When a vehicle with flashing lights is stopped on or next to a roadway, drivers approaching the vehicle should:

change into a lane not immediately adjacent to the vehicle, or
slow down to a reasonable speed if you’re unable to safely make a lane change.
Move Over – It's the Law
All 50 states have "Move Over" laws to protect law enforcement officers and other first responders stopped on roadways, yet one-third of Americans are not aware of these laws. Violation of the Move Over law results in fines and in some cases jail time.

Remember, next time you see flashing lights on the side of the road or roadside workers, Move Over. It’s the Law.
