With more and more cars come into our families, we are happy that it has greatly improved our life. But unlucky, it has also brought many problems, such heavy traffic and traffic accidents.
Traffic safety is everybody’s business. We must obey the rules. For examples, we must walk on the sidewalks. When we cross zebra–crossing, stop and look right and left, and then go across fast. Don’t play the football on the road. Beside, we can tell our parents not to drink before we drive, not to run through red lights, not to use cell-phones while driven etc.
We can say cars are coming into our life, but only when everybody thought traffic safety is his or her business can we be safe driving on roads and walk on sidewalks.
