MOT results in Inverness, 2025
Cars tested at stations in the IV postcode area, Inverness, had an initial MOT fail 31.5% of the time in 2025 once the age of the cars is allowed for (margin ±0.3 points, 143,020 tests), against 27.7% across Great Britain.

DVSA records the postcode area of the test station, not of the owner, so this describes where the test took place. It is part of our analysis of every 2025 MOT first test in Great Britain, which has the method, the models and the downloads.
The figures
| Measure | Inverness | Great Britain |
|---|---|---|
| Tests (class 4 first tests) | 143,020 | 33,210,823 |
| Initial fail rate, age-adjusted | 31.5% ±0.3 | 27.7% |
| Initial fail rate, as tested | 29.0% | 27.7% |
| Initial fail rate, age and mileage adjusted | 31.2% | 27.7% |
| Outright fails (a car fixed at the station counts as a pass), age-adjusted | 28.6% | 22.4% |
| Initial fails fixed and passed at the station | 9.4% | 19.0% |
| Tests with a dangerous defect | 6.3% | 7.3% |
Age-adjusted means the area’s cars are scored at the national rate for their age, so an area with an older fleet is not marked down for it. The age-adjusted national figure is the national rate itself.

Method and caveats, in short
Source: DVSA’s MOT anonymised data for all of 2025, every class 4 first test (33,210,823 in Great Britain), Open Government Licence v3.0. Initial fail rate = fail plus pass after rectification at the station, the figure DVSA publishes; outright fail = fail only. The age adjustment is indirect standardisation by age in whole years; the margin is 95%. Full definitions are on the main page.
- The MOT checks safety and emissions items, not the engine, clutch or gearbox, so this is one measure of how each car holds up rather than a full reliability verdict.
- A figure describes a model (or an area), not any one car. Two cars of the same model, age and mileage can be in completely different condition, so check the car in front of you.
- The analysis is observational. It shows that two groups differ, not why. Where the page offers a possible reason it says so, and it is a possibility.
- Regional differences may reflect how and where testing is done as well as the cars: whether a station repairs on site, the mix of stations and who books where. The figures describe where the test took place, not who owns the car.
