You must ________ for a school bus that is stopped with its red lights flashing on the opposite side of the road.

Explanation

You must stop for a school bus that is stopped with its red lights flashing, whether it is on your side of the road or the opposite side. The only exception is if the school bus is stopped on the opposite side of a roadway that is divided by a barrier or unimproved median. In that case, you do not need to stop.
