Vehicles on their wheels are best stabilized by using:

• A. Wedges
• B. Cribbing or chocks in front and back of the wheels
• C. High pressure air bags
• D. Step blocks

Answer: (B)

Stability for a vehicle that’s still on its wheels comes from preventing any rolling or shifting. Placing cribbing or wheel chocks in front of and behind each wheel creates solid contact with the ground and the tire, which locks the vehicle in place and distributes the load so it can’t move in either direction. This provides a reliable, simple restraint that protects both the rescuers and the patient during operations. Wedges aren’t as secure because they can shift or slip as the vehicle weight or ground conditions change. High‑pressure airbags are mainly for lifting or supporting loads, not for locking wheels, and they can introduce instability if used as the primary restraint. Step blocks don’t offer the same continuous restraint as cribbing or chocks and can shift under load. So, the best way to keep a vehicle stabilized on its wheels is to use cribbing or wheel chocks placed in front of and behind the wheels.
