4.11.6Signs for warning of hazardous wildlife#
4.11.6.1Warning signs#
Wildlife warning signs shall be installed when:
- wildlife frequently encroaches onto the road or roadside in localised areas when there is a significant traffic volume, or
- where drivers are unlikely to expect wildlife.
Wildlife warning signs may be repeated (if warranted) at intervals of not less than 5 km in rural areas, or as appropriate in urban areas. It may also be appropriate to sign short, individual lengths of road in specific locations where the risk of an animal / vehicle collision is greatest.
Wildlife warning and information signs are not specifically intended to perform an animal preservation role and research indicates that they are not particularly effective for this purpose. If the preservation of animals is critical other traffic management and animal management treatments will be required; signs alone are not adequate.
Wildlife warning signs should:
- not be provided for migratory animals,
- be continually assessed for their need and relevance, and
- be removed if no longer relevant.
4.11.6.2Temporary warning signs#
Temporary wildlife warning signs (W5-Q18 series) may be used where there have been recent sightings of wildlife, especially koalas and cassowaries, in a localised area.
Examples of temporary wildlife warning signs (W5-Q18)
4.11.6.3High-impact warning signs#
High impact wildlife warning signs consist of a white target board with a green border and incorporate an animal warning sign. Supplementary plates may be installed below where required.
High impact wildlife warnings signs should be used selectively at hotspot locations or in areas with significant conservation value. These signs may be used in conjunction with Wildlife Conservation Area (WCA) signs (see Clause 4.11.6.4) to highlight hotspots within the conservation area.
4.11.6.4Wildlife Conservation Area (WCA) signing#
Wildlife Conservation Area (WCA) signs (W5-Q19) should include the animal symbolic warning sign of the most prevalent animal in the area. WCA signs shall only be installed where the warrants for the included warning sign in accordance with Section 4.11.6 are met.
W5-Q19
WCA signs shall only be installed within the following locations where a 'conservation' status is related to wildlife and not for other reasons (such as scenic value or flora):
- protected areas under the Nature Conservation Act 1992 where vehicle / animal collisions are deemed likely:
- − national parks
- − conservation parks
- − resources reserves
- − nature refuges
- − coordinated conservation areas
- − wilderness areas
- − World Heritage management areas, and
- − international agreement areas.
- land within state forests, timber reserves or dedicated as a reserve (or protected area) for environmental purposes under the Land Act 1994
- a World Heritage Area under the World Heritage Convention
- an area supporting a critically endangered or endangered ecological community in the list established under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act)
- a declared RAMSAR wetland under the EPBC Act
- an area of high nature conservation value under the Vegetation Management Act 1999, or
- an area, other than state-controlled land, identified in a local government's planning scheme as an area that has special environmental significance for native wildlife.
WCA signs should be erected as close as possible to the boundary of the conservation area but shall be placed so as not to compete with other traffic control devices or pose a safety hazard to road users.
WCAs may be marked with the wildlife threshold pavement marking in accordance with Clause 4.11.6.5. Green RRPMs should be used in conjunction with WCA signs (see Clause 4.11.6.6).
4.11.6.5Wildlife threshold pavement marking#
The wildlife threshold pavement marking is detailed in TC2321 and may be used to identify the start of signed WCAs. The wildlife threshold pavement marking should not be used at locations that do not meet the requirements of a WCA (see Clause 4.11.6.4). Wildlife threshold pavement marking should not be used on multi lane arterial roads.
The purpose of the wildlife threshold pavement marking is to complement the entry signs into a WCA and shall bear the words 'WILD LIFE', which shall be marked in accordance with Section 5.8.
Wildlife threshold pavement markings shall meet the skid resistance requirements of Transport and Main Roads' Technical Specification MRTS110 Coloured Surface Treatments and shall consist of a green background with a yellow border.
Green RRPMs shall be installed at all wildlife threshold pavement marking installations (see Clause 4.11.6.6).
4.11.6.6RRPMs#
Green RRPMs may be used at locations with WCA signs (see Clause 4.11.6.4) to highlight areas of greater wildlife significance, or where vehicle / animal collisions are significantly overrepresented. Green RRPMs shall not be installed with wildlife information signs.
Where green RRPMs are used for signing WCAs, they shall:
- a)be installed over the length the WCA
- b)be removed where no longer required
- c)be bi-directional and installed adjacent to the road edge line on both sides of the road
- d)be installed in addition to standard RRPM requirements as specified in Section 5.9
- e)not be installed on motorways
- f)not be installed on roads or in locations where they may pose a hazard to other road users, and
- g)have a minimum spacing of 48 m and not exceed a spacing of 96 m; spacing (m) shall be uniform over the length of the area defined by the WCA.
4.11.6.7Vehicle activated devices#
Vehicle activated devices incorporate a radar device that activates when a vehicle is travelling above a pre-set speed threshold and may be used as an alternative to passive signs. Either flashing lights (wig wags) or the whole sign may be vehicle activated.
These devices may be used where:
- there is an increased risk of animal / vehicle collisions, or
- due to elevated impacts with animals.
Vehicle activated flashing lights#
Vehicle activated flashing lights shall be installed with a radar device capable of detecting vehicle speeds that activate the flashing of the lights in a wig wag arrangement. The devices shall be used with high impact wildlife warning signs (see Clause 4.11.6.3) to enhance sign conspicuity. The flashing lights shall operate alternately when activated by an approaching vehicle which is exceeding a nominated speed within the prescribed times of operation, or during set times when animals are likely to be encountered. The flashing lights shall continue to flash until the vehicle speed reduces to below the nominated speed or the vehicle continues past the sign.
Vehicle activated flashing light signs should be used selectively at critical locations where high impact wildlife warning signs need enhancement to improve driver speed compliance.
Vehicle activated signs#
Vehicle activated signs may be used where the presence of animals along the road is expected and there is a poor compliance with the posted speed. These devices are installed with a radar device capable of detecting vehicle speeds and shall be pre-set with the posted speed limit. A relevant animal symbol that is easily understood by drivers shall be displayed on the sign. When a vehicle is detected, the sign shall activate as follows:
- Vehicle at or below the posted speed limit: device shall activate and cycle between a green symbolic of the animal and the message 'THANK YOU'. Cycle shall be between 1–2 seconds.
- Vehicle above the posted speed limit: device shall activate and cycle between a red symbolic of the animal and the message 'SLOW DOWN'. Cycle shall be between 1-2 seconds.

Replace Item (c) with:
The BUSES MUST ENTER (R6-18) and TRUCKS MUST ENTER (R6-27) signs shall not be used at the entrance to heavy vehicle checking stations (heavy vehicle interception sites).
For guidance on the signing and line marking for heavy vehicle interception sites, refer to the Signing and Line Marking for Heavy Vehicle Interception Sites Guideline.
(e): TRUCKS AND BUSES USE LEFT LANE (R6-28-Q01)
R6-28-Q01
The TRUCKS AND BUSES USE LEFT LANE (R6-28-Q01) shall be used to indicate a mandatory requirement for trucks and buses to use the left lane.
