Summary
This study, conducted by the University of North Carolina Highway Safety Research Center for the National Highway Traffic Safety Administration, assesses the impact of publicizing administrative license revocation for Driving While Intoxicated (DWI) in Nevada. The research was motivated by the observation that while Nevada adopted administrative license revocation laws in 1983 to ensure swift and certain sanctions, initial analysis showed no significant reduction in alcohol-related crashes. This lack of effect was attributed to low public awareness of the law and a lack of confidence in its enforcement. The study aimed to determine if a targeted public information and education (PI&E) campaign could generate a general deterrent effect by increasing awareness of the sanction’s severity, certainty, and swiftness. The project involved a comprehensive PI&E campaign implemented between April 1986 and May 1987. The campaign emphasized the theme "If You Drink and Drive in Nevada, the First Thing You Lose is Your License," highlighting that licenses are confiscated at the time of arrest for drivers with a blood alcohol concentration of .10% or higher, or those who refuse testing. Components included over 115,000 distributed brochures, television and radio public service announcements, billboards in major urban areas, and key chains. The campaign was coordinated with existing enforcement efforts, such as sobriety checkpoints and the REDDI (Report Every Drunk Driver Immediately) program. Data collection included time-series analysis of crash data, analysis of DWI recidivism patterns, and surveys of driver perceptions conducted before and after the campaign. The results indicated that the fully implemented PI&E campaign led to statistically significant reductions in alcohol-related and nighttime crashes. Specifically, alcohol-related crashes decreased by 12 percent. Survey data revealed increased public awareness of the administrative revocation sanction and a stronger expectation that it was being applied. Additionally, there were reported reductions in drinking-driving behavior among surveyed drivers. Implementation data showed that the administrative process resulted in a nearly fourfold increase in license revocations compared to the previous legal framework, with 9,341 revocations recorded in 1984, the first full year under the new law. The study concludes that administrative license revocation, when combined with well-publicized enforcement, can effectively reduce alcohol-related crashes through general deterrence. The findings suggest that the mere threat of swift and certain license loss, when widely understood by the driving public, serves as a powerful deterrent. The report implies that jurisdictions implementing similar administrative sanctions should prioritize public information campaigns to ensure the deterrent potential of the law is realized.
Key finding
Alcohol-related crashes were reduced by 12 percent following the implementation of a public information campaign emphasizing administrative license revocation.
