When using a vehicle as an anchor, which action should be performed first?

• A. Remove keys
• B. Chock Wheels
• C. Set parking brake
• D. DO NOT use bumper or tow hooks

Answer: (B)

Preventing movement of the vehicle is the priority when using it as an anchor. Placing wheel chocks on the tires creates an immediate, passive barrier that stops rolling in either direction, giving you a stable anchor before you do anything else. With the vehicle firmly immobilized by chocks, you can then proceed to engage the parking brake and manage the scene more safely, knowing the vehicle won’t shift under load. Removing the keys is still a good safety step to prevent accidental starting, but it doesn’t provide the immediate immobilization that chocks do. Avoid using bumper mounts or tow hooks as anchor points because they’re not rated for these loads and can fail, endangering anyone nearby.
