And school busses go all sorts of places carrying kids to field trips and sporting events. Along with police/fire/ambulances, school busses are just another special type of vehicle that ALL drivers must learn to deal with. If you cannot act properly around a school bus, you shouldnt be on the road.

(Funny story: i was in Ottawa over the winter. There, snow plows, ambulances and fire trucks all use blue flashing lights. I thought i was being pulled over by a giant police truck ... it was a snow plow that really did not appreciate me stopping on the side of the road. Yet another special case vehicle.)
