The MUTCD outlines the design and application arrangements for traffic signs, signals and markings installed on a road. It has many different parts, specifying how different areas such as bike lanes, railway crossings, transit lanes, main routes and roadwork zones should be signposted. All the various parts of the Australian Standard 1742 are noted at the end of this article.

Road signs are classified with alphanumeric codes, each indicating different types of use. The top level of categories are:

Hazardmarkersigns meaning

Queensland uses a similar numbering system. Temporary road signs for QLD are often a different size or shape to NSW as QLDTMR utilises multi-message signs. These consist of a frame that holds 3 different signs, enabling traffic controllers to customise messages for each project.

Multi message signs are also used on Victorian roads. The extensive VicRoads signage document specifies all the different signs used on the state’s roads.

Queensland uses the MUTCD guidelines but also has its own ‘Q-Series’ signs specifically for this state. All the TC (traffic control) and Q Series signs (Queensland specific) can be found online in the TMR register.

Victorian special signs are denoted with a V prefix before the group number (e.g. R7-V100). Victorian signs are organised under the following categories, similar to NSW & QLD:

Most states have their own categorisation system that works within the Austroads Guide to Traffic Management and the Manual of Uniform Traffic Control Devices (MUTCD – also known as the Australian Standard).

Where signs are available in either aluminium or corflute construction, Jaybro adds the AL (aluminium) or CF (corflute) suffix to the end of the code.
