The Effectiveness of a New Law to Reduce Alcohol-Impaired Driving in Japan

This article reports on a research study undertaken to determine the effects of a new traffic law in Japan, implemented in June 2002, that lowered the acceptable blood alcohol concentration (BAC). The authors used police data regarding traffic fatalities and injuries for 7 months (June - December 2001) prior to the law's enforcement and for 7 months after the enforcement (June - December 2002). Results showed that after the implementation of the law, traffic fatalities decreased by 7.8%, and the traffic fatalities involving drunken driving decreased by 26.7%. The authors conclude that the new road traffic law was immediately followed by a substantial decline in fatal and non-fatal motor vehicle injuries associated with alcohol-impaired drivers, and an overall decrease in motor vehicle deaths and injuries. Thus, this new legislation is considered to be a very successful public health measure.
