Summary
This report details a demonstration project conducted in Joplin, Missouri, aimed at building community support for sustained high-visibility enforcement (HVE) of impaired-driving laws. The initiative was motivated by the recognition that while periodic national mobilizations effectively reduce fatalities, many law enforcement agencies limit enforcement to these specific windows. This inconsistency can lead community members to underestimate the risk of detection and the severity of the problem. The project sought to establish a model for year-round enforcement by fostering a coalition of community stakeholders to modify social norms, increase acceptance of enforcement, and ultimately reduce impaired driving. The Joplin Police Department (JPD) convened the "Joplin Community Partners," a coalition comprising representatives from healthcare, media, education, legal sectors, and organizations like MADD. Over five months, this group developed a 15-month strategic plan encompassing enforcement, media, and public outreach. The enforcement phase ran from May 2018 to August 2019, coordinating with statewide mobilizations and focusing on high-risk periods. Due to a lack of funding for paid media, the strategy relied heavily on earned media and social marketing, utilizing the JPD’s Facebook page and local news outlets to publicize enforcement activities under the theme “We’re out there too. Drive Sober or Get Pulled Over.” Baseline data indicated that traffic crashes and impaired-driving incidents had been increasing in Joplin since 2015. During the 15-month period, the JPD issued 5,798 traffic citations and made 1,005 arrests, including 227 impaired-driving arrests. This represented an increase in enforcement activity compared to the preceding year. Social media efforts generated significant engagement, with 66 Facebook posts receiving over 16,000 likes and 4,400 shares, alongside positive community feedback. Traffic data showed that overall crashes decreased during the project period, while impaired-driving crashes remained stable compared to the immediate pre-enforcement baseline. However, the project faced challenges, including officer resignations that limited personnel resources and insufficient participation from some community partners in planned outreach events. Despite these operational successes, an independent evaluation concluded that the program did not generate enough activity to significantly increase community support for sustained impaired-driving enforcement. The report highlights that while the project strengthened the JPD’s capacity for continued enforcement and successfully publicized efforts, the broader goal of shifting community norms and securing long-term public backing for year-round enforcement was not fully achieved. The findings suggest that while HVE is effective, building the necessary community infrastructure to support sustained enforcement requires more intensive and consistent engagement than was realized in this demonstration.
Key finding
An independent evaluation found that despite increased enforcement and stable crash rates, the demonstration project did not generate enough program activity to increase community support for sustained impaired-driving law enforcement.
