What should you do when you see a school bus with its stop sign extended?

Answer: B — Stop your vehicle in both directions

When you see a school bus with its stop sign extended, the appropriate action is to stop your vehicle in both directions. This rule is in place to ensure the safety of children boarding or disembarking from the bus. When a school bus is stopped and its stop sign is extended, it is a clear signal that children may be crossing the road, and it is crucial to halt your vehicle to give them a safe passage. Stopping in both directions is especially important on undivided roads, where vehicles on both sides of the bus must obey this safety measure. This helps create a safe environment for children, who may not always be aware of oncoming traffic. Other actions, such as continuing to drive, suggest disregard for the safety protocols established around school buses. Additionally, merely slowing down or honking could be distracting or alarming to children, who may be focused on crossing the street safely. Therefore, stopping is the only responsible response when you encounter this situation.
