A5.8.5 Responsibilities of STMS on level 2 & 3 roads
When the level 2/3 STMS must be onsite The STMS must be present at an attended worksite at
all times except during a drive through when the STMS may need to leave the worksite to gain access to the front of the worksite.
In this case the STMS may be away from the worksite for up to 30 minutes.
A5.8.5 Responsibilities of STMS on level 2 & 3 roads
Exceptions to this rule are as follows: An STMS is permitted to control up to four attended
shoulder closure worksites on level 2 and level 3 roads at any one time subject to the following: o an STMS remains within 30 minutes of all worksites o a person with a minimum qualification of STMS-NP is present
and takes charge of TTM at each attended worksite o that STMS-NP must have been briefed by the STMS and the
briefing documented o the STMS must be present for the set up, alteration and
removal for each of the worksites.
A5.8.5 Responsibilities of STMS on level 2 & 3 roads
Mobile operations on level 2 roads On level 2 roads where all activity is at least two metres
clear of the edgeline, an STMS-NP may take the role of an STMS and set up, maintain, alter and remove TTM under the following conditions: o the STMS must brief the STMS-NP in charge of the operation
on the TTM requirements o all the above actions must be documented by the STMS.
A5.9 Traffic controller
TC responsibilities now listed separately Extract from CoPTTM
A6.4 Certification and registration
Updated training process and clarified ROPE for Level 2/3 STMS
Requalification via a ROPE is a privilege - not a right
ROPE •This form must contain the details of six closures completed while the practicing STMS held their qualification. •The six closures must be carried out in the nine months preceding submission of the ROPE application
Non-conformance Applicants who have received a non-conformance, or who have an unsatisfactory report may not be considered for ROPE. However if a non-conformance report is followed by a 12 month period of satisfactory performance the ROPE may still be allowed

Section
D1 General
Mobile closure A normally continuously moving activity or work
operation carried out within the road reserve that may also stop briefly at a particular location for a period of no more than 10 minutes. Note: Activities like mole ploughing and drain digging move along the road but they move too slowly to be considered mobile operations. These types of activities must be planned and managed as static operations.
D1 General
Semi-static closure A short term activity or work operation that is carried
out on the carriageway of a road at a particular location that takes more than 10 minutes, and less than 1 hour, to complete. Note: The 10 minutes to 1 hour timeframe applies only to the working period and does not include the time required to install and remove the TTM devices on the worksite. No work is to be undertaken during set-up or removal of TTM equipment.
D1 General
Special operations These are mobile operations which may vary the
requirements of the above two categories or provide additional requirements to enhance safety for certain situations
Included in this category are: o inspections o kerbside collections o road marking o rolling blocks.
D1 General
TV2 (TW-26) road works sign
If lead pilot vehicle not required, the TV2 (TW-26) sign is only required on the lead working vehicle where the speed limit is greater than 65km/h
Signs on cars or light utility vehicles Where cars or light utilities are used (for inspections, sports
events and high speed data capture) only the appropriate supplementary sign will be required
Signs on work vehicle more than 5m from edgeline
Where the work vehicle is more than 5m from the edgeline the work vehicle must have either:
the appropriate advance
warning sign with supplementary plate if required and the RD6R (RG-34) sign
or the TV4 (TW-34) PASS WITH
CARE sign and the RD6R (RG-34) sign.
D1 General
When RD6L/R (RG-17/34) signs can be omitted from the TV4 (TW-34) Pass with Care sign Where the situation is constantly changing (eg rolling,
grading, road marking, water cart, drag brooming operations on two lane one way roads) and it is impractical to change the RD6L/R arrow frequently, it may be omitted
D1 General
LAS operation now included in this section Caution mode lane closed
A part of the roadway which is used for driving is closed and it is unsafe to pass.
Note: Downward or upward pointing arrows are currently not gazetted signs and MUST NOT be used
Downward or upward pointing arrows must not be visible when TMA is not engaged in traffic management
D1 General
Use of AWVMS added to this section The AWVMS replaces the need for a tail
pilot TMA vehicle
Using an AWVMS is optional for most RCAs. However on level 2 and 3 state highways their use is mandatory (from 1 July 2012).
The maximum allowable separation from an AWVMS to a shadow vehicle TMA is 1600m (this distance may be extended from 1600m to 3km if there is no available shoulder width for the AWVMS within 1600m of the next working vehicle).

