What is the correct response to a school bus with its stop sign extended?

Answer: B — Stop and remain stopped until the sign is retracted

When a school bus has its stop sign extended, it indicates that children are either boarding or alighting from the bus. The law requires vehicles approaching from either direction to stop completely and remain stopped until the stop sign is retracted and the bus lights cease flashing. This measure is crucial for the safety of the children, who may unexpectedly cross the street. Thus, stopping protects them and ensures that they have a safe environment to enter or exit the bus. Adhering to this rule is essential, not just for compliance with traffic laws, but also for promoting a safe community.
