I rear ended someone who was ticketed for not having a valid license. Am I responsible for paying for the damage on his car? I was also ticketed for the rear-end.
Am I responsible for paying for the damage on his car?
Yes, if you were deemed at fault in the accident. Does the citation you got state that you were at fault in the accident? If so, you are liable for the damage.
If you were at fault in the accident and for the damages, this is an issue between your insurance company and the other drivers' company, and has nothing to do with the fact that the other driver did not have a valid license. (But it could very well be an issue for the other driver and their own insurance company).
