Final answer:
The driver should slow down and stop if necessary when a tram stops and pedestrians are waiting to cross, prioritizing their safety.
Step-by-step explanation:
When a tram stops ahead, and pedestrians are waiting to cross, the appropriate action for the driver is to slow down and stop if necessary. This ensures the safety of pedestrians who may be crossing the street at an intersection, especially in a school environment where student pedestrians are common. A traffic signal at such intersections aids in managing vehicle speeds and helps to regulate the safe crossing of pedestrians. The appropriate action for the driver when a tram stops ahead and pedestrians get off, waiting to cross, is to slow down and stop if necessary. This allows the pedestrians time to cross the road safely without any risk of collision. It is important for drivers to prioritize pedestrian safety and show caution in such situations.
