Heavy Vehicles

General

Rates to register a truck, a combination of road vehicles or a farm vehicle are determined on the basis of the number of axles on the vehicle. If this vehicle is part of a combination of road vehicles, however, the number of axles of the trailer (or semi-trailer) it is pulling must be included. For example, a 3-axle truck pulling a trailer with 2 axles will pay the rate that corresponds to 5 axles.

The easiest way to determine the number of axles is to look at the vehicle from the side and count one axle for each tire that is visible. The steering axle must also be included (front wheel), auxiliary lift axle and the axle of a semi-trailer converter dolly (removable axle) must also be included.
