Mom was rear ended on her trip

Mom was rear ended in West Virginia. She was driving down highway 79 and was hit from behind. She said he hit her from behind then passed her and got off the exit. I just happened to call her because I had not heard from her. I was talking to her when the man came to the car. The police were called and mom was taken to the hospital because she hit her head an she is on blood thinners. She was taken to United Hospital in WV. My sisters are on their way to her now as I type.
