Failed your MOT? What happens next

By Martin Harvey, MH Auto Services · Published 19 October 2026

The short answer

A car fails its MOT when the result lists any "dangerous" or "major" problems. If your current MOT is still valid and nothing dangerous was listed, you can drive it away and get it repaired. If something dangerous was listed, it needs fixing before it goes back on the road.

Dangerous, major, minor and advisory

The result sorts problems into groups. Dangerous and major problems mean a fail. Minor problems and advisories don't fail the car, but they're listed so you can monitor them or fix them later. It's worth reading the advisories: they're often next year's fails.

Can you still drive it?

GOV.UK sets out two situations where you can take the car away after a fail: your current MOT is still valid, or no dangerous problems were listed. In either case the car "must still meet the minimum standards of roadworthiness at all times."

The penalty for getting it wrong is serious. GOV.UK says you can be fined up to £2,500, banned from driving and given 3 penalty points for driving a vehicle that failed because of a dangerous problem.

You can check any car's MOT expiry date, results and advisories with the free MOT history checker on GOV.UK.

What fails most often

About 29% of cars fail first time. DVSA test data, reported by Motorpoint, puts these areas at the top:

• Lamps, reflectors and electrical equipment: 11.41%
• Suspension: 9.08%
• Brakes: 6.85%
• Tyres: 6.53%
• Visibility: 4.47%
• Body, chassis and structure: 3.63%

Some of these are quick to check yourself before a test: every bulb, tyre tread and condition, wipers and washer fluid. Rust in the structure is a different matter, and our guide to MOT corrosion failures explains how testers judge it.

Getting the repairs done

GOV.UK says the retest rules depend on where the repairs happen. If the car is left with the test centre for repair and retested within 10 working days, the partial retest is free. If you take it away for repairs and bring it back to the same test centre within 10 working days, you may pay a partial retest fee. Some small items, such as wipers, mirrors and the horn, can be fixed and the car brought back by the end of the next working day without paying again. Otherwise a full retest is needed.

We don't carry out MOT tests ourselves, but we do the repairs. Send a photo of the failure sheet on WhatsApp to 07843 699463, or bring it with the car, and we'll quote for each item before any work starts. That includes welding to MOT standard if the car has failed on corrosion. See MOT preparation and repairs and brake repairs.
