Summary
This report evaluates West Virginia’s participation in the National Impaired Driving High Visibility Enforcement Campaign, a program coordinated by the National Highway Traffic Safety Administration (NHTSA). West Virginia was selected as one of 13 Strategic Evaluation States due to its high alcohol-related fatality rates. The campaign, which began during the July 4th holiday period in 2003 and was evaluated through September 2005, aimed to reduce impaired driving and associated fatalities. The intervention followed the NHTSA model, comprising three primary components: enhanced enforcement during summer and winter holidays, sustained enforcement between holidays, and media campaigns delivering strong enforcement messages. Enforcement activities focused on six targeted counties, utilizing sobriety checkpoints and saturation patrols to cover 85 percent of the state’s population. The evaluation methodology included driver licensing office surveys, public awareness telephone surveys, roadside surveys measuring blood alcohol concentrations (BACs), and time-series analysis of fatality data. Enforcement intensity was high, with 810 activities conducted in targeted counties from 2003 to 2005, averaging approximately seven activities per week during crackdowns. Media efforts targeted young men aged 21 to 34, a demographic overrepresented in alcohol-related crashes, utilizing both federal and state-funded paid media. Roadside surveys collected voluntary, anonymous BAC samples from drivers at checkpoints across 11 months between 2004 and 2005, yielding over 4,000 samples. Results indicated significant improvements in public awareness and behavioral outcomes. Surveys showed a statistically significant 29.7 percentage point increase in respondents from targeted counties who reported seeing or hearing anti-impaired driving messages between 2003 and 2005. Recognition of the campaign slogan increased by 41 percentage points. Direct observations revealed a statistically significant 2.8 percentage point decrease in drivers with a positive BAC from mid-2004 to mid-2005, with male drivers showing a specific 3.2 percentage point reduction. Crucially, ARIMA modeling of fatality data demonstrated a significant, sustained decrease in alcohol-related fatalities in targeted counties starting in July 2003. The analysis estimated that the campaign saved approximately 18 lives over an 18-month period, equating to a reduction of 0.98 lives per month. While reductions were observed in the targeted demographic of men aged 21 to 34, this specific subgroup reduction was not statistically significant. The study concludes that implementing the full NHTSA impaired driving campaign model significantly reduced both the prevalence of drivers with positive BACs and the trend of alcohol-related fatalities in West Virginia’s targeted counties. The findings validate the effectiveness of high-visibility enforcement combined with targeted media campaigns in reducing traffic fatalities. The estimated saving of 18 lives underscores the potential impact of such coordinated strategies in states with high alcohol-related crash rates.
Key finding
ARIMA modeling estimated the campaign cut alcohol-related fatalities by about 0.98 per month over 18 months, roughly 18 lives saved in targeted counties, alongside a significant 2.8-point drop in positive-BAC drivers.
