Can You Pass a Bus with Yellow Lights?: Understanding School Bus Signals and Safety

When you're driving and see a school bus with flashing yellow lights, it's often a moment of confusion: can you legally pass, or should you stop? Understanding the laws—and prioritizing safety—are key for all drivers.

In most places across the United States, yellow (or amber) flashing lights on a school bus are a warning that the bus is preparing to stop to either load or unload children. This is not the same as the red flashing lights with the stop arm extended, which means you must stop by law. Instead, while the yellow lights are flashing, drivers are generally required to slow down and be alert, but they may pass the bus—unless local or state law says otherwise. Some states have stricter regulations where you must not overtake a bus with yellow lights flashing, especially if children are nearby or crossing.

From a design perspective, whether marking school bus stops, planning safe drop-off zones, or arranging traffic patterns on residential streets, I always prioritize visibility and safety for children and drivers alike. Good planning and clear markings can enhance compliance with bus stop rules. If your community needs safer or more intuitive layouts at school zones or residential streets, tools like a Room Planner are invaluable for visualizing traffic flows and safety zones before any ground is broken.

Tips 1:

Always check your state's Department of Motor Vehicles website for specific school bus laws—some areas have unique requirements about stopping or passing.
