MOT Inspection Explained

The MOT (Ministry of Transport) test is an annual inspection of your vehicle that is a legal requirement for most vehicles over three years old in the UK. It's designed to ensure that your car meets the minimum road safety and environmental standards. Think of it as a thorough health check for your vehicle, covering critical areas that could affect its safety and emissions. Passing your MOT is not just about avoiding a fine; it's about ensuring your vehicle is safe for you, your passengers, and other road users.

Why is an MOT Important?

The primary purpose of the MOT test is to enhance road safety and reduce the number of unroadworthy vehicles on our streets. A vehicle that fails its MOT may have defects that could lead to an accident. By having your vehicle regularly inspected, potential problems are identified and rectified before they become serious hazards. Furthermore, driving a vehicle without a valid MOT certificate is illegal and can result in penalties, including fines and penalty points on your driving licence. It also invalidates your car insurance, which is a serious legal and financial risk.

What Does an MOT Inspection Cover?

The MOT test is comprehensive, covering a wide range of components. The specific checks can vary slightly depending on the age and type of your vehicle, but generally include:

1. Lights

All exterior lights, including headlights (both main and dipped beam), taillights, brake lights, indicator lights, and hazard lights, are checked for operation, correct colour, and security. Properly functioning lights are essential for visibility, especially during adverse weather conditions and at night.

2. Steering and Suspension

The steering and suspension systems are vital for vehicle control and stability. Mechanics will inspect for excessive play in the steering wheel, worn ball joints, damaged shock absorbers, and any signs of corrosion or damage to suspension components. A well-maintained steering and suspension system ensures a smooth and safe ride.

3. Brakes

The braking system is arguably the most critical safety component. The MOT test checks the condition and performance of your brakes, including the brake pedal, brake fluid level, brake pipes, hoses, and the effectiveness of the braking system itself. Worn brake pads and discs are common reasons for an MOT failure.

4. Tyres

Tyres are the only point of contact between your vehicle and the road. They are checked for tread depth (the legal minimum is 1.6mm across the central three-quarters of the tread width), damage, cuts, bulges, and correct inflation. Tyres must also be of the correct type and size for your vehicle.

5. Seatbelts

All fitted seatbelts are inspected for wear, damage, and proper functioning. This includes checking the webbing, the locking mechanism, and the anchor points. Seatbelts are a fundamental safety feature, and their condition is taken very seriously.

6. Body and Chassis

The vehicle's bodywork and chassis are inspected for excessive corrosion, sharp edges, or any damage that could pose a risk to the driver, passengers, or other road users. Structural integrity is paramount.

7. Exhaust Emissions

Your vehicle's exhaust system is checked for leaks, and its emissions are tested to ensure they meet the required standards for your vehicle's age and fuel type. This is an important aspect of environmental protection.

8. Windscreen and Wipers

The condition of the windscreen is checked for damage, such as chips or cracks, in the driver's line of sight. Wiper blades are tested for their effectiveness in clearing the windscreen, and the windscreen washer system is checked to ensure it functions correctly.

9. Horn

The horn must be operational and produce a continuous sound. It's a crucial safety device for alerting other road users.

10. Mirrors

All mirrors, including the rearview mirror and door mirrors, are checked for condition, security, and correct positioning. They must provide a clear view of the road behind and to the sides.

11. Doors and Latches

Doors must open and close correctly from both the inside and outside, and all door latches must be secure. This ensures occupants can exit the vehicle in an emergency.

12. Seats

Front seats must be secure and properly fixed. The driver's seat must be able to move forwards and backwards.

13. Registration Plates

The condition, security, and legibility of the vehicle's registration plates are checked. They must be clearly visible and conform to regulations.

Common Reasons for MOT Failure

While the MOT test covers many areas, some common reasons for failure include:

Preparing Your Vehicle for its MOT

A little preparation can go a long way in ensuring your vehicle passes its MOT. Here are some simple checks you can perform yourself:

• Tyre Tread: Check your tyre tread depth using a 20p coin. If you can see the inner band of the coin when inserted into the deepest part of the tread, it's time for new tyres.
• Lights: Walk around your car and check all lights are working correctly. Get a friend to help you check the brake lights and indicators.
• Windscreen: Ensure there are no chips or cracks larger than 10mm in the driver's direct line of sight, or larger than 50mm elsewhere on the windscreen.
• Wipers and Washers: Make sure your wipers clear the screen effectively and the washer fluid sprays correctly.
• Horn: Test your horn to ensure it works.
• Brake Fluid: Check your brake fluid level is between the minimum and maximum marks.
• Fuel Cap: Ensure your fuel cap is secure and seals properly.

What Happens if Your Vehicle Fails the MOT?

If your vehicle fails its MOT, you will be given a refusal of an MOT test certificate. This document will list the reasons for failure. You can continue to drive your vehicle if the existing MOT certificate is still valid, but only if the faults identified do not constitute a danger to yourself or others. It is highly recommended to get the necessary repairs done as soon as possible. You can have the repairs carried out by any garage, and then present your vehicle for a free partial retest within 10 working days if the original test centre undertakes the repairs. If the repairs take longer than 10 working days, or are carried out elsewhere, a full retest will be required.

Booking Your MOT

You can book your MOT up to a month before your current MOT expires. This means you can get your vehicle tested early without losing any days from your existing certificate. For example, if your MOT expires on 15th August, you can get it tested anytime from 15th July onwards, and the new expiry date will be 14th August of the following year.
