When securing cargo, which condition must all types of cargo meet?

All types of cargo must be fully contained or immobilized by adequate structures to ensure safety during transport. This requirement is critical as it prevents movement that could result in damage to the cargo or the vehicle itself while in transit. Immobilization keeps the cargo in place, minimizing the risk of shifting due to acceleration, braking, or turns, which is crucial for maintaining control and ensuring the safety of the transport operation.

This principle applies to a variety of cargo types, including those that may be loose, large, or inherently unstable if not properly secured. Adequate structures or methods of containment may include straps, nets, walls, or containers specifically designed for transporting the type of cargo in question, ensuring that it remains stable and secure throughout the journey.
