What should be the initial focus when inspecting a large commercial truck or van?

The initial focus when inspecting a large commercial truck or van should indeed be on the driver interview and the appropriate vehicle documents. This is crucial because it sets the foundation for the entire inspection process. The driver interview allows the inspector to gather valuable information regarding the vehicle's usage, maintenance history, and any recent issues that may have arisen.

Additionally, reviewing the appropriate vehicle documents—such as registration, insurance, and permits—ensures that the vehicle is legally compliant and has been maintained according to regulatory standards. These documents also serve as a point of verification about the vehicle’s history and can help to identify any discrepancies that might warrant further investigation.

Focusing on these aspects at the outset provides essential context for understanding the compliance and safety of the vehicle, which is important for ensuring road safety and adherence to regulations.
