Heavy vehicles

A vehicle is a 'heavy vehicle' if it has a gross vehicle mass (GVM) or aggregate trailer mass (ATM) of more than 4.5 tonnes.

The Heavy Vehicle National Law (HVNL) and Regulations have commenced in South Australia, Queensland, New South Wales, the Australia Capital Territory and Tasmania, replacing existing state and territory legislation with one heavy vehicle national rulebook.

The HVNL establishes the National Heavy Vehicle Regulator (NHVR) and a single national system of laws for heavy vehicles over 4.5 tonnes GVM and is expected to deliver business and safety benefits to the heavy vehicle industry.

Western Australia and the Northern Territory will not be introducing the HVNL at this point in time and will continue to regulate heavy vehicles under their own state law.

South Australian gazette notices, guidelines, exemptions and policies made under state legislation have been transitioned under the HVNL. The NHVR has not remade these notices, instead they continue to exist in their current state under the HVNL. All transitional notices are intended to be remade into either a state HVNL notice or a national notice, prior to their expiry. 

Please note that from Thursday 27 February 2014, there will be changes to SA heavy vehicle permit arrangements. To learn more, visit Permits for oversize and overmass heavy vehicles.
