Point being, still best to cover your butt and set the park brake. Most of us don't in our personal vehicles, but best to set it in UPS vehicles.
I've never driven a commercial vehicle. When I was still driving a personal vehicle, I'd set the e-brake
everytime that car was in park. My father was riding in the car with me once when I did that and asked why. I told him about seeing a sedan roll away in a parking lot of a grocery store I worked in. The car rolled right into an SUV when the owner got out of the car. I was first to arrive on the scene (right after the driver of the sedan) and sure enough, the car was supposedly in park. Moral of the story: I
always set my e-brake! Excessive? Maybe. Additional wear and tear on the brakes? Probably. Never having the embarassment (or an insurance claim for carelessness) for a roll-away? Priceless.
They were suspending or firing guys for not using seatbelts when I retired.
I might take heat for this but I think they
should be fired if they are NOT using their seatbelts. I was in two collisions as a driver--one would have been fatal if I'd been driving a smaller car when being hit by something like an SUV (long story). The seatbelt saved my life in a collision as a kid when my mother rear-ended a Suburban at 30. I'm a very big advocate of seatbelts. Right after I started driving, I threw a kid out of my car that refused to buckle up. I was almost deafened by yelling when my father found out I'd thrown the kid out. He calmed down when I told him my side of the story and offered my license if he didn't agree with my actions--then or in the future--if it happened again. Never another problem with seatbelts....-Rocky
