It was probably a textbook example of what to do when an accident happens. She made sure all the students were OK, then she got up and made sure the children exited properly out of the back of the bus like they are supposed to and lined them off to the side in a safe area.
The children were seated and well behaved through the whole ordeal. When it was finally over with the driver made sure all the children were OK and they exited out of the back. A couple of the older students helped the younger students out the back door.
