The new Mot rules 2018

The new MOT rules 2018

The new rules will categorise defects as either: dangerous, major or minor. With the old MOT your vehicle received a pass, a pass with some advisory faults, or a fail.

New MOT categories

Pass – Your vehicle passes and meets the legal standard.

Advisory – Your vehicle passes but there is an issue that you’ll need to keep an eye on, and repair if it gets worse.

Minor – Your vehicles passes but has an issue that needs to be corrected as soon as possible. If you don’t get it fixed it could get much worse.

Major – Your vehicle fails if it has a major fault. The repair needs to be made as soon as possible.

Dangerous – Your vehicle fails if it has a dangerous fault. The vehicle cannot be driven until the fault has been repaired.

The difference between Dangerous and Major MOT faults - and when you can drive 

In short, with a dangerous fault you cannot drive your car.

With a major fault, you might still be able to drive your car if it is still roadworthy.

Remember: You can have your MOT carried out up to a month before your old MOT is due to run out, and the anniversary date will still be one year after the old certificate date – effectively meaning the MOT certificate will last for 13 months.

If your vehicle fails the MOT before your old MOT certificate expires:

• You can’t drive it with dangerous faults. These need to be repaired first. If you use a vehicle with a dangerous fault you can be fined £2,500, be banned from driving and get three points on your license. This is because your vehicle is automatically recorded as no longer road legal on the UK’s digital vehicle database, so the authorities will know about its condition.

• You can drive your vehicle with a major fault if your old MOT is still valid, because you took your vehicle in for MOT early. But your vehicle does have faults that may make it unroadworthy, and if stopped by the police you could be prosecuted.

If your vehicle fails the MOT on the same day as your MOT certificate expires:

• You may take your vehicle to get it repaired after is has failed its MOT test, but you cannot use a vehicle with dangerous faults, or you can be fined £2,500, be banned from driving and get three penalty points. If it has major faults you can drive it to get repairs, but if the police stop and deem it unroadworthy, you could be prosecuted.

• You can drive your vehicle to a test station for an MOT test booked in advance, although you would have needed to have any faults repaired so that it is roadworthy and of course, without repairs, it is unlikely to pass an MOT. Again, dangerous faults uncorrected make it illegal to use on the road.

What to do if your vehicle has a dangerous fault

If your MOT results show a dangerous fault, you won’t be able to drive it anywhere. This doesn’t mean you have to have the repairs carried out at the garage that performed the MOT though.

You should get a quote for the work that needs to be done at the garage that carried out your MOT, and then find some quotes from some other garages. You might find, even with a towing fee, you can get it fixed for less.


If your vehicle fails an MOT and you leave it with the test centre for repair, you’ll have a partial retest. As long as this is done within 10 working days of failing the MOT and will be free.

If you take your vehicle away for repairs and return it before the end of the next working day, the test is normally free. Whether it’s free or not depends on which parts are retested. If you return within 10 working days to the same test centre for a partial retest, you’ll get charged a lower fee, but it may not be free.
