A vehicle registration certificate is an official document showing proof of registration of a motor vehicle.
Registration certificate (certificate of registration), suitably translated or in certain cases a technical supplementary statement, including EC directives on exhaust gas emissions, braking, steering, seat belts etc. or the C.O.C. (Certificate of Conformity) for which a photocopy is sufficient.
According to EU legislation, technically it is not necessary for a used vehicle from another EU country to undergo a roadworthiness test (collaudo), as demanded by Article 75 of the Highway Code, if the validity of the final technical inspection carried out abroad can be deduced from the original document.
It is used primarily by governments as a means of ensuring that all road vehicles are on the local vehicle register, but is also used as a form of law enforcement and to facilitate change of ownership when buying and selling a vehicle.

In order to register your car, you need to prove that you reside legally in Italy and own the car. If your car is used, it needs to pass an inspection before you can get your plates. This should make sure that it complies with Italian safety and technical standards. Basically the following rule applies: If your car is more than six months old and has more than 6,000 kilometers on the mileage counter, it is considered used.
