What the MOT record shows

Lighting & signalling dominates the failure mix at 13.8% of all tests — 7.0 points clear of brakes, so it is the first thing to check.

At component level the recurring items are headlamp aim, position lamp and service brake performance — headlamp aim alone was recorded 4,337 times.

A 150k+ example is materially riskier than a 0-30k one: 27.2% versus 11.3%.

Advisories point at the next bill rather than this one: brakes was flagged on 30.0% of tests without failing them.

The trend is worsening — 15.5% of tests failed in 2021 against 22.1% in 2025, the usual pattern as a fleet ages.
