Understanding Your MOT Failure and Retest Options
If your vehicle has failed its MOT, the most immediate concern is understanding what happens next, particularly regarding a mot retest fail. Upon failing, you will receive a VT30 report detailing the reasons for the failure. This report categorises issues into 'dangerous', 'major', or 'advisory' faults. Dangerous faults mean the vehicle must not be driven until repaired, while major faults require immediate repair to pass. Advisory faults are not reasons for failure but need attention soon.
- Receive a VT30 report detailing faults.
- Dangerous faults prevent driving the vehicle.
- Major faults require immediate repair.
- Advisories are recommendations, not failures.
Your options following a mot retest fail depend on whether you leave the testing centre. If you can drive the vehicle away, you have 10 working days to get it repaired and retested at the same garage without a full retest fee, provided the repairs are minor or only items with advisories are corrected. If the repairs are more extensive or you leave the premises, you may incur a full MOT fee for the subsequent test. For dangerous faults, you must arrange for the vehicle to be towed or trailered to a repair shop, as driving it is illegal and unsafe.
When You Can Drive After a MOT Failure
You are legally permitted to drive your vehicle to a pre-arranged MOT retest or to a place of repair if it has failed its MOT, provided the failure was not due to a 'dangerous' fault. This exemption applies even if your MOT certificate has expired. However, your vehicle must be roadworthy. If it has failed due to a dangerous defect, it cannot be driven on public roads at all until those specific issues are rectified and it passes a retest. Always ensure you have adequate insurance, as driving an uninsured vehicle, even to a pre-booked MOT, is illegal.
The MOT Retest Schedule
The timing of your MOT retest is crucial. If you leave the vehicle at the testing station for repair and retest, the retest is typically carried out free of charge or at a significantly reduced rate, provided it is completed within one working day of the original test. If you take the vehicle away for repairs elsewhere, you have up to 10 working days to return it to the *same* garage for a partial retest. After 10 working days, or if you take it to a different garage, you will likely have to pay for a full MOT test again.
The primary advantage of leaving the car at the test centre for repairs is the cost of the retest.
What Constitutes a 'Dodgy MOT Test'?
A 'dodgy MOT test' is one where the tester has either unfairly failed a vehicle or passed one that should have failed. This can happen if the tester is not following the DVSA's (Driver and Vehicle Standards Agency) strict guidelines or, in rare cases, if there's an intent to gain financially. Reasons for suspicion might include a failure for a very minor or non-existent issue, or passing a vehicle with obvious safety defects. If you suspect your vehicle was subject to a dodgy MOT test, you have the right to complain to the garage and the DVSA. The DVSA investigates all such complaints and can take action against authorised examiners who fail to follow procedures.
Common Reasons for MOT Failure and How to Avoid Them
Many MOT failures are preventable with basic vehicle maintenance. Understanding the most frequent reasons for failure can help you proactively address potential issues before your car reaches the testing bay, thereby avoiding a mot retest fail. The MOT testing manual class 4, for example, outlines specific areas tested, and common pitfalls exist across all vehicle classes.
Tyres, Wheels, and Brakes
Tyres are a significant cause of MOT failure. Inspectors check for tread depth (below 1.6mm), cuts, bulges, or signs of wear on the sidewalls. Ensuring your tyres are properly inflated and have sufficient tread is vital. Similarly, brakes are a critical safety component. Examiners will check brake pads and discs for wear, the condition of brake lines for leaks or corrosion, and the effectiveness of the braking system itself. Issues like spongy brake pedals or warning lights on the dashboard are immediate red flags.
Lights and Signalling
All lights on your vehicle must be functional and correctly coloured. This includes headlights (dipped and main beam), taillights, brake lights, indicators, and hazard lights. A blown bulb, cracked lens, or incorrectly coloured light (e.g., white rear light) will result in a failure. Ensure all signals are clear and visible, especially during adverse weather conditions.
Visibility Issues: Windscreens and Wipers
A clear view of the road is paramount. A windscreen mot failure can occur if there is damage, such as cracks or chips, in the driver's direct line of sight that is larger than 10mm. Damage outside this area larger than 40mm can also cause a fail. Similarly, windscreen wipers must be in good condition and effectively clear the screen. If they smear or leave patches, they may need replacing. Washer fluid levels should also be adequate.
Structural Integrity and Exhaust System
Corrosion is a common culprit for structural failures. The MOT test checks for excessive rust or damage to the vehicle's chassis, body panels, and suspension components. While minor surface rust might be an advisory, significant corrosion that weakens the structure is a fail. The exhaust system is also inspected for leaks, excessive noise, or poor security, as these can indicate serious problems and affect emissions.
Regular checks of your tyres, lights, and windscreen can prevent most common MOT failures.
