I am moving to FL from PA and plan to convert my drivers license. The problem is I will be borrowing my parents vehicle. The vehicle is titled and registered to them in PA. (I am listed as a driver on their insurance) I obviously cannot register a vehicle that I do not own and they cannot register a vehicle in a state that they do not live. What do we need to do? Would a notarized letter suffice if I was pulled over and questioned for having a FL license but a vehicle with PA tags and plates?
