For what reason should you keep the starter key in your pocket during a pre-trip inspection?

Keeping the starter key in your pocket during a pre-trip inspection is primarily for safety reasons. When conducting a pre-trip inspection, the vehicle should not be in operation, and having the key in your pocket ensures that you cannot accidentally start the engine while checking the various components of the vehicle. This practice minimizes the risk of injury both to yourself and others who may be nearby during the inspection process. Proper safety protocols involve ensuring that the vehicle is not in gear and cannot be inadvertently started; having the key in your pocket reinforces this precaution.

While the other options touch on relevant points such as vehicle theft and reminders related to the ignition, the core focus here is maintaining a safe environment during the inspection process.
