Vehicles that are subject to registration must be fitted with number plates before they can be driven on public roads.
The plates must be approved and displayed visibly on the vehicle.
Motorcycles, quadricycles, tricycles, mopeds, light quadricycles and trailers only need one plate, at the rear; all other vehicles must have one plate at the front and one at the rear, both showing the same number.
Under the Luxembourg system, there are two types of registration number:
- numbers of the current series, which remain assigned to you as the holder, for a period of 1 year after the permanently deregistering of a vehicle;
- personalised registration numbers, which remain assigned to you as the holder, for a period of 1 year after the permanently deregistering of a vehicle.
It is prohibited to change the registration number of a vehicle already registered in a person's name.
An exception is made when registration plates are stolen.
