What is the primary purpose of cargo covers?

Answer: B — To protect people from spilled cargo

The primary purpose of cargo covers is to protect people from spilled cargo. When transporting goods, especially loose or unsecured items, there's a risk that they can shift or fall out of the vehicle. A cargo cover acts as a barrier, ensuring that the contents of the load stay secure and do not pose a hazard to other road users or pedestrians. This is particularly important for maintaining safety on the road and preventing objects from striking vehicles or individuals. Additionally, while cargo covers may incidentally contribute to improvements in aerodynamics or fuel efficiency, these are not their main functions. The primary focus remains on safety and protection from hazards associated with loose cargo. Meeting weight requirements is also unrelated to the purpose of cargo covers, as weight compliance is typically managed through properly loading the vehicle rather than covering the cargo.
