Annual test (MOT) for lorries, buses and trailers
1. Vehicles that must take the 'annual test'
The annual test is for:
- goods vehicles with a gross weight of more than 3,500 kilograms (kg)
- vehicles that are built or have been adapted to form part of an articulated vehicle
- horseboxes with a gross weight of more than 3,500kg
- ‘A’ frame trailers and converter dollies manufactured on or after 1 January 1979
- trailers with an unladen weight of more than 1,020kg with powered braking systems (instead of standard overrun brakes and as well as the required parking brake)
- all public service vehicles with more than 8 passenger seats - not including the driver’s seat
About the test
Lorries and buses (including coaches) must be tested each year. The first test should be 12 months after the vehicle was first registered with DVLA (Driver and Vehicle Licensing Agency).
Trailers must be tested one year after they were first sold or supplied.
The test can be done at a Driver and Vehicle Standards Agency (DVSA) test station or a privately owned Authorised Testing Facility (ATF). Both use DVSA staff and the same test standards.
