How to Read a Car’s MOT History (and Spot Mileage Red Flags)

• MOT results back to 2005 are free to check on GOV.UK with only the number plate, so a buyer can read a car’s passes, fails and mileage before leaving the house.
• Three patterns give a car away: a mileage reading that drops or stalls, the same advisory repeated test after test, and a missing year between tests.
• A pass covers one test on one day and says nothing about finance, write-offs or the engine, so the history is the first check, never the last.

Type the Plate Into GOV.UK Before You Book a Viewing

Go to the GOV.UK page for checking the MOT history of a vehicle, press Start now and type the number plate. The service asks for nothing else. It returns every test result for the car back to 2005, whether it passed or failed, the mileage recorded at each test and the date the next MOT is due. Depending on the maker, it also shows whether the car has been recalled for a safety reason.

A test done in Great Britain gives you more. The page offers downloads of the current and earlier certificates, lists the parts that failed at each test and flags those with minor problems. A test done in Northern Ireland only appears from 2017 and the certificate cannot be downloaded.

A result appears only after the test centre uploads it, so a car that passed this week can take a few days to show. A seller who says the car passed yesterday and a page that shows nothing is a reason to ask for the paper certificate, not to walk away. Run the check at the advert stage. It costs nothing, it takes a few minutes, and it decides whether the car earns a viewing or a full vehicle history check.

What Each Line of the Result Means

A failed test shows the word fail in large red letters, with the reasons listed underneath. A pass shows in green. Under a pass sit the advisories, the defects a tester noted that were not bad enough to fail: worn tyres close to the legal limit, worn brake pads and corrosion are the common ones. No advisories means a clean pass.

Each entry is a snapshot of what the tester checked that day: lights, brakes, tyres and wheels, steering and suspension, exhaust and emissions, bodywork and structure, windscreen and wipers, seat belts, number plates and the VIN, and the fuel system. The test costs up to £54.85 (about $73 at 1.34 dollars to the pound), VAT is not charged and it usually takes under an hour. Every owner pays that bill each year, so a tester’s notes are a cheap and regular record of how a car has aged.

A fail followed by a pass a few days later points to a repair. Read the failure reasons to learn what was fixed, then ask for the invoice.

The Mileage Maths

Each test records the odometer reading, and the gaps between readings should look like one driver’s life. Take an invented car that covers about 7,000 miles a year. Readings of 42,000, 49,100 and 56,000 at three consecutive tests give gaps of 7,100 and 6,900 miles. That is a steady pattern.

Now the next reading. If it is 56,400, the gap is 400 miles. A car can cover that little in a year, after a long illness, a spell abroad or months waiting for a repair, so the figure is a question for the seller, not a verdict. If the next reading is 49,000, the odometer shows 7,000 miles fewer than the test a year earlier. A working car cannot lose miles. Either the tester mistyped the figure, which GOV.UK lets you report under its report a mistake on your MOT record link, or the dial was wound back. A car that has hardly been used for years and then racks up excessive miles in a short period deserves the same question.

Check the present dashboard reading against the last test as well. Say the last test read 56,000 eight months ago. At 7,000 miles a year the car covers about 583 miles a month, so eight months adds about 4,667 miles and the dashboard should show near 60,700. A dashboard showing 56,300 means 300 miles in eight months, and a dashboard below 56,000 is the clearest red flag in the whole record. Ask to see the service book too: the stamps and invoices in it should back up the mileage. The guide to spotting a clocked car covers what to do if the numbers still do not add up.

Repeat Advisories and Gaps in the Record

Read the advisories across several tests, not one. The same advisory in 2023, 2024 and 2025 means three owners or three years of putting off a job. An advisory that turns into a failure is worse: the problem was named, left alone and then grew until it stopped the car passing. A buyer inherits that neglect.

Outstanding advisories also give you a lever. If the latest pass lists a tyre or a brake pad advisory and the seller has no invoice for the work, get a quote from a garage for the job and take that sum off the asking price. A seller with receipts has fixed the problem. A seller without them has handed you the bill.

Then count the years. A car must be tested by the third anniversary of its registration and then by the anniversary of its last MOT, and an MOT lasts a year. Some vehicles need a test at one year old, which GOV.UK lists in its fees table. So a car should show one entry for each year after its first test, and a missing year suggests it ran without a valid MOT or sat off the road. Driving without a valid MOT carries a fine of up to £1,000 (about $1,340), and the only exceptions are a drive to a repair or to a pre-arranged test. A test can happen up to a month (minus a day) early and keep the same renewal date, so dates that fall a few weeks short of a year apart are normal.

If you own the car or the seller hands over the V5C, the 11-digit number in the log book shows where each test was done. Ask the seller to explain a test at a garage far from home. A keeper who has lost the log book can follow the steps to replace a lost V5C log book before the sale.

What the New MOT Photo Rule Does and Does Not Do

On 3 August 2026 DVSA began a national rollout of Photos at Test. The first wave covered about 2,500 garages in Great Britain, which now have a feature that lets a tester photograph the car in the testing bay and upload the image to the MOT system. The photo has to show the vehicle in the bay with the number plate completely legible. DVSA wants it to deter fraud and to cut the risk of a certificate being issued when the car is not at the test station. That practice is a ghost MOT: a pass handed out with no full inspection, or with no car at the garage at all.

Across the trial phases, more than 300 garages uploaded over 60,000 images with a 92 per cent success rate, and initial tests stayed at around 40 minutes. Grant Thunders, Head of MoTs at the DVSA, set out the aim: “Photos at Test will help prevent fraud, provide reassurance to motorists, and protect the reputations of hard working and honest MoT testers across the country.”

Thunders added: “This change adds to the range of intelligence and evidence-gathering processes used by DVSA to tackle MoT fraud,” he continued, “and will help us to take action against anyone who attempts to undermine the integrity of the MoT or compromise road safety.”

For a buyer the rule has limits. DVSA says taking the photo is currently voluntary and has set no date for making it compulsory. The history page lists no photo. A recent pass does not prove the car was inspected, and an older pass is not automatically suspect. Treat the rule as pressure on ghost testing and nothing more, and keep checking the mileage and advisory pattern against the car and its service book.

What the Record Cannot Tell You

The history lists tests, mileage, the next due date and any recall. It is not a check for outstanding finance or a write-off past, and neither shows up however clean the passes look. The guide to checking a used car for hidden finance covers the next step, and a full vehicle history check closes the gap.

A pass also says nothing about the car on any other day, and the months after a test wear tyres and pads again. Use the history to decide what to ask: why the mileage dropped, who fixed the advisory, where the missing year went. Then check the dashboard against the last test, read the service book and view the car in daylight. A seller who answers every question with a receipt has earned the deposit. A seller who cannot has told you what to do next.
