Vehicles with an EU type approval can be marketed anywhere in the European Community. Therefore, a vehicle only needs to receive the type approval certification in one EU country in order to be accepted in all of the other member countries. To receive a type approval, products may either be brought to a testing facility or manufacturers may opt to maintain their own testing equipment. Nevertheless, US and EU automobiles still must be certified to this single set of rules by an authorised member state agency. A similar system was adopted for the type approval of two- and three-wheeled vehicles, which became effective on 1 January 1994.
