- Fail rate
- = the share of MOT tests that ended in a fail. Retests count as tests.
- Fail, no pass in 3 days
- = the share of MOT tests that failed and still hadn't passed 3 days later. A fail that passed a retest within 3 days, even the same day, isn't counted.
- Dangerous
- = the share of MOT tests where the tester marked a fault as dangerous. It is against the law to drive the car until it is fixed.
- Still registered at 10 years
- = the share of cars still registered (taxed or declared off the road) 10 years after they were first registered.
