Higher mass limits

Transitioned notices covering the operation of heavy vehicle access have been replaced and national and state notices made under the Heavy Vehicle National Law (HVNL) have been updated. A list of expired notices and their replacement is available on the NHVR website.


Operators or drivers of vehicles or combinations operating at Higher Mass Limits in South Australia are required to comply with the updated notice below, available from the NHVR website.

Expiring NoticeUpdated Notice
Higher Mass Limits for Vehicles fitted with Road Friendly SuspensionSouth Australia Class 3 (Application of Higher Mass Limits) Mass Exemption Notice 2019 (No.1)

Note: The updated notice incorporates networks for B-doubles, road trains and modular B-triples that have been brought in from other notices. Since access to Higher Mass Limits (HML) in South Australia does not require participation in the Intelligent Access Program, this notice has been written as a class 3 mass exemption that simply applies HML masses.
