When should a driver especially be on the lookout for pedestrians with disabilities?

The correct choice emphasizes the importance of being vigilant for pedestrians with disabilities at bus stops, intersections, and business areas because these are locations where people frequently interact with vehicles.

At bus stops, drivers should be aware that individuals with disabilities may require additional time to board or disembark from buses and may not move as quickly as other pedestrians. Intersections are critical spots where pedestrians, including those with disabilities, cross roads, making it essential for drivers to be especially cautious and patient. In business areas, the presence of pedestrians is typically higher due to the nature of these locations. Therefore, increased awareness in these specific environments helps ensure the safety of all road users, particularly those who may need extra assistance.

Other options, while important in certain contexts, do not specifically highlight the environments where pedestrians with disabilities might be most vulnerable or present.
