Dear school parents,
We are happy that you are spending the time talking to your children about the importance of school bus safety (安全). The school bus is one of the safest forms of transportation, but every year children are injured (受伤的) in school bus accidents (事故) all around the world.
Education is the key to prevention (预防). During National School Bus Safety Week each October, we organize (组织) an event called “Operation Safe Stop”. We need your help to tell the children about the basic school bus safety rules (规则). Please take some time to speak to your children about the following school bus safety rules:
Be on time.
Never run to or from the bus.
Don't push or shove (乱推) on the bus.
Stay in your seat on the school bus.
Don't yell (喊叫) or speak loudly on the bus.
Always obey (服从) the driver.
Always cross at least 10 feet in front of the bus.
Never crawl (爬行) under a school bus.
