Which is the primary purpose of wheel chocks?

• A. To measure weight
• B. To lift wheels
• C. To prevent wheel movement
• D. To cut metal

Answer: (C)

The main idea is to keep wheels from rolling by blocking them with a wedge-shaped block. Wheel chocks are placed snugly against the wheel to resist movement, especially when a vehicle is on a slope or is being serviced. They work by using the wedge shape and the wheel’s contact with the tire to create friction that prevents the wheel from turning. They aren’t used to measure weight, nor to lift wheels, and they’re not a cutting tool. For safe use, position the chocks on the downhill side of the wheels (and in front of and behind if you’re on a slope with multiple wheels), keep them firmly against the tire, and remove them only when you’re ready to move the vehicle.
