When adjusting crossover/cross view mirrors, what should school bus drivers aim to see?

School bus drivers should aim to see the right and left front tires touching the ground when adjusting crossover/cross view mirrors. This is crucial for ensuring proper visibility around the bus, particularly in relation to the area directly in front of the bus. By being able to see the front tires, drivers are better positioned to monitor the immediate vicinity and have a clear view of any potential hazards or obstacles, including children who may be nearby when the bus is stopping or starting. This focus on the tires helps drivers understand the bus's exact location on the roadway and assess the distance to the curb and other vital areas. The mirrors play a significant role in providing the necessary awareness to ensure the safety of young passengers and pedestrians.
