What is created using one or more struts and a ratcheting device to apply lateral and upward force to a vehicle to decrease the likelihood of a vehicle tipping over during rescue operations?

• A. Tensioned buttress system
• B. Hydraulic stabilization system
• C. Spreader brace
• D. A-frame shoring

Answer: (A)

Vehicle stabilization during rescue focuses on creating a counteracting moment to keep the car from tipping as you work. A tensioned buttress system does this by placing one or more struts against the vehicle and using a ratchet to tighten them. The tensioned struts push laterally and create an upward component, helping to seat the vehicle more securely and reduce the risk of tipping as extrication proceeds. This mechanical tightening with a ratchet is what distinguishes it from other stabilization methods that rely on hydraulics, spreading braces, or vertical shoring.
