Final answer:
Drivers should stop and remain stationary when a car is stopped at an intersection to allow a pedestrian to cross. Traffic signals play a significant role in ensuring pedestrian safety and controlling vehicle speed. Real-world scenarios emphasize the need for both adherence to traffic laws and situational assessment for safety.
Step-by-step explanation:
When a car is stopped at an intersection or crosswalk to allow a pedestrian to cross the street, the driver should stop moving and remain stationary until the pedestrian has safely crossed. Ensuring pedestrian safety is critical, and many students and others might have to navigate busy intersections when coming to or leaving campus. The presence of a traffic signal would be beneficial as it would regulate the flow of both vehicular and foot traffic, allowing pedestrians to cross at appropriate times, and making drivers slow down in compliance with the traffic laws.
For example, Jane's act of helping a slow-moving pedestrian at a traffic light emphasizes the need for motorists to be vigilant and patient, as unpredictable situations can arise. Furthermore, considering the safety of a pregnant woman and an urgent scenario where a driver might navigate traffic signals, it underlines the balance needed between strict adherence to rules and assessing situations for the greater good.
