How should a driver react to a school bus stopped with red lights flashing on their side of the road?

Answer: A — Come to a complete stop

When a school bus is stopped with its red lights flashing, it indicates that it is either picking up or dropping off children. In this situation, drivers must come to a complete stop, regardless of which side of the road they are on, to ensure the safety of the children. Passing the bus or attempting to speed past it while the red lights are flashing is dangerous and illegal in order to prevent accidents and potential harm to the children crossing the road. The correct answer is to come to a complete stop when encountering a school bus with red lights flashing.
