The other night my daughter(age 17) called me from a remote road stuck in a snow bank which she was not driving. I drove to the site and picked her and 2 friends up. We could not get the car un stuck so we left it there. On the way back to town the police had the road blocked because of a teenage party in the area. The police ordered the kids out of the car and gave them a breathilizer test. My daughter recieved a M.I.P. along with her friends. My question I guess is can the police make my daughter get out of the car and take the test when she is in the custody of her parents? Seems strange to me.
