When are you allowed to pass a school bus that is displaying flashing red lights?

The correct response is that you are allowed to pass a school bus displaying flashing red lights when you are driving in the opposite direction on a multi-lane road. This is because multi-lane roads are typically designed in a manner where traffic is separated by lanes, reducing the risk to children who may be boarding or exiting the bus. The law recognizes that vehicles traveling on different sides of a divided road can safely pass the bus without endangering children, as long as proper caution is taken.

In contrast, passing a school bus with flashing red lights under other circumstances—such as when driving in the same direction, only if there are no children present, or when the bus is moving—is illegal and poses significant safety risks. It's crucial to always adhere to traffic laws regarding school buses to ensure the safety of students.
