What checks are involved during an MOT test in Aylesbury and what can you do to avoid failing?

posted by 

If you need an MOT test in Aylesbury, we have a great experience and know-how of the easy checks that can help you avoid a first-time failure. There are many items checked during an MOT and we, unfortunately, see many faults that fail the test that could be avoided with routine maintenance.

We’ve compiled this list of just some of the checks that must be carried out during an MOT and simple ways you can avoid failing the test with just a little maintenance.


The tread depth of your tyres must be above the legal limit of 1.6mm in a continuous band around each tyre. Tyres will also be examined for any cuts, tears, bulges and any other type of damage or deformity.

Occasionally check the tread depth of your tyres and look for any damage and replace them as necessary to avoid failing an MOT when the time comes.


The condition of your brakes and pedals are checked as well as a brake performance test. Additionally, any warning lights related to your brakes will also be inspected to ensure they are working correctly.

You can read more about looking after and inspecting the state of your brakes in our post here.

Electrics and Lamps

All indicators and reflectors on the vehicle must be securely positioned, easily visible and not affected by any other light on the vehicle and function with a single switch operation. Headlight dim levels will be tested to ensure they do not temporarily blind other drivers and light colours are also checked to ensure they are mainly white and any pairs of lights are both the same colour.

The horn on the vehicle will be tested to ensure it is loud and continuous, all electrical sockets are checked that they correctly operate and the battery is inspected to confirm it is secure and not showing any signs of leakage.

If you notice any lights not working correctly or emitting the wrong colour make sure to get them fixed or replaced as soon as possible.

Steering and Suspension

Steering oil levels will be checked and all aspects of the steering will be tested to ensure everything works correctly. The steering lock mechanism must work correctly and all dashboard warning lights related to steering will be checked.

You can read more about dashboard warning lights in our post here.
