When the interior mirror is adjusted properly in a bus, what should you see?

When the interior mirror is adjusted properly in a bus, it should provide a clear view of the widest part of the interior of the bus and the right side windows. This positioning allows the driver to effectively monitor passenger activities, ensure safety, and maintain awareness of the bus's interior environment.

By having a clear line of sight to the wider areas within the bus, the driver can gauge the presence of standing passengers, monitor for safety concerns, and maintain overall awareness of the bus's interior dynamics. This is especially important for preventing accidents and ensuring the safety of passengers while the bus is in motion.

Other choices do not provide the best perspective for effective bus operation. For instance, viewing the front dashboard and controls is important but does not aid in monitoring the interior. The driver's seat and backrest being visible does not enhance overall situational awareness. The left side mirror and rearview camera focus more on the external environment rather than providing a comprehensive view of passengers and their activities inside the bus.
