What should be done first if a suspicious package is found on the bus?

Pulling the bus over is the most appropriate first action if a suspicious package is found. This ensures the safety of all passengers and allows the bus operator to assess the situation without putting anyone at further risk. Stopping the bus enables the operator to create a safe distance between the potential threat and the passengers, controlling the environment and preventing panic.

It's crucial to prioritize safety and ensure that all passengers remain calm. Once the bus is safely parked, appropriate measures can be taken, such as notifying authorities or notifying dispatch for further instructions on how to handle the situation.

In contrast, checking the package or driving to the nearest station could expose the passengers to potential danger, and calling a friend does not address the immediate safety concerns. Therefore, pulling the bus over is a decisive and responsible first step in managing a suspicious situation onboard.
