The dreaded MOT test. For many car owners, it's a necessary evil, a yearly hurdle to overcome to ensure their vehicle is roadworthy and safe. But what happens if, despite your best efforts, your car fails to meet the required standards? The immediate thought might be a wave of panic, but understanding the process can alleviate a great deal of stress. This guide will walk you through exactly what happens if your vehicle fails its MOT, what your options are, and how to get your car back on the road legally and safely.

Understanding the MOT Test and Failure Categories
The Driver and Vehicle Standards Agency (DVSA) conducts the MOT test, ensuring vehicles meet stringent safety and environmental requirements. When your car is tested, it's assessed against a comprehensive list of components. If any of these components are found to be defective, they fall into one of three categories: Dangerous, Major, or Minor. The outcome of your test will depend on the severity of these defects.
Dangerous Defects
These are the most serious issues. If your car has a 'Dangerous' defect, it is illegal to drive it on the road until the necessary repairs are completed. You cannot drive the car to a place of repair, even if it's to the same testing centre. You'll need to arrange for it to be towed or transported. Examples include a leaking brake fluid reservoir, a tyre with exposed structural ply, or a faulty headlight.
Major Defects
A 'Major' defect means your car will fail its MOT. While not as immediately dangerous as a 'Dangerous' defect, it still requires repair to be roadworthy. You can usually drive your car to a place of repair with a 'Major' defect, provided the current MOT certificate is still valid. However, it's advisable to get these issues addressed as soon as possible. Examples include worn brake pads, a faulty indicator, or a corroded exhaust system.
Minor Defects
These are issues that don't pose an immediate risk but should be monitored and repaired in the near future. A car with only 'Minor' defects will still pass its MOT. However, these will be listed on your MOT certificate as advisories, and you should address them before they become more serious problems.
What to Do Immediately After Failing Your MOT
Upon failing the test, you will be given a 'Refusal of an MOT Test Certificate' (VT30) if your vehicle has dangerous defects. If it has major defects but no dangerous ones, you'll receive a 'First Test Pass Certificate' (VT32) with the advisories listed, indicating it has failed the overall test. It's crucial to understand that having a valid MOT certificate is a legal requirement for driving on UK roads. Without one, your car is uninsured, and you could face fines and penalties.
Driving After Failing the MOT
The rules regarding driving a car that has failed its MOT are strict and depend on the nature of the defects:
- Dangerous Defects: It is illegal to drive your vehicle on the road. This includes driving it to a garage for repair. You must arrange for it to be towed or transported.
- Major Defects (but no Dangerous Defects) and the previous MOT has expired: You can drive your vehicle to a pre-arranged appointment at a place of repair. However, if your previous MOT certificate is still valid, you can continue to drive as normal until it expires, but you must get the repairs done before then.
- Major Defects (but no Dangerous Defects) and the previous MOT is still valid: You can continue to drive your vehicle until the current MOT certificate expires. However, you must have the necessary repairs completed before the expiry date.
It is essential to be aware of the validity of your current MOT. If your MOT has already expired, you cannot legally drive the car to a garage for repairs, even if the failed MOT was conducted at that very garage. The only exception is if you are driving to a pre-booked MOT appointment, but this is only permissible if the previous MOT certificate is still valid.
Getting Your Car Repaired
Once you have your MOT failure report, you can start the repair process. You have several options:
Option 1: Repair at the Testing Centre
Many MOT centres offer repair services. If your car has failed, you can often have the repairs carried out by the same garage. If the repairs are completed and the vehicle is re-tested within 10 working days of the original failure, you may be eligible for a partial re-test, which is often free or at a reduced cost. This can be a convenient option, as they will already be familiar with the issues.
Option 2: Take it to Another Garage
You are not obligated to have your car repaired at the original testing centre. You can take your vehicle (either by towing or by driving if legally permitted) to a different garage of your choice. This allows you to shop around for the best prices and potentially find a specialist for specific repairs.
Option 3: DIY Repairs
If you have the necessary skills and tools, you might consider carrying out the repairs yourself. However, be absolutely certain that your repairs meet the required standards. If you're unsure, it's always best to consult a professional. Remember, the responsibility for ensuring the car is roadworthy lies with you.
