School bus drivers and cell phones

Do we really have to tell people things like this? Shouldn't someone with a license to drive a bus have figured this out by now?

WASHINGTON (AP) — The school bus industry has a message for bus drivers: Put down your cell phones.The American School Bus Council plans to issue guidelines Tuesday calling for a ban on drivers using cell phones when the bus is moving or when students are getting on or off.

... The federal panel made that recommendation after blaming a driver’s chat on a cell phone for a 2004 crash in Alexandria, Va. that injured 11 students.
