GAV - Common Rigid Trucks

GAV - Rigid VehicleGeneral 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, it must be within the size and weight range outlined below.

rigid truck has its cargo carrying space affixed to the cab of the heavy vehicle. 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. Images in the table show the maximum applicable mass with the minimum required axle spacing. A rigid can operate at lesser mass limits with a smaller axle spacing; for more details, refer to the general axle spacing mass limit.

All rigid trucks must be within these dimensions:

  • Width: 2.5M
  • Height: 4.3M
  • Length: 12.5M
  • Rear Overhang: 3.7m or 60% of the wheelbase (whichever is lesser)

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.

Axle spacing

The spacing between axle groups determines the maximum allowable mass over those axle groups.

Figure 1 shows an example of the axle spacing requirements and mass limits for a rigid truck and dog trailer. There are six checks which all must comply with axle spacings mass limits general table. The spacing between axle groups determines the maximum allowable mass over those axle groups.

Complying steer vehicle is otherwise known as FUPS

Allowable steer axle mass increase on all Heavy Vehicles greater than 15tonnes.Compliant vehicles may operate with up to an additional 0.5tonnes on the front steer axle (single only). The allowable GVM or GCM can be increased by the additional mass carried on the front steer only.

Where no additional mass is carried on the front steer axle, no GVM or GCM increase is allowed.

FUPS is conditional on the manufacture's ratings for the axles, GVM & GCM

GML

The heavy vehicle general axle mass limits prescribed in the HVNL that apply to public roads in Australia unless otherwise limited by load restriction signs. 

Total combination mass

The maximum allowable mass limit for a heavy or combination.
