Wheel chocks are commonly made from which materials?

• A. Wood, plastic, or metal
• B. Glass
• C. Ceramic
• D. Fabric

Answer: (A)

Wheel chocks need to be solid, durable barriers that can withstand the weight of a vehicle and resist weathering, while still being practical to handle and position. Wood, plastic, or metal blocks provide the necessary rigidity and strength, so they won’t crumble or deform under wheel pressure and can be shaped to wedge securely against the tire and surface. These materials are also widely available, cost-effective, and can be manufactured in various sizes and finishes to suit different vehicles. In contrast, glass and ceramic are brittle and prone to breaking under load, which creates safety hazards. Fabric is not rigid enough to hold a wheel in place and would slip or deform, making it ineffective as a chock.
