What should a driver do if they see a school bus with its stop sign extended?

Answer: B — Come to a complete stop

When a driver sees a school bus with its stop sign extended, the appropriate action is to come to a complete stop. This is crucial for the safety of children who may be getting on or off the bus. The law is designed to protect students, as they are often in situations where they may unexpectedly dart across the road to reach the bus or their homes. Approaching a stopped school bus with its extended stop sign indicates that students are present and that they must be given the right of way. Stopping ensures that the driver has sufficient time to react to any potential hazards, thus ensuring a safer environment for children. Laws pertaining to stopping for school buses vary by state, but the general principle remains that drivers must stop unless they are on the opposite side of a divided highway. By adhering to this rule, drivers contribute to maintaining a safe community and prevent tragic accidents involving school children.
