Do I have any rights as a co-signer?

 A co-signer on a loan may be either a co-owner or a guarantor for the primary owner or borrower. My guess is that the title to the vehicle was put in both names: your friend's and yours. That is why the insurance company was able to have your license suspended for the wreck.   If you can show that you never operated the vehicle or did not otherwise receive any personal benefit from this arrangement, you may be able to convince the court that your role in this endeavor was as a guarantor.  That would permit you to sue the co-owner for the money you were forced to pay on his behalf.  The legal theory is that, generally speaking, if a guarantor has to pay money on account of the conduct of his principal, the guarantor has a right to be indemnified, that is to say, to be made whole by the other person.   A lawyer experienced in civil litigation should be able to assist you with your case.  While there are some lawyers who might be willing to take your case on a contingency fee basis (taking a percentage of your recover as a fee), you should be prepared to retain (pay upfront or as the case goes along) any lawyer you ask to assist you. The reason for that is that a person who fails to maintain auto liability insurance is likely to be financially unable to pay you the money you were required to pay out.  I hope this helps.
