Which stabilizing tool is designed to stabilize vehicles resting on their sides or roofs?

• A. Hydraulic ram
• B. Pneumatic jack
• C. Tensioned buttress system
• D. Chain winch system

Answer: (C)

When a vehicle is resting on its side or roof, you need a stabilizing setup that creates a rigid restraint to prevent tipping or shifting. A tensioned buttress system does this by placing stabilizing frames (buttresses) against the vehicle and anchoring them to solid surfaces. A tensioning element—like a strap or cable with a turnbuckle—then pulls tight to hold the vehicle in its current orientation, resisting movement in multiple directions while extrication work is performed. This provides a stable, controlled restraint that other tools—such as hydraulic rams or pneumatic jacks (which lift or pry)—and chain winch systems—do not specifically offer for side/roof stabilization.
