After stopping for a school bus, it is safe to proceed again when:

• A. The bus resumes motion but red lights stay flashing
• B. The bus stops and you may go when they stop flashing
• C. The bus disappears and you may proceed
• D. The bus has resumed motion and the red lights have stopped flashing

Answer: (D)

Red flashing lights on a school bus mean you must stop, and you should only proceed once the bus has started moving again and the red lights have stopped flashing. This ensures the area around the bus is clear and children have finished crossing. If the bus is still flashing red or hasn’t begun to move, you must stay stopped. If the bus has disappeared or the lights are off while the bus signal isn’t clearly resolved, you can’t rely on that as a cue to go. The safe signal to go is when the bus has resumed motion and the red lights have stopped flashing.
