Top failures
Tyre tread below 1.6mm 3.13%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Number plate does not meet standards 0.57%
The plate does not meet legal specifications, so it must be replaced with a compliant one before the car is driven.
Headlamp aim set too high 0.57%
Headlamps aimed too high can dazzle other drivers, and adjusting them is usually a quick job.
Wiper blade not clearing windscreen 0.45%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Tyre cut reaching ply or cords 0.32%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Windscreen washer fluid insufficient 0.32%
Washers are not supplying enough liquid, so the windscreen cannot be cleared properly, which is a safety issue.
Common advisories
Tyre worn close to legal limit (10.66%) · Tyre worn close to legal limit (1.79%) · Nail in tyre, monitor (1.34%) · Tyre slightly damaged or cracking (0.96%) · Brake pads wearing thin (0.89%) · Tyre has a shallow cut (0.64%)
