Top failures
Dipped beam headlamp not working 1.4%
A failed dipped beam makes it hard to see and be seen at night, so the lamp needs fixing before driving.
Tyre cut reaching ply or cords 1.18%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Brake pads worn below 1.5mm 1.02%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Tyre tread below 1.6mm 0.95%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Main beam headlamp not working 0.77%
A failed main beam reduces night-time visibility on unlit roads, so the headlamp should be repaired promptly.
Tyre ply or cords exposed 0.67%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Common advisories
Tyre worn close to legal limit (9.64%) · Brake disc pitted or scored (8.88%) · Tyre slightly damaged or cracking (3.65%) · Brake pads wearing thin (3.62%) · Child seat limits belt inspection (2.63%) · Nail in tyre, monitor (1.94%)
