Almost a quarter of drivers risk being fined up to £1,000 for driving without a valid MOT, putting fellow road users and Britons in danger on UK roads.
New research has revealed that millions of cars are already on the road with overdue MOT tests, operating unsafe vehicles.
Figures released through Freedom of Information requests to the DVSA showed that 2.9 million vehicles were driven without a valid MOT over the past three years.
If every driver had been caught and fined for not having an MOT, the total bill could reach around £3billion.

The research, carried out by Confused.com, found that more than one in five motorists have admitted to missing their MOT date at least once.
Worryingly, over half of these drivers said that this has happened more than once, prompting motoring experts to raise serious safety concerns.
The problem varies across the country, with the South East having the highest number of overdue tests between 2022 and 2024, with more than 433,000 cars on the road without a valid MOT.
In 2024 alone, around 791,000 cars nationwide were past their MOT due date, with London seeing the highest number of overdue MOTs in a single region last year at 277,745, despite also having the highest test pass rate at 78 per cent.

Overall, the national pass rate for MOT tests in the last three years was 72 per cent, meaning more than a quarter of vehicles failed.
The South West had the lowest pass rate at 67 per cent, while Northern Ireland recorded the highest pass rate of all at 81.5 per cent in the last financial year.
When asked why they missed their MOT, nearly half of drivers said they simply forgot, with one in seven believing that they had more time left than they actually did.
A further seven per cent said they couldn't get a garage appointment in time, while some drivers also pointed to rising costs, with almost one in 10 delaying their test because they couldn't afford it. The average amount drivers say they spend on an MOT, including repairs, is £111.

| PAThe survey also found growing frustration with the MOT system, with more than one in six drivers thinking MOTs should only be required every two years to reduce costs.
More worryingly, one-fifth of drivers shared that they suspect some garages fail vehicles unnecessarily to make money from repairs.
The data also highlighted the most common reasons for MOT failures. Brake issues top the list, with more than 27 million failed tests since 2022, marking around nine million a year.
Suspension faults were the second most common problem and can cause cars to skid or swerve. Worn tyres came in third, posing a major safety risk, especially in poor weather.

| PAIn the UK, the penalties for driving without a valid MOT can be severe, with most drivers facing a fine of up to £1,000; however, this can rise to £2,500 if the car is deemed to be dangerous.
Police can also issue three penalty points, and in serious cases, drivers could be banned from driving and have their car insurance invalidated.
Rhydian Jones, motoring expert at Confused.com, said the findings should act as a wake-up call. He warned that an MOT is not "just a box-ticking exercise", but a crucial way to ensure a car is safe.
"Millions of cars are on the road without a valid MOT, often because drivers forget," he said. "But it's not just the fine that matters – your insurance could also be at risk."
