In what situation should the amber warning lights be activated?

Activating the amber warning lights is essential for alerting other road users that the school bus is preparing to pick up students. This alert signals drivers to slow down and be cautious as children may be crossing the street or nearing the bus during the loading process. The use of amber lights serves as a warning before the bus comes to a complete stop, giving drivers advance notice to expect potential hazards.

In contrast, while approaching a stop is part of the bus's operational procedures, amber lights specifically indicate the preparation for loading or unloading. Zero visibility conditions may require additional caution, but it does not specifically dictate the activation of amber lights. Similarly, idling does not necessitate the use of warning lights since the primary goal is to signal impending passenger boarding rather than convey that the bus is stationary. Understanding the function of amber warning lights helps ensure safety during student pick-up and drop-off.
