Final answer:
Traffic laws may vary, but generally drivers should stop for school buses loading or unloading passengers, even if signals aren't on, to ensure safety and comply with traffic regulations, prioritizing pedestrian safety.
Step-by-step explanation:
The question is related to traffic laws, specifically concerning how to behave when a school bus is loading or unloading passengers without its signals on. It's important to note that traffic laws vary by location, but generally speaking, in the interest of safety, drivers are often required to stop for school buses under these circumstances to ensure the protection of passengers embarking or disembarking. Not stopping could potentially endanger students and violate traffic regulations.
In some regions, a school bus might use a system of signals (like flashing lights and stop signs) to indicate that it is loading or unloading passengers. If these signals are not activated, the specific local traffic laws would dictate whether you must stop. Nevertheless, as a rule of caution and care for pedestrian safety, it is usually advisable to stop or at least proceed with extreme caution around school buses handling passengers.
