What is the proper way to adjust mirrors before operating the bus?

The proper way to adjust mirrors before operating the bus is to sit in the driver's seat and adjust the mirrors to ensure a clear view of the surroundings. This method is essential because it allows the driver to position the mirrors in a way that optimally reduces blind spots and enhances visibility of other vehicles and pedestrians. When seated in the driver's position, the operator can accurately gauge the angles needed to ensure safety and awareness while driving.

Adjusting mirrors from the driver's seat helps establish a view that aligns with the operator's line of sight and personal height. This way, the mirrors can be set for maximum effectiveness, which is crucial for safe driving. It also ensures that adjustments are made in a controlled environment before the bus is in motion, minimizing risks.

The other methods present drawbacks that compromise safety and efficiency. For example, adjusting mirrors while driving is not advisable as it distracts the driver and diverts attention away from the road. Standing outside the bus to adjust mirrors is impractical for the same reason; it doesn't provide the necessary perspective and introduces hazards. Additionally, relying on someone else to assist with mirror adjustments can lead to miscommunication or inaccurate placements, which can impact the driver's visibility and safety.
