Where should blocking be used to prevent cargo from sliding?

Answer: C — In front, back, and/or sides of the cargo

Blocking is essential in securing cargo to prevent it from shifting during transport. The correct approach involves using blocking in front, back, and/or sides of the cargo to create a solid barrier that holds the load in place. This comprehensive method of securing cargo minimizes the risk of it sliding during transit due to changes in speed, direction, or road conditions. Using blocking only at the back, sides, or underneath without addressing all sections would leave parts of the load unprotected. Cargo can potentially move if only one area is blocked, which could lead to dangerous situations on the road or cause damage to the cargo itself. Therefore, employing blocking in multiple areas around the cargo ensures better stability and safety throughout the journey.
