Pre-MOT Checks: Avoid Fines

Preparing Your Vehicle for its MOT Test

The annual MOT (Ministry of Transport) test is a legal requirement for most vehicles in the UK over three years old. It ensures your car meets roadworthiness and environmental standards. While the MOT centre will conduct a thorough inspection, performing some basic checks yourself beforehand can significantly increase your chances of a pass and save you potential re-test fees and stress. This guide will walk you through the essential checks you should carry out before booking your MOT appointment.

Lights: Your Beacon of Safety

Your car's lighting system is crucial for visibility and signalling your intentions to other road users. A faulty light is a common reason for MOT failure. Ensure all your lights are functioning correctly, including:

• Headlights: Check both dipped and main beam settings. Make sure they are the correct colour (white for front, amber for rear indicators, red for rear lights and stop lights).
• Tail lights: These should be red and illuminated when the headlights are on.
• Stop lights: These are brighter than tail lights and should illuminate when the brake pedal is pressed. Get someone to help you check these.
• Indicators: All indicators (front, rear, and side repeaters) must flash amber at a consistent rate.
• Hazard lights: Ensure all indicators flash simultaneously when the hazard warning lights are activated.
• Number plate lights: These must be white and illuminate the rear registration plate.

Tip: Keep a spare set of common bulbs handy, as replacing a blown bulb is a simple fix that can prevent an MOT failure.

Tyres: The Foundation of Your Journey

Tyres are your only contact with the road, so their condition is paramount. The MOT test will check for:

• Tread depth: The legal minimum tread depth in the UK is 1.6mm across the central three-quarters of the tyre's breadth. You can check this using a tread depth gauge or a 20p coin – if the outer band of the coin is visible when inserted into the tread grooves, your tyres may be below the legal limit.
• Tyre condition: Look for any cuts, bulges, or significant damage to the tyre walls.
• Tyre pressure: While not directly tested for the MOT, correctly inflated tyres are vital for safety and wear. Check your car's manual or the sticker on the door frame for the recommended pressures.
• Matching tyres: It's recommended to have matching tyres on the same axle (same brand, model, and tread pattern). While not a strict MOT failure, mismatched tyres can affect handling and safety.

Crucially: Worn tyres or tyres with incorrect tread depth are a definite failure point.

Brakes: Your Stopping Power

Your braking system is critical for safety. While a full brake test is conducted at the MOT centre, you can perform some preliminary checks:

• Brake pedal feel: The pedal should feel firm and not spongy. If it feels soft or goes too close to the floor, there might be an issue with the brake fluid or the system itself.
• Brake warning light: Ensure the brake warning light on your dashboard illuminates when you first start the engine and then goes out. If it stays on, it indicates a problem.
• Handbrake: The handbrake should hold the vehicle firmly. Test it on a slight incline if possible.

Important: Any issues with your brakes can lead to a dangerous driving situation and will result in MOT failure.

Windscreen and Wipers: Clear Vision

Your ability to see the road clearly is essential. The MOT will assess:

• Windscreen: Check for any chips or cracks in your windscreen. A chip larger than 10mm in the driver's direct line of sight, or a crack larger than 40mm anywhere on the windscreen, will cause your vehicle to fail.
• Wipers: Ensure your wipers clear the windscreen effectively without leaving streaks. Check the wiper blades for any signs of wear or damage.
• Washers: Make sure the windscreen washer fluid sprays correctly onto the windscreen.

Remember: Impaired visibility is a significant safety hazard.

Horn: Alerting Others

The horn is a vital safety device for alerting other road users to your presence. Ensure your horn works correctly and produces a consistent sound. A faulty horn will lead to an MOT failure.

Bodywork and Structure: The Car's Integrity

The MOT test will examine the general condition of your car's bodywork for anything that could be dangerous:

• Rust: Excessive corrosion, particularly on structural components like the chassis, suspension mounts, or inner wheel arches, can lead to failure. Check areas prone to rust, such as wheel arches, sills, and door bottoms.
• Sharp edges: Any sharp or protruding parts that could injure pedestrians or other road users will also be a cause for concern.
• Doors: Ensure all doors open and close correctly from both the inside and outside.
• Bonnet and boot: These must be securely fastened and able to be opened.

Focus on: Areas that are critical to the structural integrity of the vehicle.

Exhaust Emissions: Environmental Responsibility

Your car's exhaust system will be tested for emissions. While you can't directly test this at home, ensuring your car is serviced regularly and running efficiently can help. If your car has a diesel particulate filter (DPF), ensure it's not blocked, as this can lead to emissions test failure.

Seatbelts: Safety First

All seatbelts must be present, in good condition, and easily accessible. Check that they retract smoothly and that the buckles fasten securely. Any frayed or damaged seatbelts will result in a fail.

Mirrors: Your Rearward View

Your car must have at least one mirror, but typically you'll have side mirrors on both sides and an interior mirror. Ensure they are securely fitted and not cracked. The mirror on the driver's side is a mandatory requirement.

Dashboard Warning Lights: What They Mean

Certain dashboard warning lights indicate a problem that could lead to MOT failure if they are illuminated when they shouldn't be, or if they don't illuminate at all when the ignition is turned on (e.g., ABS, airbag warning lights). If any of these lights remain on, it's advisable to get them checked by a mechanic before your MOT.

Fluid Levels: Keeping Things Running Smoothly

While not a direct MOT check, ensuring your car has adequate levels of essential fluids contributes to its overall roadworthiness:

• Engine oil: Check the oil level using the dipstick.
• Coolant: Ensure the coolant level is between the minimum and maximum marks.
• Brake fluid: Check the brake fluid level in its reservoir.
• Washer fluid: Top up if necessary for clear visibility.

Other Important Checks: The Finer Details

• Number plate: Ensure your number plate is clean, legible, and securely fitted. It should be illuminated at night.
• Steering and suspension: While you can't fully test these, listen for any unusual noises when turning or driving over bumps.
• Fuel cap: Make sure the fuel cap is present and can be securely fastened.

Common MOT Failure Points Summarised

Frequently Asked Questions

Q1: What if my car fails the MOT?

A1: If your car fails, the MOT centre will provide you with a 'refusal of an MOT test certificate' which details the reasons for failure. You can have the necessary repairs made and then have a partial re-test, usually within 10 working days, to avoid a full re-test fee.

Q2: Can I drive my car if it fails the MOT?

A2: You can continue to drive your car if it fails its MOT as long as the existing MOT certificate is still valid and the failure is not due to a dangerous defect. If the defect is dangerous, you must not drive the vehicle until it has been repaired.

Q3: How much does an MOT cost?

A3: The maximum price for an MOT is set by the government. For cars, it's currently £54.85. However, many garages offer MOTs for a lower price.

Q4: When should I book my MOT?

A4: You can book your MOT up to one month before your current MOT expires. This means you can keep the same annual renewal date for the following year.

Conclusion: Drive with Confidence

By dedicating a little time to perform these pre-MOT checks, you can significantly reduce the likelihood of your vehicle failing its annual inspection. It not only saves you money on potential re-tests but also ensures your vehicle is safe and legal to drive. Remember, a well-maintained car is a safer car for you, your passengers, and everyone else on the road. Don't leave it to chance; be prepared and drive with confidence knowing your vehicle is ready for its MOT.
