What to Do If Your Car Fails Its MOT – Complete 2026 Guide for London Drivers

Read Article

If you’re a London driver who’s just failed an MOT test, you’re not alone – and it’s not the end of the road. Many car owners feel frustrated or confused about what happens next: Can you still drive? Who pays for repairs? Will you need to book another test?

At Auto King, we’ve seen this situation hundreds of times. Our AA-approved mechanics in Bethnal Green, London, help drivers understand their VT30 failure notice, fix issues quickly, and get their cars back on the road  – safely and legally. Let’s walk you through what to do step by step.

what to do if your car fails mot

Step 1: Understand Your MOT Refusal Notice (VT30)

When your vehicle fails an MOT, the testing centre issues a VT30 Refusal of an MOT Test Certificate.

This document lists every reason for failure and categorises each fault as:

  • Dangerous: The car is unsafe to drive and must not be moved on public roads.
  • Major: The car failed, but you can drive it for repairs or a retest if your previous MOT is still valid.
  • Minor: Not serious enough to fail the test but must be fixed soon.

Tip: Keep your VT30 safe – you’ll need it for your repair records and the retest.

Step 2: Decide Where to Get Repairs Done

You have two options:

  1. Leave the car at the same MOT test centre.
    • If you do this, you’ll likely qualify for a free partial retest within 10 working days.
  2. Take it to another garage for repairs.
    • You can drive the car only if it has no dangerous faults and your previous MOT is still valid.

At Auto King, we specialise in MOT failure repairs – from brakes and suspension to emissions issues. Because we’re fully equipped for diagnostics and mechanical work, we can repair and retest your car in one visit.

Step 3: Know When You Can Drive After a Failed MOT

Whether you can legally drive depends on the fault severity:

  • Dangerous fault: ❌ Do not drive the car – not even to another garage.
  • Major fault: ✅ You may drive it to a pre-booked repair or retest appointment if your previous MOT hasn’t expired.
  • Minor fault: ✅ Your MOT will pass, but you’ll need to fix these soon.

Driving a car with a dangerous fault can lead to a £2,500 fine, 3 penalty points, or even a driving ban. Always check the VT30 carefully before setting off.

Step 4: Book Your MOT Retest

You don’t have to start from scratch. Here’s how MOT retests work:

Scenario Retest Type Cost
You leave the car at the same test centre for repairs Free partial retest £0
You take the car elsewhere but return within 1 working day Free retest £0
You bring the car back after 1 working day Full retest required Standard MOT fee

Auto King offers MOT repairs and same-day retests for most vehicles, so you can get back on the road without unnecessary delays.

Step 5: Keep Track of Your MOT History

Once your car passes, the result is automatically uploaded to the DVSA MOT database, and you’ll receive a new certificate.

You can check your MOT history anytime at gov.uk/check-mot-history.

At Auto King, we always update your MOT results digitally – making it easy to track when your next test is due.

Step 6: Prevent Future MOT Failures

Most MOT failures come from issues that could’ve been fixed earlier.

Here’s how to avoid them next time:

  • Check your tyre tread depth (at least 1.6mm).
  • Make sure brake lights, indicators, and wipers work.
  • Keep your windscreen clean and crack-free.
  • Get a regular full service before your MOT to catch wear and tear early.
  • Book a pre-MOT inspection – something Auto King offers to spot potential fails before test day.
