As a driver I have no authority on any discipline, all I can do is right the students up, it is then up to the principle to do the discipline! Sometimes the punishment doesn't fit the crime! Most of the kids know it, so they don't care if they get written up! I don't speed, nor would I use my phone, although I have seen bus drivers is other areas do it.
I couldn't imagine encouraging any students to get off the bus and fight, that is terrible, and the students that are fighting on the bus should be no where near each other, siblings or not!
