What action should you take when you see a school bus with its red lights flashing?

Answer: B — Stop your vehicle until the lights stop flashing

When you see a school bus with its red lights flashing, you must stop your vehicle until the lights stop flashing. This rule is crucial for the safety of children who may be boarding or disembarking from the bus. The red lights serve as a signal that children may be crossing the street, and stopping as required ensures that you do not endanger their safety. The law mandates that drivers in both directions must stop when a school bus is displaying its flashing red lights, which is an indication that the bus has stopped to load or unload children. This law is in place to create a safe environment for children as they interact with the school bus. Once the lights stop flashing, and it is clear to proceed, you can safely continue your travel.
