B-double permit

Do I need a B-double permit?

A B-double permit is required for travel on a road outside of the approved B-double network. Operators should check if their requested route is on an approved B-double route, as they may be able to operate under a gazette notice instead of needing a permit.

The NHVR processes ALL B-double 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.

In the process of seeking consent from the road manager, the NHVR will request the road manager to consider the route to be included as a route approved under the gazette notice.

If you are operating a B-double that does not meet the prescribed mass or dimension limits within the National Class 2 B-double Authorisation Notice 2019 (No.1), you may need to submit a Class 3 (Miscellaneous) permit application if the requested journey is not on an approved class 3 route.

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.
