What does the yellow flashing light on a school bus indicate?

The yellow flashing light on a school bus serves as a warning to other drivers that the bus is preparing to stop in order to let children on or off. This means that drivers should slow down and be alert for the possibility of students entering or exiting the bus. The yellow light is an important safety feature designed to protect children, as it signals that the bus is making a transition and that caution is necessary. This designation helps ensure that drivers are aware that they need to be prepared to stop, as it indicates that the bus is not yet at a full stop but is nearing that point. This understanding is essential for promoting safety around school buses.
