CDL School Bus Endorsement Practice Exam

Properly adjusted mirrors are crucial for a school bus driver, but the assertion that you should be able to see the front tires touching the ground is misleading. Instead, the primary focus should be on ensuring that the mirrors provide a clear view of the area around the bus, particularly the blind spots, and the position of other vehicles near you. The correct approach to mirror adjustment involves maximizing visibility to anticipate hazards, particularly when making maneuvers or during stops. Good visibility includes the sides of the bus and the area directly behind it, which helps in gauging the distance from other vehicles and obstacles. While some operators might set mirrors to see the front tires in an effort to gauge clearance or alignment, this is not a standard part of safe mirror adjustment for operational driving. The focus should instead be on an overall comprehensive view around the vehicle, ensuring safety rather than fixation on the front tires themselves.
