What is the primary function of front-end header boards?

The primary function of front-end header boards is to block the forward movement of cargo. These boards are installed at the front of a trailer, particularly in flatbed configurations, to prevent items from shifting forward during transport. This safety feature is crucial to help maintain the stability of the load and prevent potential accidents that could occur if cargo shifts unexpectedly while the vehicle is in motion. The use of header boards is an important part of ensuring proper cargo securement in compliance with safety regulations.

While enhancing vehicle aerodynamics and supporting the weight of the cargo are important considerations, they are not the main purpose of header boards. Fuel efficiency is also an essential aspect of vehicle operation but does not pertain specifically to the function of header boards in maintaining cargo placement and safety.
