Drivers who make common mistake could face large fine - key warning issued

Motorists who flash their lights to warn others about speed cameras may think they're being helpful, but they are actually contravening traffic laws and could face a hefty fine. The Highway Code's Rule 110 clearly states the guidelines for flashing headlights: "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." In addition, section 89 of the Police Act 1997 makes it an offence to obstruct a police officer in the execution of their duties, which includes actions such as headlight signalling, carrying a potential fine of up to £1,000.

This is significantly more than the minimum fine for speeding caught on camera, which is £100 and three points on your licence. Yet drivers continue to use headlight flashes to signal the presence of mobile speed cameras, risking penalties, North Wales Live reports.

There have been cases, like one in 2011, where motorists faced legal consequences for this exact behaviour. A driver in the north-east of England was fined £175 for attempting to warn other motorists about safety, ending up in court. The individual was also ordered to pay £250 in costs and a £15 victim surcharge.

The Highway Code has stringent guidelines on signalling to other drivers, with Rule 110 stating that there's rarely an appropriate time to flash your lights. Rule 111 further cautions, "Never assume that flashing headlights is a signal inviting you to proceed. Use your own judgement and proceed carefully."

Additionally, Rule 112 clearly dictates the use of the car horn: "Use only while your vehicle is moving and you need to warn other road users of your presence. Never sound your horn aggressively. You must not use your horn except when another road user poses a danger."
