Tow trucks are not exempt from statutory mass and dimension requirements. If a tow truck exceeds a statutory mass or dimension limit, they must operate in accordance with an appropriate permit.

The Guidelines for Tow Truck Licensing and Permit Requirements (PDF) outlines the permits that are appropriate for tow trucks under different scenarios and the types of authorisations that Main Roads will issue. After-hours permits and authorisations will be issued by Main Roads in accordance with the HVS After-hours Procedure for Tow Truck Approvals (PDF).

The available Heavy Lift Tow Truck Over Mass Period Permits provide extra mass limits on tandem and tri drive axle groups for an approved tow truck, when towing a vehicle on a public road in WA.

Prior to applying for a permit, you must have your tow truck inspected and approved by the Department of Transport.

To arrange to have your tow truck inspected, please contact the Department of Transport Vehicle Safety Policy Section via email: vsp@transport.wa.gov.au

Once you have obtained approval from the Department of Transport, you must provide this with your permit application.
