What must be checked about the catwalk during the vehicle inspection?

During a pre-trip vehicle inspection, checking the catwalk is crucial for ensuring safety and functionality. The catwalk must be clear of any objects and securely bolted to the tractor frame. This is vital because any debris on the catwalk can create a slip hazard for the driver or anyone accessing the trailer, while a catwalk that is not securely attached could fail during operation, leading to severe accidents or injuries.

A securely bolted catwalk ensures that it can reliably bear the weight of a person accessing the trailer without shifting or coming loose. This check is part of ensuring that all components related to the coupling system and accessing the trailer are safe and functioning properly, facilitating safer operations on the road.
