Under what condition is a driver not required to stop for a school bus?

A driver is not required to stop for a school bus when traveling on a divided highway that has a median or barrier separating the lanes of traffic. This is because the physical barrier provides a clear separation between the lanes where traffic flows in opposite directions, which helps to ensure the safety of both the children boarding or exiting the bus and the drivers.

In situations where there is such a divide, the law allows for vehicles traveling in the opposite direction to the stopped school bus to continue driving without stopping, as the children are not in immediate danger from oncoming traffic. This distinction is crucial to understanding traffic laws concerning school buses and the protections in place for student safety.

The other scenarios described do not provide the same level of separation or safe passage. For example, on one-way streets or unpaved roads, the conditions do not remove the requirement for drivers to stop when a bus has its signal lights activated, as the safety of the children remains a concern in both contexts.
