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.

Please note the National Heavy Vehicle Regulator (NHVR) has published a revised Notice in 2022 for vehicles and combinations operating at HML masses; refer below:

Expiring NoticeUpdated Notice
South Australia Class 3 (Application of Higher Mass Limits) Mass Exemption Notice 2019 (No.1)South Australian Class 3 Road Friendly Suspension Mass Exemption Notice

Note: The 2019 Notice incorporated networks for B-doubles, road trains and modular B-triples that were combined from other notices into one. The current Notice removes references to Schedule 5 of the Heavy Vehicle (Mass Dimension and Loading) National Regulation.

Note: eligible vehicles are still granted access on South Australian Higher Mass Limits networks; the Road Friendly Suspension Notice functions identically to the Notice it replaces.
