Summary
This 1986 report, produced by the American Bar Association’s Criminal Justice Section, assesses the effectiveness of various legal sanctions and enforcement techniques aimed at reducing drunk driving. Motivated by the need for the legal profession to contribute tangible solutions to the drunk driving dilemma, the project sought to evaluate commonly used and emerging approaches from the perspectives of judges, lawyers, legislators, and researchers. The study aimed to identify which techniques offer potential for reducing alcohol-related accidents and to analyze their impact on the public, the legal system, and public awareness. The methodology relied primarily on the judgment and experience of justice system personnel rather than rigorous scientific evaluation. An eight-member Advisory Board, comprising judges, prosecutors, defense attorneys, and researchers, guided the project. The assessment involved conferences, seminars, and the review of existing literature and case law. The project analyzed twelve specific categories of sanctions and enforcement techniques, including sobriety checkpoints, "per se" laws, minimum drinking age laws, server liability, administrative license suspensions, and restrictions on judicial discretion in sentencing. For each technique, the report evaluated its effect on alcohol-related accidents, the public, the legal system, and public awareness. The provided text details the findings regarding sobriety checkpoints. Research indicates that well-designed checkpoints, particularly when combined with public information campaigns, offer a short-term general deterrent effect, though long-term impacts remain unknown. However, checkpoints are deemed highly inefficient for apprehending drunk drivers; for example, a large-scale effort in New York City resulted in over 184,000 stops but only 222 arrests. Public response is mixed, with acceptance dependent on minimizing intrusion and ensuring safety. Legally, checkpoints are subject to Fourth Amendment constraints. While the U.S. Supreme Court has not ruled directly on their constitutionality, most state courts have upheld them provided they are nondiscriminatory, limited in scope, and conducted with proper safety precautions. Some courts have struck down specific programs due to operational flaws or lack of evidence of effectiveness compared to less intrusive alternatives. The report concludes that no single "cure-all" exists for drunk driving. Regarding sobriety checkpoints, the authors recommend that if used, they must adhere to strict operational guidelines to ensure constitutionality and public acceptability, such as establishing written procedures, selecting locations based on accident data, and minimizing delay. The broader significance of the report lies in providing legislators, courts, and law enforcement with a comprehensive, impartial analysis of legal tools to combat drunk driving, highlighting the trade-offs between deterrence, efficiency, and civil liberties.
Key finding
Sobriety checkpoints offer short-term deterrence but are inefficient for apprehending drunk drivers, while the report generally finds that existing legal sanctions lack rigorous scientific validation for long-term effectiveness.
