When a bus has a rear overhang while leaving a curve, what should the driver be cautious of?

The correct choice highlights the importance of awareness regarding the rear overhang of a bus when navigating curves. Buses are larger vehicles with substantial rear overhang, meaning that when turning or maneuvering, the back of the bus can extend into areas that are not immediately visible to the driver. As the bus leaves a curve, it can inadvertently move into lanes or pedestrian spaces that might be occupied by pedestrians or stationary objects, which could lead to collisions.

Being cautious about striking pedestrians or objects near the curve is crucial for safety, as it helps to prevent accidents and protect those who may be in close proximity to the bus. This awareness is especially vital in urban environments where pedestrians are often near the edges of the roadway.

Other choices, while important aspects of driving, do not directly relate to the specific risk associated with a bus's rear overhang during a curve. For instance, while accelerating quickly can indeed pose risks, it’s not uniquely tied to the issue of rear overhang during a curve. Similarly, turning too sharply and driving over the speed limit both involve general driving safety considerations but do not address the specific safety requirement of being mindful of the vehicle's dimensions in relation to surrounding elements while exiting a curve.
