For a new and/or improved device to be considered for use on State roads, applicants must follow the following process:

  • Submit requests for assessment of a new or improved device via email to the State Roads Work Health and Safety (WHS) mailbox:
  • Provide as much information as possible to support the application, such as:
    • evidence of approval from other jurisdictions
    • photos/videos of the device
    • results from previous tests or trials
    • Any other evidence to demonstrate the use and safety of the device.

Devices covered under AS 1742.3 and the Austroads Guide to Temporary Traffic Management (AGTTM) do not have to be assessed through this process.

Approval of a device does not negate the need for relevant permits or approvals to be obtained for activities on the road network. For works on State Roads, refer to the Transport website for links to permit and approval types. Local Councils and other road authorities will have separate permit and approval processes.

2Assessment process

  • TIG Temporary Traffic Management Working Group (TIG TTMWG) receives application
  • TIG TTMWG undertakes the preliminary assessment and conducts any necessary research
    • Conditional approval may be applied for a trial of devices
  • The Department will notify industry of approved or withdrawn devices via the State Roads Austroads Guide to Temporary Traffic Management (AGTTM) mailing list

The original scope of the Austroads Guide to Temporary Traffic Management included a dedicated part of the Guide for device approval. A national working group was also included in the scope to assess and approve temporary traffic management devices, which would then be adopted in Tasmania.

Due to the difficulty of a national approach and other considerations, the Austroads project team removed this part of the Guide before its release in December 2019. Each jurisdiction is now responsible for assessing and approving the use of temporary traffic management devices.

Austroads will develop a national assessment scheme for traffic control devices to integrate this practice. This will also reduce the burden associated with individual jurisdictional assessments. Once this scheme has been developed and implemented, Tasmania will join this national scheme.
