Info from Licensor: "I was driving on interstate 25 northbound around 7:50 am when I saw the guy holding onto the rear of the semi-truck. At first, I thought it was faked as I got closer I noticed it was a real guy holding on. Another driver in a truck contacted the driver of the truck as I held back several hundred feet to create distance from the guy. The truck got off the highway and came to a stop, then the guy got down."
