Your vehicle can either pass or fail the MOT. If it fails, you'll get a list of things that need to be fixed.
Passing the MOT
If your vehicle passes the MOT:
you'll get an MOT certificate from the test centre
it will be recorded in the MOT database
Mileage reading
The MOT certificate will show the mileage recorded at the current and previous 3 test passes. This is shown as the 'odometer reading and history'.
Report any mistakes with the latest reading to the MOT centre within 7 days. They will give you a replacement certificate.
Mistakes on an earlier mileage can't be changed.
Failing the MOT
If your vehicle fails the MOT:
you'll get a 'refusal of an MOT test certificate' from the test centre
it will be recorded in the MOT database
You can appeal the result if you think it's wrong.
Driving a vehicle that's failed
You must not drive the vehicle on the road if it fails the test, even if the MOT hasn't run out, except to:
have the failed defects fixed
a pre-arranged MOT test appointment
You can be fined up to £2,500, be banned from driving and get 3 penalty points for driving a vehicle in a dangerous condition.
