On [XXX], I was operating (bobtail) truck number [XXX] and needed to complete some tasks outside the truck. I set the parking brakes by pulling the yellow valve out. The truck didn’t make the usual loud noise we hear every time we set the brakes. After a couple of minutes of reviewing the documentation I was supposed to drop off at that location, I stepped out of the truck with the key in my pocket and walked away from it. When I was about 100 feet away from the truck, I saw it rolling down on my right side. I went to recover the truck, and the first thing I checked was the yellow valves. Both valves were pulled out. I put the key in the ignition and started the truck. I pressed the yellow valve in, but there was no noise, and the feeling was a bit different. I did press the red valve in and heard that air noise. I pulled back out again and reversed the truck back to where I originally parked it. I notified safety and also requested by text to my supervisor, Shania, that the valves should be checked before any other driver would drive it. So far I haven’t been told what caused the roll away. No one got hurt, no citation, but the area where this incident happened is the entrance and exit of every employee in that building. I was let go from work on July 21,2026. Today is August 4, 2026 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
