The primary focus of cargo securement is to prevent load shift during transport. Properly securing cargo is essential to ensure that the load remains stable and does not move around while the vehicle is in motion. If the cargo shifts, it can affect the balance of the vehicle, leading to difficulties in handling, potential accidents, and damage to the cargo itself. Proper securement methods, such as using tie-downs, strapping, and other tools, are designed to keep the load in place, minimizing the risks associated with load movement.

Other choices, while they may be considerations in transport, do not directly relate to the primary goal of cargo securement. Minimizing weight can positively impact fuel efficiency, but it does not address the safety aspect of load stability. Hiding cargo from view may be a security measure but is not a primary concern of securement. Lastly, maximizing space might improve efficiency but does not relate to keeping the cargo secured during transit. Therefore, the focus on preventing load shift is critical for safe and responsible hauling.
