Special purpose vehicle requirements

A special purpose vehicle (SPV) is a vehicle built for a purpose other than carrying goods such as a mobile crane, a concrete pump or drill rig. An SPV exceeds one or more of the general mass and dimension limits set out in the Heavy Vehicle (Mass, Dimension and Loading) National Regulation, and is a Class 1 heavy vehicle.

Check permit requirements and find out what heavy vehicle network routes apply.
