A truck-inspired bill in the Virginia state Legislature would prohibit trucks or cars from driving in the left lane of an interstate except to pass another vehicle.

Although the bill applies to both cars and trucks, sponsor Joe Johnson said he introduced the bill after driving behind three trucks, two in the right lane and one in the left, for 12 miles on I-81, according to The Roanoke Times.
The state already prohibits trucks from using the left lane of a three-lane road.
Some members of the House Transportation Committee say it will be hard to enforce - how do you prove that someone in the left lane is not attempting to pass another vehicle?
Johnson said that the publicity of the law would have an effect on safety, "putting a little fear into [truckers'] hearts and minds."
