with more and more cars coming into our families，we are happy that it has greatly improved our life. but unluckily，it has also brought many problems，such as heavy traffic and traffic accidents.
traffic safety is everybody's business. we must obey the rules. for example，we must walk on walk side，when we cross zebra – crossing，stop and look right and left，then go across fast. don't play football on the road .we can tell our parents not to drink before they drive，not to run through red lights，not to talk and laugh while driving etc.
we can say cars are coming into our life，but only when everybody thinks traffic safety is everybody's business can we be safe driving on roads and walking on sidewalks.
