There will be more drivers dropping off kids and all those big school buses to share the road with come Monday. But when is it OK to pass a school bus and when do you have to stop?

School bus safety class is now in session.

On a divided highway of 4 or more lanes with a median, only cars behind school bus need to stop when it stops.

On a two lane road, vehicles in both directions must stop for a bus.

On a four lane road without a median, again, vehicles in both directions must stop.

On a roadway with four or more lanes where there is a center turning lane, only the cars behind the bus need to stop.
