Stop for a school bus on a divided highway
Drivers approach a stopped school bus on a divided highway and often hesitate because the obligation to stop depends on how the route segment is physically separated. The rule generally turns on the presence of an intervening median, barrier, or unpaved space, not merely on the number of lanes. Understanding that road classification and lane layout decide the duty helps a motorist respond correctly to traffic signs, flashing lamps, and the extended stop arm without either stopping unnecessarily in fast traffic or risking a violation where children may cross.
Essential answer
On a divided highway, traffic traveling in the opposite direction from a stopped school bus is usually not required to stop when a physical median or barrier separates the opposing roadways. The median must be a raised or depressed strip, guardrail, concrete divider, or unpaved area that creates a distinct access restriction between the two directions. If the highway merely has a center turn lane, painted lines, or a flush paved separator, drivers in both directions generally must stop because pedestrians could still cross the full width of the road.
The same duty still applies to vehicles moving in the same direction as the bus on either side of the divider. Those drivers must stop before reaching the bus and remain stopped while the red lights flash and the stop signal is displayed. The divided-highway exception addresses only approaching traffic on the far side of the physical separation, because that traffic is not expected to encounter children crossing from the bus toward the opposite roadway. Travel conditions such as curves, shadows, or fading light do not remove the need to identify the median type before deciding whether the law requires a stop on that segment.
