MOT History Check Guide: How to Read a Car's MOT Record
Every car over three years old in the UK must pass an annual MOT test. The DVSA publishes every test result online for free — and those records are a goldmine of information for used car buyers. Here is how to use them.
Where to Find MOT History
The DVSA runs a free online MOT history service at check-mot.service.gov.uk. You only need the vehicle's registration number. The service shows every MOT test the car has had — passes, fails and advisories — going back to 2005 for digital records, and earlier for some vehicles.
Motovo's car check service also includes MOT history alongside other useful data like ULEZ status and road tax rates.
What to Look For in an MOT Record
Mileage Trends
The MOT record shows the mileage at each test. Plot it out in your head — does it rise steadily by 8,000–12,000 miles a year? A sudden drop or a flat line is suspicious and could indicate clocking. Equally, an unusually high annual mileage may mean the car was used for commercial purposes like deliveries or taxi work.
Recent Failures
A car that fails its MOT is not necessarily a bad car — especially if the failure was for something simple like a blown bulb or worn wiper blades. But look at what it failed on. Major failures on structural items like corrosion, suspension or brakes are worth investigating. If the car has failed multiple times on the same issue, it may point to poor ongoing maintenance.
Advisories (Minor Issues)
Advisories are items the tester noted but that were not serious enough to fail the test. Common examples include slightly corroded brake pipes, worn but legal tyres, or a small oil leak. A few advisories on an older car are normal. But look for recurring advisories that appear year after year — they suggest the owner deferred maintenance rather than fixing issues.
The Clean Pass
A car that has passed every MOT first time, with no advisories, for several years running is a strong sign. It usually means the owner has kept on top of maintenance and resolved issues before the test, rather than waiting for them to become failures.
Red Flags to Watch For
- !Structural corrosion. Any failure or advisory mentioning corrosion on "prescribed areas" — such as suspension mounts, seat belt anchorages or subframes — is serious. These are safety-critical and expensive to repair.
- !Brake pipe corrosion. Common on older UK cars. If it recurs in the MOT history without being fixed, budget for replacement brake pipes.
- !Missing MOTs. Gaps in the MOT record — where no test was recorded for a year or more — could mean the car was off the road (SORN), but they can also hide damage or a period of neglect.
- !Emissions failures. If a car repeatedly fails on emissions, it could have an underlying engine or catalytic converter problem that is expensive to fix.
MOT History Quick Checklist
Why Use the Motovo Car Check for MOT History?
You can check MOT history for free on the DVSA website — but interpreting years of test results takes time, and repeated advisories are easy to miss. The Motovo Car Check brings MOT history together with ULEZ status, tax data and HPI-backed vehicle insights in one place, with a Key Observations summary that helps you spot what matters.
- Full MOT history with pass/fail records and mileage at each test
- Repeated advisories highlighted so you can see patterns at a glance
- Mileage trends checked for unusual drops or gaps
- ULEZ compliance, road tax rates and DVLA data alongside MOT records
Key Observations — Spot Patterns Without the Scrolling
MOT history can stretch across a decade or more — long lists of advisories make it difficult to spot what really matters. Motovo's Key Observations summary pulls important points to the top: repeated advisories on the same component, unusual mileage patterns, recent failure reasons and structural concerns. It gives you a clearer starting point before you message a seller or visit the car.
Use the Report When Viewing the Car
Take your Motovo Car Check report with you to the viewing. Use the Key Observations as a practical checklist:
- If repeated brake advisories appear, check the brakes carefully and ask for repair invoices
- If tyres appear repeatedly in advisories, inspect tread depth, condition and matching brands across all four wheels
- If MOT mileage jumps look unusual, ask the seller to explain and provide supporting service records
- If structural corrosion was noted, inspect the underside or get a professional opinion before buying
How Motovo Can Help
The Motovo Car Check combines MOT history, ULEZ status, tax data, DVLA information and HPI-backed vehicle insights into a clear report. The Key Observations section helps summarise important points, such as repeated advisories, mileage patterns and other issues worth checking before you view or buy.
