What is the function of wheel chocks during a pre-trip inspection?

The function of wheel chocks during a pre-trip inspection is primarily to prevent the vehicle from rolling while parked. When a vehicle is stationary, especially on an incline, there is a risk that it could move unexpectedly. By placing wheel chocks against the tires, you create a physical barrier that helps to keep the vehicle securely in place. This is particularly important when the vehicle will be inspected or serviced, as ensuring that it remains stationary is crucial for the safety of the personnel involved in the inspection.

While wheel chocks are beneficial for various aspects of vehicle stability, their principal role during a pre-trip inspection is to enhance safety by immobilizing the vehicle, thus allowing for a safe evaluation of its exterior and any necessary maintenance checks without the danger of it moving. This precautionary measure is a key part of ensuring that both the driver and the vehicle's condition are properly assessed before road operation.
