Signposted limits
There are different types of signposted limits under the Australian Road Rules which drivers must obey, including ones relevant to mass such as:
- load limit signs
- no truck signs.
Signposted limits restrict all vehicles to the limits imposed by the sign and are not overridden by mass exemptions.
The mass limit of a vehicle is the lesser of the manufacturer's mass limits, general mass limits or other mass limits such as those imposed by a sign for a bridge or road.
