You need to look at Texas Law. And under Texas law the cop was wrong. Number one she was illegally stopped because she pulled away to allow the emergency vehicle to pass. No turn signal required. It was an illegal stop therefore any order he gave her was an unlawful order.What rule says one cannot smoke in one's own vehicle?
When a cop wants you out of the car he doesn't need a lighted cigarette flicked into his face.
Post the law or I call BS.
