What the MOT record shows

No single area dominates — visibility (5.4%) and lighting & signalling (5.1%) are close, so failures are spread across several systems rather than one weak point.

Condition tracks the odometer closely. Failures run at 8.8% in the 0-30k band and 16.5% in the 150k+ band, a 7.6-point spread.
