Those guys are replacing the rear door frame of the tractor trailer. Somewhere along the line the original frame had a tab broken off so we ran it for a while with the red one until I could buy a replacement. Tyler wasn't content to just swap them though, as I found this set up.
This guy is on his way to the repair shop. I happen to like how his hands are "flailing" at the wheel as he knocks over the traffic light!
