A new law has been introduced in the US state of Kansas banning motorists from hogging the fast lane.
It is now illegal to use the far left lane of multi-lane highways except when passing, turning left, or when instructed to by police officers.
The so-called Right Lane Law was introduced last month and it is thought other states could follow.
The law is designed to prevent motorists from performing risky manoeuvres and will help reduce road rage, says Trooper Mark Engholm of the Kansas Highway Patrol.
Recently Autocar launched a campaign to improve driving standards in the UK, including teaching better lane discipline.
A survey of more than 14,500 motorists released as part of the campaign found that tailgating is the habit that most annoys drivers in the UK.
