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 and Overmass (OSOM) Vehicle Arrangements—first recommendations identified for implementation

On 6 April 2019 the Deputy Prime Minister and Minister for Infrastructure, Transport and Regional Development, the Hon Michael McCormack MP announced state and territory transport Ministers agreed for 12 of the recommendations from the OSOM Review to be implemented.

These 12 recommendations have been prioritised for short-term implementation, with the agreed implementation approach and status listed in the following table.

Rec No.

Lead agency


Agreed approach

Completed. New policy issued by the NHVR in August 2019.



Council agree to consistent permit durations for period permit to 12 months.

States to make system/process changes to allow 12 month period permit.

All permits have an automatic empty return trip attached as a condition of permit, which do not require a new assessment.

NHVR and relevant jurisdictions implement system change to allow applicant to register return trip (separate permit assessment not required).




This Review recommends NHVR maintains a feature list for improvements to the NHVR Portal and prioritises and implements features in a timely manner. This review recommends the feature list include the following:

    1. Introducing business rules on the application page to capture mistakes or out of range values.
    2. Preload information capability, including:
      1. Vehicle configurations and details.
      2. Previously applied for permits with routes and configurations.
      3. Transport operator details.
      4. Reference previous applications with similar routes or configurations.
      5. Link permits – including project specific movement with multiple movements of the same type or route.
    3. Flexibility to:
      1. Make minor changes or amendments to the application without rejection resubmitting a new application.

List multiple prime movers or trailers on permits to allow flexibility.

NHVR to action.

In progress. The NHVR is continually improving the portal.



Council agree a project team be set up within NHVR to investigate possible technology solutions for the better management of movement data.

NHVR to action — within 3 months.




NHVR to replicate the Local Government Association of Queensland model for funding Heavy Vehicle Access Liaison Officers, to work with Local Government to deliver proactive approaches for OSOM access

NHVR to action within 12 months.

In progress. The South Australian Department of Planning, Transport and Infrastructure (DPTI) is working with the Local Government Association of South Australia and the NHVR to progress this recommendation. The NHVR is progressing discussions with other agencies.



NHVR to work with road managers to identify pinch points in their network, NHVR to consolidate this information into their Portal and Mapping tools.

NHVR to action within 12 months.

In progress. The NHVR is continually updating the functionality of its route planner. In addition, the 2019-20 Budget allocated $8.0 million over two years to the NHVR to fund engineering assessments for local government owned road network infrastructure, and to build an asset collection database.



Council agree the following recommendations be included into the National Transport Commission’s (NTC) Review of the Heavy Vehicle National Law (HVNL):

    1. Section 156 of the HVNL is reviewed, with prescribed time limits more appropriately structured.
    2. Review and harmonise the definition of ‘indivisible’, to deliver consistency across jurisdictions.
    3. Section 661 of the HVNL be reviewed and changed to provide a trigger clause for the NHVR to manage when there is no response from Road Managers for consent.
    4. Section 158 of the HVNL is reviewed to appropriately recognise third parties and make improvements to streamline the consenting process.

NTC to incorporate recommendations into Review of the Heavy Vehicle National Law.




Council agree that all relevant policy and regulatory agencies commit to identifying and highlighting best practice, to deliver 48‑hour (on average) OSOM turnaround time by 2021.

Completed, agreement obtained.

Review of Oversize and Overmass (OSOM) Vehicle Arrangements—second tranche of recommendations identified for implementation

On 2 August 2019, the Transport and Industry Council (the Council) agreed to an additional tranche of OSOM recommendations for implementation. The OSOM Working Group will now progress these recommendations.

If you would like to put forward any views on the implementation of these recommendations, or on other recommendations that should be prioritised, please send an email to osomreview@infrastructure.gov.au

Rec No.

Review of Oversize Overmass Vehicle Access Arrangements

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.

The Terms of Reference DOCX: 20 KB PDF: 341 KB ReadSpeaker set out the scope of the review.

On 9 November 2018, the Transport and Infrastructure Council agreed to the release of the independent Review of Oversize Overmass Vehicle 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.

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

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.
