Transformations and alterations to a vehicle that result in changes in its technical characteristics must be checked and/or accepted at the SNCA, and the registrations certificate may need to be amended before the vehicle can be put on the road.
Technical alterations include (non exhaustive list):
- alteration to motorcycle engine;
- alterations to the external fittings of a vehicle (exhaust pipe, bodywork, spoilers, wheel spacers, etc.);
- alterations inside a vehicle (fitting-out as ambulance, driving school car, hearse, etc.);
- alterations to the suspensions;
- fitting different tyres and wheels (if the combination is not listed on the European Certificate of Conformity);
- altering the vehicle to use a different fuel (e.g. LPG);
- altering a vehicle to make it a snow-clearing vehicle;
- altering a vehicle in order to carry people with reduced mobility in wheelchairs;
- modification of the gross vehicle mass (Masse Maximale Autorisée - MMA), etc.
A vehicle that has been transformed or altered technically must be checked and/or accepted before its next technical inspection is due, and at any rate within two months of completion of the transformation or alterations.
Having your vehicle checked and/or accepted may involve your vehicle being physically checked.
If so, you will have to take your vehicle to one of the SNCA's sites.
The site at Sandweiler will be able to deal with all acceptance cases.
The sites at Esch-sur-Alzette and Marnach will be able to deal with 80% of acceptance cases. Please check with the SCNA in advance which site(s) will be able to deal with acceptance for your vehicle.
A physical check is carried out to check that your vehicle complies with the legislation in force.
Your vehicle should be clean and in good working order. The vehicle data plate affixed by the manufacturer, the chassis number (stamped into the chassis or hull), and the engine identification plate or number should be located and cleaned.
Otherwise, or if you have any difficulties, it is recommended that you contact a professional (dealer, garage, etc.), who should be able to help.
On the day of the physical check, you must present all the documents (manufacturer's agreement (accord constructeur), expert's report drawn up by an approved technical service, acceptance notes/certificates from an approved body for vehicle approval, etc.) relating to changes and alterations made to the vehicle.
Once it has been determined that your vehicle meets the legal requirements, you can start on the registration procedure.
