4.3 million cars driving without valid MOTs

12th March 2026

New data has found that millions of vehicles in the UK could be driving illegally after missing their MOTs.

According to Kwik Fit, the MOTs of 4.3 million cars were allowed to expire last year. About half were booked within 10 days of the expiry date, but many were left much longer with the average lapse between expiry and test recorded at 33.7 days.

In addition, a further 1.7 million tests were booked before the MOT ran out but tested afterwards.

Meanwhile, the DVSA has found that more than a quarter of cars (27%) fail their MOT, meaning that over 1.5 million vehicles without a valid MOT are also not roadworthy.

Dan Joyyce, who heads up Kwik Fit’s MOT programme, said: “The MOT test may sometimes feel like a chore for drivers but it is essential in ensuring a car is safe and roadworthy. We all lead very busy lives and it is all too easy for the MOT to slip down the to-do list.

“But the consequences of booking the annual test too late are significant; there is the risk of a fine of up to £1,000, but more importantly, the potential to be driving a dangerous vehicle.”
