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 o o o inspections kerbside collections road marking 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).
D1 General TMA roll ahead distance (protecting workers on foot) 10m roll-ahead distance required in front of shadow vehicle with TMA Working Space 10m roll-ahead distance Truck with TMA Shadow vehicle TMA
D1 General Visibility - Clear sight distance Clear sight distance 3 x permanent speed limit All roads, with the exception below Exception: 75m Level 1 non state highway roads with permanent speed limit less than 55km/h RCAs may designate a greater CSD for these roads.
D2 Work vehicles Forward visibility is greater than clear sight distance TV2 On level LV and level 1 roads, the work vehicle must have rear visibility of 50m TV4 RD6R Work vehicle Rear visibility If a shadow vehicle is used then this distance applies to the rear of the shadow vehicle 5 to 20 seconds travel time (approx. 100-600m) Tail pilot Rear visibility is greater than clear sight distance T1A/T134 RD6R
D2 Work vehicles Mobile operations rotating role of vehicles on level 2 and 3 roads Contractors are expected to use: o o o AWVMS or pilot vehicle(s) to provide advance warning shadow vehicles fitted with TMAs, and 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 o o advance warning, and direction and protection signs, including approved TSL sign(s) installed 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.
D3 Pilot vehicles Lead and tail pilot vehicles Maximum distance from pilot vehicle to next vehicle is between 5 and 20 seconds normal travel time Previously was 5 10 seconds Approximately 100m to 600m at 100km/h Between 5 and 20 seconds (approx. 100m to 600m) Tail pilot Shadow vehicle
D4 Shadow vehicle Vehicle position Distance between work and shadow vehicle Work vehicle 1m lateral safety zone * Under 65km/h Over 65km/h 25m to 40m 40m to 60m 10m roll ahead distance Shadow vehicle
Rear visibility required for a shadow vehicle The rear visibility required for a shadow vehicle is at least: o o 50m on level LV and level 1 roads, if a shadow vehicle is not used then this distance applies to the rear of the work vehicle, and 100m on level 2 and level 3 roads

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
