A driver who knows only red lights may not pull over for a patrol car showing amber.

Montana's move-over rule applies on highways with a posted speed limit of 50 mph or more, in the lane next to a stationary emergency or police vehicle showing emergency signals.

At highway speed a car that does not slow passes inches from people working beside the road.

On highways with a posted speed limit of 50 MPH or more, vehicles in a lane directly next to a stationary emergency or police vehicle displaying emergency signals must slow down to a speed of at least 20 miles below the posted speed limit.

In the lane next to a stationary emergency or police vehicle with signals on, slow to at least 20 mph below the posted limit.

An officer standing at a car door has no room to jump if a car rushes past at full speed.

On highways with a posted speed limit of 50 MPH or more, vehicles in a lane directly next to a stationary emergency or police vehicle displaying emergency signals must slow down to a speed of at least 20 miles below the posted speed limit.

When possible, switch to a lane farther away from a stationary emergency or police vehicle displaying emergency signals.

An empty lane between you and the stopped car gives the people beside it room to work.

When possible, vehicles should switch to a lane farther away from the lane that the stationary vehicle is in.
