This is totally unecessary because New York has a "Captain Obvious" law that requires drivers to move over to the next lane if they can do so safely when passing a cop who is out of his vehicle. The State Troopers have even set up sting operations to entrap violators.
Just the other day I saw an ambulance have to stop and wait for a break in oncoming traffic. I saw the ambulance coming from behind and pulled over. Some idiot decided that was a good time to pass me so he could turn another hundred yards down the road. When he got to his turn, someone had pulled over right at the entrance to the road and the ambulance caught him and traffic from the other direction just kept coming.
