Why is it important to chock the wheels during a pre-trip inspection?

Chocking the wheels during a pre-trip inspection is crucial for stabilizing the vehicle. When a truck is parked on an incline or even on level ground, there is a risk that it could roll if the brakes fail or if it is improperly secured. By placing chocks, which are wedges made of sturdy materials like wood or rubber, in front of or behind the wheels, you create an additional level of safety that helps to prevent any unintended movement. This is particularly important during loading and unloading operations, where the vehicle may be lifted or shifted, creating conditions that could lead to a loss of control. Ensuring the vehicle is stable protects both the equipment and personnel working around it, thereby enhancing overall safety on the job site.
