When you see an emergency responder or tow truck operator with their lights flashing on the side of the road, it is your responsibility to slow down and move over.
When Police, Fire or tow truck operators are assisting a stranded vehicle or accident, it’s the law to slow down 200 feet before and after the emergency zone. And, if safe and possible, it is your responsibility to move over a lane and allow extra room for the emergency responders. An emergency zone is defined as a zone with vehicles with 360 degrees of flashing lights. So, when you see a tow operator or another emergency vehicle, please slow down and move over.
