General access heavy vehicles

Under the national mass and loading arrangements, these are vehicles with unrestricted access to the road system, except where a road or bridge is sign posted otherwise. Provided these vehicles have current registration appropriate to the vehicle configuration, no specific access restrictions apply and no additional permits are required.

Prescribed mass and dimension limits

Vehicles which fall within these limits do not exceed prescribed mass and dimension limits, and are therefore general access heavy vehicles.
