘sometimes’
whilst driving, and over 40% claimed they only felt tired on long trips whilst driving ‘rarely’ or ‘very
rarely’.

Time of Day of Driver Fatigue Experiences
The peak time for experiencing driver fatigue was in the afternoon in the case of both long (33%) and
short trips (24%, Figure 30). The next most common time mentioned by drivers for feeling tired while
driving was early in the morning for shorter trips (19%), but dusk/twilight (18%) or evening (17%) in the
case of long trips.
Young male drivers 17-29 years were more likely than the total respondent base to say they experienced
fatigue in the morning (9am-12noon). Given that they reported a lower frequency of driving at night
(Table A4), it is not surprising that females aged 50 or over were more likely to be fatigued between
12noon and 4pm (44%, see Table A18).

The mini group participants also suggested that the afternoon or early evening period was the time at
which they started to feel tired whilst driving. Many, particularly the older group members, suggested
that they often tried to time their trips in order to arrive at their destination in the afternoon in
recognition that they would be starting to fatigue around about this time.
Very few drivers in fact, reported feeling comfortable driving at night because of decreased visibility but
also because of the increased possibility of driving fatigued.

3.2. Common Causes of Driver Fatigue
When asked what they perceive to be the most common causes of driver fatigue, around half of drivers
spontaneously mentioned ‘lack of sleep’ (51%, Table 1). ‘Driving for too long without a stop’ was the
next most frequently cited cause (30%) with this reason being more likely to be mentioned by older
(50+) drivers.
‘Stress’ (14%) and ‘alcohol/hangovers’ (10%) were offered as causes by over ten percent of respondents,
with the latter reason being more often cited by older drivers over 50 years.
Other causes of driver fatigue mentioned fairly frequently included ‘starting off tired’ (6%),
‘boredom/lack of stimulation’ (5%) and ‘not enough concentration/focus’ (5%).
While only 6% of all respondents were unable to nominate a cause, this was significantly higher amongst
males aged 17-29 (17%).

Sleep Debt
The survey respondents also appeared to have a reasonable knowledge of the term ‘sleep debt’. When
asked to describe the term, the two most commonly given definitions were ‘lack of sleep/less than
required’ (44%, Table 2) and ‘not having enough sleep over several days’ (26%). Other descriptions were
of a similar nature and included definitions such as, ‘a build up of insufficient sleep’ (10%), ‘catching up
on sleep later’ (5%), owing ‘sleep to your body’ (4%), ‘sleep deprivation’ (3%) and ‘hours of sleep you are
lacking’ (3%).
Discussion of the term within the mini groups also revealed that while it was not something that
participants used in everyday conversation, it was understood by all, and most were able to verbalise a
definition of sleep debt as being a lack of sleep built up over a number of days.
“It’s pretty self-explanatory really. If you don’t sleep well over a period of time you start to feel
tired and run down” – Female, Family, Newcastle
However male respondents aged 17-29 were less knowledgeable, with nearly one third (31%) of this
segment claiming not to know what sleep debt meant.

After reading a description of sleep debt (a lack of sleep built up over a number of days), respondents
were asked if they had ever experienced it. Figure 31 shows that the majority of drivers had
experienced slept debt at some point, with 7% experiencing it ‘very frequently’, 12% ‘fairly often’ and a
third (33%) ‘sometimes’.
Sleep debt experiences were marginally more regular amongst younger males (17-29 years) with one in
ten claiming to experience it ‘very frequently’ (Figure 31, and Table A22).

Base: All survey respondents (n=1002) Q12b. Sleep debt means a lack of sleep built up over a number of days. Have you ever experienced sleep debt?
Despite being familiar with sleep debt, most participants did not see it as a major issue for their driving,
and as has been mentioned, some participants specifically included a good night sleep in their
preparations before taking a long driving trip. A clear exception to this could be seen with some of the
younger males who did appear to be impacted by sleep debt, despite not necessarily seeing it as an
issue. A few referenced instances of having several ‘big nights’ in a row before driving long distances,
and only recognising in hindsight that their poor preparation in this regard may have influenced their
driving ability. Even so, these participants generally felt that they were capable of handling themselves
when they were sleep deprived.

