What type of mirror is intended to monitor the passengers inside the bus?

The type of mirror intended to monitor the passengers inside the bus is the interior rear view mirror. This mirror is positioned to provide the driver with a clear view of the bus's interior, allowing them to keep an eye on the passengers for safety and operational efficiency.

Unlike exterior mirrors, such as flat, convex, or crossover mirrors, which are designed primarily to help the driver see the areas around and behind the bus for safe maneuvering, the interior rear view mirror serves a specific purpose of monitoring passenger behavior. It helps ensure that passengers are seated safely and not engaging in any actions that could be unsafe during the bus ride.

This distinction is crucial because external mirrors have different functionalities focused on visibility of the roadway and surroundings, rather than monitoring activities within the bus itself, which is essential for maintaining passenger safety.
