Apply for a Higher Mass Limits (HML) vehicle access permit

If you want to drive a Higher Mass Limits (HML) vehicle outside the approved HML road network, you'll need to apply for an access permit through the National Heavy Vehicle Regulator (NHVR). 

The NHVR permit applies to travel throughout Australia, with the exception of Western Australia and the Northern Territory, where you'll need to apply directly to the relevant state or territory road transport authority. 

For the most up-to-date information on how to apply for a Higher Mass Limits (HML) vehicle access permit, visit the NHVR website.

Note: If you're operating a Performance-Based Standards vehicle at HML, you'll need to apply for a Performance-Based Standards (PBS) access permit.
