Blocking refers specifically to the use of materials, such as wood, to stabilize and prevent cargo from shifting during transport. It helps ensure that the load remains in a fixed position, thereby enhancing safety and preventing damage to the cargo or the vehicle. Proper blocking is crucial for maintaining balance and stability, especially when dealing with irregularly shaped loads or when transporting cargo over various road conditions.

Utilizing chains, padding, or strapping are all methods involved in securing cargo but do not fit the specific definition of blocking. Chains are primarily used for additional security, while padding protects against damage. Strapping holds the load in place but does not involve the physical stabilization provided by blocking materials. Thus, the focus on wood or similar materials explicitly identifies the concept of blocking in load securement practices.
