First of all,the people in China seldom obey the traffic rules when they are in hurry.Those who break the rules are because of convenience.If everyone knows that breaking the traffic rules means hurting both himself/herself and others,they should not risk doing like that.
Secondly,the laws related to the traffic accidents are not as clear as a bell.Many people ignore the laws and break it on purpose,like driving after drinking a lot.Without restrict laws,people dare to risk for convenience.
Thirdly,many people don't care for his/her life.They don't know how to prevent accidents or how to protect himself/herself.If everyone takes a deep thought before doing one thing,they are not likely getting hurt.
