National Highways research estimates 4.5 million UK drivers missed or delayed their last MOT test. Of these, around 1.6 million are believed to have driven without a valid MOT certificate.
One in ten drivers miss MOT deadlines
The study surveyed UK driving licence holders and found that 11% failed to take their annual MOT on time. Driving without a valid MOT is illegal except when travelling directly to a pre-booked MOT appointment.
Despite this, almost a quarter of those who missed the MOT date said they considered their vehicle safe to drive. This contrasts with the Driver and Vehicle Standards Agency’s (DVSA) advice that delaying an MOT increases the likelihood of defects, potentially compromising safety.
Checks become vital as autumn approaches
Colin Stevenson, Road Safety Information Lead at National Highways, highlights the heightened risk in autumn. Shorter daylight hours, wetter roads and lower temperatures increase demands on vehicles and drivers alike.
He urges motorists to follow simple preparation steps before setting off. These include checking tyres, lights, and fluid levels to help reduce breakdowns and improve safety. Staying on top of MOTs and routine maintenance can reveal defects early, preventing costly and dangerous problems.
MOT and maintenance: separate but connected
While MOT testing is a legal requirement for vehicles over three years old, regular servicing remains the driver’s responsibility. Routine maintenance identifies issues that may not appear at the MOT but affect safety.
National Highways research highlights that 57% of tyres on UK roads are underinflated by at least 4 PSI. Underinflation increases fuel consumption, tyre wear and road noise. Correct tyre pressures could prevent more than 500,000 tonnes of greenhouse gas emissions annually on England’s motorways and major A roads.
Free MOT reminders support compliance
Grant Thunder, Head of MOT at the DVSA, stresses the MOT ensures vehicles meet minimum safety and emissions standards at the test date. He advises drivers to maintain their vehicles year-round and take advantage of the DVSA’s free MOT reminder service to avoid forgetting deadlines.
With changing weather and road conditions ahead, National Highways recommends that all drivers verify their vehicle’s roadworthiness before journeys. This reduces risks for drivers, passengers and other road users.
