When you see a school bus stopped with its red lights flashing and its stop arm extended, you must _________ unless it is stopped on the opposite side of a separated (divided) roadway.

If you see a school bus is stopped with its red lights flashing and its stop arm extended, you must stop at least 20 feet from the bus. However, you are not required to stop for a school bus with its red lights flashing if it is on the opposite side of a separated (divided) roadway.
