| dc.description.abstract | Although the drunk driving accident only accounts for small percentage, it causes a high proportion of casualties in the overall road traffic accidents and the social costs associated with them is far beyond imagination.
This thesis examines the effects of three statutory changes in drunk driving laws by using the A1 and A2 Road Traffic Accident Investigation Report of National Policy Agency during 2009 to 2016. The three statutory changes are the Article 185-3 of Criminal Code in 2011, the Article 35 of Road Traffic Regulations on Administrative Penalties in 2013, the Article 114 of Road Traffic Safety Regulations in 2013, respectively. The observation intervals of three months, half year, and one year are used before and after the implementation date of each statutory change. The number of drunk driving accidents, the number of casualties, and the distribution of alcoholic drinkers′ BrAC level are examined to evaluate the effect of each statutory change. The empirical analysis shows that the more severe the penalties, the lower the BrAC, the number of the drunk drivers in the traffic accidents, the ratio of daily drunk driving accidents, and the number of casualties after each statutory change. Furthermore, the BrAC distribution of the drunk drivers have shifted leftward after the Criminal Law amendment at June of 2013. That is, the number of heavily drunk driver is significantly reduced, while the number of mild/moderate drinking drivers is significantly increased. | en_US |
