Almost half of all MOT failures are for simple things that could have been checked and fixed before the test. In our MOT checklist guide we’re going to provide some practical things that every driver can do to give their car the best chance of passing first time.
Don’t worry if you’re not a mechanic, most of these checks can be done at home with some basic tools and a bit of time. If you ever get stuck, Halfords is here to help.
Preparing for your MOT
Checking over your vehicle before its MOT could mean the difference between a pass and a fail, so it's definitely worth doing.

12 essential pre-MOT checks
Our expert technicians have listed 12 essential pre-MOT checks that anyone should be able to perform. Work your way through each of the steps to identify any faults and then fix them.
Taking some time before an MOT could help you avoid the expense and inconvenience of an MOT failure.
Test the handbrake and ensure it works correctly. If you have to pull the lever a long way up or it clicks too many times the cable may need adjustment. Get this checked out before your MOT.
Check all seat belts for fraying, cuts or other signs of damage. The front seats must be securely attached and the backrests must lock in the upright position.
Check the steering wheel does not feel too loose. If it does this could indicate a wear in the linkage that could cause an MOT failure.
Lift the bonnet and check the brake fluid level. Press the brake pedal and make sure that it doesn't feel spongy. If it does, there may be air in the hydraulic system which will need to be removed by bleeding. Your brakes are a crucial part of your car so never take any chances. If you’re worried you can arrange a free brake check at Halfords.
Check that your wing mirror and rear-view mirror are in good condition, and that you can adjust them if you need to. If they're broken or cracked, be sure to replace the mirror glass or the entire mirror.
There shouldn't be any cracks or chips in the windscreen within the driver's field of view. If you spot a crack, chip or split, get it fixed ASAP. Some insurance companies will pay for your windscreen to be repaired if the chip is small enough.
Check the windscreen washers and wiper blades work. Replace worn wiper blades and top up your screen wash if it's a bit low. Signs your windscreen wipers may be on the way out include squeaking while they’re working or failing to clear the windscreen of water.
Check your horn works by giving it a beep. (Do this away from traffic and pedestrians as it could shock them.)
Double check that your number plates are in good condition and legible. Cracked, damaged or obscured registration plates can cause an MOT failure.
You’ll need two people for this one. Sit in the car’s cab and turn on your lights. Have someone walk around your vehicle and check everything, including headlights, brake lights, fog lights and indicators, are working as they should.
If any of your lights aren't working, replace the bulbs or check the wiring to make sure there aren't any loose connections. At Halfords, we stock a huge selection of bulbs for all makes and models and can even fit replacements while you wait. The average car bulb costs less than £10, so there’s no reason for not replacing them when needed. We recommend keeping a set of spares in your boot for emergencies.
Use a tread depth gauge to check how much tread there is on each tyre. The legal minimum is 1.6mm - although it's better to fit new tyres well before they get this low. Driving with tyre tread below 1.6mm isn’t just dangerous, it’s illegal – with a penalty of 3-points for each tyre that’s under the limit.
You’ll need to take care with this one to avoid burning yourself. You can check the exhaust by starting the engine and holding a clean cloth over the tailpipe. You’ll be able to hear if the system is leaking. If you’re worried about your exhaust, it’s better to drop into your nearest Halfords where we can help you.