Emissions Test Failures
For modern vehicles, passing the emissions test is essential. This test measures the pollutants emitted by your car's exhaust. Failures can be due to faulty catalytic converters, exhaust leaks, or engine management issues leading to incorrect fuel-air mixtures. Ensuring your engine is running correctly, servicing your vehicle regularly, and using the correct grade of fuel can help prevent emissions failures.
What to Do After Failing Your MOT: Your Options
Receiving news of a mot retest fail can be disheartening, but it's not the end of the road for your vehicle. You have several avenues to pursue, primarily revolving around repair and retesting. The key is to act promptly and systematically to minimise disruption and cost.
Immediate Repairs at the Test Centre
If the MOT test results in a failure and the garage offers repair services, you can opt to have the necessary work done on-site. As mentioned, if the vehicle is retested within one working day, the retest is usually complimentary or very low cost. This is often the most convenient option, especially for minor repairs, as the testers are already familiar with the faults identified. They can quickly rectify the issues and perform the retest, hopefully leading to a pass.
Taking the Vehicle Elsewhere for Repairs
You are not obliged to have repairs done at the original testing station. You can take your vehicle home or to another garage of your choice for repairs. If you do this, remember that you have up to 10 working days to bring the vehicle back to the *same* test centre for a partial retest. This retest typically covers only the items that failed. If you fail to return within 10 working days, or if you go to a different test centre, you will have to pay for a full, new MOT test.
The Importance of the VT30 Report
The VT30 report is your essential document after failing an MOT. It lists every defect found and categorises it as 'dangerous', 'major', or 'advisory'. 'Dangerous' defects mean the vehicle must not be driven on public roads until repaired. 'Major' defects require repair for the vehicle to pass the MOT. Advisory items are noted as things to watch out for and may become failures at a future test. Keep this report safe, as it details exactly what needs to be done. Understanding this report is the first step in preparing for a successful mot retest.
Your VT30 report is the definitive list of what needs fixing.
When is the First MOT Due on a New Car?
For a brand-new car, the first MOT test is generally due three years after its registration date. This means you do not need to worry about an MOT test for the first three years of ownership. After this initial test, subsequent MOTs will be required annually. This rule applies across the UK for most passenger vehicles.
Driving a SORN Car to an MOT
A vehicle that is declared SORN (Statutory Off Road Notification) is not legally allowed on public roads. However, there is an exception if you need to drive it to a pre-arranged MOT appointment. You must drive it directly to the test centre. If the vehicle fails the MOT and the failure is not a 'dangerous' fault, you can then drive it home or to a repair shop, again directly. It is crucial to have proof of the pre-booked MOT appointment. While you might assume you can drive a SORN car to an MOT, you must still have valid insurance covering you for that journey. Driving without insurance is illegal, even for this specific purpose.
Preparing for Your MOT Retest: What to Check
A successful mot retest hinges on meticulous preparation. Once you have identified the reasons for failure from your VT30 report and arranged for repairs, it's time to focus on ensuring the vehicle is in optimal condition for its second chance. This stage is critical to avoid further expense and delays.
Reviewing the Repairs
After the repairs have been completed, take a moment to review them. If you had the work done at the original test centre, they will have a good understanding of what was needed. If you chose a different garage, ensure they have addressed all the points raised on the VT30 report. Ask for a clear explanation of the work carried out and keep all receipts for parts and labour. This documentation can be useful and shows due diligence.
Pre-Retest Checks: Your Own Inspection
Before you drive the vehicle back for its retest, perform your own quick inspection. Check that all the lights are working, including brake lights and indicators. Ensure tyres are correctly inflated and have adequate tread. Test your windscreen wipers and washer fluid. Give the bodywork a visual once-over for any new, obvious damage that might have occurred during repairs or transit. These simple checks can catch last-minute issues.
Understanding Fair Test MOT Practices
A fair test MOT means the examiner assesses your vehicle against the DVSA's published standards without bias. If you feel the original test was not a fair test MOT, or if you are concerned about the repairs, you can request a second opinion or file a complaint. DVSA-authorised testers are trained to be objective. If a repair shop seems hesitant to explain the repairs or shows a lack of transparency, it might be worth seeking an alternative service provider for peace of mind.
Double-checking the repairs against the VT30 report is crucial before the retest.
The Role of the AA MOT Test
Organisations like the AA offer MOT testing services. An AA MOT test is conducted by trained technicians adhering to strict DVSA guidelines. If you're concerned about the fairness of a test or the thoroughness of repairs, using a reputable service provider like the AA for your initial test or retest can offer reassurance. They are committed to providing an accurate assessment of your vehicle's roadworthiness.
What If My Car Fails a 'Fair Test' Again?
