A recent survey has exposed a worrying gap in driver knowledge.

As technology used in vehicles continues to evolve at pace, motorists are increasingly left in the dark by the warning lights.

The new survey reveals that 91% of UK motorists are unable to correctly identify all dashboard warning lights in their vehicles.

Conducted by Tempcover, the survey of 2,000 UK drivers found that nearly four in ten (39%) couldn’t correctly identify the engine warning light — one of the most critical indicators of a potential fault under the bonnet.

Even more alarmingly, 22% of respondents admitted to continuing to drive with the engine warning light illuminated, and 37% said they waited a week or longer to have it checked.

These findings aren’t entirely new but show that the problem of dashboard confusion persists despite years of similar warnings.

In a 2016 survey by the RAC, 98% of drivers failed to recognise all dashboard symbols, suggesting that little progress has been made in the past decade when it comes to improving driver literacy around in-car systems.

Can you see what it is yet?

The new data paints a picture of continued driver ignorance that could be putting road users at risk.

Warning lights are not just minor notifications — they are part of a vehicle’s onboard safety and diagnostics systems, designed to alert the driver to immediate or impending faults that may affect performance or safety.

Among the most commonly misunderstood symbols were the Electronic Stability Programme (ESP) light (73% failed to identify), Diesel Particulate Filter (DPF) warning (62%), and Tyre Pressure Monitoring System (57%).

These systems play crucial roles in preventing skidding, managing emissions, and maintaining safe tyre function — yet the majority of drivers don’t recognise their alerts.

Claire Wills-Mckissick of Tempcover stressed the dangers of ignoring warning lights. “If the engine warning light comes on, it’s important not to ignore it.

If the light is flashing or red, you should stop immediately and seek assistance,” she said. “Dashboard lights often indicate safety-critical issues that require swift action.”

Alternative meanings

The survey also revealed that the top reasons drivers continued to drive with an illuminated warning light were the belief that it wasn’t serious or urgent (29%) and a lack of noticeable impact on the car’s performance (23%).

Disturbingly, 10% admitted they didn’t understand what the light meant at all.

The issue is symptomatic of a wider trend: while cars are becoming increasingly sophisticated, driver training and awareness are not keeping pace.

Today’s vehicles are equipped with complex safety and emissions systems, yet many motorists have little understanding of how they work or how to respond to system alerts.

Behind the wheel

Experts are now calling for a revamp of driver education to include more thorough instruction on modern car technology.

They believe that a basic understanding of dashboard lights should be reinforced not just at the point of obtaining a licence, but through ongoing public awareness campaigns and dealership-led customer education.

Some of the latest driver assist technology, such as automated emergency braking (EBD), intelligent speed adaption (ISA)  or lane departure warning (LDW) should require dealership training options to ensure drivers understand the benefits of and how to correctly use the new systems.

As Wills-Mckissick concluded, “Drivers need to understand what their car is telling them. Recognising dashboard symbols is not just about protecting your vehicle — it’s about protecting lives.”

Without greater efforts to educate drivers on what these warnings mean and how to respond, the technological safety benefits of modern vehicles may continue to go unrealised — and more dangerously, ignored.
