What if a passenger is killed in your car accident?

It depends. If you are killed, you don't have to deal with anything. But if you survive, you'll probably be asked how you were driving (i.e. drunk driving). then you'll pay a HUGE fine. If it was an accident, then you'll probably be graced, and insurance will cover you. You'll need to have a good explanation, though, for why you had your car accident.
