The tolls you pay depend on your vehicle’s class and the toll road you use. In NSW, vehicles fall into two classes, class A or class B.

A vehicle class is determined by the total size (length and height) of your vehicle.

Vehicle dimensions include any items you place on your roof or tow behind your vehicle, such as a caravan, trailer or boat.
