What Happens If Your Car Fails Its MOT?
Encountering an MOT failure can feel like a setback, but it's a standard part of ensuring road safety for all vehicles. The MOT test, a mandatory annual inspection for cars over three years old, checks that your vehicle meets roadworthiness and environmental standards. If it doesn't pass, you'll receive a 'refusal of an MOT certificate' detailing the reasons for failure. These reasons fall into two categories: 'dangerous' defects, which mean the car cannot be driven until repaired, and 'major' defects, which also require immediate attention but might allow limited use under specific conditions.
The key immediate question following a failure often revolves around the next steps, particularly regarding how long you have to rectify the issues and get your vehicle re-examined. It's not simply a case of booking another test immediately; the specifics of where and when you can do this depend on the circumstances of the initial test and the repairs undertaken. Understanding these nuances is vital to avoid unnecessary delays or even legal complications.
When your vehicle requires an MOT retest, the duration you have to complete this depends crucially on whether the car is taken back to the original testing station or a different one, and whether it can be driven on the road before the retest. For 'major' defects, most vehicles can be driven to a pre-arranged appointment for a retest at the original test centre. However, 'dangerous' defects mean the car must not be driven until repairs are completed. In such cases, you'll likely need to arrange for the vehicle to be recovered to a garage for repairs and then to a test centre.
The critical factor determining the timeframe for your MOT retest is the ability to drive the vehicle. If the car is roadworthy enough to be driven, and it's taken back to the same garage that conducted the original test within one working day, a partial retest might be possible. This is often quicker and cheaper. However, if the car is deemed undrivable, or if you choose to have repairs done elsewhere or wait longer than a working day, a full MOT test will be required again, along with the associated full fee.
The urgency of repairs cannot be overstated, as driving an unroadworthy vehicle carries significant risks and penalties.
MOT Retest Timelines: When and Where?
The clock starts ticking the moment your car fails its MOT. However, the specific rules about 'how long to retest MOT' are tied to where and when you present the vehicle for its subsequent inspection. For most drivers, the most straightforward approach is to return the vehicle to the same MOT test centre where it failed. This often allows for a partial retest, focusing only on the items that failed, and can usually be completed more quickly and at a reduced cost.
There are specific conditions under which a partial retest is permitted. Crucially, the vehicle must be returned to the same test centre within 10 working days of the original test date. If you miss this 10-day window, or if you take the vehicle to a different MOT centre, you will have to pay for a full, standard MOT test again. This is why planning and understanding the requirements beforehand is so important. The garage will typically advise you on the best course of action based on your vehicle's failure points.
If your vehicle has failed due to 'dangerous' defects, it must not be driven on public roads until those issues are fixed. In this scenario, you'll need to arrange for the vehicle to be transported, either for repair or directly to an MOT test centre. The 10-working-day window for a partial retest still applies if you can get it to the original test centre. However, if the repairs are extensive or require you to go elsewhere, be prepared for a full test.
The DVSA (Driver and Vehicle Standards Agency) sets these guidelines to ensure all vehicles on the road are safe. A partial retest is designed to confirm that the specific faults identified have been corrected, rather than re-evaluating the entire vehicle. For example, if only your headlights were found to be misaligned, a partial retest would only check the headlights. If other issues were flagged as 'major' but not 'dangerous', they would also need to be checked again as part of the retest process.
Plan your repairs and retest appointment strategically; returning to the original test centre within 10 working days is often the most efficient route for a partial retest.
What Counts as a Working Day?
It's important to clarify what constitutes a 'working day' in this context. Typically, working days are Monday to Friday, excluding public holidays. Therefore, if your car fails on a Friday, the following Monday would be the first working day in your 10-day allowance. This detail can be critical, especially if your MOT expiry date is approaching rapidly.
The Option of a Full MOT Retest
While a partial retest is often preferred, there are times when a full MOT test is necessary or chosen. This happens if: the vehicle is not presented for retest within 10 working days of the original test; the vehicle is taken to a different test centre; or if the original test centre deems the repairs so extensive that a full re-evaluation is required. In these situations, the full standard MOT fee will apply, and the entire vehicle will be tested again according to the current MOT test guidelines.
The Cost and Duration of an MOT Retest
The financial and temporal aspects of an MOT retest are significant considerations for vehicle owners. Understanding how long to retest MOT and what it might cost can help budget for unexpected failures. Generally, a partial retest, conducted at the same centre within the 10-working-day window, is considerably cheaper than a full MOT. Many test centres offer a free partial retest if the vehicle is left with them for the repairs and the subsequent retest. If you take the vehicle elsewhere for repairs and bring it back for the partial retest, there might be a reduced fee, but this varies by test centre.
The duration of a partial retest is typically much shorter than a full test. Since only specific items are being checked, it might take anywhere from 15 minutes to an hour, depending on the complexity of the original failure and the efficiency of the test centre. This speed is a major incentive to use the original test centre. If, however, a full MOT test is required again, you should expect the full testing duration, which usually takes around 45 minutes to an hour, plus any waiting time.
The fee structure for a partial retest is not legally capped like the maximum charge for a full MOT; it's at the discretion of the test centre.
