text: what is the law regarding unmarked police cars pulling you over?there has been a resurgence in impersonation.?   this it what you do when the lights on the unmarked come on step on the gas until you get to 100 and if marked cars start appearing out of no where with lights and siren and they are following you that might indicate the unmarked vehicle is really the police. just kidding lol  i agree with others about stopping where it is safe and call and let them know of what you are doing. also if you see another cruiser beside the one trying to pull you over then pull over then.
