Auto hitting my grandson on his bicycle
My grandson was riding his bicycle in our mobile home park and he was on the wrong side of the road. As he turned the corner a car hit him. He was not injured only shaken up. The owner of the car is now telling me that I need to repair her car. Am I legally responsible to pay for the damages? She refuses to turn it into her auto insurance, and claims my grandson was at fault. What do I do?
