A leading motoring expert has issued a stark warning to UK drivers, revealing the three most frequent reasons vehicles fail their annual MOT test. Simple, avoidable issues are costing motorists time and money.
Lighting and Electrical Faults Top the List
Andrew Jervis, CEO of automotive service platform ClickMechanic, has highlighted that problems with lights and electrics remain the single biggest cause of an initial MOT failure. Citing Driver and Vehicle Standards Agency (DVSA) data, he notes these faults account for roughly 11% of all test failures.
"The most common MOT failures remain surprisingly basic," Jervis told the Express. He explained that a blown bulb or a misaligned headlamp is often to blame. A growing reliance on dashboard warning systems is part of the problem, as not all vehicles alert the driver when a light fails.
This finding is supported by the RAC, which has previously stated that nearly one-fifth of all cars fail their MOT due to a lighting issue. They advise drivers to manually switch on all lights and walk around their vehicle to check headlights, indicators, sidelights, fog lights, and number plate lights are functioning correctly.
Suspension Failures on the Rise
The second most prevalent category of MOT failure is suspension damage, which now accounts for close to 9% of faults. Jervis points to a combination of factors for this steady increase.
"While heavier vehicles and the rise of SUVs play a role, worsening road conditions and pothole damage are a major contributing factor," he said. He linked the issue directly to strained local authority repair budgets, stating, "drivers are paying the price through repeated suspension damage."
How to Avoid a Costly MOT Failure
The majority of vehicles in England, Scotland, and Wales that are over three years old require an annual MOT test, while in Northern Ireland the first test is due after four years. Failing this mandatory check can lead to expensive repairs and immediate retest fees.
To improve your chances of passing first time, experts recommend a few simple pre-test checks:
- Conduct a full light check: As advised by the RAC, manually test every exterior light on your car.
- Listen for suspension noises: Knocking or clunking sounds over bumps can indicate worn components.
- Check tyre condition and pressure: Ensure tread depth is above the legal minimum of 1.6mm and look for sidewall damage.
- Top up fluids: Ensure screenwash, engine oil, and brake fluid are at the correct levels.
Addressing these common, often minor issues before presenting your car for its MOT can save drivers significant hassle and unexpected repair bills, ensuring their vehicle remains safe, legal, and roadworthy.
