Click here for a complete list of common MOT failures broken down by make,model and year of vehicles
As we can see the biggest reason for failure was lighting.
A blown bulb! How hard is it to change a bulb?
Tyres can be inspected easily to avoid the second biggest reason for failure. Cracked windscreens are again easily checked and most fully comprehensive insurances cover windscreen repair and replacement. If everyone checked these items before their MOT test in 2007 then 547,151 failures could have been avoided (thats over 65%).
Two more startling reasons where Reg Plates and Road Wheels. Standard Registration plates will not fail an MOT but customise your own and your in for trouble. Same goes for wheels. They must be the standard wheels for the car. The road holding, speedometer and gearing etc. are all designed around a specific sized wheel and changing this can cause MOT failures aswell as damage. Again both items are easily checked.
Some of the other reasons may get a little more technical but there is no reason why we cannot attempt them ourselves in an effort to save money and time off the road.
Below are the checks that you can make yourself before putting your vehicle through its MOT. You do have to do every check but we would suggest doing the tests that have the highest failure rates first ie bulbs etc.. The top 3 reason for MOT failures are the 3 easiest tests to carry out yourself.
Checks 1-6 can be carried out sat in the drivers seat
Checks 7-12 are carried out by inspection ot the outside of your vehicle
Checks 13-18 Need your wheels to be off the ground and free to rotate.
Checks 19 - 20 Are exhaust and emission checks
