Rear Ended

I got to use my OnStar for the first time tonight.  I was rear ended on I-25 on the way home.

I was able to stop.  The girl who hit me was able to stop, but a third car hit her into me.  The damage on my car is not terrible, luckily.

I have a little headache; my head hit my head rest.

I am sitting in my car, waiting for the police to take down all of our information so I can get home.

The third car was issued a citation.
