MOT Test Explained

Every car over three years old (four years in Northern Ireland) in the United Kingdom requires an annual Ministry of Transport (MOT) test. This crucial safety check ensures your vehicle meets the minimum roadworthiness and environmental standards. 

But what exactly does an MOT test involve, and how can you ensure your car passes? This comprehensive guide will answer all your questions about MOT tests.

A Brief History of MOT Tests

The MOT test was first introduced in 1960 following a rise in road accidents. The initial focus was primarily on brakes and steering, but the scope of the test has expanded over time to include various safety and environmental aspects. Today, the MOT plays a vital role in keeping our roads safe and reducing harmful emissions.

What Do They Check on an MOT Test?

A qualified tester will perform a thorough inspection of your vehicle, focusing on key areas like:

• Lights: Headlights, taillights, brake lights, indicators, and fog lights are checked for proper functionality and alignment.

• Brakes: The tester will assess the braking efficiency, pedal feel, and overall condition of the braking system.

• Steering: Precise steering control is crucial, and the MOT will check for any play or looseness in the steering components.

• Suspension: Worn suspension can affect handling and tyre wear. The MOT ensures the suspension provides adequate support and control.

• Tyres: Tread depth, overall condition, and inflation pressure are all checked to ensure your tyres are safe and legal.

• Exhaust Emissions: Modern MOT tests involve an exhaust emissions check to ensure your car meets current environmental regulations.

• Bodywork: The tester will look for any excessive corrosion, sharp edges, or damage that could pose a safety risk.

• Seatbelts: All seatbelts are checked for functionality and proper operation.

For the full list of everything checked during an MOT test, you can refer to the official DVSA guide.

What Are the Different Levels of MOT?

There's only one level of MOT test for cars, ensuring a consistent standard of roadworthiness. However, the results can be categorised as a pass, fail with minor defects (advisories), or fail with major defects.

How Much Does a MOT Cost?

The average cost of an MOT test can vary depending on your location and the garage you choose. However, it typically falls within the range of £40 to £60.

What Will Cause My Car to Fail an MOT?

There are numerous reasons why a car might fail an MOT test. Some common causes include:

• Faulty Lights: Non-functional or incorrectly aimed lights can be a failure.

• Ineffective Brakes: Poor braking performance or a spongy brake pedal will lead to failure.

• Worn Tyres: Tyres with insufficient tread depth or damage are a safety hazard and will cause failure.

• Excessive Exhaust Emissions: Vehicles exceeding emission limits will not pass the MOT.

• Major Fluid Leaks: Significant leaks of oil, coolant, or brake fluid can be a failure.

Can I Drive My Car for 10 Days After MOT Failure?

No, you cannot legally drive your car on a public road if it has failed an MOT test. However, you can drive it to a repair centre to rectify the issues and get a retest.

Are Minor Defects a Fail?

Minor defects, also known as advisories, are highlighted during the MOT but do not result in an immediate failure. However, it's important to address these issues to prevent them from becoming major problems in the future.

Can I Drive My Car on the Day the MOT Expires?

Technically, yes, you can drive your car on the day your MOT expires. However, it's strongly recommended to have a valid MOT certificate at all times to avoid fines and potential insurance issues. You can check the status of your MOT online using the government website.

Can You Drive Your Car After It Fails an MOT?

As mentioned earlier, driving a car with a failed MOT on public roads is illegal. You can only drive it to a designated repair centre for rectification and a retest.

Tips to Pass an MOT Test

Here are some valuable tips to help your car pass the MOT test:

• Regular Servicing: Regular servicing by a qualified mechanic helps identify and address potential issues before they escalate into MOT failures.

• Pre-MOT Inspection: Many garages offer pre-MOT inspections that can identify potential problems and allow you to address them before the actual test.

• Check Lights and Tyres: Regularly ensure all your lights are functioning correctly and replace any faulty bulbs. Inspect your tyres for proper tread depth and inflation pressure.

• Listen for Warning Signs: Unusual noises, vibrations, or warning lights on your dashboard could indicate potential issues that might lead to an MOT failure.

• Address Advisories from Previous MOTs: Don't ignore advisories from your previous MOT test. Get any highlighted issues addressed to prevent them from causing a failure in the next test.

What to Do If Your Car Fails an MOT Test

If your car fails an MOT test, don't panic. The garage will provide you with a failure certificate outlining the specific reasons for failure. You can then choose to have the repairs done at the same garage or take your car to another qualified mechanic to rectify the issues. Once the repairs are complete, you can arrange a retest, which typically incurs a smaller fee than the initial test.
