We can see many traffic signs on both sides of the roads or streets.Some tell the drivers what to do,and others tell them what not to do.The traffic signs are the traffic rules.All people must obey the rules and mustn’t break them.
　　Each traffic sign has its meaning.Do you see the sign “P”?Do you know its meaning?
　　In big cities,there are a lot of cars,trucks and buses.They can’t stop on the streets at any time.If a driver wants to stop his car,he must look for a place for his car —a car stop.A car stop is like a special “hotel” and it is for cars to “live in”.For a driver,how does he find a “hotel” for his cars?The traffic sign “P” can help him.“P” is the first letter of the word “Park” and its meaning is “You can stop your car here!” After the driver finds the car stop,He can park his car there.And then he can do other things.
　　It’s very important to obey the traffic rules.If you live in the city and go to school by bike every day,you must be very careful,or you’ll have an accident.You can’t ride too fast,and you can’t let your classmate or friend sit behind you,either.You always have to stop at a stop sign.