If your car fails a 'fair test' MOT again, it means the initial repairs were insufficient or another issue has arisen. Carefully review the VT30 report from the second failure. Compare it with the previous one. Are the faults the same, or are there new ones? This information is vital for your mechanic to correctly diagnose and fix the underlying problems. It might be worth seeking advice from a different mechanic if you suspect the previous repair attempts were not successful.
When Can You Drive a SORN Car to MOT Without Insurance?
This is a critical question that often causes confusion, especially after a mot retest fail. Generally, a vehicle declared SORN is not permitted on public roads. Driving a SORN vehicle on the road without valid insurance is illegal and carries significant penalties. However, there is a specific, limited exception.
The SORN Exemption for MOT
You are legally permitted to drive a SORN vehicle to a pre-arranged MOT appointment. This is the only instance where a SORN vehicle can be used on public roads. You must drive directly to the test centre. If the vehicle passes, you can drive it away. If it fails, and the failure is not categorised as 'dangerous', you can also drive it away to a place of repair or your home, provided you are taking it directly there.
The SORN exemption is strictly for direct travel to and from a MOT appointment.
Insurance Requirements for SORN Vehicles
Crucially, even when using the SORN exemption to attend an MOT test, you **must** still have valid insurance that covers you for that specific journey. This means you need at least third-party insurance. Driving without insurance, even for the sole purpose of attending an MOT, is a serious offence. If you are stopped by the police, you will need to demonstrate that you were travelling directly to or from a pre-booked MOT test and that you had the appropriate insurance cover for that trip.
What Constitutes 'Direct Travel'?
'Direct travel' means proceeding straight to the test centre and then straight home or to a repair garage. Any detours or stops for personal errands would invalidate this exemption, making the vehicle uninsured and illegally on the road. The DVLA expects this journey to be solely for the purpose of the MOT test and subsequent return.
Consequences of Incorrect Use
Using a SORN vehicle on the road outside of this specific MOT exemption, or without the required insurance, can lead to fines, penalty points on your licence, and your vehicle being seized. It is vital to understand the limitations of this exemption to avoid legal trouble. If in doubt, it is always safer to arrange for the vehicle to be transported by trailer or recovery vehicle.
Navigating Bodywork and Chassis Issues in MOTs
Bodywork and chassis integrity are fundamental aspects of vehicle safety, and issues in these areas are common causes for MOT failure, especially for older vehicles. A thorough body mot test checks for structural soundness and the absence of hazards to other road users.
Corrosion and Structural Integrity
The MOT test places significant emphasis on the structural condition of the vehicle. Inspectors are trained to identify excessive corrosion. This isn't just about appearance; it's about how rust compromises the strength of key structural components like the chassis, suspension mounting points, subframes, and wheel arches. Areas that are considered critical for structural integrity include the vehicle's frame, floor pan, and sills. Even if a part doesn't look heavily rusted, if the tester finds corrosion that weakens its structure, it will likely fail. Surface rust might be noted as an advisory, but any deep pitting or material loss that affects strength is a major concern.
Specific Areas Checked
Testers will meticulously inspect specific areas: the chassis, especially around the suspension and engine mounts; the vehicle's floor, looking for holes or significant weakening; the sills (the structural beams along the base of the car doors); door pillars; and wheel arches. They will also check for any sharp edges or projections that could cause injury to pedestrians or cyclists, as these are also MOT fail items.
Structural corrosion is a primary reason for a vehicle to fail its body MOT test.
Modifications and Aftermarket Parts
Any modifications made to the bodywork, such as fitting a body kit, different bumpers, or altering the chassis, must be done to a safe standard. If modifications have compromised the vehicle's structural integrity or are insecure, they can lead to failure. Similarly, if aftermarket parts are used, they must be suitable and fitted correctly. The focus is always on maintaining the original safety standards or improving upon them without introducing new risks.
What About 'Advisory' Corrosion?
An 'advisory' note for corrosion means that while the rust present does not currently cause the vehicle to fail, it is something that the tester believes will require attention in the near future. This could be surface rust that hasn't yet compromised the metal's strength, or minor corrosion in a non-critical area. It's wise to address these advisories promptly, as they can worsen over time and become a reason for failure at a subsequent MOT.
Preparing for a Bodywork Retest
If your vehicle fails due to bodywork issues, the repairs often involve welding and structural reinforcement. This is skilled work. Ensure that any welding is carried out to a high standard and that the new metal used is appropriate for the structural needs. After repairs, the vehicle will need to be retested. If the repairs involved structural elements, the tester will be particularly vigilant to ensure the work is sound and safe, thereby avoiding another mot retest fail.
Advisory Notices and Future MOTs: What You Need to Know
Advisory notices on your MOT certificate are not failures in themselves, but they are important warnings about potential future problems. Understanding advisories is key to proactive vehicle maintenance and avoiding unexpected mot retest fail situations down the line.
