RCW 46.61.370 describes what drivers should do when meeting a school bus that is stopped and has its red light flashing and the "stop" showing.
All vehicles traveling in the same direction must stop. But you need not stop if you are travelling in the opposite direction on a divided road or a road with three or more lanes.
So you do not need to stop for school buses on Ruddell Road when travelling in the opposite direction. Please look up the law and stop blocking traffic.
