My son was involved in an accident with a serious injury to a fellow student in the back seat (broken neck).
While the accident was not his fault, he was hit in the rear the other driver claimed his brake lights didn't work.
I received a summons to appear in court and faced a $100,000 fine. He was listed on my insurance.
What saved me was the car was titled in his name. During the deposition I swore under oath the car was not a family vehicle, registered in his name and only used by him.
My lawyer said if the vehicle was registered in my name and considered a family vehicle and any blame for the accident was his fault I could have been liable for the $100,000.
The other driver was charged with the accident however, his insurance would not come close to paying the hospital bill so they sued me.
I would contact his other parent's insurance agent for advise and make sure the title is in his name only.
