School bus safety starts with you, every morning and every afternoon. Take a few minutes to make

children are under the age of nine.
Make sure your children know these rules:
● Be on time.
● Never run to or from the bus.
● Stand away from the side of the road.
● Don't push.
● Stay in your seat.
● Don't shout.
● Always obey the driver.
● Wait for the driver's signal before crossing.

● Never crawl (爬行) under a school bus.
Make sure that an adult is present at the bus stop every day, especially with children under the age
of nine.
