Common British driving habit could cost you £200

There’s a common habit among UK drivers that, although most would consider it common courtesy, is actually breaking the law. This one simple show of politeness could actually cost you £200 if you’re caught doing it.

Flashing your headlights to signal thank you, let someone go ahead of you, or even to warn of an upcoming speed camera is illegal in the UK. Drivers who flash their lights to warn others of police presence face potentially devastating penalties of up to £1,000 for obstructing police duties.

Highway Code Rule 110 states that drivers should "only flash your headlights to let other road users know that you are there."

It explicitly warns: "Do not flash your headlights to convey any other message or intimidate other road users."

How much you are penalised depends on the reason why you flashed your lights.

For ‘general misuse’ such as giving way or saying thank you, you can be fined between £100 and £200 and issued three to six penalty points due to careless driving.

However, if you are warning of speed cameras, or police cars, then the fine can climb as high as £1000 and you could face prosecution for "wilfully obstructing a constable" under Section 89 of the Police Act 1996.

Car finance expert and owner of Simple PCP Claims, Tom Riley said: "Most drivers flash their lights with good intentions, thinking they're being helpful.

"But the law is crystal clear, you can only flash your headlights to alert others to your presence. Anything else could technically land you in hot water.

"The £200 fine might not sound enormous, but add penalty points and you're looking at a serious hit to your driving record.

"For drivers who warn others about speed traps, that £1,000 maximum penalty could be financially devastating.

"The safest approach is simple, only flash when you genuinely need to alert someone to your presence."
