Secure the drive wheels with chocks.

• A. False
• B. True
• C. Not Applicable
• D. Not Sure

Answer: (A)

Wheel chocks prevent unwanted movement of a vehicle by blocking the tires that could roll. When you’re working on a vehicle or keeping it steady on a jack or lift, you place chocks against the wheels that remain on the ground so the car can’t move in either direction. If you’re lifting one end of the vehicle, you still chock the wheels on the opposite end to stop the whole vehicle from rolling. Because of this, simply saying to secure the drive wheels with chocks isn’t the standard approach; the safer, correct practice is to chock the wheels that could roll—the ones on the ground or the opposite side of the wheels being raised.
