How to Handle Dangerous or Major Faults in Your MOT Report

2025-09-26

Receiving an MOT report that highlights dangerous or major faults can be stressful. These issues not only prevent your car from passing the MOT but also pose serious risks to road safety. Understanding what these faults mean, the legal implications, and the steps you should take next is essential for every UK driver.

What Are Dangerous and Major Faults?

During an MOT test, vehicle defects are classified into categories:

  • Dangerous faults – These pose an immediate risk to road safety or the environment. Driving the car is illegal until repairs are made.
  • Major faults – These are serious problems that mean the vehicle does not meet the legal standards, though not always as critical as dangerous faults. Repairs must be carried out before the car can pass the MOT.

Both categories result in an MOT failure.

Legal Consequences of Driving With Faults

If your car is issued with a dangerous fault, it is illegal to drive it away from the test centre until it has been repaired. Doing so can result in:

  • Fines of up to £2,500.
  • Three penalty points on your licence.
  • A potential driving ban in severe cases.

With major faults, you cannot legally use your car until the necessary repairs are completed and it passes a retest.

Steps to Take After a Failed MOT

  1. Review the MOT report carefully – Check exactly which faults are listed and their classification.
  2. Get repair quotes – Ask your MOT centre or other trusted garages for repair costs.
  3. Decide on immediate repairs – For dangerous faults, repairs must be carried out before you can drive the vehicle.
  4. Book a free MOT retest – Many garages offer a free retest within 10 working days once repairs are completed.
  5. Keep records – Save receipts and updated certificates for proof of compliance.

Preventing Future MOT Failures

Regular maintenance can reduce the risk of dangerous or major faults appearing on your MOT report. Key habits include:

  • Checking tyres, brakes, and lights regularly.
  • Keeping up with scheduled servicing.
  • Addressing dashboard warning lights promptly.
  • Getting pre-MOT checks done to catch issues early.

Conclusion

Dangerous and major faults on your MOT report should never be ignored. While they may seem daunting, taking swift action ensures your car remains safe, roadworthy, and legally compliant. By understanding your responsibilities and staying proactive with maintenance, you can reduce the risk of serious faults affecting your vehicle in the future.
