Spider 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) | 1 | 0% | 72.3 pts below |

| 11 years and over | 3,139 | 71.4% | 0.9 pts below |
Too few tests fall into some age groups to compare them reliably. The UK average of 72.3% covers cars of every age, so compare like with like.
