Costs and payment

The registration fee for a truck, truck tractor or farm vehicle weighing more than 3,000 kg is calculated based on the number of axles on the vehicle and the trailer it pulls.

How to count axles

Look at the vehicle and its trailer from the side. Count one axle for each wheel you see (a double wheel counts as a single wheel).

You must also count the steering axle, auxiliary lift axle and removable axleA supplementary axle or combination of axles that can be added to the axles already attached to a motor vehicle or trailer, or be used to temporarily to convert an object which is not essentially a road vehicle into a road vehicle..

A maximum of 6 axles is counted for calculating the registration fee.

For a truck and a single-wheeled trailer

If the trailer has 2 or more axles, count a single axle if the distance between the centre points of the outermost axles is less than 1 metre.

If the trailer has 3 axles, count only 2 axles if the distance between the centre points of the outermost axles is 1 m or more but less than 2.4 m.

Vehicles for which the axles are not counted

• A tool trailer used only to transport the equipment, tools or furnishings with which it is permanently equipped
• A trailer or semi-trailer with a cargo space less than 4 m long
• A trailer or semi-trailer transporting exclusively a road vehicle authorized to operate mainly on a public road
• A camping trailer (however, the axles on a trailer which requires a special travel permit to operate on a public road [e.g. motor home] must be counted)
• A registered motor vehicle drawn by a tractor vehicle or combination of road vehicles
• A trailer or semi-trailer with a cargo space over 4m long used for personal purposes (by an individual) and for non-commercial purposes
