What is required from drivers when they see a stopped school bus with flashing lights?

When drivers encounter a stopped school bus displaying flashing lights, they are legally required to slow down and prepare to stop. This regulation is in place to ensure the safety of children who may be boarding or disembarking from the bus. The flashing lights serve as a critical indicator that children could be present in the vicinity, requiring all vehicles to exercise caution and be ready to halt completely when approaching the bus from either direction.

Slowing down is key because it not only provides drivers with the necessary time to react but also helps to safeguard the children's safety as they enter or exit the bus. The law emphasizes the importance of this precaution, reflecting the higher risk associated with children in these situations, since they may not always be visible to drivers or may suddenly enter the roadway.

In this context, the other choices do not align with safety protocols. Continuing to drive at the same speed poses significant dangers; signaling the driver is unnecessary and does not contribute to safety measures; and passing the bus carefully can lead to severe accidents, as children may be crossing the street at unpredictable times. Following the requirement to slow down is essential for safeguarding lives.
