作文要求：Write about three causes of car accidents
As we all know, there are many traffic accidents all over the world. In particular, some car accidents are very serious. However, most car accidents are due to the drivers. Some drivers play their cell phone games while driving, some drivers talk with others while driving, and some drivers feel very tired but still drive. These causes will lead to car accidents. It is a very bad habit to play cell phone games or use the cell phone while driving. Someone may say that I have such an important thing that I need use the cell phone. At any time the person’s life is the most important thing. Using the cell phone is dangerous. It is not only for you, but also it is dangerous for other car’s drivers and passengers. Since you play or use your cell phone, you can’t keep your eyes on the road and your car may hit other cars. It is also a cause of car accidents by talking with others while driving. Some drivers talk with others while driving. They may say we are old drivers. It is safe for us. Although they are old drivers, you might have a car accident. Why? The reason is that some traffics are very complex. If you are not careful, you may have an accident although you are an old driver. The worst habit is that you feel very tired and you do not have a break. You still drive. This is very bad for you. If you feel tired and you are still driving, you will sleep while driving. That is very terrible. Whenever you feel tired and whatever you have a significant thing, you have to stop on the right side, and then take a break. It is very significant for everyone who drivers the car on the road, or you will have a serious car accident. Above all, using a cell phone while driving, talking with others while driving, and feeling tired while still driving are the three causes of car accidents. These causes can all be avoided. Consequently, you can avoid car accidents.
