Wheel chocks are wedge-shaped devices used to prevent vehicles from rolling when parked. They are typically made from durable materials like rubber or plastic and are placed against the wheels of a vehicle to provide stability. Wheel chocks are essential for safety, especially on slopes or uneven surfaces. These devices are commonly used in various settings, including construction sites, airports, and garages. By securing vehicles in place, wheel chocks help prevent accidents and injuries caused by unintended movement. Proper use of wheel chocks is crucial for ensuring the safety of both operators and bystanders.
