The whole point of an MOT inspection is to ensure vehicles on UK roads are safe and environmentally friendly.
Why do vehicles fail their MOT inspections?
Most of the time, a vehicle fails its MOT inspection due to avoidable issues such as worn, underinflated tyres, blown light bulbs, or unresponsive or spongy brakes.
For the best results, before booking your slot for a car MOT in Loughborough, for instance, resolve the lingering issues of the vehicle. That will ensure your time and money don’t go to waste.
The Most Frequent MOT Failure Points
MOT inspections happen annually. There is plenty of time between inspections to resolve lingering issues that often cause a vehicle to fail its MOT inspection. In that note, here is a list of common reasons a vehicle is labelled as unfit for UK roads.
Blown Bulbs and Faulty Lights
Most MOT inspectors readily disqualify vehicles that come in for the inspection with faulty lights, broken light housings, or blown bulbs.
To prevent this, before bringing in the vehicle, turn on all the lights and then walk around it. If any light-related issues stick out to you like a sore thumb, get that fixed at a reputable shop like CMV Service & Repair.
Worn Tyres and Low Pressure
A vehicle’s tyres are the only point of contact between it and the road. If a vehicle’s tyres are worn and underinflated, you can lose traction and increase stopping distance. No wonder vehicles with these issues tend to fail their MOT inspections.
To keep that from happening, if the tread depth on your vehicle’s tyres hits or falls below 1.6mm, replace them with fresh tyres. Additionally, never drive your vehicle with under- or overinflated tyres.
That is downright dangerous.
Spongy or Unresponsive Brakes
Do the brakes of your vehicle squeal whenever you step hard on the brake pedal? That indicates the brake pads are worn out and need to be replaced.
Alternatively, if the noise resembles a metal-on-metal grind, it means the brake rotors (discs) are worn out.
In each case, the only solution is to replace the worn parts with OEM replacements. A vehicle’s brakes are its primary defence against fatal accidents.
If the brakes on a vehicle are spongy or, in the worst cases, unresponsive, then surely it will fail its MOT inspection, don’t you think?
Smooth Sailing For Your Next Inspection
One of the most frustrating aspects of vehicle ownership is when it fails its MOT. To prevent that, develop the habit of running periodic self-checks of the vehicle.
