Higher Mass Limits permit

Do I need a Higher Mass Limits permit?

A Higher Mass Limits (HML) permit is required for travel on a road outside of the approved HML network. Visit Higher Mass Limits for more information about HML.

Operators should check if their requested route is on an approved HML route, as they may be able to operate under a gazette notice. If any part of your journey is not on an approved HML route, you will need to apply for a HML permit.

The NHVR processes ALL HML permit applications for travel within and between the Australian Capital Territory, New South Wales, Queensland, South Australia, Tasmania and Victoria through the NHVR Portal.

For travel within the Northern Territory and Western Australia you need to apply directly to the relevant state or territory road transport authority.

Note: HML access in New South Wales is only available by obtaining a HML permit from the NHVR.

If you are operating a Performance-Based Standards vehicle at HML, you will need to submit a Performance-Based Standards vehicle permit application.

Note: Operators should check that their vehicle complies with the schedules and conditions in the relevant gazette notice as the permit relevant to this application will reference these same conditions.
