How we worked this out
These figures come from DVSA's anonymised MOT testing data for 2023, covering every class 4 MOT test in Great Britain (cars, taxis and light vans). We count normal tests only, not retests. A test counts as a first-time pass if the vehicle passed without any repairs. Tests where defects were fixed at the test centre within an hour (PRS) count as fails, in line with DVSA's own statistics. Failure areas show the share of tests with at least one failure in that area, so the figures add up to more than the fail rate.
