What must occur after step chocks are placed under the side of the vehicle?

• A. Deflate the tires
• B. Set the parking brake
• C. Check for leaks
• D. Move the vehicle

Answer: (A)

Placing step chocks on the side of the vehicle is a stabilization move to keep it from rolling. Once those chocks are in place, deflating the tires on that side helps the wheel settle cleanly onto cribbing and reduces the tire’s resistance against movement as you continue to stabilize or lift. With less air pressure, the tire won’t push back against the rim or deform as you build support, which makes the overall stabilization safer and more secure. The other actions aren’t the immediate next step in this sequence—parking brakes are normally set earlier to prevent movement, leaks aren’t a direct concern for stabilization, and moving the vehicle would defeat the purpose of stabilizing.
