What is the proper response when approaching a school bus with its lights flashing?

Answer: B — Stop until the lights stop flashing

When approaching a school bus with its lights flashing, the appropriate response is to stop until the lights stop flashing. This rule is in place to protect the safety of children who may be getting on or off the bus. The flashing lights indicate that the bus is either loading or unloading passengers, and stopping ensures that children can do so safely without the risk of being struck by a vehicle. This law reinforces the importance of being vigilant in school zones and around buses, as children may not always be aware of their surroundings. Drivers should always be prepared to stop whenever they see a school bus displaying its flashing lights, contributing to a safer environment for students.
