You need to get an HGV, bus or trailer MOT (also known as an ‘annual test’) 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 (such as buses and coaches) with more than 8 passenger seats - not including the driver’s seat
MOT due dates
HGVs and buses (including coaches) usually must be tested each year. The first test should be 12 months after the vehicle was first registered with the Driver and Vehicle Licensing Agency (DVLA).
Trailers must usually be tested one year after they were first sold or supplied.
Before the test
You can get your vehicle checked by a qualified mechanic to prepare for the test.
Get testing manuals for different vehicles.
You can also download a guide on how to check the roadworthiness of horseboxes and trailers.
How to clean your vehicle
You must clean the inside of your vehicle before your test.
- tidying unnecessary items from the dashboard, footwells, door pockets and seats
- wiping down the dashboard, doors and vehicle controls
Your test will be cancelled and you’ll have to pay again if the vehicle is not clean.
