Technical harmonisation

Technical harmonisation

Technical harmonisation for motor vehicles and their trailers, implemented at Union level pursuant to Article 114 of the Treaty on the Functioning of the European Union (TFEU), is based on the EC Whole Vehicle Type-Approval system (EC WVTA).


Under this system, manufacturers can obtain approval for a vehicle type in one Member State if it meets the Community technical requirements, and then market it EU-wide with no need for further tests or checks. Registration must be granted on simple presentation of a certificate of conformity.

Total technical harmonisation has already been achieved in many vehicle categories (light and heavy duty vehicles, motorcycles and some agricultural and forestry tractors) and will soon be extended to other vehicle categories (other tractors and their trailers and towed equipment).

It is essential that European manufacturers be ensured access to as large a market as possible. While the Community type-approval system allows manufacturers to benefit fully from the opportunities offered by the internal market, worldwide technical harmonisation in the context of the United Nations Economic Commission for Europe (UNECE) offers them a market which extends beyond European borders.
