The Austroads Board undertook a project to refine traffic management at road works, by developing and simplifying guidance documents, and improving training and consistency across Australia. The project aimed to standardise the approach to temporary traffic management across Australia and in New Zealand.

The project resulted in the release of the Austroads Guide to Temporary Traffic Management in December 2019 and an update of the current Australian Standard 1742.3 – Manual of uniform traffic control devices, Part 3: Traffic control for works on roads, which was launched on 11 December 2019.

The updated standard set out to improve the ability of road agencies, contractors, traffic management practitioners and industry to meet their Work Health and Safety (WH&S) requirements, and achieve better safety outcomes at road works sites.

The Department as a Participating Agency and the State Road Authority was heavily involved in consultation and implementation of the project within Tasmania.

For information on the project, please go to the Austroads website.


The Austroads Guide to Temporary Traffic Management (the AGTTM) was released in December 2019, detailing contemporary traffic management practice for application at road work sites across Australia and New Zealand.

The AGTTM was adopted in Tasmania on 1 January 2021 and can be found at

In addition to implementation of the AGTTM, organisations must comply with:

3Road categories

The Austroads Guide to Temporary Traffic Management: Part 8, Section 2 details a road categorisation system for the purpose of applying temporary traffic management practices.

These categories determine a number of requirements under the guide including temporary traffic management design practices and training.

The Department of State Growth (the Department) has worked with all Tasmanian Councils to collect road category information for Local Government roads. This information has been collated for industry use.

Most roads on the Tasmanian road network fall under the Category 1 criteria.

Although the classification of road categories has been outlined in the link below, the development of traffic management plans and traffic guidance schemes should be subject to a risk assessment, relevant to the conditions of the site, and any clarification can be sought from the Department, or the relevant Local Government area.

A list of Tasmanian state and local roads that fall outside the Category 1 criteria can be accessed by clicking on the link below.
