MOT in Great Britain: expiry, preparation and what a failure means
Check your MOT on GOV.UK, prepare safely and understand major, dangerous and advisory results.
1. Check and book on GOV.UK
Use the official free MOT history service with the registration. GetCarCode does not currently provide a working UK MOT-history lookup.
For most ordinary cars in Great Britain the first MOT is at three years, then annually. Northern Ireland has different rules and booking arrangements.
You can normally test up to one month minus a day before expiry and keep the renewal date.
2. Prepare without hiding faults
Check lights, tyres, washers, wipers and seat belts. Arrange repair for braking faults, warning lights or exhaust leaks before the appointment.
An engine warning can fail applicable vehicles. Clearing codes is not a repair; the exact emissions procedure depends on age and fuel type.
3. Read a failure carefully
Major or dangerous defects cause a failure; advisories and minor defects may still need attention. Ask for a repair quote item by item.
You may take a failed vehicle away only if the existing MOT is still valid, no dangerous defects are listed and it remains roadworthy. Otherwise arrange repairs or recovery; do not assume an old certificate overrides a dangerous defect.
Frequently asked questions
Can I drive with an expired MOT?
Generally you cannot drive or park on the road. GOV.UK lists limited exceptions for a pre-arranged test or travel to or from repairs; the vehicle must still be safe and meet other legal requirements.
Is an advisory a failure?
No, but it is a warning to monitor or repair an issue. A recurring tyre or suspension advisory deserves attention before purchase.
