My question involves an injury that occurred in the state of: California
My 16 yr. old unlicensed and therefore uninsured son, was driving the car of a licensed, insured drunk teenager. She gave him the keys. He drive off an enbankment on a one lane dirt road, no injuries but the car is totaled. The car was insured but had no collision due to the fact the the driver had totaled her last car and her parents did not want to pay for it. Is my son responsible for 100% of the the replacement or partial?
