What happens when a person with a suspended license is involved in an accident in another person's car and is not at fault?

Actually, they are At Fault, or so it's presumed - if their license is suspended, they shouldn't have been driving, hence, they should not have been there to have been involved in an accident. On top of that, they've voided their insurance policy by driving on a suspended license, so the expenses will likely end up coming out of pocket.
