I live in Indiana and I was in a Lyft ride share and was in an accident. I had injuries why won't the insurance company give me?
Was in a Lyft ride share accident
You sue the driver. The driver then contacts his insurance company (or doesn't). You have no rights directly against the driver's insurance, only against the driver.
The above is general legal and business analysis. It is not "legal advice" but analysis, and different lawyers may analyse this matter differently, especially if there are additional facts...
