Can the police start acting on this? It is the law. It would stop road rage.
Colorado Statutes 42-4-1013 says, “A person shall not drive a motor vehicle in the passing lane of a highway if the speed limit is 65 mph or more unless such person is passing other motor vehicles that are in a nonpassing lane or turning left, or unless the volume of traffic does not permit the motor vehicle to safely merge into a nonpassing lane. ... For the purposes of this section: ... Passing lane means the farthest to the left lane if there are two or more adjacent lanes of traffic moving in the same direction in one roadway; ... A person who violates this section commits a class A traffic infraction.”
