MOT is a recurring snapshot — not a one-off event — and the averages show that clearly.
Across 83.9 million vehicles, the mean number of MOT tests per registration is 6.64.
That is why CARMOTIQ focuses on failure patterns and defect notes over time, not just the latest pass or fail.
A single clean MOT can hide a history of advisories. Age-band research puts one car in context against thousands like it.