Mobile operations – rotating role of vehicles on level 2 and 3 roads Contractors are expected to use:
o AWVMS or pilot vehicle(s) to provide advance warning o shadow vehicles fitted with TMAs, and o work vehicles
The roles of the vehicles may be rotated if the work vehicle is a TMA truck
No workers are allowed on the back of the AWVMS, pilot and/or shadow vehicles
The full complement of vehicles must be maintained
Operating mobile operations within an established static worksite
Where a mobile operation is contained completely within an existing fixed static worksite which has: o advance warning, and o direction and protection signs, including approved TSL sign(s)
installed o CSD available to the work vehicle at all times
the requirement for a tail pilot vehicle for any mobile operation within the worksite is waived.
All other requirements for mobile operations with respect to shadow and work vehicles must still be applied.

Cone tapers when an AWVMS is used
(Amendment to D6.1.2 Worksite layout and D6.1.3.4) Where an AWVMS is used as the advance warning
and direction and protection sign for the semi-static closure there is no requirement to place a cone taper to the rear of the shadow vehicle.
Amendments have been made to the following TMDs: o G2.14 o H3.1 o H3.2.
D7 Special activities
Road marking – covered in section D and industry best practice TMPs are available in section I
Kerbside collections - covered in section D and industry best practice TMPs are available in section I
Requirements for repairing a flexible median barrier have been added to section D
Requirements for rolling blocks have been added to section D
D7 Special activities - Inspections
Inspections and non-invasive works Includes:
o observation, using a measuring wheel, surveys, traffic counts, o installing traffic count equipment, o road maintenance activities such as removal of litter, cleaning
signs, cleaning edge markers, installing edge marker posts, temporary pothole repairs, hand clearing vegetation from culvert headwalls and inlet /outlets or taking photographs.
More complex activities, or those which cannot immediately move off the live lane, require mobile or static TTM
Type of road On Shoulder – no time limit
On live lane up to 5 minutes
On live lane for more than 5 minutes
Level LV One person activity. STMS or TC qualified inspector working under a TMP prepared by a STMS – Inspector must be briefed by a STMS. STMS or TC must be on site at all times. Level 1
Two person activity. STMS or TC qualified inspector working under a TMP prepared by a STMS – Inspector must be briefed by a STMS. STMS or TC plus lookout/spotter must be on-site at all times.
Level 2 & 3 STMS – NP on site and in control of activity at all times.
Mobile, semi-static closure or static fixed site closure required.
D7 Special activities
General rules
Inspectors must move to avoid traffic. They must not expect traffic to move or slow down to avoid them
On busy roads avoid peak periods or use a higher level of TTM
Crossing a level LV, 1 or 2 road does not constitute being on a Live Lane
Crossing a level 3 road does, unless a pedestrian crossing facility is being used
D7 Special activities
Vehicle
Advance warning (inspection vehicle fitted with one and preferable two amber flashing beacons and a rear mounted sign indicating the type of activity taking place) must be positioned in advance of the inspection site
A vehicle is not required on a level 1 road with a permanent speed of less than 65km/h
An amber flashing beacon is not required on an unsealed shoulder (including footpath) of a road with a permanent speed of less than 65km/h
D7 Special activities
Spotter
A spotter is not required on LV roads
Where no LV roads have been designated, the RCA can select level 1 roads for ‘single inspector’ inspections
Where an unaccompanied inspector is not able to maintain adequate attention (for example, due to work tasks, or poor visibility), a spotter will be required or another type of traffic management operation used
