This revision resulted in an increase in the proportion of DUI convictions, and reduction in the number of DUI citations reduced to reckless driving, a reduction in the proportion of offenders acquitted and/or dismissed, an increase in the proportion of revocations, and an increase in court referrals to an educational program on the first offense. However, the 1980 revision was accompanied by a significant increase in the percentage of alcohol-related accidents. Consequently, the Alabama Legislature revised the 1980 law on July 29, 1983, the revision taking effect immediately. The more stringent penalties in the new law apparently had a positive effect on all six alcohol-related measures cites above. Most importantly, the latest revision was accompanied by a significant decrease (2.8 percent) in the proportion of alcohol-related accidents. (Author abstract)
