True or False: It is acceptable to leave your vehicle without engaging the parking brake when you are only away for a moment.

Answer: B — False

Leaving your vehicle without engaging the parking brake is unsafe and can lead to an unintended movement of the vehicle. Even if you believe you will only be away for a moment, it is crucial to secure the vehicle properly to prevent accidents. Engaging the parking brake provides necessary security against rollaway incidents, which can happen even on flat surfaces due to various factors such as incline or vehicle vibrations. The other options imply scenarios where it might be deemed acceptable, but none of these provide a sound basis for bypassing the safety of using the parking brake. Regardless of the situation, the safety protocols dictate that the parking brake should always be engaged when exiting the vehicle to ensure it remains stationary.
