In order to register a vehicle there are certain documents which are needed for the car to undergo an inspection known as the ‘ITV’ (inspeccion tecnica de vehiculos).
These tests can only be carried out at an official ITV testing station and an appointment is required.
It is important for the vehicle to pass the Spanish inspeccion tecnica de vehiculos (ITV) test in order to receive permanent registration number. If a vehicle fails the test, necessary repairs must be done on the vehicle within two months of the test.
If the vehicle is not tested again during the two month period, then the vehicle may get deregistered. In case of classic cars, there is a special test required as well as a certificate of authenticity to be issued by the regional authorities (comunidad autonoma)
