Move Over, Slow Down



 The Move Over, Slow Down law can mean the difference between life and death; the only way to prevent tragedies from occurring on the side of the road is by giving emergency personnel, highway workers and the public, space.


It only takes a split second of inattention to destroy the lives of so many people; give the public and those who do business along the side of California’s roads a safer place to work: move over, slow down.

The law requires motorists to move over to a lane not immediately adjacent to a stationary vehicle(s) displaying either the flashing emergency lights, or amber warning lights, or slow down if a lane change cannot be safely made.


The Freeway: Stationary Vehicles Displaying Emergency or Warning Lights (aka – Move Over, Slow Down) law went into effect in California on January 1, 2007. It was amended in 2009 to include Department of Transportation (Caltrans) vehicles that are displaying flashing amber warning lights.


This law requires a motorist who is operating a vehicle on a freeway and approaching in a lane immediately adjacent to a stationary authorized emergency vehicle that is displaying emergency lights, a stationary tow truck that is displaying flashing amber warning lights, or a stationary marked Caltrans vehicle that is displaying flashing amber lights to change lanes safely or, if unsafe or impracticable, slow to a reasonable and prudent speed that is safe for existing conditions.
