The annual MOT test can be a source of anxiety for many car owners. The thought of potential failures and costly repairs can be daunting. However, with a little preparation and knowledge, you can significantly improve your car's likelihood of sailing through its MOT on the first attempt. This guide will walk you through key areas to check and simple maintenance steps that can make all the difference.
Understanding the MOT Test
The Ministry of Transport (MOT) test is a compulsory annual inspection for vehicles that are three years old or more. It's designed to ensure your vehicle meets road safety and environmental standards. The test covers various aspects of your car, including:
- Lights: All lights must be the correct colour, bright enough, and free from cracks.
- Tyres: Tyres must have a minimum tread depth of 1.6mm and be free from cuts or bulges.
- Brakes: The braking system is crucial for safety and will be thoroughly checked.
- Steering and Suspension: Components must be in good condition, with no excessive wear or play.
- Exhaust Emissions: Your car's emissions will be tested to ensure they meet legal limits.
- Visibility: The windscreen must be clear, and wipers and washers must function correctly.
- Body and Structure: The car's bodywork will be checked for excessive corrosion or damage that could compromise safety.
- Seats and Seatbelts: All seatbelts must be present, secure, and in good working order.
Pre-MOT Checks: What You Can Do Yourself
While a professional mechanic will conduct the official MOT, there are several checks you can perform yourself to identify and fix minor issues before the test. This proactive approach can save you money and the hassle of a failed MOT.
1. Lights, Lights, Lights!
This is one of the simplest and most common reasons for an MOT failure. Walk around your car and check that all lights are working correctly:
- Headlights (dipped and main beam)
- Tail lights
- Brake lights (you might need a helper for this)
- Indicator lights (front, rear, and side)
- Fog lights (front and rear, if fitted)
- Number plate light
Ensure bulbs are the correct type and colour. If a bulb is out, replacing it is a straightforward task for most car owners.
2. Tyre Condition and Tread Depth
Tyres are vital for safety and grip. Check:
- Tread Depth: The legal minimum is 1.6mm across the central three-quarters of the tyre's width. You can check this using a tyre tread depth gauge or by looking at the wear indicators built into the tyre.
- Damage: Inspect for cuts, bulges, or exposed cords on the sidewalls and tread.
- Pressure: Ensure tyres are inflated to the manufacturer's recommended pressure (usually found on a sticker in the doorjamb or in the owner's manual).
Uneven tyre wear can also indicate an issue with your car's alignment or suspension, which are also tested in the MOT.
3. Windscreen and Wipers
A clear view of the road is paramount. Check:
- Windscreen: Ensure there are no chips or cracks larger than 10mm in the driver's direct line of sight, or larger than 40mm elsewhere on the windscreen.
- Wipers: Test the wipers to make sure they clear the windscreen effectively and that the washer fluid sprays correctly. Replace worn wiper blades if they leave streaks or judder.
4. Brakes
While you can't fully test your brakes without specialist equipment, you can listen for any unusual noises (like grinding or squealing) when braking and feel for any sponginess or pulsations in the brake pedal. If you notice any of these, it's worth getting them checked professionally.
5. Fluid Levels
Low fluid levels can cause various issues. Check:
- Engine Oil: Ensure the oil level is between the minimum and maximum marks on the dipstick.
- Brake Fluid: Check the level in its reservoir.
- Coolant: Ensure the coolant level is adequate.
- Screenwash: Top up if necessary.
Common MOT Failure Points and How to Avoid Them
Certain issues are more frequently cited as reasons for MOT failure. Being aware of these can help you focus your pre-test checks.
Tyre Wear and Damage
As mentioned, worn tyres or tyres with damage are a guaranteed fail. Regularly checking your tyres and replacing them when they reach the legal limit or show signs of damage is crucial.
Lighting Faults
Faulty bulbs or incorrect lighting are extremely common. Ensure all lights are working and are the correct type.
Brake System Issues
Worn brake pads, discs, or issues with the brake fluid are serious safety concerns. Any weakness or abnormality in the braking system will result in a failure.
Suspension Wear
Worn shock absorbers, springs, or bushes can affect handling and safety. Look out for excessive bouncing or unusual noises when going over bumps.
Exhaust Emissions
Modern cars are fitted with catalytic converters to reduce emissions. If yours is faulty or has been tampered with, it can lead to a fail. Regular servicing can help keep your emissions within the legal limits.
Corrosion
While minor surface rust might be acceptable, significant corrosion on structural parts of the car, such as the chassis, suspension mounting points, or around the wheel arches, can cause an MOT failure. Check for rust holes or areas where the metal has significantly weakened.
When to Book Your MOT
You can book your MOT up to one month before your current MOT expires. The new expiry date will be extended by 12 months from the original expiry date, not from the date of the test. For example, if your MOT expires on 1st October, you can take the test anytime from 1st September. If you pass, your new expiry date will still be 1st October the following year.
What Happens if Your Car Fails?
If your car fails its MOT, you will be given a report detailing the reasons for failure. You can typically leave the test centre and drive your car if the existing MOT is still valid and the failure items are not classified as 'dangerous'. However, it is illegal to drive a vehicle that has failed its MOT if any of the defects are deemed dangerous. You will need to have the necessary repairs carried out and then present the vehicle for a partial re-test. Depending on the nature of the failure and where the re-test is conducted, some items may be re-tested for free.
Consider a Pre-MOT Check
Many garages offer a pre-MOT check service. This is a comprehensive inspection that identifies potential issues before the official test. While this service usually comes at a cost, it can be a worthwhile investment if you're unsure about your car's condition, as it can help you avoid the cost and inconvenience of a failed MOT.
Table: Common MOT Failures and Simple Checks
| Failure Item | What to Check | Likelihood of DIY Fix |
|---|---|---|
| Lights not working | All external lights, including brake lights and indicators. | High (bulb replacement) |
| Tyre tread below 1.6mm | Check tread depth across all tyres. | High (tyre replacement) |
| Damaged tyres | Inspect sidewalls and tread for cuts, bulges. | High (tyre replacement) |
| Windscreen chips/cracks | Check for damage in driver's direct line of sight. | Medium (minor chips can sometimes be repaired) |
| Wiper/washer malfunction | Test wipers clear the screen, check washer fluid. | High (replace blades, top up fluid) |
| Excessive corrosion | Inspect chassis, wheel arches, structural areas. | Low to Medium (depends on severity) |
| Brake warning light on | Check dashboard warning lights. | Low (indicates a serious issue) |
