Do you go to school by bus? It is very important for you to know how to be safe when taking a bus, no matter whether you like it or not.

First, don’t run to the bus stop, but walk. While you are at the bus stop, you should wait in a safe place. Do not run or play while waiting. And never get into a car with a stranger.

Second, don’t talk in a loud voice when you are on the bus, so the driver will not be disturbed(打扰). If you need to talk with the bus driver, you’d better wait until the bus stop. Never throw things on the bus or out of the windows. Never play near the emergency exit. When there is a fire, the most important thing is to break the window with a hammer or any sharp things and then jump out.

Third, when you are getting off the bus, make sure you walk(not run) three more steps away from the door. This is the best place to be around a bus. Stay away from the bus wheels and watch out for moving cars!

Last, if you leave something on the bus, never return to the bus to get it. The driver may not see you come back and he may begin moving the bus. Also, if you drop something near the bus, tell the driver before you try to pick it up, so he will know where you are.
