National heavy vehicle mass and dimension limits

The Heavy Vehicle National Law (HVNL) provides General Mass Limits (GML), Concessional Mass Limits (CML) and Higher Mass Limits (HML) for heavy vehicles operating on the national road network. This fact sheet summarises the conditions for operating general access and restricted access vehicles, relating to axle mass and configurations. High productivity vehicles, such as B-doubles and HML vehicles are important to the efficiency of the freight task in Australia. The larger capacity of these vehicles also reduces the number of vehicles required to transport a given amount of freight.
