A Tyre Pressure Monitoring System (TPMS) is a safety feature in modern vehicles that monitors the air pressure inside the tires. It alerts the driver if a tire is underinflated, which can help prevent accidents, improve fuel efficiency, and prolong the lifespan of the tyres. ‌ Daniel Croft, an expert driving instructor who has collaborated with the private registration plate firm Number 1 Plates, highlighted that motorists should avoid setting off if their tyre pressure monitoring system (TPMS) warning light is on. ‌ READ MORE UK faces first snow of April with flurries and -7C 'lasting three days' He explained: "People see it and think, ‘I’ll deal with it later’. But low tyre pressure affects everything how your car brakes, how it handles corners, even your fuel use. In the worst case, it can lead to a blowout at high speed. ‌ "One of my ex-learners, Emma, rang me in a panic after her tyre gave out while joining the M62. She thought it was just a small air drop and didn’t check it. Luckily she wasn’t hurt, but it shook her up badly." They added: "It’s easy to brush off warning lights as just another annoying beep, but they’re usually trying to tell you something important. We’ve had customers admit they ignored their tyre pressure light for weeks only to end up with a flat or a failed MOT. "The TPMS light is one of those things people forget about, but it’s directly tied to your safety. A quick five-minute check could save you a lot of hassle or even prevent something far worse down the line."

It's important to regularly maintain tire pressure to ensure safety and efficiency.