3.3. Early Warning Signs of Driver Fatigue
When drivers were asked to name the early warning signs of driver fatigue, there appeared to be a good
level of understanding of the symptoms and signs, with most being able to mention at least one or two.
‘Yawning’ (45%) and ‘difficulty focusing’ (40%) were the two signs most frequently mentioned by
drivers, followed by specific issues to do with their eyes, ‘tired/ sore eyes/rubbing eyes’ (25%) and
‘closing eyes/droopy’ (17%). ‘Drowsiness’, ‘restlessness’ and ‘drifting in your lane’ were also mentioned
by around one in ten drivers, however actual ‘microsleeps’ were only cited as a sign by 4% of NSW
drivers (see Table 3).
Those less familiar with the early warning signs tended to be younger males, with over a quarter (28%)
of them unable to mention a sign of fatigue.

54
TfNSW Driver Fatigue Study September 2012
Respondents were asked in the survey if they had actually experienced any signs of fatigue from a given
list, in the last 12 months while driving. The majority (60%) of drivers claimed to have experienced
‘yawning’ and a further 40% of drivers reported having ‘sore or tired eyes’ (see Figure 32).
Around one third of respondents had experienced signs such as ‘poor concentration’ (36%), ‘boredom’
(35%), ‘drowsiness’ (33%) and ‘restlessness’ (30%) while driving in the last 12 months.
‘Microsleeps/falling asleep at the wheel’ had been experienced by over one in ten drivers (12%) in the
past year.

Survey respondents over 50 years of age were less likely to have experienced any of the early warning
signs and were more likely than their younger counterparts to have indicated that they had not
experienced any of them (30%, Table 4). Males in general however, were more likely to have
experienced early warning signs, with males 17-29 years particularly more likely to have experienced
‘boredom’ (49%) and ‘blurred vision’ (27%), while 30-49 year old males were more likely to have
experienced ‘microsleeps’ (19%), ‘having difficulty staying within marked lanes’ (17%) and ‘oversteering’
(12%).

Response to Early Warning Signs of Driver Fatigue
Both the survey respondents and mini group participants revealed not all warning signs were considered
dangerous enough to warrant stopping straight away. When asked if they would stop straight away,
soon after or keep driving when they experienced a particular warning sign, the majority of drivers felt
that they would keep driving or stop soon for over half the signs.
The signs that drivers felt they would be most likely to stop straight away after experiencing were
‘microsleeps’ (86%, Figure 33a), ‘oversteering’ (52%, down from 56% in the 2006 study) and
‘drowsiness’ (50%, down from 66% in the 2006 study). In the case of microsleeps (which was not
measured in the 2006 study), almost one in ten (7%) 17-29 year olds suggested that they would keep
driving after falling asleep at the wheel (Table A25).
Figure 33b also shows that over half of the respondents surveyed indicated that they would stop soon
after if they experienced ‘poor concentration’ (55%), ‘sore or tired eyes’ (63%), ‘restlessness’ (58%), or
‘yawning’ (55%).

