#1 - School Bussing
In lots of school districts kids are bussed, and while this is usually the safest way to get to and from school, a few precautions can make it even more so. Kids shouldn't cut it too close when they're headed for the bus stop -- the goal is to be there in plenty of time and limit any goofing off.
The bus driver is the boss, so whether they're giving a signal on when it's safe to cross or some other instructions, they must be obeyed. Kids need to stay out of the bus driver's blind spots and walk where they can be seen. They should also be taught to always cross carefully, never darting out from between parked cars or expecting other vehicles to stop for them.
