Assessing legal change: Recidivism and administrative per se laws

Tougher sanctions for drunk driving have often been advocated as a means to reduce this problematic behavior. In a test of administrative per se laws as a specific deterrent, the impact of introducing such laws is evaluated by examining reconviction rates of offenders before and after implementation of the Jaw in three states (North Dakota, Louisiana, and Mississippi), with comparisons made to a fourth state during the same time period that did not implement an administrative per se law (California). Recidivism is analyzed using survival models. The results indicate that administrative per se laws reduce rates of reconviction in some situations but not in others. In particular, if implementation of the law is accompanied by changes in overall rates of license actions, the specific deterrent effects of the law may be outweighed by the increased efficiencies of this judicial process.
