UK drivers are being warned they could face fines of up to £5,000 for the incorrect use of their hazard warning lights, with a new survey revealing that one in four motorists admits to this common offence.
Widespread misuse of vehicle lights
A study conducted by BookMyGarage, which surveyed 2,000 UK drivers, uncovered startling habits on British roads. The most frequent transgression involves drivers using their hazard lights inappropriately, often simply to "say thanks" to other motorists.
The research, highlighted in November 2025, identified additional concerning behaviours. One in seven drivers confesses to driving with broken or dirty headlights or brake lights. Even more remarkably, a significant 13 per cent of motorists admit they have failed to use their fog lights in foggy conditions because they couldn't locate the control.
Financial and legal consequences
While most lighting offences typically result in a £50 fixed penalty notice without points, the consequences can be far more severe. If police determine the misuse constitutes careless or inconsiderate driving, offenders could face a £1,000 fine and three penalty points on their licence.
In the most serious cases, the matter may be taken to court, where magistrates have the power to impose maximum penalties of up to £5,000, between three and nine penalty points, and even driving disqualification.
Expert advice for safer driving
Jessica Potts, Chief Marketing Officer at BookMyGarage, commented on the findings: "It's striking how many drivers admit to misusing their lights. As we move through autumn and into winter, mud and spray quickly dull headlamps and number plates, so regular cleaning matters, but so does confidence with the controls."
She offered practical guidance for all motorists: "Before any journey, especially in a new or hire car, take a moment to locate dipped, full beam and fog-light switches. Use fog lights only when visibility is seriously reduced, and reserve hazard lights for warning of a hazard, not to say 'thank you' in traffic."
Potts also emphasised the importance of regular winter checks at a local garage to ensure lights are functioning correctly and vehicles are prepared for colder conditions. "But, there is no harm in the meantime doing a quick walk-around yourself, checking your car headlights, brake lights and fogs, as it can make all the difference on dark, wet roads at this time of year," she added.
