My sister was using my car and got into a car accident while drunk driving. She was obtained at the county jail and received a DUI. What do we tell her's and my auto insurance since we need to file a claim about getting my car fixed?

You need to tell the insurance company exactly what happened or you can be looked at for making fraudulent statements. Ultimately, you need to contact the insurance companies ASAP and speak with the claims department. Good luck, and if you have any questions, don't hesitate to ask.
