So, what exactly should you talk about? Most important, explain that there's a danger zone around the bus. Unless they're five big steps away from the bus, the driver won't be able to see them. (That's ten feet for little legs.) The danger zone matters when crossing the street in front of the bus, walking away from the bus, or if they should drop something on the ground near the bus.

Kids should also be taught that when they ride the bus, the same rules apply as when they're in the car: they should mind the driver and their manners. They should know not to play with the emergency exit door, not to block the aisle, and not to distract the driver by yelling, playing, or fighting.

If your kids are walking to the bus stop on their own, they'll need to know the rules for that, too. Here are three big ones:

• Stay on the sidewalk. If there isn't a sidewalk, walk on the left side so drivers can see you better.
• When the bus comes, take five big steps away from the road.
• Don't talk to strangers.

Riding the bus could seem exciting or scary to your kids. Either way, taking some time to talk with your kids before they start riding the bus can help them adjust. Don't stop there, though. Keep the conversation going so you can make sure they're following these important safety rules.