The mini group participants were also asked to rank the early warning signs in terms of their perceived
severity and likelihood of making them stop for a break.
Microsleeps, double/blurred vision, and drifting across lanes were warning signs that were seen to be
quite severe and required an immediate stop/break before driving could recommence. Some also felt
that a momentary loss of awareness of surroundings would require the same response.
However, forgetting sections of a driving experience was not felt to be that uncommon (particularly
amongst the younger drivers), and this aspect was generally placed more mid-range in the severity
rankings. So too the signs of sore/heavy/tired eyes, momentary lacks in concentration, slow reaction
times, sore limb(s), slight drowsiness, headaches, and yawning were also generally seen to be mid
ranking. As such the required response from such signs was seen to be to take a break, but not
necessarily immediately.
Other signs identified included finding the car speed to be altering, general boredom, feeling
frustrated/agitated/irritable, and generally restless and fidgety. These signs however, were seen to be
quite low on the severity scale, and as such were not felt to require any real action in response.
Interestingly however, while there were a number of signs identified that were not felt in isolation to
require any real immediate response, participants indicated that when the signs were combined, they
would be more likely to be seen as more severe, and lead them to stop and take a break. This effect of
having a ‘combination of symptoms’ was more likely to be mentioned by the older participants – with
younger drivers (males particularly) expressing a strong desire to resist ‘minor’ warning signs (even in
Poor concentration Boredom Yawning Restlessness
58
TfNSW Driver Fatigue Study September 2012
combination), and to push on to their final destination or what they termed an essential stop (needing
to go to the toilet etc.).
3.4. Reasons for Driving While Fatigued
Reasons for driving while fatigued were discussed primarily in the context of continuing to drive after
fatigue signs had been experienced. However, while not necessarily a pre-determined area of
exploration for the mini groups, the discussion process sometimes covered situations where participants
had commenced a trip knowing full-well that they were not totally alert. As an example, one participant
indicated that they had set out early one morning to play a round of golf, and ended up falling asleep by
the side of the road. The motivators behind this sort of behaviour though, can be seen to be in-line with
the reasons motivators outlined below (e.g. in this case, adhering to deadlines/commitments, and a
belief that they will feel ‘awake’ in due course).
Pre-determined responses in the survey also focussed on continuing to drive when already fatigued, and
‘having nowhere to stop’ (55%) and being ‘close to reaching the destination’ (45%) were the two main
reasons respondents selected. Respondents also indicated that they would continue driving fatigued
because they were ‘not feeling tired enough’ (33%), ‘didn’t feel safe stopping in a rest area’ (27%) or
because they simply ‘wanted to get the journey over with’ (27%, see Figure 34).
Drivers were less likely to select ‘not believing I will have a crash’ (11%) or ‘having to meet a deadline’
(16%) as reasons for not stopping when tired.
The perception of having ‘nowhere to stop’ was greater amongst the older age groups (57% amongst
males over 50 years; 61% amongst females over 50 years), while ‘not wanting to waste time’ was more
likely to be the case for the younger 17-29 years olds (30% amongst 17-29 year old males; 29% amongst
17-29 year old females; see table A26).
Within the group discussions, whilst a number of participants held a perception that there was ‘nowhere
to stop’, it seemed that (particularly amongst the older drivers) it was more of a perception that there
was nowhere suitable to stop other than fast food outlets or at service centres. The lack of pre-trip
preparation in planning potential stops (particularly amongst the younger participants) may also have
contributed to his perception, as by the time they felt that they needed to stop, there may not be any
stopping opportunities nearby.

