Summary
This study, conducted by the National Highway Traffic Safety Administration (NHTSA), evaluates the effectiveness of publicized insurance sanctions as a general deterrence countermeasure for Driving While Intoxicated (DWI). The research was motivated by the need to assess whether communicating severe financial penalties—specifically increased auto insurance premiums—could reduce drunk driving among drivers who had never been convicted. Unlike specific deterrence, which targets repeat offenders, general deterrence relies on public awareness of the certainty and severity of sanctions to influence behavior. The study aimed to measure changes in public awareness and self-reported drinking and driving behaviors following a targeted publicity campaign. The experimental design utilized a controlled test in New Hanover County, North Carolina, with Buncombe County serving as a comparison site. North Carolina was selected because it mandates a consistent 400 percent surcharge on insurance premiums for three years following a DWI conviction, ensuring the sanction was severe and uniformly applied. The intervention consisted of a seven-month public information and education (PI&E) campaign launched in November 1990. This campaign relied heavily on television public service announcements (PSAs), radio spots, and posters, emphasizing that convicted offenders would face substantial insurance increases. Data collection involved surveys administered by the North Carolina Division of Motor Vehicles to drivers visiting licensing offices in both counties prior to, during, and after the campaign. These surveys measured awareness of the insurance sanctions, knowledge of DWI consequences, and self-reported frequency of driving after drinking. The findings indicated that the PI&E campaign successfully reached a portion of the target audience. Approximately four percent of drivers reported seeing the message, with an additional four percent possibly exposed. Among those who saw the advertisements, about half correctly identified the insurance sanction as a consequence of a DWI arrest. Regarding behavioral impact, many drivers who became aware of the insurance sanctions reported that they drove less often after drinking. The study also noted that insurance sanctions were cited as one of the most feared consequences of a DWI conviction among those aware of the program. However, the text does not provide specific statistical data on crash reductions or precise behavioral change metrics beyond these self-reported trends. The significance of this research lies in its contribution to the understanding of general deterrence strategies for DWI. The study demonstrates that publicizing severe, consistently applied insurance sanctions can increase public awareness and potentially influence driving behavior. By showing that financial penalties imposed by private insurers can serve as an effective deterrent when properly communicated, the findings support the integration of insurance sanctions into broader DWI reduction programs. The report concludes that such measures, when part of a comprehensive system including enforcement and other sanctions, offer a viable tool for mitigating drunk driving, provided that the sanctions are severe, swift, and sure.
