What is one primary reason for covering cargo during transport?

Covering cargo during transport is essential primarily to protect it from weather elements. Exposure to rain, snow, wind, and sun can lead to significant damage or degradation of the cargo. For instance, rain can cause moisture damage, especially to items like wood or paper products, while ultraviolet rays can affect packaging and perishables. Protecting cargo ensures that it arrives at its destination in the condition it was in when loaded, maintaining quality and safety standards.

While enhancing fuel efficiency, minimizing loading time, and improving visibility may have their merits in specific contexts, the primary concern when it comes to covering cargo is safeguarding it against environmental factors. This understanding ensures that drivers and transporters prioritize adequate protection for their loads during transit.
