What must you do when a school bus is picking up or dropping off children?

Answer: B — Stop and wait until the bus signal is turned off

When a school bus is picking up or dropping off children, it is vital to stop and wait until the bus signal is turned off. This is a crucial safety measure designed to protect children who may be crossing the street unexpectedly as they enter or exit the bus. The bus's flashing lights and extended stop sign indicate that children are in the vicinity, and passing without stopping could put them at serious risk of injury. Areas around schools and school buses are filled with young, unpredictable pedestrians, and they might not always be aware of their surroundings. Stopping ensures that you provide a safe environment for children, allowing them to board or disembark from the bus without the fear of oncoming traffic. This rule is enforced by law in many regions, emphasizing the importance of vigilance and caution around school buses for the safety of children.
