Final answer:
Vehicles traveling in the opposite direction of a stopped school bus on a divided highway with a median or barrier are generally not required to stop, but should always drive with care.
Step-by-step explanation:
When you encounter a school bus that has stopped to load or unload children on a divided highway separated by a median or barrier, the rules for vehicles traveling in the opposite direction depend on traffic laws which often vary by jurisdiction. However, generally, these vehicles are not required to stop. This is because the physical barrier or median provides a clear separation of traffic, indicating that the school bus's stop does not impact the opposing lanes of traffic.
Despite not being required to stop, drivers must remain vigilant and drive with care near stopped school buses, as children may be in the vicinity. Additionally, rules can differ in other situations where there is no median or barrier, where in many cases, all directions of traffic must come to a stop.
