Motorists across the UK have been warned that a common gesture that many drivers make out of politeness could result in severe consequences, including an unlimited fine.

Despite the odd driver showing their arrogance behind the wheel, most Brits are polite around other road users, particularly those that help to let others into busy lanes or out of tricky junctions.

Julie Daniels, car insurance expert at Compare the Market, highlighted that these acts of kindness are typically followed by gestures which are meant to show that the driver is grateful.

She explained: “Being a courteous driver is about showing consideration and patience to others on the road. Small acts of kindness and understanding can help create a safer and more pleasant driving experience for everyone.”

However, one of the most common gestures made by drivers in the UK is actually against the law, putting them at risk of serious penalties.

When another road user has helped a driver, many Brits like to thank them by briefly turning on their vehicle’s hazard lights, which is widely seen as one of the easiest and safest ways to show gratitude.

However, according to Highway Code, drivers should only switch their hazard warning lights on when their vehicle is stationary in order to warn other road users that they have broken down or encountered an obstruction.

As a result, the friendly gesture could result in fines of more than £1,000 and up to nine licence points, particularly if the hazards confused another motorist nearby.

Whilst some of the gestures most commonly encountered on the roads could result in drivers facing serious complications, Compare the Market shared a number of ways motorists can still be kind to others without the risk of fines.

In particular, the company recommended that drivers always keep a safe distance behind the road users they are following, with tailgating often being seen as an intimidating experience and lead to serious accidents if the motorist in front has to stop suddenly.

Drivers were also urged to take care when nearby learner drivers, who often require more time, particuarly when negotiating junctions and pulling away from traffic lights and crossings.
