In my opinion,it is necessary to ban on drinking and driving,it will do well,not only other people but also the drinker himself.
If we can continue to do this,will reduce the traffic accidents in the near future.
First,we must make posters and signs reminding people that it is wrong of drunk driving,which is an unhealthy drink at all.
Second,people love money,we can very good drink drunk driver,more money.
Finally,we can reduce the drunken driver's name.
People always care about their honor,so it will be a very useful way to stop them from drunk driving.
