Type Approval for Agricultural and Forestry Vehicles T1 to T4, R and S; and OECD

This page was last updated on 13th February 2020

A system of mandatory European Community Whole Vehicle Type Approval (ECWVTA) has been in place for agricultural and forestry tractors, their trailers and interchangeable towed equipment (T1, T2, T3, T4, R and S) for a number of years. It also covers systems, components and separate technical units for these vehicles.  An EU Framework Regulation (EU) 167/2013 and 5 implementing EU Regulations set out the requirements.

The Whole Vehicle approval framework regulation (EU 167/2013) provides for the approval of whole vehicles systems, components and separate technical units. Through a suite of implementing regulations it also includes a package of subordinate requirements for vehicle systems and separate components, which are based around a mixture of EU Regulations and UN Regulations. This certification is accepted throughout the EU without the need for further testing until a standard is updated or the vehicle design changes.

A manufacturer holding an EU type approval can produce unlimited numbers of vehicles for distribution in the whole of the EU.

Automotive EU instruments and UN ECE Regulations require third party approval – testing, certification and production conformity assessment by an independent body.


The Organisation for Economic Co-operation and Development (OECD) oversees a series of Codes that apply to the testing of agricultural and forestry tractors, the codes are applied in addition to other forms of testing and are required in a number of countries around the world, both inside and outside of the European Community.

VCA is the UK National Designated Body for OECD for agricultural and forestry tractors.
