Annual test (MOT) for lorries, buses and trailers

At the test station

Bring the following documents to the test station:

  • your appointment letter if you have one
  • the vehicle’s last annual test certificate
  • the vehicle’s plating certificate
  • if your vehicle is exempt - a tachograph exemption form

You’ll need to drive your own vehicle during the test unless otherwise asked.


You should load the horsebox with heavy items like bags of feed, fertiliser or straw bales. This is so that the centre can check the brakes work properly.

Tell the test station about any changes you’ve made to the horsebox since its last test.

There is more information about testing standards for horseboxes in the guide for horsebox and trailer owners.


If an inspector thinks minor repairs are needed to your vehicle and they can be done quickly and safely you may be allowed to do so, but only if it doesn’t delay the testing of other vehicles

Driver and Vehicle Standards Agency (DVSA) staff can’t provide tools or materials or help with repairs.

Failing the test

If your vehicle fails the annual test you’ll have to take it away and get the faults fixed.

Unlike with an MOT, most centres won’t be able to make the repairs for you. Once they’re made you’ll have to book another test and pay a retest fee.

Major faults

Some faults are so serious that the vehicle can’t be allowed on the road. In this case, the inspector may allow on-site emergency repairs.

If you disagree with a test result

You might be able to change your test result.

You’ll need to explain why you disagree. You can either:

  • talk to the assessor at the test station when you get your result
  • contact DVSA if the assessor isn’t available or you leave the testing station after you get the result

DVSA might arrange for the vehicle assessor to look at your results or to test your vehicle again. It needs to be in the same condition as when you got it tested.

You can appeal the result if it doesn’t change.


You can appeal if you’ve tried to change your test result and you still disagree with it.

You need to submit an appeal form within 14 days of the test:

Send the appeal to the address on the form or to the test station that carried out the test.

You’ll also need to pay an appeal fee.
