Understanding Your MOT Failure and What to Do

The annual MOT test is a crucial part of vehicle ownership in the UK, designed to ensure your car is safe and environmentally sound. While many drivers pass with flying colours, a significant number of vehicles fail to meet the required standards each year. If your car has failed its MOT, it can be a stressful experience, leaving you wondering about the next steps and the implications for your driving. This guide will demystify the process, explaining exactly what happens after a failure, common reasons for it, and how to rectify the issues to get your vehicle legally back on the road.

Do you need a retest if your car fails the MOT?

What Happens Immediately After Failing an MOT?

If your vehicle fails its MOT test, the tester will provide you with a 'Refusal of an MOT Test Certificate'. This document, often referred to as a VT30, details the reasons for the failure. Critically, it is illegal to drive a vehicle that has failed its MOT, unless you are driving it to a pre-booked appointment for repair or to a pre-booked MOT test. Driving a vehicle with an expired MOT certificate, or one that has failed, can result in a hefty fine and penalty points on your licence.

Can You Drive Your Car After Failing the MOT?

As mentioned, you can only legally drive your car after it has failed its MOT if you are taking it to a pre-booked appointment for repair or to a pre-booked MOT test. You must be able to prove this appointment if stopped by the police. If your car is not roadworthy, you will need to arrange for it to be towed or transported to a garage for repairs. Driving it without the necessary repairs constitutes an offence.

Do You Need a Retest if Your Car Fails the MOT?

Yes, absolutely. Once the necessary repairs have been carried out, your vehicle will need to undergo a partial or full retest to ensure it now meets the required standards. The type of retest depends on when you bring the vehicle back to the testing station.

Types of MOT Retests:

  • Retest within 1 working day: If you take your car back to the same test centre within one working day of failing, only the items that failed will be re-examined. This is often a free service.
  • Retest after more than 1 working day: If you take your car back to the same test centre after one working day has passed, a full MOT test will be required again. This means you will have to pay the full MOT fee.
  • Retest at a different test centre: If you take your car to a different test centre, a full MOT test will be required, and you will pay the full fee.

It's important to note that the 'working day' rule excludes weekends and bank holidays. Therefore, if your car fails on a Saturday, it must be returned by the close of business on the following Monday to qualify for the partial retest (assuming Monday is not a bank holiday).

Common Reasons for MOT Failures

Understanding why cars fail their MOT can help you proactively maintain your vehicle and potentially avoid a failure. The Driver and Vehicle Standards Agency (DVSA) publishes data on common failure points. Here are some of the most frequent culprits:

Failure CategoryCommon Issues
Lighting and Signalling
  • Incorrectly aimed or faulty headlights
  • Broken or missing rear lights
  • Malfunctioning indicators
  • Incorrect bulb types
Brakes
  • Worn brake pads or discs
  • Low brake fluid levels
  • Faulty brake pipes or hoses
  • Improper brake performance
Tyres
  • Tyres with tread depth below the legal limit (1.6mm)
  • Damaged or perished tyres (cracks, bulges)
  • Incorrect tyre pressures
  • Tyres of different specifications on the same axle
Visibility
  • Worn or damaged windscreen wipers
  • Cracked or damaged windscreen (affecting driver's view)
  • Dirty or obscured mirrors
Suspension
  • Worn shock absorbers
  • Damaged springs or suspension arms
  • Excessive play in suspension components
Exhaust and Emissions
  • Leaking exhaust system
  • Excessive noise from the exhaust
  • High CO2 emissions
  • Missing or damaged catalytic converter
Body and Structure
  • Significant rust or corrosion (especially on structural components)
  • Sharp edges or protrusions that could injure pedestrians
  • Loose or damaged body panels
Steering
  • Excessive play in the steering wheel
  • Worn steering components (e.g., track rod ends)
  • Stiff steering

What are 'Dangerous Defects'?

The VT30 certificate categorises defects into three types: minor, major, and dangerous. Minor defects are advisory and do not cause a failure. Major defects will cause a failure and must be repaired. Dangerous defects are even more serious. If your car has a dangerous defect, it must not be driven under any circumstances until it is repaired. Driving with a dangerous defect is illegal and extremely hazardous.

What to Do if Your Car Fails the MOT

The first and most important step is to understand the issues listed on the VT30. If the defects are classified as dangerous, you must not drive the car. Arrange for it to be towed to a garage. If the defects are major but not dangerous, you have a limited window to get them repaired and retested.

1. Get a Quote for Repairs:Once you know what needs fixing, get quotes from a reputable garage. You can choose to have the repairs done by the MOT centre or take your car elsewhere. Compare prices to ensure you're getting good value.

2. Authorise Repairs:Once you're happy with a quote, authorise the repairs. It's a good idea to ask the garage to show you the old parts if possible, so you can see what was wrong.

3. Arrange the Retest:After the repairs are complete, arrange for the retest. Remember the timeframes mentioned earlier to potentially save on the retest fee. If your car failed due to a dangerous defect, it will need to be towed to the testing centre for the retest.

4. Check Your New MOT Certificate:Once your car passes the retest, you will receive a new MOT certificate. Ensure all the details are correct.

Can You Repair Your Car Yourself?

Yes, if you have the mechanical knowledge and the necessary tools, you can carry out the repairs yourself. However, you must ensure that the repairs meet the required MOT standards. If you're unsure, it's always best to use a professional mechanic. If you do the repairs yourself, you'll still need to take the car for a retest.

What if Your MOT Has Expired?

If your MOT certificate has expired, you cannot legally drive your car on the road until it has passed a new MOT test. You will need to arrange for the vehicle to be transported to an authorised testing centre. The only exception is if you are driving to a pre-booked MOT test appointment.

Frequently Asked Questions (FAQs)

Q1: How long do I have to get my car repaired after failing the MOT?
There is no strict time limit to get the repairs done, but you cannot legally drive the car unless it has a valid MOT certificate or is en route to a pre-booked repair or retest. Your previous MOT certificate is invalidated upon failure, so you must address the issues promptly.

Q2: Can I get an MOT retest at any garage?
For a partial retest (free or reduced fee), you generally need to return to the original testing station. For a full retest, you can go to any authorised MOT test centre, but you will pay the full test fee.

Q3: What if my car fails the MOT but the certificate is still valid?
If your car fails the MOT but the certificate is still valid, you can continue to drive it until the expiry date. However, you must arrange for the necessary repairs to be carried out. It is highly recommended to get the repairs done as soon as possible and book a retest to ensure you can legally drive the car once the original MOT expires.

Q4: What are the penalties for driving a car with a failed MOT?
Driving a car that has failed its MOT can result in a fine of up to £1,000, and in some cases, you may also receive penalty points on your driving licence. If the failure is due to dangerous defects, the penalties can be more severe, and the vehicle may be impounded.

Q5: Is a retest always necessary?
Yes, if your car fails the MOT, a retest is always necessary to confirm that the repairs have been made correctly and the vehicle now meets the minimum required standards for roadworthiness.

Conclusion

Failing an MOT can seem daunting, but by understanding the process and your options, you can navigate it effectively. Promptly addressing the issues highlighted on the VT30, understanding the retest procedures, and ensuring all repairs are carried out to a high standard will get your car back on the road safely and legally. Regular maintenance and pre-emptive checks can also significantly reduce the likelihood of a failure in the first place, saving you time, money, and stress.
