What is the primary role of wheel chocks?

The primary role of wheel chocks is to prevent the vehicle from rolling when parked on an incline. When a vehicle is on a slope, gravity can cause it to roll, potentially leading to dangerous situations or accidents. Wheel chocks are placed under the wheels to create a barrier that stops the vehicle from moving. This safety measure is crucial, especially for larger vehicles, such as trucks, as they can carry significant weight and momentum, making them more difficult to control if they were to roll unexpectedly. Proper use of wheel chocks enhances safety by ensuring that vehicles remain stationary when they are parked, particularly in environments like loading docks, where inclines are common.
