Heavy Vehicle Regulation

On 10 February 2014, the Heavy Vehicle National Law, covering all heavy vehicles over 4.5 tonnes, commenced in Queensland, New South Wales, Victoria, Tasmania, South Australia and the Australian Capital Territory (ACT). The law covers matters relating to vehicle standards, mass dimensions and loadings, fatigue management, the Intelligent Access Program, heavy vehicle accreditation and on-road enforcement. The ACT has partially implemented the legislation and will proclaim remaining elements of the legislation at a later date. Western Australia and the Northern Territory are not participating in the national reform at this time.

The law is administered by the Brisbane‑based National Heavy Vehicle Regulator. The Regulator, in conjunction with the National Transport Commission, continues to progress national heavy vehicle reforms through its forward work program.

Review of Oversize Overmass Arrangements

On 9 November 2018, the Transport and Infrastructure Council agreed to the release of the independent Review of Oversize Overmass Access Arrangements Report PDF: 4114 KB ReadSpeaker. There are 38 recommendations in the Report covering a wide range of OSOM issues. The extensive number of recommendations reflect the complexity of OSOM vehicle access, the considerable stakeholder engagement (with over 60 separate entities engaged during the preparation of the Report), and the need for a comprehensive suite of solutions to improve the system.

Governments, including local governments, are now considering the Report and recommendations to identify where early actions can be taken. As OSOM access arrangements can be complex and differ across Australia, consideration must also be given to ensuring the recommendations are implemented appropriately, taking into account any specific state or territory requirements.

The Department will commence initial industry consultation in coming weeks to assist prioritisation of actions.

The Report has been published without appendices as they contain sensitive and commercial‑in‑confidence material.


The Deputy Prime Minister and Minister for Infrastructure, Transport and Regional Development, the Hon Michael McCormack MP, announced on 29 July 2018 the Australian Government would fund an independent review. Consultancy firm, WSP Australia, undertook the review and were assisted by a three‑member industry expert reference group.

History of Heavy Vehicle Regulatory Reform

In July 2009 the Council of Australian Governments (COAG) agreed that a single national heavy vehicle regulatory regime be established to cover all vehicles over 4.5 gross tonnes. COAG agreed that the national regime include a single national regulator to administer a single set of national heavy vehicle laws replacing the separate and at times conflicting regulatory requirements on the heavy vehicle industry between states and territories.

In August 2011 an Intergovernmental Agreement on Heavy Vehicle Regulatory Reform was signed by COAG (except Western Australia) setting out the principles and processes to implement the decision to deliver a national heavy vehicle regulatory system. The signing of this agreement recognises that the Commonwealth and the states and territories have a mutual interest in improving national regulation and the need to work together to achieve these outcomes.

In November 2011 the Heavy Vehicle National Law Act 2012 was approved by the Ministerial Council on Transport and Infrastructure and was passed by the Queensland Parliament in August 2012.