%
Base: All survey respondents (n=1002) Q16. For which of the following reasons might you continue to drive rather than take a break if you were feeling tired?
Many of the mini group participants openly stated they had driven when tired. When discussing why
this occurred, and why they begin a journey when already tired or push on when they know that they
should stop, many different reasons emerged:
Adhering to Deadlines/Commitments
This was a common reason, especially when family and friends were felt to be relying on them (e.g.
to turn up to a wedding), or in cases where they were required to be somewhere at a certain time
(e.g. getting to work, or picking up their children). While they realised that deadlines can be moved,
participants expressed a need to avoid letting other people down.
“You can’t just not show, so you make the effort. It would be a bit soft to say that you couldn’t make
it on time because you had to stop for a powernap”. – Male, Single/Couple, Newcastle
Inexperience
Whilst many of the younger participants knew of the early warning signs of fatigue, some of the less
experienced drivers did not seem to be making the connection between the warning signs and
microsleeps. That is, they did not seem to have a grasp of when the signs became significant
enough to warrant action, and so appeared to be underestimating the severity of the situation.
“I know when I am tired but I’ve never had a microsleep so I wouldn’t know if I am that bad” –
Female, Single/Couple, Parramatta
60
TfNSW Driver Fatigue Study September 2012
A Belief That Drivers Will Feel ‘Awake’ in Due Course
Those who set out to beat the traffic were open to admitting that they sometimes felt tired before
they departed, but left anyway under the assumption that they would wake up as they went along.
Young males in particular, admitted to jumping in the car after only a few hours sleep the night
before, despite the fact they were setting off mid-morning.
“It’s how I feel pretty much every day. It takes me a while to get going…. but I’m not going to sit
around and wait before I set off. Driving wakes you up” – Male, Single, Sydney CBD
Peer Pressure/Family Pressures
Those with children mentioned that they sometimes had an added pressure of getting the children
home or to end the journey. Those who drove with friends also talked of pressure to continue on
and not ‘unnecessarily’ extend the journey by stopping.
“I don’t want to put everyone out by stopping” – Female, Family, Newcastle
Concern Over Safety
While there were some general mentions of not feeling safe just stopping to rest on the side of the
road, particularly on an expressway, due to the risk of being hit by another vehicle, a few of the
younger females did not think unmanned rest stops were a safe place to stop (particularly at night,
or when on their own). However, they did not tend to plan their stops to ensure they could pull
over somewhere safe when they needed a break.
“As a single female I don’t think I’d go near them stops at night. They’re removed from the traffic,
and there’s usually just one or two cars or trucks in them. I don’t think they look safe at all” -
Female, Single/Couple, Parramatta
Anticipation of Getting Home
Some participants also described the ‘excitement’ of nearing home, and the desire to reach the end
of their trip so that they would then be able to relax. They felt that the ‘pull factor’ in such a
situation would often be enough to keep them going.
“I’d rather get home and get a solid sleep in my bed than have half an hour on the side of the road”
– Male, Single/Couple, Wagga Wagga
Beat the GPS
Some participants also indicated that they knew how long a trip should take (from experience,
route planners or by checking their GPS device) and had a desire to match or even beat the
expected trip time - even to the extent of deriving a sense of satisfaction when this was achieved.
61
TfNSW Driver Fatigue Study September 2012
“It feels good to know you’ve taken 10 minutes off your trip”. – Female, Single/Couple, Parramatta
“You just need to get to that chequered flag as fast as you can” – Male, Single, Sydney
Avoiding Frustration
Some drivers (most likely to be males) also indicated that they were less likely to stop if they had
been dealing with traffic and/or difficult vehicles along the length of their trip, because if they were
to pull aside it would result in them having to re-experience the difficulty they had just encountered
(i.e. by overtaking the same vehicles again).
“If it’s just taken you 10 minutes to get in front of a caravan, you don’t want to pull over and let it
pass you” –Male, Family, Parramatta
A Sense of Pride
Amongst young males and a few of the older males, there was also a sense of having to prove
themselves by pushing on. Many spoke of not wanting to appear to be weak and incapable of
driving long stints, particularly in front of others.
“You don’t want to seem weak to your mates” – Male, Single/Couple, Newcastle
Invincibility
Younger males and some younger females revealed a sense that crashing due to fatigue ‘won’t
happen to me’ - which seemed to stem from them generally having done it before without any
issue. This led them to believe that they could easily do it again without issue.
“I’m capable of understanding my own threshold” – Male, Single, Sydney CBD
“I’m used to driving long distances so I can drive for longer than others” – Male, Single/Couple,
Wagga Wagga
Inconvenience and not wanting to waste time
The majority perceived stopping as a waste of time. Even a short toilet break or petrol stop was felt
to add significantly to a trip (in the vicinity of 20 to 30 minutes). In that sense there was a strong
desire expressed for people to push on where they possibly could.
“Its easy to get behind if you make a stop, so you try and keep your stops to as few as possible” –
Male, Family, Parramatta
A feeling that there is nowhere to stop
This was also expressed (quite prominently) in the survey results. However, while the mini group
participants suggested that there actually were places for them to stop if they really had to, they
62
TfNSW Driver Fatigue Study September 2012
felt that it was difficult to find places that met all of their requirements for a stop. That is, they were
looking for locations that served decent food and good coffee etc. Most potential stop locations
were seen to be at large service centres, which were felt to be convenient location wise, but lacking
somewhat in terms of what they offer.
The lack of pre planning trip stops may also have contributed to this perception as some described
having no stopping options nearby when they finally decided that they needed a break/stop.
“You don’t have the sort of choice that you used to going through the small towns” – Male, Empty
Nester, Wagga Wagga
Not wanting to stop too frequently
Another general barrier expressed came more from the younger participants who tended to see
their long driving trips more of a chore than those of the older participants (who sometimes
incorporated the travel into the enjoyment of a trip). The younger and regional participants
generally wanted to minimize the frequency with which they stopped – especially if they had
passengers as they didn’t want to inconvenience others – and so most felt that they did not want to
stop every couple of hours.
“I know they say to stop every two hours, but for us you would never get anywhere” – Male, Empty
Nester, Wagga Wagga
Continuing to Drive When Fatigued
The average time away from a destination survey respondents suggested that they would ‘push on’
rather than stop even if they were tired was 55 minutes, with this raising significantly to an average 78
minutes amongst males 17-29 years and 68 minutes for males 30-49 years old. Older (50+) drivers were
more likely to stop earlier, claiming if an average of 50 minutes away from a destination, they would
continue to drive if tired (see Figure 35).
Figure 35: Acceptable Distance Away from Destination to 'Push On' - Average Minutes
Base: All survey respondents (n=1002) Q17a. If you recognised that you were tired while driving on a long trip, how close would you have to be from your destination to ‘push on’ rather than take a break?
63
TfNSW Driver Fatigue Study September 2012
3.5. Motivators to Stop Driving When Fatigued
Even if close to their destination, respondents were asked which motivators from a given list would
actually make them stop if they were tired. Not surprisingly, 79% stated a ‘microsleep’ would force
them to pull over and 71% would stop if they almost crashed (see Figure 36).
Other fatigue signs such as ‘poor concentration’ (48%), ‘pressure from other passengers’ (47%) and ‘sore
or tired eyes’ (27%) emerged as less motivating than the ‘need for toilet break’ (61%).
Of concern was the higher proportion of 17-29 year old males (12%) who suggested that ‘nothing’ would
make them stop if they were close to their destination (Table A28).

