Proof of conformity of a motor vehicle

Anyone who buys a new or used vehicle (in Luxembourg or another country), or who wishes to import their vehicle when relocating to Luxembourg, must be able to provide proof of its conformity for the purpose of registration.

To do so, the owner/holder of the vehicle must possess the following documents:

  • a European certificate of conformity;
  • a photograph of the manufacturer's plate;
  • a conformity sticker (for vehicles not subject to roadworthiness inspections).

European certificate of conformity

The certificate of conformity—also known as a community certificate of conformity, or COC—is a document issued by the manufacturer when the vehicle is first sold, attesting that the vehicle is in conformity with European Union motor-vehicle approval and road traffic directives.

The European certificate of conformity is one of the documents that must be kept on board vehicles registered for the first time on or after 1 February 2016.

Photograph of the manufacturer's plate

When a vehicle does not need to be presented to the SNCA for registration, a photograph of the vehicle manufacturer's plate must be provided with the administrative file if the vehicle was registered for the first time on or after 1 February 2016. The vehicle must be neither modified nor converted, and must be covered by a full European certificate of conformity with no inconsistencies.

The location of the manufacturer's plate is specified in the European certificate of conformity. The photograph must be clear and legible and may be printed out on paper.

Conformity sticker (for vehicles not subject to roadworthiness inspections).

When the vehicle to be registered is not required to undergo periodic roadworthiness inspections, it must be covered by a valid conformity sticker.

The conformity sticker should be obtained from the SNCA if the vehicle is in conformity with a vehicle type that has been approved under the Grand-Ducal regulation of 26 January 2016 relating to approval and registration of road vehicles.

The sticker must be affixed to the vehicle so that it is visible and legible at all times.

The following road vehicles are not subject to periodic roadworthiness inspections:

  • motor vehicles with a maximum design speed that does not exceed 25 km/hr;
  • trailers not intended for the transportation of people and whose maximum authorised mass does not exceed 750 kg;
  • mopeds and lighteight quadricycles;
  • mobile tractors and machines whose maximum design speed does not exceed 40 km/hr, whose unladen mass in running order exceeds 600 kg and which are not intended to exceed 25 km/hr when towing one or more vehicles;
  • vintage vehicles registered for the first time prior to 1 January 1950.
