Millions of drivers do this every day and don't they are breaking the Highway Code

It's something that happens on the roads up and down the country every day. But millions of drivers don't know they're actually breaking road rules.

One of the most commonly misunderstood Highway Code rules states drivers shouldn't flash their headlights for any other reason than to let other motorists know they are there. It's common for drivers to flash their headlights for other reasons, usually to give way to another vehicle waiting to turn in or out of a junction.

It's also a common way to thank another motorist for a good turn. Another time headlights are used is to warn other drivers of speed cameras or police vans up ahead.

This is particularly frowned upon by police and could result in motorists being fined. A recent survey by insurance firm Tempcover found a huge 60% of drivers were unaware this was against the Highway Code, making it one of the most little-known rules.

Meanwhile, almost three quarters (73%) didn't know beeping the horn while stationary was also a Highway Code breach. Nearly half (44%) were unaware littering from a car was an offence.

Claire Wills-McKissick, motoring expert at Tempcover, said: "The winter period often brings increased traffic and challenging weather, which can lead to unexpected risks on the road. Simple mistakes like not mounting your sat-nav properly, flashing your headlights to warn others of speed cameras, or even using your horn when stationary can lead to fines and unexpected penalties.

"There are a few ways to stay safer on the roads. Set up your sat-nav correctly, avoid distractions, and make sure you know the ins and outs of the car you’re driving."
