Understanding the MOT Inspection Checklist (VT40)
The MOT (Ministry of Transport) test is an annual requirement for most vehicles over three years old in the UK. Its primary purpose is to ensure that vehicles are safe to drive and meet environmental standards. The inspection itself is carried out by an authorised MOT test centre, and the results are recorded on a specific form known as the VT40, the MOT inspection checklist. This document is crucial as it details every aspect of the vehicle that is examined and highlights any potential issues or outright failures. For vehicle owners, understanding what the VT40 covers is key to preparing for the test and ensuring their vehicle remains roadworthy.
What is the MOT Inspection Checklist (VT40)?
The VT40 is the official document used by MOT testers to record the results of the inspection. It's essentially a comprehensive list of all the components and systems that are checked on a vehicle. Each item on the checklist has a corresponding pass or fail status. If a vehicle passes, it receives an MOT certificate, which is legally required to drive on public roads. If it fails, the VT40 will clearly state the reasons for failure, along with any advisory notices for issues that are not critical enough to cause an immediate failure but may require attention in the near future.
Key Areas Covered in the MOT Inspection
The MOT test is thorough, covering a wide range of safety-critical areas. While the exact number of items checked can vary slightly depending on the type of vehicle, the core components remain consistent. Here's a breakdown of the main categories:
1. Lights and Signalling
This section checks the functionality and condition of all lights on the vehicle, including headlights (dipped and main beam), taillights, brake lights, indicators, hazard lights, and number plate lights. Proper functioning is essential for visibility and communication with other road users. Testers will also check for correct alignment of headlights, especially the beam pattern, to prevent dazzling oncoming drivers.
2. Steering and Suspension
The steering and suspension systems are vital for a vehicle's control and stability. The MOT inspection will examine steering systems for excessive play or stiffness, ensuring the steering wheel returns correctly. Suspension components such as shock absorbers, springs, and linkages are checked for wear, damage, or leaks. Uneven tyre wear can also be an indicator of suspension issues.
3. Brakes
Arguably the most critical safety system, the brakes are meticulously inspected. This includes checking the condition and effectiveness of the braking system, including the brake pedal, brake fluid, brake lines, hoses, and the condition of brake discs and pads. Testers will perform brake tests to ensure they meet legal stopping distances and that the braking force is balanced between the wheels.
4. Tyres and Wheels
Tyre condition is paramount for road safety. The MOT checks for adequate tread depth (a minimum of 1.6mm across the central three-quarters of the breadth of the tread), any cuts, bulges, or damage to the tyre walls, and whether the tyres are correctly inflated. Wheels are also inspected for damage, distortion, and secure mounting. Mismatched tyres on the same axle are also a common failure point.
5. Body, Chassis, and Structure
The structural integrity of the vehicle is a major concern. The MOT tester will examine the bodywork for significant corrosion or damage that could affect the vehicle's strength, particularly around the chassis, suspension mounting points, and wheel arches. Any sharp edges or protruding parts that could pose a danger to pedestrians are also checked.
6. Exhaust Emissions and Noise
To ensure compliance with environmental regulations, the MOT test includes checks on exhaust emissions. The vehicle's exhaust system is inspected for leaks, corrosion, and secure mounting. A 'gas analyser' is used to measure the levels of harmful pollutants in the exhaust gases. Excessive noise from the exhaust is also a reason for failure.
7. Windscreen, Wipers, and Washers
Visibility is crucial for safe driving. The MOT inspects the windscreen for damage that could obstruct the driver's view (e.g., cracks or chips in the driver's direct line of sight). The condition and effectiveness of the windscreen wipers and washers are also checked to ensure they clear the screen effectively.
8. Seats and Seatbelts
All seats and seatbelts fitted to the vehicle are inspected. This includes checking for wear and tear, proper functioning of the locking mechanism, and any damage. The anchorages of the seatbelts are also examined to ensure they are secure.
9. Fuel System
The fuel system is checked for leaks, corrosion, and secure connections. The fuel cap must also seal correctly.
10. Doors, Mirrors, and Other External Fittings
This covers a range of items, including the operation of doors (opening and closing from both the inside and outside), the condition and security of mirrors, and the presence and condition of the bonnet and boot latches. Number plates must also be present, correctly fitted, and legible.
Common Reasons for MOT Failure
Understanding common failure points can help you prepare your vehicle and avoid an unnecessary second test. Here are some of the most frequent reasons vehicles fail their MOT:
- Tyres: Insufficient tread depth, damage, or incorrect pressures.
- Brakes: Worn brake pads or discs, faulty brake fluid, or inefficient braking performance.
- Lights: Non-functioning bulbs, incorrect colour of lights, or misaligned headlights.
- Visibility: Cracked or damaged windscreen, faulty wipers or washers.
- Suspension: Worn shock absorbers, damaged springs, or excessive play in suspension components.
- Exhaust Emissions: High levels of pollutants or a noisy exhaust.
- Bodywork: Significant corrosion or sharp edges that compromise structural integrity or safety.
- Seatbelts: Damaged or malfunctioning seatbelts or their anchorages.
How to Prepare for Your MOT Test
A little preparation can go a long way in ensuring your vehicle passes its MOT first time:
- Check your tyres: Ensure they have adequate tread depth and are free from damage.
- Inspect your lights: Test all your lights, including brake and indicator lights.
- Check your windscreen: Look for any chips or cracks that might cause a failure.
- Test your wipers and washers: Make sure they clear the screen effectively.
- Check your brake fluid: Ensure the level is correct and the fluid is clean.
- Listen for unusual noises: Any strange sounds from the exhaust or suspension could be an issue.
- Ensure all mirrors are secure: Check they are not cracked or loose.
The MOT Certificate and Advisories
After the inspection, you will receive either an MOT pass certificate or a refusal of an MOT test certificate. If your vehicle passes, you'll get a certificate stating the test date and expiry date. If it fails, the VT40 will detail the reasons for failure. It will also list any 'advisories'. These are issues that did not cause an immediate failure but are noted as potentially becoming a problem in the future. It's wise to address advisories promptly to prevent them from escalating into failures at your next MOT.
What Happens After a Failed MOT?
If your vehicle fails the MOT, you cannot legally drive it on the road unless you are driving it to a pre-booked appointment for repair or to a pre-booked MOT test. You will need to get the necessary repairs done and then have the vehicle re-tested. Some test centres offer a partial re-test, where only specific items are checked, which can be more cost-effective.
Comparing MOT Costs
The maximum fee for an MOT test is set by the government, but test centres can charge less. It’s worth shopping around for the best price, but always ensure you choose a reputable and authorised test centre. Some garages may offer MOT tests as part of a service package.
| Vehicle Type | Maximum Fee (£) |
|---|---|
| Cars (Class 1) | £54.85 |
| Motorcycles (Class 2) | £29.65 |
| Tricycles (over 450kg) | £29.65 |
Note: These are maximum fees. Actual prices may vary between test centres.
