Is the Rx getting worse?
The fail rate rose 1.2 points to 6.1% from 2022 to 2025 while the median one tested aged 2 years. Ageing alone would predict about 4.2 points, so it is holding up better than the fleet average for its age.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 12,054 | 5 | 4.9% | 22.5% | |
| 2023 | 13,404 | 6 | 5.1% | 22.8% | |
| 2024 | 12,369 | 6 | 5.7% | 23.2% | |
| 2025 | 15,063 | 7 | 6.1% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Rx at its test that year, and it is the number to watch: across the whole fleet each extra year of age adds roughly 1.9 points to the fail rate, so a model whose age and fail rate rise together is simply getting older.
The exact defects that fail it
Every failure item DVSA recorded against a Rx in 2025, counted by how many tests each one appeared on.
- 1Condition: has a cut in excess of the requirements deep enough to reach the ply or cords171 tests
- 2Tread depth: tread depth below requirements of 1.6mm160 tests
- 3Brake pads: less than 1.5 mm thick145 tests
- 4Condition: has ply or cords exposed113 tests
- 5Wipers: does not clear the windscreen effectively108 tests
- 6Linkage ball joint dust cover: ball joint dust cover no longer prevents the ingress of dirt82 tests
- 7Position lamp: not working67 tests
- 8Tyre pressure monitoring system: malfunctioning or obviously inoperative67 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Rx collects 2.39 of them per test, and these are the ones that come up most. Treat it as the running-repairs list for the next year or two.
- 1Tread depth: tread depth below requirements of 1.6mm2,505 tests
- 2Pins and bushes: pin or bush excessively worn1,630 tests
- 3Condition: has a tear, caused by separation or partial failure of its structure1,107 tests
- 4Brake pads: less than 1.5 mm thick1,001 tests
- 5Brake discs: in such a condition that it is seriously weakened848 tests
- 6Tread depth: tread pattern not visible over the whole tread area when minimum depth required is 1.0mm385 tests
- 7Condition: has a cut in excess of the requirements deep enough to reach the ply or cords308 tests
- 8Non-component advisories: Child Seat fitted not allowing full inspection of adult belt290 tests
