Why should you keep the starter switch key in your pocket during the pre-trip inspection?

Keeping the starter switch key in your pocket during the pre-trip inspection is primarily about safety—specifically, preventing unauthorized individuals from starting the vehicle. When conducting a pre-trip inspection, it's important to ensure that the vehicle remains stationary and secure to avoid any potential accidents or injuries. If someone were to mistakenly or intentionally start the truck while you are performing your checks, it could lead to serious consequences, including injury to yourself or others.

This practice is part of a broader safety protocol that aims to keep drivers and equipment safe while servicing or inspecting vehicles. By keeping control of the key, you reduce the risk of accidents caused by an unattended vehicle starting unexpectedly. Security of the vehicle is also enhanced, ensuring that only authorized personnel can operate the truck at any given time.

While there are valid reasons for keeping the key secure to prevent loss or electrical issues, the most critical element during an inspection is the prevention of unintentional engine startups, thus ensuring the safety of the inspection process.
