Option 'Pedestrians crossing with the light' is correct because the Ontario Highway Traffic Act mandates that drivers yield to pedestrians who are crossing the street legally in a crosswalk when the pedestrian signal is active or when the traffic light is green. This law ensures pedestrian safety at intersections and minimizes the risk of accidents. Drivers should be vigilant for pedestrians and proceed with caution, ensuring that the crosswalk is clear before moving. It's a key aspect of safe driving in urban environments in Ontario.
