Which tool is used to stabilize a vehicle by distributing weight on the ground?

• A. Chocks
• B. Step blocks
• C. Cribbing
• D. Ratchet straps

Answer: (C)

Cribbing is used to stabilize a vehicle by distributing weight across the ground. By stacking solid blocks in a stable, interlocked pattern, you spread the vehicle’s load over a larger ground area and across multiple contact points. This reduces the risk of ground sinking or shifting and creates a solid base that resists movement during rescue operations.

Chocks mainly stop wheels from rolling but don’t provide a broad, load-distributing base. Step blocks can help with height but aren’t designed to create a stable, weight-distributing platform. Ratchet straps secure components or loads but do not bear or distribute the vehicle’s weight. Using cribbing properly—base layers on firm ground, interlocking stacks, and top contact points aligned with the vehicle—gives a stable, safe foundation for operations.
