Any assets owned jointly with a spouse are protected (unless the spouse is also liable-doubtful) After that your auto insurance will cover you up to your limit of liability protection purchased. Then you are exposed. However, if you have no assets you are judgment proof. Good luck, Peter Hart
You can either hire your own lawyer to answer these questions because you did not provide enough facts in your question, (you could probably find an attorney that will provide a free consultation), or better yet, ask these questions of the lawyer that your insurance company will provide for you. I am also available, at no cost, if you would like to contact me.
