General information

General overview

If a vehicle passes the roadworthiness test, the approval of roadworthiness is registered electronically and is available online and in the register of the Norwegian Public Roads Administration. A paper receipt for the inspection is also delivered to the owner of the vehicle. This contains no security elements. If there is a need for a follow-up inspection, the document is a reminder that a new roadworthiness test must be carried out. The deadline for inspection is calculated from date of the last main inspection. If a follow-up inspection is needed, the inspection deadline will still be calculated from date of the main inspection. Vehicle owners may carry out the inspection up to two months before the inspection deadline.

Major changes

As of 08/02/2019, there is a new system for roadworthiness inspection in Norway. Previously, the deadline for inspection was guided by the last digit of license plate. Now the deadline is calculated from the date of the last complete inspection.
