According to the story, this was a rear-end collision. Watch your following distance, and pay attention when coming to a stop-light.
Thoughts and prayers to the family.
The 1st thing I thought was driver error, but, I have to catch myself, could have been a number of other things, heart attack or other health issue, run away motor or other mechanical issue.
I had been researching the run away motor the last couple days before seeing this accident. After reading a couple runaways online I had one of those semi night mares where it happened to me in a dream. Not sure how I would react initially. I did explain to my wife if it happens to throw the truck in neutral since turning off the key would not stop the motor from accelerating out of control. Think if it happened at the most inopportune time, which is the only time it would happen, it would be quite startling.
If anyone can find out who the driver was, please post here, and if any help could be extended toward family.
Be careful out there.
