General information

General overview

Roadworthiness of a vehicle is attested by a roadworthiness certificate. Commercial vehicles within categories N1, N2, N3, M2, M3 must also have a sticker attached to the inside of the windshield on the right side. Trailers within categories O2, O3 and O4 have a sticker attached next to the registration plate. The roadworthiness certificate is an electronic printout of the test results. The date of the expiry is indicated on top of the roadworthiness certificate and also on the sticker with commercial vehicles and trailers. The roadworthiness certificate has two different colors. A green roadworthiness certificate has a normal validity or a validity of 3 months in case of an administrative deficit or when there is a small non-conformity. A red roadworthiness certificate has a limited validity of 15 days when there are technical shortcomings which must be rectified as soon as possible. A red roadworthiness certificate can also mean that the vehicle is prohibited to take part on public roads. In this case “Verboden tot het verkeer” is mentioned on the red form. Used vehicles that change owner must also pass a roadworthiness test and the certificate is valid for 2 months.
