With the development of the modern technology，private car is no longer a luxurious thing for ordinary people，more and more people drive to work instead of going by bus. The popularization of private car has many advantages.First， it is very convenient and time-saving ，you can drive your own car to the workplace instead of waiting for the crowded bus and afraid of being late for working.Second，it can also improve the traffic structure，and help to mitigate the stress of the traffic.Third， the popularization of private car can help to promote the car industry and any other interrelated industries. I believe that in the future the private car will become the most important vehicle and we cann't live without it.
Every year a lot of people are killed or injured in road accidents. How can we make the roads safer? Remember the following traffic rules.
When you ride a bike, keep to the right side of the road. Don’t cross the road or turn left at a red traffic light. Give a hand signal if you want to turn or stop.
Before crossing the road, stop and look both ways, right and left. If the road is clear, it is safe to cross. The correct way to cross is to walk quickly, but not to run. If you run across the road, you may fall down.
If you see small children or old people waiting to cross the road, it is a kind deed to help them to cross in safety. We should teach small children not to play or ride on the roads.
Always obey these rules, you’ll find it much safer to walk or ride on the road.
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.
