Motorists across the UK should be cautious this winter as they face the risk of a £50 fine for incorrectly using fog lights, a rule that many drivers may overlook. Although fog lights can be important for safe driving in limited visibility, misusing them can lead to fines.

“Fog lights are designed specifically to increase visibility during extreme weather conditions, especially when fog or heavy mist reduces vision to less than 100 metres,” said a spokesperson at Motor Match. “However, using these lights in clear conditions can be more of a hazard than a help. The intense brightness of fog lights can dazzle other road users, obscure brake lights, and lead to confusion or even accidents. That’s why the Highway Code has clear rules on when to use them – and why failing to follow those rules can result in fines.”

The Highway Code’s Rule 236 states: “You must not use front or rear fog lights unless visibility is seriously reduced.” This guidance is straightforward, yet some drivers may leave their fog lights on during light drizzle or clear conditions, unaware of the risk this poses to other motorists. As well as posing a safety risk, poor fog light use can cost drivers £50 in fines, a penalty that may come as a surprise to those who are unaware of the regulation.

“At Motor Match, we encourage drivers to stay informed about vehicle safety and to adopt good driving habits as we enter the foggy autumn season,” the spokesperson adds. “When fog lights aren’t needed, they should be turned off immediately.”

While a £50 fine may not seem like much, it’s an added cost for drivers who may already be feeling the pinch from rising expenses. Following this simple rule can avoid these unnecessary penalties, especially since there are no penalty points associated with fog light misuse—only fines.

“Fog light rules might seem minor, but they’re important for road safety,” the spokesperson from Motor Match continues. “By limiting fog light use to times when visibility drops below 100 metres, drivers can prevent unnecessary distractions or safety risks.”
