In this paper, we want to talk about the history of criminal policy on driving under the influence of alcohol(DIU), criticize the existing policy by comparing it with other criminal policies in other countries, and then show ways to improve this policy. If we conclude the above, it is like this. The history of criminal policy has been a strict sticking to expansion and reinforcement of criminal punishment and a periodic general crackdown. Namely the policy that we have been enforcing was only relying on the things that were mentioned above. On the other hand in other countries like America, England, Germany, Japan and so on, they have been running various preventive policies and prevention of second offence programs in addition to crack downs and punishment, and by this they have had quite a success in reducing harms and accidents. Accordingly we need to make an improvement by using more diverse policies, like prevention, crackdown, punishment, treatment, and rehabilitation, which not only the police but government and citizens can also participate in, by looking at the precedents of other countries. In it`s final analysis, it is not good for criminal policy to only rely on crackdowns and strong criminal punishment, but not only do we need to use preventive policies and prevention of second offence but we also need to adopt real time monitering system for drunk or dangerous driving while government and citizens also participate fully. Only then will we get the anticipated results.
