That was my thought. Drivers do it all the time here
Same here. I've had some of my guys either back into the fence and swear they did their walk around, then don't have an answer as to how they checked the lights on the trailer. Or not set the brakes and roll into the culvert along the opposite fence.
Once had a guy swear someone broke the window in his truck and steal his radio .. come to find out he took the radio home the previous friday ... and no one broke the window, he just didn't roll it up
...the list goes on
