Drivers across the UK are being cautioned that flashing their headlights to warn others about speed cameras could result in a significant fine.
Motorists who do this risk penalties of up to £1,000, and in some cases may also receive points on their licence.
Under Highway Code Rule 110, using headlights to signal anything other than your presence on the road is prohibited. Police and enforcement officers are increasingly clamping down on drivers who use this gesture to alert others to speed traps.
Experts at Pure Digital PR noted that many drivers are unaware that this common habit is illegal and can lead to unexpectedly serious consequences.
The situation happens frequently: a driver spots a speed camera or police speed check and flashes their lights to warn oncoming traffic. While the gesture may seem harmless, it is officially classified as obstructing police duties.
“Many motorists think they’re doing someone a favour by helping them avoid a ticket, but they’re actually disrupting police efforts to deter dangerous driving,” the specialist explained.
Rule 110 clearly states that headlights should only be flashed to signal your presence. It also warns: “Do not flash your headlights to convey any other message or intimidate other road users.”
This makes it clear that using headlights to warn others about enforcement activity is not permitted, despite how common the practice may be.
According to experts, headlights are strictly a safety tool—not a means of signalling police activity.
Drivers who misuse their headlights could face fines of up to £200 and penalty points. In more serious cases where the behaviour is considered intentional interference with police work, penalties may rise to £1,000, and motorists could even be prosecuted for obstruction
A seemingly friendly gesture could therefore end up costing drivers dearly, both financially and on their driving record.
