Millions of UK drivers are potentially risking fines and compromising road safety by regularly performing what they consider to be a polite gesture, according to the Highway Code.
The Everyday Gesture That Breaks the Rules
Most motorists won't realise they're doing anything wrong when they flash their headlights or hazard lights to say 'thank you' after being let out at a junction. This common practice happens daily on British roads, yet it directly contravenes the official rules of the road.
While in reality drivers are unlikely to face penalties for this well-meaning gesture, the Highway Code clearly states that headlights should only be flashed to let other road users know you're there. The code explicitly warns against using them to convey any other message.
Why This Common Practice Is Problematic
The reason highways authorities consider this a no-go area is the genuine risk of confusion and potential accidents. Someone might mistake your flash of lights as an invitation to proceed when it was actually meant for another driver entirely.
Jessica Potts, CMO at BookMyGarage, highlighted the issue, stating: "It's striking how many drivers admit to misusing their lights." She emphasised the importance of using hazard lights only to warn of a hazard, not to express gratitude in traffic.
Staying Safe and Legal on Winter Roads
As we move through autumn and into winter, proper use of vehicle lighting becomes increasingly important. Potts advised drivers to take a moment to familiarise themselves with their vehicle's controls, including dipped beam, full beam and fog-light switches, especially when driving a new or hire car.
The Highway Code provides clear guidance: "Never assume that flashing headlights is a signal inviting you to proceed. Use your own judgement and proceed carefully." While the friendly intention behind the gesture is understandable, sticking to the official rules helps ensure everyone's safety on increasingly busy and potentially hazardous winter roads.
