Outside Left and Right Side Crossover Mirrors: These mirrors are mounted on both left and right front corners of the bus. They are used to see the front bumper 'danger zone' area directly in front of the bus that is not visible by direct vision, and to view the 'danger zone' area to the left side and right side of the bus, including the service door and front wheel area.
The mirror presents a view of people and objects that does not accurately reflect their size and distance from the bus. The driver must ensure that these mirrors are properly adjusted.
