Drivers face £100 fine for a very common driving misdemeanour under Highway Code
YOU could be slapped with a fine for doing this common thing on British motorways under the new Highway Code.
The Code states that people shouldn't undertake other motorists on the road and that drivers could be hit with a £100 fine for doing so.
This comes as a series of new Highway Code rules have been introduced across the UK this year.
There is no specific law banning undertaking — overtaking a car on its left-hand side — but doing it recklessly could see you slapped with three penalty points and a hefty fine.
The penalty would be for careless driving, or driving without due care and attention.
of The Highway Code states: "In congested conditions, where adjacent lanes of traffic are moving at similar speeds, traffic in left-hand lanes may sometimes be moving faster than traffic to the right.

"In these conditions you may keep up with the traffic in your lane even if this means passing traffic in the lane to you right.
"Do not weave in and out of lanes to overtake."
Where traffic is congested and everyone is moving at similar speeds you may be able to undertake to keep up with traffic in your lane.
This is the case even if it means you pass vehicles in the lane on your right.
However, you shouldn't weave in and out of the lanes to get ahead.
What is undertaking?
Undertaking is when you overtake on the inside lane.
In the UK, that means passing the slower-moving vehicle on the left.
It is most common on motorways because there are more than one lane in the same direction.
Some drivers spend too long in the middle lane, which annoys others behind them.