Understanding Fees and Test Centre Policies
The maximum fee for a standard MOT test is set by the government, but there is no such cap for partial retests. This means that while many garages offer competitive pricing or even free partial retests (especially if you opt for their repair services), others may charge. It's always wise to clarify the cost of a partial retest when booking, especially if you've had repairs done elsewhere. Some garages might charge a nominal fee for the retest itself, while others might include it in the cost of repairs.
When Repairs Take Longer
Sometimes, the necessary repairs for an MOT failure can be extensive and take several days to complete. If your vehicle is left at the test centre for repairs, the 10-working-day window for a partial retest usually starts from the completion of the repairs, provided the vehicle is then retested promptly. However, if the repairs take longer than 10 working days, or if you collect the car and bring it back later, a full MOT test will likely be needed again. Always communicate clearly with your chosen garage about expected repair times and how this affects your retest.
Always get a written quote for repairs and confirm the retest fee with the test centre before authorising work.
Driving After an MOT Failure: What You Need to Know
A common point of confusion after an MOT failure is whether the vehicle can still be driven. The rules depend entirely on the severity of the defects identified during the test. If your car fails its MOT due to 'dangerous' defects, it is illegal to drive it on public roads. This classification means the vehicle poses an immediate risk to the driver, passengers, or other road users. The only exception is driving it to a pre-booked appointment for repair or to a pre-booked MOT retest, but this itself requires careful consideration and may necessitate recovery.
For vehicles with 'major' defects (but no 'dangerous' ones), the situation is slightly different. Your car can usually be driven if it has a valid MOT certificate that has not yet expired. However, it is strongly advised to get the repairs done as soon as possible. Driving a vehicle with known major defects, even if legally permitted due to an unexpired MOT, can increase the risk of further damage, breakdowns, and accidents. It also means that if you are stopped by the police and the defects are apparent, you could still face penalties.
The expiry date on your current MOT certificate is key; if it's still valid, you can typically drive the car to a pre-arranged retest, provided no dangerous defects were noted.
The Role of the MOT Certificate
Your current MOT certificate is valid until its expiry date, even if the vehicle fails its MOT on the day it's tested. This means you can legally continue to drive your vehicle until that expiry date, provided no 'dangerous' defects were found. However, the purpose of the MOT is to ensure roadworthiness, so delaying repairs on 'major' defects is ill-advised. Once the current certificate expires, and if the vehicle has not passed a new MOT, it is illegal to drive it on public roads. This is why understanding the retest process and getting it done promptly is crucial.
When is a Full New MOT Required?
A full new MOT test is required in several scenarios beyond the standard failure and retest. For instance, if you're selling a car that has failed its MOT, the buyer will need assurance that it will pass. You may choose to have it repaired and retested, or the buyer might accept it as-is, with the understanding they will handle the repairs and MOT. Furthermore, if a vehicle's MOT has expired and it has been off the road (e.g., SORNed), you'll need to get it repaired and pass a full MOT test before driving it again. This is also relevant for new cars; they typically need their first MOT test when they are three years old, and subsequent tests annually. If a new car fails its first MOT, the retest procedures apply just as they would for an older vehicle.
Electric Car MOTs: Differences and Retest Considerations
The automotive landscape is evolving, and with the rise of electric vehicles (EVs), there are specific considerations for their MOT tests. While the core principles of roadworthiness remain the same, certain components unique to EVs are now part of the inspection. For example, the battery and its management system are critical. Consequently, understanding how long to retest an MOT for an EV involves the same principles as for internal combustion engine vehicles, but the failure points might differ.
Currently, the MOT test for electric cars covers aspects such as brakes, tyres, lights, steering, suspension, and wipers, much like traditional cars. However, specific EV components like the high-voltage battery, charging ports, and electric motors are also subject to inspection for safety and security. Failures related to these components will require specific EV expertise for repair. The general timelines for retesting, including the 10-working-day window for a partial retest at the original centre, still apply, provided the vehicle can be driven to the appointment.
The fundamental rules for MOT retests – the 10-day window and the distinction between partial and full tests – apply equally to electric vehicles.
Specific EV MOT Failure Points
While mechanical failures common to all vehicles (like worn brake pads or tyre damage) will lead to an MOT failure for an EV, there are EV-specific checks. For instance, the integrity of the high-voltage battery enclosure is crucial; any damage or corrosion that compromises its safety would likely result in a failure. Similarly, the charging socket must be secure and free from damage. Electrical connections must be properly insulated and secured to prevent hazards. While the MOT test guidelines are continuously updated, the underlying principle is that any part of the vehicle that could pose a safety risk must be in good condition.
If an electric car fails its MOT, the process for retesting is identical to that of a petrol or diesel car. If the failure points are minor and do not make the vehicle dangerous to drive, it can be taken back to the same test centre within 10 working days for a partial retest. If it's deemed dangerous to drive, or if the 10-day window is missed, a full MOT test will be required again. The garage undertaking the repairs will need to have the appropriate knowledge and equipment for handling EV high-voltage systems.
When booking an EV for an MOT retest after repairs, confirm the test centre has technicians qualified to inspect EV-specific components.
