How should drivers respond if they encounter a stopped school bus with its lights flashing on the opposite side of the road?

Answer: B — Stop unless there is a physical barrier such as a median

When drivers encounter a stopped school bus with its lights flashing on the opposite side of the road, they are required to stop unless there is a physical barrier, such as a median. This law is in place to ensure the safety of children who may be getting on or off the bus. The flashing lights and extended stop sign indicate that children could potentially be crossing the street, so stopping is crucial to providing them a safe passage. The presence of a physical barrier plays a critical role; if there is a raised median or similar separation that safeguards pedestrians from oncoming traffic, then drivers are not required to stop. This distinction helps streamline traffic for divided roads while still protecting children on busier streets. In the absence of such a barrier, stopping is mandated to allow children to cross safely, reinforcing the importance of vigilance around school buses.
