In a structurally compromised vehicle, which technique reduces movement?

• A. Drive the vehicle on blocks
• B. Push on the vehicle to test stability
• C. Use cribbing and struts anchored to solid ground to limit shifts
• D. Ignore the instability

Answer: (C)

Stabilizing a structurally compromised vehicle to prevent movement is essential for safe extrication. Using cribbing and struts anchored to solid ground creates a rigid, controlled stabilization system that resists both vertical and horizontal shifts. Cribbing provides a stable platform at critical contact points, distributing the vehicle’s weight and absorbing small adjustments, while struts can be extended, locked, and tuned to hold the vehicle firmly in place. Anchoring to solid ground ensures the stabilization remains solid even if the vehicle deforms or the surrounding surface shifts, rather than relying on the vehicle itself or on a temporary surface that could move. Driving the vehicle on blocks can be unpredictable because the blocks may shift, settle, or fail under load, which reintroduces movement. Pushing on the vehicle to test stability introduces a risk of sudden movement and further damage. Ignoring the instability is unsafe because any further movement can endanger victims and rescuers. In short, cribbing and struts anchored to solid ground provide a dependable, controllable way to keep the vehicle from moving during extrication.
