What is the primary purpose of using mirrors while driving a school bus?

The primary purpose of using mirrors while driving a school bus is to look for obstacles and ensure safety. Mirrors provide critical visibility to the driver, allowing them to monitor their surroundings effectively. This includes checking for other vehicles, pedestrians, and any potential hazards in the bus's blind spots. Since school buses often pick up and drop off children, it becomes even more essential for drivers to be aware of their environment to prevent accidents and ensure the safety of passengers.

In contrast, enhancing fuel efficiency, monitoring passenger behavior, and checking weather conditions are important aspects of driving and operating a bus, but they do not focus specifically on the use of mirrors. The primary goal of utilizing mirrors is focused on maintaining safety and awareness while navigating the roadways.
