The statement 'Secure the drive wheels with chocks' is true.

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

Answer: (A)

Wheel chocks are used to prevent a vehicle from rolling when it’s parked or being serviced. The safest practice is to immobilize every wheel that could move, not just the drive wheels. If you only chock the drive wheels, the other wheels could still roll if brakes fail or if the vehicle shifts on an incline. So the idea of chocking only the drive wheels doesn’t provide full immobilization, which is why that statement isn’t correct. In practice, you chock the wheels on both sides of the vehicle (often front and rear) and use the parking brake as well to ensure complete security.
