Where is cargo blocking typically used?

• A. At the top of the load only
• B. Front, sides, and back of cargo, usually at the floor
• C. Only on the rear of the load
• D. On the sides of the container only

Answer: (B)

Blocking is used to stop cargo from shifting during transit by bracing it on all sides against the trailer and floor. It should surround the load—front, sides, and back—so motion in any direction is absorbed and the load stays tight. Placing blocking at the floor is typical because the floor provides a strong anchor and allows the blocking to press the load firmly against the walls for maximum stability. This reduces the risk of damage to the cargo, the trailer, and anyone nearby if the vehicle stops suddenly. If blocking were used only on one surface, like the top or a single side, other directions could still move, which is why the load needs restraints around it at floor level.
