What is the average insurance settlements on auto accident deaths?

There isn't an average. It depends on how much Bodily Injury Limits the other person has. Most people have policies with $20,000 - $25,000 but can go up from there. That's not to say you'll get it all, it depends on what happened in the accident, and if the person who died contributed at all to it. Either way you only get the max on their policy.
