It used to be drivers were supposed to do that to make sure no one was in the trailer. Now streeters are required to go inside and visually check before they even back under the trailer. Shifters are still recommended to bang on the trailer before they pull.
shifters in our yard need to be extra careful...there shouldnt be anybody in the trailers but there might be somebody peeing behind it
