When are amber warning lights used on a school bus?

Amber warning lights on a school bus are used upon approaching the bus stop to alert other drivers that the bus is getting ready to pick up or drop off students. This signaling is crucial for ensuring the safety of children getting on or off the bus, as it serves as a warning to motorists that they should prepare to stop. The activation of the amber lights indicates that the bus is approaching a stop, prompting drivers to pay closer attention and reduce their speed in anticipation of the bus coming to a halt.

This practice is part of the overall safety protocol aimed at protecting students, as it creates a safer environment around the bus during those critical moments when children may be moving to or from the bus.
