GAV - Common Rigid Trucks

General Access Vehicles (GAV) don't require a permit or notice to access road networks; these vehicles have as-of-right access to the network unless otherwise signposted. For a heavy vehicle to be considered a GAV, they must be within the size and weight range outlined below.

The following 2, 3 and 4 axle rigid trucks and 4 and 5 axle twinsteer rigid trucks are General Access Vehicles (GAVs) when complying with GML, CML and the general dimensions described below.

Description Image Max Length

Max Mass under CML
(tonnes)
2 Axle Rigid Truck General Access Vehicle - 2 Axle Rigid Truck < 12.5 15.0 CML does not apply to single axles
3 Axle Rigid Truck General Access Vehicle - 3 Axle Rigid Truck < 12.5 22.5 23.0
4 Axle Rigid Truck General Access Vehicle - 4 Axle Rigid Truck < 12.5 26.0 27.0

In the above examples, a complying steer axle is permitted up to 6.5 tonnes on the steer axle provided it does not exceed the manufacturers rating. The allowable GVM may then also be increased by up to 0.5 tonnes.

4 Axle Twinsteer Rigid Truck General Access Vehicle - 4 Axle Twinsteer Rigid < 12.5 26.5 27.0
5 Axle Twinsteer Rigid Truck General Access Vehicle - 5 Axle Twinsteer Rigid < 12.5 30.0 31.0

In the above examples, a twinsteer heavy vehicle fitted a with load-sharing suspension system is permitted up to 11 tonnes on the steer axle, provided it does not exceed the manufacturers rating. The allowable GVM may then also be increased by up to 1 tonne.

 

Note: Combinations operating at Higher Mass Limits (HML) are considered a Restricted Access Vehicle (RAV) and must comply with the relevant state notice or permit conditions.
