I'm so sorry. I wonder if your mom realizes that she is putting herself in such a bad situation. If they're stopped by the police, mom is going to be charged for constructive possession of cds, cds in a motor vehicle, and anything else they can think up. It will cost her a nice chunk of change for an attorney, she may end up having to plead to something lesser, and then is going to have to deal with fines and probation, possible loss of license. Maybe if you explain that to her, she will have a moment of clarity?
