Motorists could be fined up to £1,000 for engaging in a common driving behaviour. While flashing headlights is a common way for motorists to communicate with each other while driving, it is a violation of the Highway Code and comes with a steep penalty if caught.

Experts at BigWantsYourCar warn that the Highway Code is clear that headlights should only be used to let other drivers know you are there. A spokesperson for the car-selling site said: “By flashing your headlights to signal other road users, drivers are not only breaking the rules but also risking their safety. Improper use of headlights can lead to confusion on the road, making situations more dangerous.”

The Highways Code states: “Only flash your headlights to let other road users know that you are there. Do not flash your headlights to convey any other message or intimidate other road users.”

The spokesperson added” “Flashing headlights is commonly used by drivers to signal other motorists, but many are unaware that this practice can land them with a substantial fine. The Highway Code is clear: headlights should only be used to let other road users know you are there, not for signalling purposes such as warning of speed cameras or other hazards. Misusing them can be considered an obstruction to the police, which carries the risk of a £1,000 fine.”

To avoid this fine, motorists need to be aware of Rules 110 and 111 of the Highway Code, which state that headlights must not be flashed to convey messages or signal other drivers. Failing to adhere to the Highway Code can have serious consequences.

According to Section 89 of the Police Act 1997, motorists can face legal action if they obstruct a police officer in their duties. Drivers may not be aware that alerting others to speed checks or police presence by flashing their headlights can be considered an obstruction, potentially resulting in fines or even a court appearance. To avoid issues, BigWantsYourCar advises drivers to strictly follow the Highway Code.

“Motorists should never use their headlights to signal other drivers, as this could lead to misinterpretation and accidents. The best course of action is to always ensure that your headlights are used solely to maintain visibility and follow the rules to avoid unnecessary fines,” a spokesperson said.
