Under what circumstances may drivers pass vehicles that are stopped to yield to pedestrians?

Answer: C — None, drivers cannot pass

Drivers cannot pass vehicles that are stopped to yield to pedestrians because it poses a significant safety risk. When a vehicle is stopped, it indicates that a pedestrian is in or approaching the crosswalk. Passing such a vehicle can result in serious accidents, as pedestrians may not be visible to the passing driver and may be in the process of crossing the road. Protecting pedestrians is a critical aspect of driver responsibility, and the law is designed to ensure their safety by preventing any passing in these situations, regardless of other conditions, such as signaling, distance of pedestrians, or the presence of other vehicles. This emphasis on pedestrian safety is vital in promoting responsible driving behavior.
