How far behind the rear bumper may the danger zone of a school bus extend?

The correct answer indicates that the danger zone of a school bus can extend 400 feet behind the rear bumper. This distance is critical for ensuring the safety of children as they enter and exit the bus. The danger zone represents an area where children may be at risk of being unseen by the driver, especially when the bus is in motion or when the driver is focused on the road ahead.

Understanding the extent of this danger zone helps bus drivers maintain vigilant awareness while operating a school bus, particularly in areas where children may be boarding or alighting. This awareness is essential for preventing accidents, as children may not always be cautious or visible in these areas. Hence, recognizing how far back the danger zone extends reinforces the importance of careful driving practices and proper monitoring protocols in school transportation.
