The annual MOT (Ministry of Transport) test is a vital check to ensure your vehicle meets the minimum safety and environmental standards required to be driven on UK roads. It's a moment of truth for many vehicle owners, and while we all hope for that coveted pass certificate, sometimes the outcome is a fail. When that happens, it's natural to feel a mix of disappointment and confusion about what to do next. Understanding the implications of an MOT failure and the subsequent steps is crucial for getting your vehicle back on the road safely and legally. This guide will walk you through what happens when your car fails its MOT and also clarify how the Driver and Vehicle Standards Agency (DVSA) can assist in correcting any potential errors on your MOT record.

Understanding an MOT Test Failure
An MOT failure means your vehicle has defects that make it unsafe or unroadworthy according to current regulations. The testing station will provide you with a 'refusal of an MOT test certificate', which lists all the identified defects. These defects are categorised based on their severity, directly impacting what you can and cannot do next.
Categories of Defects
Since May 2018, MOT defects are categorised into three main types:
- Minor Defects: These are issues that are not severe enough to cause a test failure but should still be repaired as soon as possible. They are recorded on the MOT certificate as 'advisories'. Your vehicle will still pass the MOT with minor defects.
- Major Defects: These are significant issues that could affect the vehicle's safety, impact the environment, or pose a risk to other road users. A vehicle with major defects will fail its MOT.
- Dangerous Defects: These are issues that pose a direct and immediate risk to road safety or the environment. A vehicle with dangerous defects will fail its MOT, and it is illegal to drive it on the road until the defects are rectified.
Driving After an MOT Failure
This is a critical point of confusion for many. If your car fails its MOT, you cannot legally drive it on public roads unless:
- You are driving it to a pre-booked appointment for repairs to fix the defects.
- You are driving it to a pre-booked MOT retest.
Crucially, your vehicle must still be roadworthy, even if you are driving it for repairs or retest. If the defects are categorised as Dangerous defects, it is illegal to drive the vehicle at all until the issues are resolved, even for repairs. Driving a vehicle with a dangerous defect could lead to significant fines, penalty points, and even prosecution. Always ensure your vehicle is insured and taxed, regardless of its MOT status.
Rectification and Retesting
Once your vehicle has failed, the next step is to get the defects fixed. You have a few options:
- Get repairs done at the test centre: Many test centres also offer repair services. If the repairs are done at the same centre and the vehicle is retested within 10 working days, you might qualify for a free partial retest.
- Take the vehicle elsewhere for repairs: You can choose another garage or even perform the repairs yourself if you have the necessary skills and tools.
After repairs, your vehicle needs to undergo a retest. The type of retest and potential cost depend on when and where the retest is conducted:
| Scenario | Retest Type | Cost Implications |
|---|---|---|
| Vehicle left at original test centre and repaired/retested within 10 working days. | Partial retest (only failed items checked). | Usually free. |
| Vehicle taken away for repairs and returned to original test centre within 10 working days. | Partial retest (only failed items checked). | Often free or reduced fee, depending on the test centre and defects. |
| Vehicle returned to original test centre after 10 working days, or taken to a different test centre. | Full MOT test. | Full fee applies. |
It's always advisable to clarify the retest policy and any associated fees with your chosen test centre beforehand.
Correcting Mistakes on an MOT Record with the DVSA
The Driver and Vehicle Standards Agency (DVSA) is the executive agency responsible for ensuring vehicles are roadworthy in the UK, primarily through the MOT test. While MOT testers record results using the MOT testing service, sometimes errors can occur in the official record. The good news is that the DVSA can indeed fix mistakes on an MOT record, provided certain conditions are met.
When and How DVSA Can Help
The DVSA can fix an error on an MOT record if the MOT was carried out more than 28 days ago and you can provide sufficient proof that the record is incorrect. If the MOT was carried out within the last 28 days, you should first contact the garage that performed the test, as they can usually correct recent errors directly.
The process of correcting an MOT record involves providing the DVSA with certain personal data and evidence. This is handled by the Department for Transport (DfT), which acts as the data controller for the DVSA.
Data Collection and Purpose
To process your application to fix an MOT record mistake, the DVSA collects specific personal data. This is essential for them to verify your identity, the vehicle's details, and the validity of your request. The lawful basis for processing this data is classified as a 'public task', meaning it's necessary for the performance of a task carried out in the public interest or in the exercise of official authority.
