Where should emergency exits be located on a school bus?

Answer: B — At both front and rear of the bus

Emergency exits on a school bus are critical for ensuring the safety of passengers in case of an emergency situation. Having emergency exits located at both the front and the rear of the bus maximizes the options available for passengers to evacuate quickly and safely. This design consideration allows for multiple escape routes, which can be crucial in situations where one exit may be blocked or inaccessible. In emergencies, quick evacuation is vital, especially for young passengers who may need guidance in exiting the bus. By having exits at both ends, it reduces bottlenecks and helps facilitate a smoother and faster evacuation process. Other choices lack proper safety standards; for instance, having exits only at the front could limit escape options in emergencies. Relying solely on side exits would also be insufficient, as they may not be accessible in all situations. Lastly, the absence of emergency exits altogether would be highly unsafe, eliminating vital escape routes when needed most.