4. Potential Countermeasures for Driver Fatigue
4.1. Support for Making Driving When Fatigued Illegal
Approximately half of all respondents (52%) supported the idea of making it illegal to drive while
fatigued (see Figure 37). Greatest support came from those over 50 years (59%).
Support was lowest amongst respondents aged 17-29 years, particularly the males (35%, compared to
43% of females in that age group). Respondents residing in regional areas were also more likely to be in
support of the idea compared with metropolitan residents (58% versus 50% for metro, see Table A33).
General support for legislation dropped dramatically from 2006 where all age groups showed over 75%
support for this countermeasure. This change in support may be due to the slight wording change in the
question where 2006 calls for legislation ‘without having slept in the previous 24h’, whereas 2012 asks
‘when fatigued’.

Base: All survey respondents as shown. Q (2006) In principle, would you support making it illegal to drive a vehicle without having slept in the previous 24hours? Q (2012) In principle, would you support making it illegal to drive when fatigued?
Respondents in support of making driver fatigue illegal were presented with two ideas for potential
definitions of ‘fatigued’ (see Figure 38). Overall there was not a great deal of difference between
preference levels for the two definitions, although there was a slightly higher preference for ‘driving
after being awake for 17 hours’ (48%) rather than ‘driving having not slept in the last 24 hours’ (44%).
Preferences for the legal definition of driving when fatigued did not vary significantly by age, gender or location (see Table A34).

