Identifying Potential Issues: Causes For Mot Test Failure

By Matthew Short 12 Jun, 2023 210

MOT tests are critical for ensuring that a vehicle is up to the requirements for road worthiness. It is an annual test that checks a vehicle’s components, such as brakes, suspension, lights, and exhaust system, to make sure that they will not pose any danger to the driver, passengers, or other motorists. Though there is a standard procedure for MOT Luton testing, it is important for vehicle owners and mechanics alike to stay alert to potential problems that could cause an MOT test failure.

The first and most common cause of MOT test failure is a faulty brake system. When the brakes become worn or damaged over time, they can be unable to provide the necessary amount of stopping power. This can be due to worn down brake pads, worn brake rotors, or a defective brake line. In order to pass the MOT test, these components need to be inspected and serviced before the test date. This is important for ensuring the vehicle stays on the road and handling appropriately. A suspension system can become defective over time due to worn or cracked shock absorbers, loose components, or a worn-out steering system. So, it is important to check and replace these components before the test to reduce the chances of failure. Exhausts and emissions can also be a source of MOT test failure. The exhaust system needs to be inspected to check for blockages or leaks, which can lead to the release of dangerous pollutants and hazardous fumes. Similarly, the emission system needs to be examined to check that the vehicle is emitting the correct amounts of gases and that the catalytic converter is in working order.

Headlights and reflectors are also integral to ensure the safety of a vehicle and its passengers. Poorly aimed headlights can lead to visibility problems, while defective reflectors can make it hard to spot the vehicle. To prevent MOT test failure due to these issues, they should be inspected and adjusted periodically.

The seat belts also need to be examined and maintained to make sure they can act as a safety measure in the case of emergency. If the seat belts are worn or damaged, they might not be able to withstand the force of an impact or protect the occupants in a crash.

These are just some of the potential issues that can lead to MOT test failure. To ensure the vehicle is up to the required standards, it is important to regularly inspect and maintain the different components to make sure they are in good working condition. A qualified technician can provide invaluable advice and help to make sure your vehicle is safe and compliant.

Understanding the MOT Test: A Breakdown

The MOT Test is an annual test that assesses the safety and road worthiness of vehicles more than three years old. The aim of the test is to ensure that vehicles meet the legal standards set out by the Department for Transport.

The test is divided into different sections, each of which contains documents that have to be correctly completed in order for the test to pass. The sections include:

  • Vehicle Identification – this section includes details such as the registration number, make, and model of the vehicle being tested.
  • Lights – this section checks the overall condition, operation, and alignment of the headlights, indicators, and hazard warning lights.
  • Steering & Suspension – this part of the test looks at the steering wheel, tyres, wheel alignment, and suspension components to ensure that they are all working correctly.
  • Brakes – this part of the test looks at the effectiveness of the brakes by checking the brake discs and pads.
  • Tyres – this section checks the overall condition of the tyres to ensure they are legal for use on the road. It also measures the tread depth of the tyres.
  • General Vehicle Condition – this part of the test looks at the overall condition of the vehicle, checking for any rust, corrosion or broken components.
  • Emissions – this part of the test analyzes the amount of pollution that the vehicle emits. This is done through a smoke test and a gas test.
  • Mirrors & Washers – this part of the test checks to ensure that the rear-view mirrors are adjusted correctly and that the windscreen washers and wipers are working properly.
  • Seatbelts – this section looks at the overall condition of the seat belts and how they are secured in the vehicle.

Once the tests have been completed, the vehicle must score a minimum of 6 points out of 10 for the certificate to be issued. If it fails, the owner will have to take the car back to the garage to be fixed and re-tested.

The MOT Luton test is a hugely important part of keeping a vehicle safe and roadworthy, and if you are the owner of a car more than three years old, it is essential that you understand the test and ensure that your vehicle passes it. By doing so, you can reduce the risk of accidents and improve your safety on the roads.
