WW-Different time and place but D_L and I had the experience of getting rear ended hard at a stop sign. That’s about as clear a line of liability as you get (like getting hit in a crosswalk). D_L was much more hurt than I though not a trauma center thing.
We got the medical bills all pushed out as a lien on future settlement. That took a lot off our heads. WW I hope you can get something that goes to the responsible parties insurance first and does not pressure you.
