A school bus can have up to a _________-foot tail swing.

The correct answer indicates that a school bus can have up to a three-foot tail swing. This measurement is crucial for understanding how a school bus operates, particularly during maneuvers like turning. The tail swing refers to the area behind the rear axle where the back of the bus can swing out as it navigates a turn.

Knowing that a school bus has a three-foot tail swing helps drivers anticipate the space needed when making turns and how to safely navigate in tight areas, such as school zones or when loading and unloading students. It emphasizes the importance of being aware of surroundings and ensuring that there are no obstacles or students in the immediate vicinity when making these movements. This awareness is not just about safety for the driver but also for the children who are entering or exiting the bus.

Proper knowledge of tail swing allows for better decision-making while driving and can prevent accidents, which is why it is a critical piece of information for anyone preparing for the CDL School Bus Endorsement Test.
