How to Prevent MOT Failure


Failing your MOT can be a major inconvenience for all motorists; it means more time off the road for your vehicle and, in some cases, it can cost you a lot of money. However, there are ways that you can avoid the dreaded failure and ensure that you and your vehicle can get back on the road as soon as possible. This article will detail some of the steps you can take to help increase your chances of passing your MOT.


Dead bulbs in vehicles are responsible for almost 20% of MOT failures. When you consider how simple it is to change a light bulb on a car, failing your MOT for having a dead bulb is a totally avoidable problem. Get a friend to check your lights or park close to a wall to see if they’re working or not in the reflection.

Wheels & Tyres

The legal minimum tyre tread depth for cars and LCVs is 1.6mm across ¾ off the tyre’s width. A good way to check to see if you tread depth meets the legal requirement is by using a 20 pence piece: simply place the coin vertically in the deepest tread on the tyre, and if you can still see the outer ring of the coin (where the date is) then your tyres do not have enough tread. Check your tyre for splits and cuts, particularly in the sidewalls of your tyres, and also ensure that your two front tyres and two rear tyres are the same size as each other.


Ensure that your wiper blades are not excessively worn. Test them by spraying your windscreen with wiper fluid as you would normally and see how well they clean your windscreen.

Washer Jets

Check your washer jets to see if they are blocked or not. Top up the wiper fluid and see if the jets spray the fluid as they should. If not, they are relatively simple to fix: just use a pin to clear the blockage.


There are a few checks you can carry out yourself on your brakes; ensure that the rubber on your vehicle’s pedals isn’t worn away, check that your ABS works (if it does, the warning light will go out after your car starts) and your handbrake should also be able to hold the car on a hill.


While there are many checks that you can carry out yourself on your vehicle, the most effective way to ensure you pass your MOT is to have your vehicle serviced shortly before the test. The garage can conduct more detailed tests, and any faults or issues that are discovered can be rectified before your MOT, possibly saving you time and money.
