Heavy vehicle permits
Application process for trips within South Australia
The Department of Planning, Transport and Infrastructure (DPTI) processes applications for Class 1 oversize/overmass, agricultural vehicles and special purpose vehicles (eg mobile crane, concrete pump, drill rig or fire truck) on behalf of the National Heavy Vehicle Regulator (NHVR).
The NHVR processes all Class 2 and Class 3 heavy vehicle permit applications for travel in South Australia. To apply for a Class 2 or 3 permit, you will need to lodge your application via the NHVR Portal.
For all cross-border applications you should continue to apply to the NHVR through their Access Management website.
