There are many ways in which you can try and help your car get through an MOT test. Below are a few items to check before taking the care in. Ideally these should be checked at least a week before the test date to ensure you have time to address any issues:
Tyres – Check that all tyres have a tread depth of at least 1.6mm right the way around and across the central three-quarters of the pattern. A quick way to check is to insert a 20p piece into one of the tread grooves. If the outer edge of the coin is completely obscured then the tread depth is sufficient. Tyres also need to be correctly inflated as a flat tyre will fail an MOT.
Lights – All of your lights (including head lights, parking lights, reversing lights, indicators and registration plate bulbs) need to be the right colour and in good working order for your car to pass the MOT test. A simply check around the car can allow you to replace any bulbs that are not working.
Window wipers – The wipers and washers should work well enough to allow you a clear view of the road. If the jets are not working at all or not working as well as they should then this is a fail. Also the wipers may need to be replaced if they are leaving a smear on the screen rather than clearing it.
