Common questions

What is the MOT pass rate in Truro?
68.2% of MOT tests in the Truro postcode area (TR) pass once results are adjusted for the age and mileage of the cars tested, which is below the national average of 72.2%. The unadjusted figure is 65.1%. That ranks Truro 99 of 118 areas in England, Scotland and Wales.
What do cars fail on most in Truro?
The item recorded most often on failed tests in Truro is "Tyre tread depth not in accordance with the requirements", in 15.4% of failed tests, followed by "A lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning" (10.0%). Corrosion-related items are recorded 13.1 times per 100 failed tests here, which ranks 12 of 118 areas for corrosion.
Does this mean garages here are stricter or more lenient?
No. The figure describes the cars tested in Truro, not the testers. Every MOT station applies the same inspection manual, and DVSA monitors testing standards nationally. A regional difference reflects the local fleet and local conditions — roads, weather, salt, how far cars are driven — rather than how hard the test is.
Is Truro a bad area to buy a used car from?
Not necessarily, but check underneath. Corrosion is recorded far more often on failed tests here than the national norm, so a car that has spent its life in Truro deserves a proper look at brake pipes, suspension mountings and sills before purchase. The MOT history will show whether corrosion advisories have been building up.
