According to the Drivers and Vehicle Standards Agency (DVSA) the top three items to fail an MOT are:
1. Headlight Aim
2. Tyre Tread Depth
3. Windscreen wipers
Tyre tread depth is easy to check with a 20p coin. If you can see the outer rim of the coin when you insert into the tyre grooves, they may need changing. Visit any Good Garage Scheme member garage to check if you are unsure.
Windscreen wipers do a tremendous amount of work and may need changing. This is something you can easily check and replace should they look worn. You can probably tell if they are not clearing the screen as smoothly as possible in bad weather but best to run your hand along to edge to check for cracks or wear.
Other items you can check before your test are seat belts, fluids in the car and bodywork.
Remember, an MOT is not a service. If you are looking to buy a car that has recently passed an MOT, ensure you also check when it was last serviced.
