Heavy vehicle guidelines and class permits

On 10 February 2014 the Heavy Vehicle National Law 2012 (HVNL) commenced, replacing existing laws governing the operation of all vehicles over 4.5 tonnes gross vehicle mass in Queensland, New South Wales, Victoria, South Australia, the Australian Capital Territory and Tasmania.

The National Heavy Vehicle Regulator (NHVR) was established to administer the HVNL. The NHVR is now the first point of contact for the majority of your heavy vehicle business.

Prior to the establishment of the NHVR the Department of Transport and Main Roads, in cooperation with other agencies, local government and industry, developed numerous guidelines and policies to facilitate the movement of large vehicles and vehicles carrying large indivisible articles within Queensland in a safe and efficient manner. These guidelines and policies provide a balance between the needs of industry and the impact of heavy vehicles on the road network and the community.

Guidelines provide an exemption from regulations and are considered a legal authority. These guidelines enable access to the road network, in some cases, without the need for obtaining individual permits.

Existing provisions (guidelines etc) are preserved under the HVNL, unless they are replaced by a NHVR document (e.g. notice or regulation) or expire.

A detailed reference of various combinations and their axle masses are indicated in the axle mass limits in Queensland comparison table. These masses are a guide only and may change. They are to be used as a reference only and should not be taken to override the legislation.

It is not a requirement in Queensland to carry a guideline in the vehicle. Operators should, however, be fully aware of all the conditions and restrictions that apply when considering operating under the legal authority of a guideline.
