Evaluation of Maine's Lower BAC Limit for Convicted OUI Offenders

This Traffic Tech briefly summarizes the findings of a study by Mid-America Research Institute that examined Maine's lower blood alcohol concentration (BAC) limit for convicted Operating under the Influence of Intoxicants (OUI) offenders. In 1988 Maine lowered its BAC limit for convicted OUI offenders from .10 to .05 for a period of two months post-conviction. The law mandated an administrative license suspension but did not establish .05 as a criminal offense. In 1995, Maine revised its lower BAC law and reduced the limit for convicted OUI offenders to .00 BAC for one year after a first offense. Adjudication and sanctioning are conducted through an administrative process. The study examined (a) Maine's process of detecting and arresting convicted OUI offenders driving with alcohol in their systems and (b) analyses of recidivism and crash data. It was found that the lower BAC law for OUI offenders does not seem to have created significant procedural or processing problems in Maine. Little impact on recidivism was found. Convicted OUI offenders in fatal crashes, as a percent of all drivers in fatal crashes, decreased by 45%, from 12.9% to 7.1% after 1988 (p=.059), and decreased still more after 1995. The lower BAC limit for convicted OUI offenders seems to be an important element in Maine's effort to decrease alcohol-impaired driving.
