After I stopped the car, I went to the van to see if they were okay. Thankfully, the driver and her three daughters were all unhurt. No injuries except for burns and "road rash" on my arms from the airbag. One of the paramedics told me that the airbag frequently causes severe injury in relatively "minor" accidents. This didn't seem all that minor to me, but I guess any accident that everyone walks away from is relatively minor.
The other driver kept apologizing and saying she didn't see me. I could tell she felt really bad about the wreck. I told her that as long as everyone was okay, we had nothing to worry about. Her husband was following her on his Harley. When I discovered that fact, I nearly had an emotional breakdown thinking about what might have happened had I hit the motorcycle rather than the huge van. The lady told me that she had been praying that her husband would be okay on the bike as they returned home to a small town about 100 miles away. Scary stuff.
The police officer wrote the other driver two tickets for failure to yield right of way and for driving without insurance. She repeatedly apologized, and I told her everything was going to be alright. As I left after the wrecker took my vehicle, she apologized again and told me she would pray that I wouldn't be in pain from my (very minor) injuries. I am so thankful to God that the no one was injured. My car is probably totalled, but we are all thankful to be uninjured.
