The literature provides ample scientific studies on the relationship between impairment of driving skills and even moderate BAC levels. Even though lowering of the legal BAC limit has produced promising results internationally it has not been adopted in the USA. Since the legal BAC limit is so indulgent in USA, it is often erroneously believed that one may drive up to a BAC of 100mg/100ml, overlooking the fact that driving is impaired at lower BACs. However, it seems that when dealing with this sensitive issue, policy makers usually yield to the pressure or consideration of the current political environment rather than rely on scientific evidence. In this paper it is argued that a global traffic safety effort is needed. This effort must also include evolving improved technologies and even the alcohol, entertainment and media industries in order to change attitudes towards road safety. This brief presentation is based on three recent paper articles publicised in Japanese media. It concludes that lower legal limit should be one of the most important parts of a comprehensive approach to reduce alcohol impaired driving.
