An operator on a highway with separate roadways is required to stop for a school bus under which condition?

The requirement for an operator on a highway with separate roadways to stop for a school bus is determined by the position of the bus relative to the roadway that the operator is on. When a bus is actively loading or unloading passengers, any vehicle traveling on the same roadway must stop regardless of other conditions. This is crucial for the safety of children boarding or leaving the bus.

Stopping for a bus that is on the same roadway ensures that children can move safely between the bus and the sidewalk without the risk of being struck by vehicles. This is especially important in school zones where pedestrian traffic can be significant.

In contrast, if the highway has separate roadways and the bus is on a different roadway, vehicles on that separate roadway are not required to stop. This is designed to maintain traffic flow while still prioritizing the safety of children when they are near the bus.