What is an Advisory Notice?
An advisory notice is a recommendation from the MOT tester that a component or system is showing signs of wear or is close to failing but does not meet the criteria for a 'major' or 'dangerous' fault at the time of the test. For example, minor corrosion on a non-structural part, slightly worn suspension components, or a tyre with tread depth that is still legal but approaching the minimum might be listed as advisories. The 'fair test' ethos means that even items that are not failed must be noted if they are considered a potential issue.
Why Are Advisories Important?
Advisories are essentially a heads-up for you, the owner. They highlight items that are likely to need attention or repair before the next MOT test. Ignoring them can lead to those components deteriorating further, potentially causing a failure at your next inspection or, more importantly, leading to a breakdown or safety issue on the road. Regular vehicle maintenance, informed by these advisories, is crucial for keeping your car safe and roadworthy.
Treat advisories as essential maintenance pointers, not just optional suggestions.
Advisories vs. Failures
The distinction between an advisory and a failure is based on the strict criteria set out in the MOT testing manual. A failure means the vehicle does not meet the minimum legal standard for safety, roadworthiness, or emissions. An advisory means it *currently* does, but there's a risk. For example, a tyre with 3mm of tread might be an advisory, while a tyre with 1.5mm of tread would be a failure. Similarly, minor corrosion on a suspension mounting point might be an advisory, but if it significantly weakens the structure, it becomes a major fault.
Preparing for the Next MOT
When your next MOT is due, review any advisories from previous tests. If you had an advisory for, say, a worn brake pad, it's highly probable it will need replacing now. If you had an advisory for corrosion, check its progress. Proactively addressing these issues can save you the stress and cost of a mot retest fail. Many garages will offer to carry out these recommended repairs for you.
The 'Why are old cars MOT exempt' Query
The question of 'why are old cars MOT exempt' relates to a change in regulations. Vehicles that were registered before a certain date (historically, before 1960, but this has been updated) are exempt from the standard MOT test. The rationale is that these vehicles are generally driven less frequently and are considered to be of historical interest, with their owners often maintaining them to a high standard privately. However, this exemption does not mean they are exempt from road safety laws; owners are still responsible for ensuring their vehicle is roadworthy. This is different from standard MOT failures and retests.
Challenging an MOT Test Result
While most MOT tests are straightforward, there are occasions when a vehicle owner might believe the result was incorrect. If you believe your vehicle has been unfairly failed or unfairly passed, leading to a potential mot retest fail or an unsafe vehicle, there are formal channels to challenge the decision.
When to Challenge
You might consider challenging an MOT result if you have strong evidence that the test was not conducted according to DVSA guidelines, or if you believe the outcome is demonstrably wrong. This could be due to a failure on a component that is clearly in perfect working order, or a pass on a vehicle that has obvious, serious safety defects. Suspicion of a 'dodgy MOT test' is a primary reason to challenge.
The First Step: Speaking to the Garage
Your first course of action should always be to discuss your concerns directly with the manager of the MOT testing station. Present your case calmly and clearly, referring to specific parts of the VT30 report or your observations about the vehicle. They may be able to clarify the tester's decision or, if a genuine mistake was made, offer to rectify it. Sometimes, a misunderstanding can be resolved at this stage.
Direct communication with the garage manager is the essential first step.
Making a Formal Complaint to the DVSA
If you are not satisfied with the garage's response, you can make a formal complaint to the DVSA. You will need to provide them with as much information as possible: the vehicle's registration number, the date and time of the test, the name and address of the testing station, copies of the VT30 report and any receipts, and a detailed explanation of why you believe the test was incorrect. The DVSA will then investigate your complaint. This investigation may involve reviewing the tester's records, interviewing the tester, or even requesting the vehicle to be re-examined.
The Retest Process During a Challenge
If you are challenging a fail and the vehicle is still at the test centre, you generally cannot proceed with a retest until the dispute is resolved or you agree to have the repairs done and retested. If you've taken the vehicle away, and the DVSA agrees to investigate, they might arrange for an independent inspection. If the DVSA investigation finds the original test was flawed, they can instruct the original garage to retest the vehicle correctly, often free of charge. If the DVSA uphns the original test result, you will then need to follow the standard procedure for a mot retest, potentially at your own cost.
What is the AA MOT Test's Role?
As mentioned earlier, the AA MOT test is conducted to DVSA standards. If you have doubts about a test, you can choose to have your vehicle tested by a reputable provider like the AA. If you are undertaking a challenge, a report from an AA MOT test, or indeed any independent, qualified assessment, can serve as valuable evidence to support your claim that the original test was not a 'fair test MOT'.