Base: Respondents in support (n=527). Q23b. If it were to be illegal, how do you think ‘driving while fatigued’ should be defined?
(Prompted)
The main reason respondents did not support making ‘driving when fatigued’ illegal in principle, was
because it was felt to be too hard to police, judge or define (54%, Table 5). Further reasons for a lack of
support were because it was felt that there are too many fines or rules already (10%); that people have
different tolerances to fatigue (10%); and because sometimes you just need to keep driving (9%).
Those tending to suggest that driving when fatigued would be too hard to police/judge were males aged
30-49 years (62%) and regional respondents (70%, see Table A35).

The mini group participants were also asked what measures could be undertaken to encourage people
not to drive when fatigued. Without any prompting, in almost all groups the suggestion was made to
introduce some form of legal enforcement measure. While participants weren’t too sure if or how this
could ever be policed, they suggested that if it was achievable it would help to raise the profile of the
issue and reinforce its importance.
“If it was illegal and they could actually tell, then that would work” – Male, Retiree, Sydney CBD
“Maybe if your car doesn’t start until you pass some sort of alertness test” – Male, Family,
Parramatta
Related to this, though not necessarily a formal form of enforcement, some also felt that Police
presence in general tended to result in drivers being more aware of their driving behaviour and
compliant with driving rules. As such, they suggested that simply having more Police presence on the
road would (by default) lessen the incidence of fatigue related crashes.
Potential Penalties for Driving When Fatigued
The most appropriate penalty for driving while fatigued was felt to be a fine (66%) or loss of demerit
points (65%, Figure 39). The idea of a fine was less likely to be considered appropriate amongst younger
males aged 17-29 years (48%) and older females aged 50 + years (54%, see Table A36). Loss of demerit
points was also less likely to be considered appropriate by younger males (36%).

4.2. Other Potential Countermeasures
Apart from enforcement as already discussed, there were a range of other suggestions to emerge from
the group discussions that were felt to have the ability to encourage compliance and lessen the rate of
fatigue related incidences. These included:
Encouraging Passenger Involvement
The suggestion was made within a few of the group discussions to encourage passengers to play a
greater role in influencing drivers to take a break by being more attentive of the driver’s condition,
and then suggesting when breaks should be taken. This was felt to have the ability to lessen the
pride barrier that the driver may display by allowing them the option of stopping because someone
else had suggested it (rather than the driver imposing a stop and inconveniencing their passengers).
It was felt that this could be achieved by educating children and passengers to speak up and suggest
the need to swap drivers or stop and take a break.
Promotion of Detours and Scenic Stops
While some of the older participants were viewing the drive to their destination as part of the
overall experience they were having, this clearly wasn’t the case for all drivers. Many participants
simply saw the trip as a means of getting to where they wanted to go, and not feeling any form of
pleasure in the drive itself. As such, there were some suggestions of encouraging drivers to change
this perspective, and to allow more time for travel so that the drive itself could become part of the
overall (hopefully pleasurable) experience that they were seeking. As there was recognition that
drivers were reluctant to venture far from the highway, it was felt that promotion of quality stops
and experiences along popular routes may assist in encouraging drivers to stop and experience
different things along their trip.
Education Campaigns
Participants ultimately came to the conclusions that further education was required to increase
general public awareness and knowledge of driver fatigue as an issue. The most common suggestion
to emerge was for the use of ‘hard-hitting’ graphic style advertising to act as a reminder of the
potential consequences of driver fatigue. However, others felt that graphic advertising was all too
common these days, and felt that a more straightforward approach would be more beneficial.
This, it was suggested could have an emphasis on the prevalence of fatigue by the use of statistics
that could be used to compare the issue with other more top-of-mind issues such as speed or
alcohol. As an example, some of the younger participants recalled a statistic (potentially from the
Road Users handbook) that equates driving after an extended period with no sleep with a certain
level blood alcohol content. Alternately, some of the younger participants felt that a campaign
should be developed to make driving while fatigued socially unacceptable, as they felt was achieved
with speeding through the Pinkie campaign.

