Traffic safety is everybody's business. Records show       every year a lot of people die in traffic accidents. Some of the accidents are due     mechanical problems. However, most of them are the results of careless      reckless driving, and could be avoided. A lot of people disregard traffic signals and rules. They drive regardless of speed limits, run through      lights, drive in the wrong direction, talk and laugh while   , and turn as they wish without giving signals. They    slow down while approaching(接近) crossroads. So many people violate traffic regulations that we cannot put too much emphasis on     importance of traffic safety. Only when everybody thinks traffic safety is everybody's business can we be safe driving on roads and walking   sidewalks（人行道）
