300 MOT pass rate by age
The same 2025 tests split by the car's age at test.
| Age at test | Tests | Pass rate | vs UK average |
|---|---|---|---|
| 3 to 5 years (small sample) | 2 | 100% | 27.7 pts above |
| 6 to 10 years (small sample) | 36 | 75% | 2.7 pts above |
| 11 years and over | 3,436 | 64.9% | 7.4 pts below |