TfNSW Driver Fatigue Study September 2012
More Driver Reviver Stops
There were also suggestions that greater use could be made of Driver Reviver stops. Some felt that
these were currently under-manned and under-utilised and others were simply suggesting that
more of these sorts of stopping opportunities should be provided. However, it was also suggested
that not only should more stops be provided, but also that better facilitates be made available, with
more comfortable seating, and perhaps better tea and coffee, as well as energy drinks and cakes for
sale to encourage stopping. Some participants suggested that there needed to be better signage of
these areas to offer an early warning that one is approaching. A few of the participants who had
driven through Victoria also spoke of the term ‘Powernap Bay’ that are used in this State to
encourage people to take a serious rest (not just stretch their legs).
Message Boards
The other main suggestion to emerge was for greater use of road side messaging to remind people
to stop. Some took this concept further and also thought that there was potential for point to point
cameras to be used to identify drivers that had been driving for extended periods without a break -
and for message boards to suggest (to those specific cars) to rest soon.

Discussion and Conclusions
From the findings of the research there were a number of issues that emerged for consideration:
1. The notion of a short trip was an ambiguous one. In the survey, it was defined as anytime drivers
were in the car travelling for less than two hours within their home city/town, however findings
suggest that ‘trips’ are seen to be more for special occasions or the ‘out of the ordinary’ journeys.
In any future research or communication, caution will need to be taken when using the term
‘short trip’. It will need to be defined clearly as to what is meant by the term in a way that is not
open to misinterpretation.
2. In addition, ‘short trips’ were not regarded as requiring a break of any kind. Drivers did not even
consider factoring in a break whilst driving on a short trip.
In that regard, any future communication should give consideration to alerting drivers to the
dangers of fatigue in any situation - by suggesting that it is not only an issue on long trips, but on
short trips as well.
3. Whilst drivers were spending some time preparing for their long trips, the focus of preparation was
on ensuring that the car was in order, that there were snacks and drinks available for the trip, and
that they were familiar with the route and the time it will take. There appeared to be little pre-
planning in terms of formalised selection of stops or breaks along the way or even planning time in
the journey for those breaks.
There may be merit in devising a strategy aimed at encouraging drivers to pre-plan regular rests or
breaks, or at least time for them, within their trip.
4. Unless the warning signs were considered severe (e.g. experiencing drowsiness, oversteering or a
microsleep), drivers tended to keep ‘pushing on’. Less severe symptoms of fatigue were ignored and
many did not know when being tired was too tired. That is, when the chance of a microsleep is high.
There is an opportunity to communicate the ease with which a microsleep can occur when tired
and strongly link other signs of fatigue with the onset of microsleeps.
5. The 17-29 year male segment was generally of the mindset that they are somewhat invincible and
therefore capable of ‘pushing on’, even when they do experience signs of fatigue. They were also
less inclined to prepare themselves before taking a long trip.
This sub-group indicated a relatively high incidence of experiencing driver fatigue, particularly in the
morning, and appeared less aware of the ‘early warning signs’ of driver fatigue. Young males were
also less knowledgeable of the exact term sleep debt, although when prompted with a description,
the incidence of having experienced sleep debt was high.
70
TfNSW Driver Fatigue Study September 2012
Consideration should be given to further educating drivers (particularly younger ones) on the signs
of driver fatigue in order to heighten the perceived level of risk associated with experiencing the
‘early warning’ signs and to stress the importance of stopping immediately when those signs
appear, no matter how long the trip; not to push on when close to reaching their destination.
6. Young males in particular, suggested that they carry on driving even when tired for fear of being seen to be weak or unable to handle the drive. In that respect the peer pressure to demonstrate that you can keep going was quite strong.
Perhaps this peer pressure can be harnessed to stop drivers from pushing on by devising a strategy specifically targeted at young male drivers who are too proud to take a break. This level of peer pressure could also be encouraged to come from passengers who could embarrass the driver into taking a break.
7. When compared with driving under the influence of alcohol and to some extent speeding, driving
fatigued was not considered as serious. The factors that contributed to that perception were that
there were no laws against it, fatigue related incidences were not as high profile in the media, and
public fatigue related campaign awareness was low.
We would suggest consideration be given to using future communication to lift the seriousness
and prevalence of driver related fatigue crashes and perhaps utilising comparisons of driver
fatigue to driving with a high blood alcohol level or at high speeds.
8. Of the campaigns, the Dr Karl campaign was the most well recalled, and the most prominent
residual messaging from this campaign was that of microsleeps and the night time setting. There
was also a perception that the risk of a microsleep is much greater in the evening (which appears to
have been fuelled by advertising featuring Dr Karl’s reference to circadian rhythms), so much so that
many drivers try to time their arrival before dusk. However, many drivers also indicated
experiencing fatigue when driving in the afternoon.
In future communication, it may be beneficial to highlight the dangers of fatigue during the
afternoon as drivers believed they were already more cautious at night and associated
microsleeps more with night time driving.

