Which action is required when approaching a school bus with its red lights flashing?

When approaching a school bus that has its red lights flashing, it is essential to stop until the lights cease flashing. This requirement is in place to ensure the safety of children who may be boarding or exiting the bus. The flashing red lights serve as a clear signal that the bus is stopped to pick up or drop off passengers, and it is crucial for drivers to respect this warning.

Stopping allows children to cross the street safely without the concern of oncoming traffic, as many children may be unpredictable and not always aware of their surroundings. The law mandates this action to create a safe environment around school buses, reflecting a broader commitment to child safety in transit.

Other actions, such as slowing down and proceeding with caution or driving past the bus without stopping, do not prioritize safety and could endanger children. Additionally, honking to alert children is not only unnecessary but could also contribute to confusion or panic among young pedestrians.
