How To Prepare Your Car for Its MOT

Whether you are a do-it-yourself mechanic, or whether you contract your repairs out to someone else, knowing what is needed to pass your MOT is important.

Knowing the major failure issues will help you in knowing how to go about caring for your car in order to pass all the different points.


MOT Failures

The three top areas of failure include:

• Lighting and signaling systems
• Brakes
• Suspension

These three areas account for approximately two-thirds of MOT failures. If you pay attention to these areas when caring for your car, you will more than likely achieve a passing score.

The next three areas of failure do not happen as frequently. They are important items to consider, however. These three include:

• Body
• Fuel
• Tyres

These comprise almost the remaining one-thrid of failures. Other categories are very minor. So, addressing these six areas first will help you in making sure your car will pass the test.

Lighting And Signaling Systems

The key here is to make sure all lights and signals work as they are supposed to. Check them out before you go for your test. If anything doesn’t work or is faulty, get it fixed before seeking certification.

Another thing you must consideris your windscreen. They are part of the overall visibility of the car. If there are any cracks they need to be fixed immediately, unless they are very minor. Most insurance companies allow repair without it affecting your policy.


Since brakes account for such a large percentage of failures, it is important to check that they are in proper working order beforehand. Test their function as well as inspecting the wheels to make sure no fluid is leaking. Anything deficits here will be an automatic failure. In addition to this, it indicates an unsafe driving condition that could cause trouble.

If the brake pads are worn they will cause ineffective braking, or uneven braking, causing the vehicle to veer to one side. This can elicit a failure as well.


Suspension mounts can be checked through the boot. Be sure it is relatively if not completely empty before doing so otherwise you could not only be wasting time but you may very well waste some money as well.


Body condition and cleanliness as a whole is not an integral part of an MOT inspection. However, if it is too dirty underneath to check some of the components, you will have to return after you clean it thoroughly. Any body damage that could lead to unsafe operation of the vehicle will result in a failure. Examine your vehicle for signs of this before taking it in for inspection.


Any fuel leaks will result in an automatic failure. Examine your car closely for visible leaks or smells that might indicate a leak. Fuel is a harmful substance and must be monitored closely to ensure your safety and the safety of others.


Tyres are a big percentage of failures when it comes to an MOT. Not only are specific types required, but they have to be in good condition. Excess wear, or uneven wear, can result in not passing the test. Check before you go in and make sure that you have the required amount of tread left, and that there are no bulging sidewalls or broken wall spaces.

Damage to the rims could also result in a failure. Inspect everything closely and repair or replace any damaged areas. Be sure all the nuts and bolts are present as well if you plan to remove the hubcap.
