Common questions
- What is the MOT pass rate for Triumph?
- Across 2,186 recorded MOT tests, 83.1% of Triumph tests ended in a pass, against a national average of 72.3%. A make-level figure blends very different cars, so the individual model pages are the more useful comparison.
- What do Triumph cars most often fail their MOT on?
- The most commonly recorded failure item across Triumph tests is "Windscreen washers not working or not providing sufficient fluid to clear the windscreen", appearing in 11.6% of failed tests. One failed test can list several items, so these shares do not add up to 100%.
- Why do some Triumph models not have a pass rate ranking?
- A model is only ranked when its tested examples cover a wide enough spread of ages and mileages for a fair comparison. 0 of the 2 Triumph models here qualify. For the rest we publish the unadjusted rate and the failure patterns, but not a rank, because comparing unadjusted rates mostly sorts cars by how new they are.
How to read these figures
Why the adjusted rate is the fair one
An unadjusted pass rate is strongly driven by the age and mileage of the cars being tested, not by how well they were built. A model bought mainly as a lightly used second car will look better than an identical car sold to high-mileage drivers. Adjusting for age and mileage compares each model against cars that have lived a similar life.
For a specific car, its own record beats any model average — check that vehicle’s MOT history and read what testers actually recorded against it.
