This term is an inaccurate characterization of the problems caused by motorists who are impaired by alcohol. The first criminal laws targeting this problem prohibited "drunk driving," encouraging the notion that the problem was restricted to drivers who were visibly drunk. In fact, many alcohol-impaired drivers do not appear drunk in the traditional way. Research has shown that even small amounts of alcohol can impair the skills involved in driving, but the persistent notion that the problem is predominantly one of drunk drivers has allowed many drinking drivers to decide they are not part of the problem. For these reasons, the term "alcohol-impaired driving" is a more accurate and precise description of what is commonly referred to as drunk driving.