The personal data typically collected includes:
- Your full name
- Your address
- Your email address
- Your driving licence number
- The vehicle registration mark (VRM)
- Signed authority if someone is acting on your behalf
- Any personal data contained within the evidence you submit
It is critically important that if any of your submitted evidence includes payment details, you must blank out or remove them before sending the documents to the DVSA. This protects your financial information from being unnecessarily shared.
The primary reasons the DVSA needs this data are to:
- Approve or reject applications to fix mistakes on your MOT record.
- Contact you regarding the progress or outcome of your application.
What Happens with Your Data
The DVSA collects, uses, and stores the data you provide strictly for the purposes outlined in their policy. They assure that they will not sell or rent your data to third parties, nor will they share it with third parties for marketing purposes. To ensure the correct person is requesting a change, they have access to registered keeper details within the Driver and Vehicle Licensing Agency (DVLA)'s vehicle services system.
Upon reviewing your submitted information, the DVSA will decide on the next steps. If there's a suspicion of false information being provided or a failure to provide necessary information, the DVSA may decide to investigate. This investigation could involve:
- Sharing your data with DVSA vehicle examiners.
- Sharing your data with other government departments and law enforcement agencies.
Additionally, the DVSA will share your data if legally required to do so, for example, by a court order, or to prevent fraud or other criminal activities. This highlights the importance of providing accurate and truthful information.

Data Retention and Security
The DVSA only retains your personal data for as long as it is necessary for the reasons outlined in their policy or as required by law. Generally, personal data is held for up to one year. However, if an investigation is initiated due to suspected false information or failure to provide information, the data may be held for longer – specifically, no more than 7 years after the end of an investigation or 7 years after the end of any court sentence related to information you provided.
In terms of security, the DVSA confirms that their IT infrastructure and technology are secure. All your data is held on DVSA servers based in the UK or hosted within cloud services located in the European Economic Area (EEA), meeting security safeguards equivalent to those required by data protection legislation. Your privacy is taken seriously, and the DVSA personal information charter outlines the steps taken to protect your data and your rights over it.
It's also worth noting that your data is not subject to automated decision-making or profiling as defined in data protection legislation.
Frequently Asked Questions (FAQs)
Q: Can I drive my car if it has failed its MOT?
A: Only if you are driving it to a pre-booked appointment for repairs or to a pre-booked MOT retest, and the vehicle is still roadworthy. If the defects are categorised as 'dangerous', you absolutely cannot drive it on public roads until fixed.
Q: How long do I have to get my car retested after a failure?
A: If you return your vehicle to the same test centre within 10 working days after the failure, you may qualify for a free or reduced-fee partial retest, checking only the failed items. After 10 working days, or if you go to a different test centre, a full MOT test and fee will apply.
Q: What kind of evidence do I need to correct an MOT record with the DVSA?
A: You'll need proof that the record is incorrect. This could include original MOT certificates, garage invoices for repairs related to the disputed record, or other official documents that contradict the existing record. Remember to blank out any payment details from submitted evidence.
Q: Is my personal data safe when I submit it to the DVSA for a record correction?
A: Yes, the DVSA operates under strict data protection legislation. Your data is stored on secure servers in the UK or EEA and is only used for the purposes of processing your application or for legal requirements, such as fraud prevention. They do not sell or rent your data.
Q: What if I disagree with the MOT failure?
A: If you believe your vehicle wrongly failed its MOT, you can appeal the decision. You must do this within 14 working days of the test. You'll need to fill in an appeal form (VT17) and send it to the DVSA. They will then arrange for an independent examiner to re-examine your vehicle.
Conclusion
An MOT test failure can be a hassle, but it's a crucial mechanism to ensure our vehicles are safe for the road. Understanding the categorisation of defects and your responsibilities post-failure is paramount. Equally important is knowing your rights and the avenues available should you need to correct an error on your official MOT record. The DVSA provides a clear process for rectification of such mistakes, underpinned by robust data protection policies. By following the correct procedures, you can ensure your vehicle is compliant and its official record is accurate, giving you peace of mind on every journey.
