What the MOT record shows

No single area dominates — visibility (2.9%) and brakes (2.2%) are close, so failures are spread across several systems rather than one weak point.

At component level the recurring items are headlamp aim, brake pads and wipers — headlamp aim alone was recorded 34 times.

Advisories point at the next bill rather than this one: tyres was flagged on 14.1% of tests without failing them.
