MOT Failure Patterns by Age

Cars aged 3-5 years have 90%+ pass rates. Cars aged 5-10 years show increased failures around 15-25%. Cars 10+ years old have failure rates 30-40%. Regular maintenance significantly improves pass rates.

Common Failure Points

Top MOT failures: emissions (20%), brakes (18%), suspension (15%), tyres (12%), lighting (10%). Modern cars are more reliable; older cars show more varied issues. Preventative maintenance prevents most failures.

Preparing for MOT

Check tyre tread, brake pads, bulbs, and fluid levels before your MOT. If warning lights are on, get them diagnosed before testing. Professional pre-MOT checks cost GBP 50-GBP 100 and can identify issues early.