The Re-test: Getting Back on the Road
After your car has been repaired, it will need to undergo a re-test. The process and cost of the re-test depend on when you present the vehicle for re-testing:
Partial Re-test:
- If your car is repaired and presented for a partial re-test within one working day of the original failure, only specific items that caused the failure will be checked.
- If presented within 10 working days, certain components will be re-checked, but the entire test might not be repeated. This is often free or at a reduced rate.
Full Re-test:
- If you present your car for re-testing after 10 working days, or if the repairs haven't been completed correctly, it will require a full MOT re-test, and you will have to pay the full MOT fee again.
It's vital to keep the original failure certificate (VT30) as proof of the defects found, which can help the new testing centre focus on the necessary repairs.
Common Reasons for MOT Failure
Understanding why cars typically fail their MOT can help you proactively maintain your vehicle:
| Category | Common Failures |
|---|---|
| Braking System | Worn brake pads or discs, low brake fluid, faulty brake pipes, handbrake not holding the vehicle on a roller. |
| Tyres | Tyres with less than 1.6mm tread depth, cuts or bulges on the sidewalls, incorrect tyre pressures. |
| Lights | Missing, broken, or incorrectly aimed headlights, faulty indicator lights, non-functioning brake lights. |
| Visibility | Worn or damaged windscreen wipers, cracked or obscured windscreen, faulty horn. |
| Suspension & Steering | Worn suspension components (e.g., ball joints, shock absorbers), loose steering components, damaged steering rack. |
| Exhaust & Emissions | Excessive emissions, leaking exhaust system, corroded exhaust components. |
| Body & Chassis | Significant corrosion in structural areas, sharp edges causing a hazard, damaged body panels affecting safety. |
What if I Can't Afford the Repairs?
If the cost of repairs is prohibitive, you have a few options:
- Sell the car for parts: If the car is too expensive to repair, you might consider selling it to a scrap dealer or breaker's yard. They will typically offer a price for the vehicle, often based on its weight and any valuable components.
- Sell the car as-is: You could try to sell the car privately, being completely transparent about the MOT failure and the necessary repairs. Someone with more mechanical expertise or a lower budget might be willing to take it on. However, remember it's illegal to drive the car to a buyer if it has dangerous defects or an expired MOT.
FAQs about Failing an MOT
Q1: Can I still drive my car if it fails its MOT?
You can only drive your car if its previous MOT certificate is still valid and the failure does not include 'dangerous' defects. You must then get the repairs done before the current MOT expires. If the MOT has expired or the defects are 'dangerous', you cannot legally drive it on public roads.
Q2: How long do I have to get my car repaired after failing the MOT?
There is no strict deadline to get the repairs done, but you cannot drive the car legally if its MOT has expired or if it has 'dangerous' defects. If the previous MOT is still valid, you must complete the repairs before it expires.
Q3: Is a free MOT re-test guaranteed?
Not all re-tests are free. If your car fails and you leave it at the testing centre for repair, and it's re-tested within one working day, it's usually free. If it's re-tested within 10 working days, it's often at a reduced rate. If you take it elsewhere or leave it longer than 10 working days, you'll likely have to pay for a full re-test.
Q4: What happens if I get caught driving a car with a failed MOT?
If you are caught driving a car with a failed MOT (especially with dangerous defects or an expired MOT), you could face a fine of up to £2,500, receive penalty points on your licence, and your vehicle may be impounded. Your insurance may also be invalidated.
Q5: Can I sell a car that has failed its MOT?
Yes, you can sell a car that has failed its MOT. However, it is illegal to drive it on the road. You must inform the buyer that it has failed and what repairs are needed. It's often best to have the repairs done before selling, or to sell it to a breaker or someone who can repair it.
Conclusion
Failing an MOT test can be a stressful experience, but it's a crucial part of road safety. By understanding the different categories of defects, your legal obligations, and the available repair and re-test options, you can navigate the process smoothly. Regular maintenance and addressing advisories promptly can help prevent failures in the first place, keeping you and other road users safe, and ensuring your vehicle remains legal to drive.
