Final answer:
When a school bus is loading or unloading passengers without activated signals, it is not legally required to stop, but caution is advised to ensure safety.
Step-by-step explanation:
The question refers to the rules you must follow when approaching a school bus that is loading or unloading passengers without its signals on. Normally, traffic laws require that all vehicles stop for a school bus with activated signals. However, if the bus signals are not activated, it is not required by law to stop, though you should proceed with caution. This can be related to the general traffic rule that states you must stop your vehicle at a red traffic light. Both rules prioritize the safety of passengers and pedestrians and are essential for preventing accidents. Traffic signals and school bus signals serve as important controls to manage traffic flow and ensure safe road crossings.
