If your car fails an early MOT test, you might still be able to drive it depending on the circumstances. In this guide, we explain when it’s legal, such as if your current MOT is still valid and the car is roadworthy, and when it’s not, so you can avoid fines and points on your licence.

Assuming your car is older than three years, you need to take it to a garage once per year for an MOT test. This is the annual test that verifies your car meets the government's minimum safety and environmental standards.
While your MOT certificate is valid for a whole year, you can get the test done up to a month (minus a day) before its expiry and still keep the same renewal date.
Failing an MOT test is frustrating and inconvenient, especially if you rely on your car for daily transportation.
If you fail the MOT early, you may or may not be able to continue driving your vehicle until your current certificate expires. It all depends on the severity of the failure and whether it poses a risk to you or other road users.
When your car fails its MOT before the due date, here's what to expect and the steps you should take going forward:
When your car fails its MOT, the test result will indicate whether the issues are classified as 'dangerous' or 'major'. 'Minor' defects will not cause an MOT failure.
Whether you can drive after the MOT test depends on whether you have major or dangerous defects.
An example of a major defect would be a faulty shock absorber, exhaust emissions exceeding the legal limits, or windscreen wipers/washers not working properly.
A dangerous defect might be severely worn brake pads or discs, tyres with tread depth below the legal limit, or faulty/non-functional headlights, brake lights, or indicators.
If your current MOT certificate is still valid, you can continue to drive your car until the expiry date, provided the faults are not classified as dangerous.
This is one of the main advantages of scheduling an early MOT, if you need to fix something, you can take it to the garage of your choice, on your own time.
If your test reveals dangerous faults, you are not legally allowed to drive the car, even if your current MOT is still valid.
Even if you can legally drive, you should arrange to have the necessary repairs done as soon as possible. Failing the MOT test means your car is no longer roadworthy. Not to mention, a failure indicates a problem that will only get worse with time.
If you only have major faults, you can either take your car to a separate garage for repairs or have it done at the MOT test centre.
Since you cannot legally drive a vehicle with dangerous defects, your only option is to have the MOT garage handle the repairs (unless you want to deal with the hassle and expense of having it towed).
MOT retesting can work in a couple of different ways, depending on whether you got the initial test and the repairs done at the same garage, and how long you choose to drive the car before retesting.
If you choose to have your repairs done by the MOT garage, they will typically offer a free partial retest within 10 working days.
As long as you bring the car back within that timeframe, you shouldn't have to pay for another test. And you shouldn't have to go through the whole process again, just the points of failure.
If you get the repairs done at a garage different from the one that performed the MOT test, you might have to pay for a retest at the original centre.
This, of course, depends on the MOT garage's policy. But these are the general guidelines that most follow.
Retesting at a different garage
If you don't choose the original MOT garage for your repairs, you will have to pay for the whole thing all over again (which is up to up to £54.85). The new garage will have no way of verifying the previous test results, so they must perform a new one.
Note: You won't qualify for a partial retest if you have several different failure points that impact different systems in the car, especially if those defects are classified as dangerous.
If you took an early MOT and failed, you can legally drive your car up to the expiry date of your current certificate, as long as you are not dealing with dangerous defects. In that case, you have to get repairs and pass a retest before driving again.
For example, if you got your test done on 1 March and your expiry date is 14 March, you have two weeks to get the repairs and retest done before you run into trouble with the law for driving the vehicle.
Early or not, the fact of the matter is you failed your MOT test. You're driving a vehicle that the authorities have deemed unsafe for yourself and others. That can land you in hot water; there are legal risks that come with driving after an MOT failure.
The exception to the rule: You are allowed to drive your car to a garage for repairs or to a pre-booked MOT test, so long as the faults were not classified as dangerous at your last test.
Driving a car that has failed its MOT may also affect your insurance. If you are involved in an accident, your insurance may not cover you if the car was deemed unsafe.
Here's what you need to know:
The above mentioned exception applies here, too, though. If you're in an accident but you're on the way to or from a garage for repairs or retesting, your insurance policy should still cover you.
Even if you don't have dangerous defects, the smart and safe thing to do, regardless of whether your current MOT certificate has expired or not, is to take care of those repairs as soon as possible. Failing means your car has a serious problem that is affecting its safety and roadworthiness.
It's also a good idea to get the repairs done at the same garage. Since you're already there, they can get straight to work on your car. And since they've already done the first test, the subsequent partial one will be much faster (not to mention, free).
Since you have time, though, you can multiple quotes to find the best price for your repairs. You can get the repairs done at a different garage if you find a better deal.

If your car has failed its MOT due to dangerous faults, it is definitely not safe to drive. These faults pose an immediate risk to road safety, and driving the car could lead to severe accidents or further damage.
Major defects don't necessarily guarantee your car is safe to drive, though. They just don't legally prohibit you from doing so.
If your car has major defects, ask the MOT test centre for advice before leaving.
If your car fails its MOT early, you generally do not need to notify any specific authorities. All you have to do is:
If you believe the MOT failure was unjustified, however, you can appeal the result by submitting a VT17 form to the DVSA. This must be done within 14 days of the test.
Since everything is digitised these days, you don't need to bring much on the day of the test. Just your car and the following items:
The garage will have all other necessary documentation on file, including previous MOT certificates and test results.
Failing an MOT test is not the end of the world. It's actually quite common; millions of vehicles fail their initial MOT test every year.
The key is to address the issues and get your car roadworthy as soon as possible. Driving without a valid certificate will lead to legal troubles, so it's not worth waiting.
Remember that driving a car with defects also poses risks for insurance coverage in case of accidents. So take care of repairs immediately, even if you have time left on your current MOT certificate. It's always better to be safe than sorry.
