• More mobile phones than people in the US (2011) .
• Up to 28% of vehicle crash risk attributable to distraction from cell phone use or text messaging.

• Risk of distraction – Naturalistic study of
truckers– Cell phone use was
more common than texting, so greater overall risk.
– Relative crash risk highest for texting.
• Text messaging had the longest duration of eyes off road (VTTI)

4 “E”s OF INJURY PREVENTION
• Education
• Enforcement
• Physical Environment
• Social Environment
Changing Behaviors
HARD TO CHANGE THIS RISKY BEHAVIOR
• Drivers know texting and talking on a cell phone is dangerous
• Drivers know texting and talking on a handheld phone is illegal
• Drivers are irritated at the distracted driving around them
Yet….• They continue to talk and text
while driving
24
1. “Habit” of picking up the device to answer is hard to suppress
2. Holding phone is physical (eyes off the road, hand off the wheel) and cognitive distraction
CELL PHONE/TEXTING CAN BE COMPULSIVE
[After pulling over a driver, he waved to let me know]….”I know you’re back there, but I’ve got to finish this phone conversation”.“When is it a big enough deal to realize that we need to draw a line in the sand? We can either stop [texting/talking] in the hopes that we’ll have fewer crashes, or we just have to agree that we all might lose some family members because it’s so important that we text.”
“You’ve just got to answer that phone, you’ve got to get that next call. It’s the same like you’ve got to get the next hit of heroin”

DEVELOPING MARKETING STRATEGIES FOR REDUCING DISTRACTED DRIVING
Big Fat Tobacco Wants to Control You
27
• Learn from what has worked• Drunk driving• Seat belt use
• Barriers• I’m a better/safer driver than others• My calls are “important”• Compulsive habit
WHAT WORKS TO CURB DISTRACTED DRIVING?

Enforcement

Social Environment
4 “E’s” OF INJURY PREVENTION
29
• General education on why reducing distraction is an important public health problem
• Opportunities for parent role-model; review family commitment to distraction-free driving
• There’s an app for that: technological solutions
• Education on risk of citation (not crash)
• Traffic court for distraction?

Goal: Identify strategies for improving implementation and enforcement of distracted driving legislation
IMPROVE ENFORCEMENT
• Survey of WA law enforcement found significant variability in enforcement practices
• Significant variation in prosecution of distraction driving

Washington Case Filings for 'Hand Held Cell Phone Use' Violation

Primary law effective June 10, 2010
Data source: Adminstrative Offices of the Courts (AOC). Number of cases filed under RCW 46.61.667 (using wireless telecommunications device while driving) for violations identified by WSP and local law enforcement. Does not include cases filed in Seattle Municpal Court (SMC).
• Three focus groups held with law enforcement officers in King, Whatcom, and Spokane counties in 2013
OFFICER FOCUS GROUP STUDY
THEME: DRIVERS KNOW LAWS BUT CONTINUE THEIR DISTRACTING PRACTICES
“If you don’t know that there’s a cell phone law in this state you shouldn’t be driving. Because it’s out there... They know it’s a big deal. So give them a ticket.” – WA Officer
“Short of calling 911, there is no excuse. [for using a cell phone while driving]. If you need to be on the phone all day, get a blue tooth.” – WA Officer
36
THEME : ENFORCEMENT CHANGES DRIVER BEHAVIOR
• Behavior change happens when law enforcement and public education go hand in hand.
• Ex: stigma of DUI• Ex: seat belt enforcement
• Most effective enforcement is writing a ticket.
• Traffic school viewed as positive learning experience
“If you give somebody a warning, it’s not going to change their behavior. They’re driving away with an “I got away with it” kind of attitude. - WA officer
“We need to change the way the public sees the importance of traffic enforcement as a whole. Criminals drive cars; normal people drive cars. It is easier to give a criminal a ticket, than a normal person. But normal people kill people because they’re distracted.” - WA officer
• Various levels of enforcement within & between agencies
• “To ear” language in state law
• Proof of texting (drivers “throw” the phone)
• Citation outcomes
• Lack of extra patrol funds
• Law enforcement ‘users’ of in-vehicle technology
ENFORCEMENT CHALLENGES

1. Each law enforcement office adopt policy on distracted driving
2. Track citations and convictions locally
3. Emphasis patrols4. Inform public that laws

TEXTING LEGISLATION
By 2012, forty-five states had a law that bans texting for any group of drivers defined by age or driving experience, up from zero in 2001. LawAtlasSM
20122001
Cell use: A person operating a moving motor vehicle while holding a wireless communications device to his or her ear is guilty of a traffic infraction. (exempts hands-free) (RCW 46.61.667)
Texting: A person operating a moving motor vehicle who, by means of an electronic wireless communications device, sends, reads or writes a text message, is guilty of a traffic infraction. (RCW 46.61.668)
Holders of Instruction Permit or Intermediate License: Cannot use any wireless communication device (regardless if hand-held or hands-free) while driving unless in an emergency situation. (RCW 46.20.055; RCW 46.20.075)
WASHINGTON DISTRACTION LAW
• Local ordinances address ‘inattention’
• Fines vary between $25-$1000 (many limit fine to >$250)
• Fines levied under local ordinances ‘stay local’
• Primary enforcement
LOCAL ORDINANCES – 2 COUNTIES, 44 CITIES
43
1. Drop “phone to ear”; include any talking on handheld device
2. Change “texting” to “manipulating handheld device”
3. Drop “stop sign/signal” exemption
4. Escalating fine ($124 -> $250)5. Consider points on license for
2nd offense6. Decal to identify provisional
license-holders, so laws pertaining to inexperienced drivers can be enforced
HOW COULD THE LAW BE STRENGTHENED?

OFFICER DISTRACTED DRIVING• Minn. Study found distracted
driving contributed to 14% of all claims; 17% of all costs.
• One half of all crashes that involved distraction from technology involved the use of Mobile Data Terminals (MDT’s).
• MDT claims were most expensive, averaging about $10,000 per claim.
Distracted Driving: Law Enforcement’s Achilles’ Heel
46
DISTRACTION ON THE JOB
47
1. Distracted Driving is Impaired Driving• Make distracted driving a priority area
for law enforcement • There are no “safe” distracted drivers• Current law, while not perfect, is
enforceable and prosecutable
2. Adopt distraction policy for officers• Officer as role model• Liability• Loss of vehicle time• Loss of life
3. Review MDT policies• Is there a voice-control option?
ACTION STEPS FOR LEADERSHIP
48
1. Adopt mobile device law similar to Oregon (does not require “phone to ear”; device button-pushing of any sort not allowed)
2. Adopt “Inattentive driving” citation when distracted behavior but source not ascertainable
3. Strengthen laws (points, on the record)
HOW COULD LEGISLATION BE STRENGTHENED?
CONCLUSIONS
1. Distraction is a growing hazard
2. Strengthening enforcement of distracted driving laws is most effective strategy
3. Distraction risky for the public and for law enforcement
