What is necessary when traveling on a divided highway with a school bus?

When traveling on a divided highway with a school bus, it is necessary for only the vehicles behind the bus to stop. This is due to the structure of a divided highway, where physical barriers or medians separate opposing lanes of traffic. Because of this separation, vehicles approaching from the opposite direction do not pose a hazard to children getting on or off the bus. As a result, only those vehicles directly behind the bus are required to stop when the bus has its flashing lights activated. This rule helps ensure that children can safely board or exit the bus without the risk of being struck by oncoming traffic from the opposite side of the divided highway.
