They explained: “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.”

Car insurance experts and breakdown specialists at the RAC also stressed that flashing headlights “inappropriately” could be a problem. 

They added that road users should never try to intimidate” an individual through flashing their lights. 

Meanwhile, they urged individuals to be careful with scammers taking advantage of the button to purposefully crash into vehicles. 

The RAC added: “Importantly, we should never make the assumption that another driver flashing their headlights is a signal inviting us to proceed. 

“We’ve all heard of ‘flash for cash’ scams. Use your best judgement and proceed carefully.

BigWantsYourCar stressed that incorrectly using headlights could become a severe safety hazard, 

They have encouraged road users to “routinely check” that the tool is “functioning properly and correctly aligned”. 

Lights which are not working as intended could “unintentionally dazzle” other road users which risks creating “dangerous driving conditions”.

The Highway Code reads: “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.”
