No one likes the stress of an MOT test failure, but did you know that nearly 40% of cars fail their MOT on the first attempt? Whether it’s a minor issue like a faulty bulb or a major problem with your brakes, failing can be frustrating and costly.
But here’s the good news: understanding MOT retests and failures can save you time, money, and hassle. From free retests to common failure reasons, this guide will walk you through everything you need to know so you can get your car back on the road quickly and legally.
Let’s dive into the 10 most important things every driver should know about MOT retests and failures!
1. What is an MOT Retest?
An MOT retest is a follow-up inspection to check if the issues that led to the initial failure have been fixed. If your vehicle fails its MOT, you’ll need to carry out the necessary repairs before it can be legally driven on the road again.
2. Common Reasons for MOT Failure
Many vehicles fail their MOT due to minor issues that could have been easily prevented. Some of the most common reasons for failure include:
- Faulty lights and indicators
- Worn-out tires with insufficient tread depth
- Brake system issues
- Windscreen cracks or damaged wipers
- Excessive emissions
- Suspension problems
By checking these components before your MOT, you can increase your chances of passing on the first attempt.
3. Where to Get an MOT Retest in Chatham?
If you’ve failed your MOT and need a retest, choosing a trusted garage is crucial. MOTs in Chatham are conducted by licensed garages that ensure your vehicle meets safety and environmental standards. Some garages even offer free retests within a specific period if you get the repairs done with them.
4. Free MOT Retest Rules
You may be eligible for a free MOT retest if you leave your vehicle at the testing center for repairs and get it retested within 10 working days. However, if you take your car away for repairs and return after this period, you may have to pay the full test fee again.
5. Partial vs. Full Retest
- Partial Retest: If your vehicle only failed on minor issues like lights, mirrors, or windscreen wipers, a partial retest is done. In many cases, this is free if completed within one working day.
- Full Retest: If major repairs are needed (e.g., brake system issues), a full retest is required, and a fee may apply.
6. Can You Drive After Failing an MOT?
If your MOT has expired and your car fails the test, you cannot legally drive it on public roads except when traveling to a garage for repairs. If caught driving without a valid MOT, you risk fines of up to £1,000.
7. How to Reduce the Chances of Failing an MOT
Regular maintenance and pre-MOT checks can help you avoid unnecessary failures. Here are a few simple steps to prepare for your MOT:
- Check your lights and replace any blown bulbs.
- Ensure your tires meet the legal tread depth (1.6mm minimum).
- Top up engine fluids, including brake fluid and screenwash.
- Test your wipers, horns, and seatbelts for proper function.
- Look for any dashboard warning lights and address them before your test.
These small fixes can save you time and money on unnecessary retests.
8. How Long Do You Have to Fix MOT Failures?
Once your vehicle fails an MOT, you typically have up to 10 working days to fix the problems and return for a retest. If you exceed this period, a full MOT test may be required instead of a partial retest.
9. Appeal Process: What If You Disagree with an MOT Failure?
If you believe your car failed unfairly, you have the right to appeal. You can:
- Speak to the testing center to clarify the failure reasons.
- Request a VT17 appeal form from the Driver and Vehicle Standards Agency (DVSA).
- Submit the form along with a fee for an independent assessment.
Keep in mind that if the appeal is unsuccessful, you’ll need to pay for a new MOT test.
10. The Importance of Regular Car Servicing
Many MOT failures can be avoided by getting your car serviced regularly. While servicing isn’t a legal requirement like an MOT, it helps keep your vehicle in top condition and prevents costly repairs. Booking an annual service before your MOT test can help identify potential issues early and improve your chances of passing.
Final Thoughts
Failing an MOT can be frustrating, but with the right preparation, you can minimize the chances of it happening. Regular car maintenance, pre-MOT checks, and choosing a reliable garage for MOTs in Chatham can make the process smoother. If your car does fail, understanding the retest rules and acting quickly can save you time and money.
