윤창호법의 음주운전 억제효과*

Abstract

This study is on the deterrence effects of two Yoon-Changho laws on drunken driving, which was acted after Yoon-Changho’s death by a drunken driver and strengthened punishment on drunken driving. Using the Korean police statistics about the number of death by traffic accidents, this study focuses on the changes of the number of death by traffic accidents between pre-act and post-act period. The results of analysis on this data show that the number of death by traffic accidents is significantly decreased 52% in First Yoon-Changho law and 61% in Second Yoon-Changho law, compared to control group (same period, 1 years ago), between pre-3 month and post-3 month. But, between pre-6 month and post-6 month, the number of death by traffic accidents is not decreased to a significant level, compared to control group in both laws. This result shows that two laws, that increased severity and certainty of punishment on drunken driving, have only a short-term effect, such as results of many existing researches.
