What type of extrication method is used to stabilize a vehicle that is upside down or lying on its side?

• A. A-Frame
• B. Buttress tension system
• C. Cribbing
• D. Hydraulic stabilizers

Answer: (B)

Stabilizing an overturned or side-lying vehicle relies on bracing the vehicle so it cannot shift during the rescue. A buttress tension system does this by placing sturdy buttress posts against the vehicle and running tensioned lines or straps to anchors on the ground. The resulting tension pushes and holds the vehicle in its current orientation, distributing the forces through the posts and anchors so the vehicle won’t roll, tilt, or drop while rescuers work. This approach is particularly effective when the vehicle isn’t resting on a stable base and doors or roof might move as operations begin, because it provides a controlled, rigid restraint that keeps the patient and rescuers safe. Other methods exist, but they don’t offer the same targeted restraint for a vehicle on its side or upside down. An A-frame focuses on different stabilization configurations and may be less effective for directly resisting tipping of a side-lying vehicle. Cribbing creates supportive blocks but doesn’t actively restrain movement, and hydraulic stabilizers can help with alignment and lift but may not deliver the same robust side-to-side stabilization in a flipped position.
