How to Prepare Your Car for Its MOT
An MOT test is a necessary annual requirement for vehicles over three years old in the UK, ensuring that they meet road safety and environmental standards. Failing an MOT can be frustrating, particularly when the issues are minor and could have been easily avoided. Preparing a car for its MOT in advance can increase the likelihood of passing the test and reduce the need for costly repairs.
Checking Lights and Indicators
One of the most common reasons for an MOT failure is faulty lights. The headlights, indicators, brake lights, reversing lights, and number plate lights all need to be fully functional. Testing these before the MOT can highlight any issues that require attention. If a bulb is not working, replacing it is a simple and cost-effective fix. Headlight alignment is also checked during the test, so ensuring that they are positioned correctly can help prevent failure.
Inspecting Tyres for Wear and Tear
Tyres play a crucial role in road safety, and their condition is carefully examined during an MOT. They must have a minimum tread depth of 1.6mm across the central three-quarters of the tyre and be free from any visible damage, such as cuts or bulges. Checking tyre pressure and ensuring they are evenly worn can also be beneficial. If there is uneven wear, it may indicate a problem with wheel alignment or suspension, which should be addressed before the test.
Testing the Brakes
The braking system is a critical component of any vehicle, and its efficiency is tested thoroughly during an MOT. Conducting a basic brake test by applying the brakes while driving at a low speed can help identify any issues. If there are any unusual noises, vibrations, or if the car pulls to one side when braking, it may indicate worn brake pads or discs that need replacing. Ensuring that the handbrake engages properly and does not require excessive force can also prevent potential failures.
Ensuring Visibility Through the Windscreen
A clear and undamaged windscreen is essential for passing an MOT. Chips or cracks larger than 10mm in the driver’s direct line of sight, or 40mm anywhere else, will result in a failure. If the windscreen has minor damage, repairing it before the test is advisable. Wipers must also be in good working condition, with no excessive wear or splits that could compromise visibility. Checking that the washer fluid is topped up ensures that the windscreen can be cleaned effectively during the test.
Assessing the Exhaust and Emissions
The exhaust system must be secure and free from leaks. Excessive noise, smoke, or a loose exhaust can lead to an MOT failure. The emissions test measures the level of pollutants released by the vehicle, and high emissions can indicate a problem with the catalytic converter or fuel system. Running the engine for a period before the test can help reduce emissions, especially for diesel vehicles, as it allows the engine to reach its optimal operating temperature.
Checking Fluid Levels
Ensuring that all essential fluids are at the correct levels can prevent unnecessary issues during an MOT. Engine oil, coolant, brake fluid, and screen wash should all be topped up. Low levels of brake fluid can indicate a leak or worn brake components, which could lead to a failure. Regularly checking and maintaining fluid levels throughout the year can help avoid problems when the MOT is due.
Inspecting the Suspension and Steering
Suspension and steering components must be in good working order to pass an MOT. Any knocking noises or excessive bouncing when pushing down on the car can indicate worn shock absorbers. If the steering feels heavy or unresponsive, it may suggest an issue with the power steering system. Identifying and addressing these problems in advance can help ensure that the vehicle passes the test.
Examining the Bodywork and Number Plates
Structural integrity is an important aspect of an MOT test. Any significant rust or damage that could affect the safety of the vehicle will be noted. Checking that the doors, bonnet, and boot open and close securely is essential. Number plates must be clean, legible, and correctly spaced according to legal requirements. If they are faded, damaged, or incorrectly formatted, they may need to be replaced before the test.
Ensuring Seatbelts Are Functioning Properly
Seatbelts must be in good condition and operate correctly. Checking for fraying, cuts, or damage can help prevent failure. Each seatbelt should latch securely and retract smoothly when released. If there are any warning lights related to airbags or seatbelt pretensioners, they should be investigated and resolved before the MOT.
Carrying Out a General Clean and Inspection
Keeping the vehicle clean, both inside and out, can create a positive impression and make the inspection process smoother. A cluttered interior with excessive dirt can sometimes hinder the tester’s ability to check certain components. Ensuring that the boot is free from obstructions and that spare wheel storage areas are accessible can be helpful.
Taking the time to check and maintain a vehicle before an MOT test can increase the likelihood of passing on the first attempt. Many issues that cause failures are minor and can be easily fixed before the test, reducing the inconvenience of a retest. Regular maintenance throughout the year, rather than just before an MOT, helps ensure a car remains safe and roadworthy.
