What do you do if the bus is stopped and has its red lights flashing?

A school bus has the authority to stop traffic with its flashing red lights and stop arm extended. You must stop. However, there is an exception to this whether or not oncoming traffic also has to stop... if there is a center median, only the side that the bus is on has to stop. No, the center lane is not a center median. For instance, if there's a center median on a north-south road and the bus stops with red lights flashing on the southbound side, the northbound can keep going because the center median separates the northbound from the southbound, the center median guards the kids from entering northbound traffic, which is why the northbound wouldn't have to stop.

If both side red lights are flashing, you stop behind the bus.
