Recently I have learned from the internet that traffic accidents were happened frequently, which mainly resulted from drinking driving.

Many drivers think they are luckily to avoid accidents. As the matter of fact, no one could afford to risk their lives driving after drinking. Drunk driving will not only threaten the life of the drivers as well as other people, and also make their family suffer from anxiety caused by it. In addition, drunk driving against the law and more and more people are punished for them.

In a word, for the sake of the safety of all people, please not drive after drinking.
