Published: 14/07/2021

It is a regulatory requirement that marking plates be placed on the rear of certain motor vehicles and trailers in order to improve their visibility and to provide the do not overtake turning vehicle warning to other motorists.

This bulletin identifies the types of plates that can be used, where they are placed on the vehicle and the methods for installing them.

Class 400, Class 1A, UNECE R70 and Class 2 rear marking plates.

Although rear marking plates installed on heavy vehicles and trailers must be retroreflective, i.e. made of a material that reflects an incident light beam directly back to its source, they cannot be used in place of other reflectors required by Australian Design Rules (ADRs) or vehicle safety standards.
