What action should you take when approaching a stopped school bus with its lights flashing?

Answer: B — Stop and remain stopped until the lights are turned off

When you approach a stopped school bus that has its lights flashing, the appropriate action is to stop and remain stopped until the lights are turned off. This is crucial for the safety of children who may be getting on or off the bus. The flashing lights indicate that there are children in the vicinity, and they could enter the roadway at any moment. Stopping ensures that you give them the opportunity to cross safely and prevents any potential accidents. Recognizing the importance of this rule is vital for protecting young pedestrians and adhering to traffic laws designed to create a safe environment for schoolchildren.
