Exemption permit for a change to the structure of a vehicle or trailer

You may apply for an exemption from the requirements for modifying the structure of a vehicle or trailer if you have a special reason to make a change that is on a larger scale than is normally permitted. A requirement for granting the exemption is that it would only minimally increase the risk to safety, health or the environment and not distort competition.

It is possible to modify a vehicle’s structure without an exemption permit when the alterations are carried out in accordance with the applicable regulations. All changes should primarily be made within the framework of the structural modification regulations.
