Pull to the Right! Wisconsin state law says that you must yield the right-of-way to police vehicles, fire apparatus, ambulances or other emergency vehicles using a siren, air horn or a red or blue flashing light. Pull over to the right edge of the road or as near to the right as possible and stop when you see or hear an emergency vehicle approaching from any direction. Follow any instructions given over the emergency vehicle’s loudspeaker. If you are in an intersection, drive through the intersection before you pull over. If the emergency vehicle using lights or siren is on the other side of a divided highway, you do not need to pull over and stop. You must not pass an emergency vehicle that is about to back into, or is backing into, the driveway entrance of a fire and/or EMS station. It is illegal to pass or follow within 500 feet of a moving emergency vehicle with its' red or blue lights on and siren operating. This includes while driving on freeways or other limited access highways.
When approaching law enforcement and other emergency vehicles, tow trucks, road machinery or highway construction or maintenance vehicles (that are stopped on or near a highway and are using flashing emergency lights), you must move into a lane not nearest the stopped vehicle and travel in that lane until you have gone by the stopped vehicle(s). If it is unsafe to move into another lane, slow down until you have passed the stopped vehicle(s).
