Increased mass limits for ADR 80/04 heavy vehicles.
The Heavy Vehicle National Law (HVNL) provides for three classes of heavy vehicle as a means of managing the different access requirements of different types of heavy vehicles.
Concessional Mass Limits (CML) allow an operator to operate at mass limits above the national general limits provided they are accredited under the National Heavy Vehicle Accreditation Scheme (NHVAS).
General Access Vehicles (GAV) comply with mass and dimension requirements and do not require a notice or permit to operate on the road network.
General mass and dimension limits are based on the limits set out in the Heavy Vehicle (Mass, Dimension and Loading) National Regulation.
Higher Mass Limits (HML) allow particular heavy vehicles to access additional mass entitlements under certain conditions.
An increase to the overall width limit to 2.55 metres is available for trucks fitted with a number of specific safety features.
