How to declare modifications to a vehicle

Any significant modifications to a vehicle registered in Monaco resulting in a change to the technical characteristics mentioned on the registration certificate must be declared to the Driver and Vehicle Licensing Office so that this registration document can be amended.

In particular, a declaration must be made for the following modifications:

• Changes affecting the technical specifications (power, weight, dimensions, axles, braking, manoeuvring, steering and visibility devices, energy, pollutant emissions and noise, number of seats, etc.)
• The fitting out of a vehicle (campervan, ambulance, shop, extended cab, wheelchair transport, etc.)
• Modification or installation of bodywork (ambulance in a van, installation of a tipper, addition of a side-car, etc.)
• Equipping a vehicle to operate with LPG (liquefied petroleum gas) or the removal of this equipment 
• Derestriction of a motorcycle from category A2 to A, undertaken by a professional
• Etc.

On the other hand, minor modifications, such as the installation of a car seat in a privately owned vehicle, the installation of a navigational aid system, the addition of decorative elements, when they do not reduce the driver's visibility, do not require an amendment to the registration certificate and do not have to be declared.  Only a change of colour of a vehicle, which does not require a change in the registration certificate, must be reported to the Driver and Vehicle Licensing Office by email at the following address circulation@gouv.mc or by post, specifying the characteristics of the vehicle.
