I've been told that in Texas in Louisiana that you are required to show you license whenever approached by a policeman. Obviously this is when pulled over by one. HOWEVER. What if I am riding with a friend and he is pulled over and the officer is approaching him. I am not under arrest or approached or pulled over, I am just sitting quietly in the car. Do I need to get into it and show him my license and all that then? Or do I wait until he asks me anything or gets us both out of the car or such?