Appendix 2 – Qualitative Pre-task Questionnaire
PROJECT ‘NSW DIVERS’ – PRE GROUP TASK Overall Instructions This is a short exercise designed to get you to think about some of your more recent driving experiences which will then be explored further in the group discussion you are due to attend. Within the group discussion we will be concentrating on your experiences in driving on ‘long trips’ - for the purposes of our study these have been defined as journeys longer than two hours (generally outside your home city or town).
Please complete this questionnaire prior to attending the group. Completed questionnaire will be collected prior to the group discussion.
Note that none of your personal details will be in any way be connected with your responses, and it’s important that your answers are as open and honest as possible.
Please think about your most recent ‘long trip’ driving experience, and complete the following: Part 1 – Planning for Your Trip
How far in advance did you plan your most recent long trip?
Months: Weeks: Days:
In what way did you plan for your journey?

Appendix 3 – Qualitative Pre-task Summary of Outcomes
Trip Planning
The majority of planning for long trips was undertaken for a period up to two weeks before
departure, with most planning relating to preparation of vehicles, and planning of destination details
(accommodation and activities).
Males were more likely than females to indicate that they did not do any pre-planning for their trip.
Trip Distances and Times
The majority were undertaking trips of more than 400km.
More than one in ten were for distances in excess of 1,000 km.
Most trips were greater than three hours in duration.
A few were undertaking trips over a day in length.
Passengers and Driver Sharing
Males were most likely to travel by themselves, in fact, around two thirds of trips by males were
undertaken by a single driver.
Most others travelled with one or two other passengers (spouse and/or child, or friend).
However, a reasonably large proportion drove with 4 or more.
Stops Made
Relatively few drove straight through, however around one in five only made one stop.
Participants were most likely to have made two stops on their trip.
103
TfNSW Driver Fatigue Study September 2012
Reasons for Stopping
Most first stops were for toilet breaks.
Fuel and food became more prevalent with subsequent stops.
Interestingly, few referenced the need to stretch, relax or refresh themselves as a reason for
stopping.
Longest Driving Time
For most the longest stretch of driving was around 2 hours (or less).
However, almost one in five had driven for a four hour (or more) stint (most likely to be males).
How They Were Feeling During the Trip
Feelings at the Start of the Trip
The vast majority indicated feeling ‘refreshed’ or ‘normal’ at the start of their trip.
However, around one in ten indicated that they were ‘slightly tired/drowsy’ at the outset.
Feelings Half Way Through the Trip
The majority indicated feeling that they felt ‘normal’ mid way through their trip.
However, around one third were either ‘restless’ or ‘slightly tired/drowsy’.
Feelings at the End of the Trip
Only around one quarter indicated that they still felt ‘normal’.
Most were ‘slightly tired/drowsy’ or ‘exhausted’.
