Why should you put the starter switch key into your pocket during a pre-trip inspection?

During a pre-trip inspection, placing the starter switch key into your pocket is primarily a safety measure. By keeping the key on your person, it ensures that no one else can start the truck while you are performing your inspection. This is crucial for preventing accidental vehicle movement, which could lead to serious injury or damage. Safety procedures emphasize the importance of securing the vehicle and ensuring that it cannot be started unexpectedly while maintenance is taking place.

Other considerations, such as avoiding loss or having easy access, are relevant, but the key focus during this procedure is the prevention of unauthorized vehicle operation. This practice enhances safety during the inspection process and is a standard operating procedure for professional drivers.
