Little-Known Highway Code Rule: Flashing Your Car Headlights Could Land You in Trouble
Flashing headlights warning could land drivers in trouble

Motorists across the UK could be unknowingly breaking the law by using a common driving practice – flashing their headlights to alert other road users about speed cameras. While many see it as a courteous gesture, this act is actually prohibited under the Highway Code and could lead to serious consequences.

The Legal Consequences

According to Rule 110 of the Highway Code, drivers must not use their lights to 'convey any other message'. This includes warning other motorists about speed traps or mobile camera vans. Those caught doing so could face:

  • A £1,000 fine
  • Three penalty points on their licence
  • Potential prosecution for obstructing justice

Why Is It Illegal?

Police and road safety experts argue that flashing headlights to warn about speed cameras undermines road safety efforts. Speed limits are put in place to protect all road users, and alerting speeding drivers allows them to avoid detection and continue driving dangerously.

What the Highway Code Says

The official guidance states: '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.'

Alternative Ways to Improve Road Safety

Rather than warning speeding drivers, motorists can contribute to safer roads by:

  1. Always observing speed limits
  2. Reporting dangerous driving to authorities
  3. Setting a good example for other road users
  4. Supporting community speed watch programs

With increasing numbers of mobile speed cameras being deployed across the country, it's more important than ever for drivers to understand the proper use of headlights and comply with all Highway Code regulations.
