Why Your Car May Fail MOT Testing


MOT testing is as unavoidable as it is necessary to ensure that all vehicles on the road are safe and reliable for you to drive as this is a test designed not only for your safety but for the safety of others with whom you share the road. That said, many motorists fail to check on the many small details of their vehicles that may result in a failed test and since these issues are nearly always minor and easily fixed, the best action that you can take for yourself is to have your vehicle inspected prior to testing. Knowing the most common small repairs that may be done to avoid failing the test will save you a great deal of time and money in the long run and allow you to enjoy many additional years on the road in your favourite car.

Poorly-Adjusted Headlamps

The headlamps of your car should certainly not be so bright that other motorists assume that your main beams are always on and they should conversely not be so dim as to be all but useless after nightfall. One of the most common reasons why cars fail MOT testing, precisely 17%, is that they have badly-adjusted headlamps that are not within a safe range for driving during fog or the hours of the night. A trained mechanic will easily reset this problem and have you ready to get back on the road with headlamps that are the perfect brightness to see clearly without blinding other drivers as they pass you on the road.


Your tread depth is a serious issue and should always be at a certain depth to ensure not only your safety but the safety of other motorists, especially when you consider just how dangerous a bald tyre is when left on a vehicle. MOT in Cheltenham is a test that you cannot avoid taking each year but you may avoid taking the test more than once by ensuring that the tread depth of your tyres is always at the proper amount, 1.6mm at minimum. Many safety organisations go so far as to suggest 3mm as the minimum tread depth to avoid any drop in performance from your tyres, such as when taking sharp turns at high speeds or when driving on damp surfaces.


Your plates on your car must be lit by small lamps located just above them at all times and an improperly working lamp is enough to cause a serious problem during MOT testing. This is one of the fastest, simplest, and most cost-effective repairs that you can make for your car, especially when you consider the frustration of a failed test. Therefore, it is always in your best interests to walk around your vehicle and take a close look at all your lamps, reflectors, and electrical equipment to ensure that all is working as it should be before you attempt to bring it in for testing.

The professionals who perform this test on your vehicle want to see you succeed and will ensure that they carefully and without bias inspect your vehicle for any faults. Should your vehicle fail initial examinations, you will receive a full report as to why it failed and how you may repair and correct the problem.
