Any broken or malfunctioning lights can lead to an MOT failure, as they impair your visibility or ability to signal intentions on the road. It's important to check that all lights are of the correct brightness and colour before the MOT test, helping to reduce the risk of failure and ensuring your vehicle is safe to drive.
Windscreen and Wipers
The windscreen and wipers are vital for clear visibility, especially in poor weather conditions. During the MOT test, the windscreen is inspected for any cracks or chips, particularly in the driver’s line of sight. Even small chips can escalate into larger cracks if left unchecked. The wipers are also tested to ensure they effectively clear the windscreen of rain or debris. Any damage to the windscreen or faulty wipers could lead to an MOT failure. Ensuring the windscreen is free from damage and the wipers function properly will help you pass the MOT and stay safe on the road.
Tyres and Wheels
Tyres and wheels are vital for maintaining control and stability on UK roads, especially given the unpredictable weather. The MOT checks that tyres meet the UK’s legal minimum tread depth of 1.6mm across the central part of the tyre. It also ensures that the tyres are free from cuts, bulges, or damage, which could cause a blowout. Wheels are checked for cracks and secure attachment, as any weakness could compromise vehicle safety. Keeping your tyres and wheels in good condition not only helps you pass the MOT but also improves overall driving safety and performance.

A well-maintained engine and fuel system will improve your vehicle's performance and fuel efficiency. Addressing leaks and damage before the MOT can prevent a failure and reduce the risk of costly repairs.
Exhaust and Emissions
The exhaust system is checked for leaks and damage, while emissions are tested to ensure they fall within legal limits. A properly functioning exhaust system channels harmful gases away from the vehicle, reducing pollution and engine noise. Excessive emissions indicate potential engine issues and can cause your vehicle to fail the MOT. Understanding what is checked on an MOT regarding the exhaust system allows you to make necessary repairs, ensuring your vehicle complies with environmental standards.
Battery and Electrics
The MOT test inspects the battery for secure mounting and checks for any signs of corrosion around the terminals. A poorly secured or corroded battery can lead to electrical failures or breakdowns.
