Top MOT failures
- 1
Wiper blade not clearing windscreen 0.91% of tests
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
- 2
Tyre cut reaching ply or cords 0.65% of tests
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
- 3
Tyre ply or cords exposed 0.48% of tests
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
- 4
Headlamp aim set too low 0.46% of tests
Headlamps aimed too low light the road poorly and reduce the driver's view ahead, especially at night.
- 5
Tyre tread below 1.6mm 0.43% of tests
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
- 6
Tyre bulge from structural failure 0.35% of tests
A bulge means the tyre's structure has failed and it could burst suddenly, so it must be replaced at once.
- 7
Headlamp aim set too high 0.3% of tests
Headlamps aimed too high can dazzle other drivers, and adjusting them is usually a quick job.
- 8
Tyre pressure monitoring system faulty 0.29% of tests
A faulty tyre pressure monitor cannot warn about low tyre pressure, so check tyres manually and have the fault diagnosed.
Most common advisories
