“…every owner of a motor vehicle registered in this state…shall, at all times, maintain in force with respect to such vehicle security for the payment of loss resulting from the liability imposed by law for bodily injury, death and property damage sustained by any person arising out of the ownership, maintenance, operation, or use of the vehicle…”
