Summary
This technical assistance report, conducted by the Louisiana Transportation Research Center for the Louisiana Department of Transportation and Development, addresses the growing problem of distracted driving in the United States. The study was motivated by the need to inform Louisiana’s 2017 Strategic Highway Safety Plan (SHSP), which designated distracted driving as a new emphasis area. With distracted driving accounting for significant fatalities and severe injuries in Louisiana, the report aims to synthesize the state of knowledge regarding measurement methods, prevention strategies, legislation, employer policies, and technologies to guide local safety initiatives. The authors conducted an extensive literature review of existing research, analyzing data from crash reports, observational studies, attitudinal surveys, enforcement demonstrations, naturalistic driving studies, and driving simulators. The review examined national trends, including the prevalence of distraction-related crashes, the effectiveness of various countermeasures, and the current landscape of laws and technologies. Specific attention was given to NHTSA data, such as the Fatality Analysis Reporting System and the National Automotive Sampling Systems, as well as large-scale naturalistic studies like the SHRP2 Naturalistic Driving Study. The findings reveal that distracted driving is a major contributor to crashes, with inattention playing a role in nearly 80% of crashes in naturalistic studies. Nationally, 16 states and four territories have primary enforcement bans on hand-held cell phones, while 47 states and four territories ban text messaging. High-visibility enforcement campaigns demonstrated significant short-term reductions in hand-held phone use, though long-term crash reduction results were mixed. Employer policies are emerging, supported by toolkits from organizations like the National Safety Council, but there is a lack of research data validating the effectiveness of commercial distracted driving technologies, which range from free apps to hardware costing up to $150. The report identifies five core strategy categories used nationally: improving data collection, education, enforcement and adjudication, engineering, and legislation. The significance of this report lies in its provision of a comprehensive baseline for Louisiana’s distracted driving efforts. It concludes that effective prevention requires a multi-faceted approach focusing on improved data collection, robust legislation and enforcement, infrastructure improvements, and targeted communication and outreach. By documenting the state of practices and highlighting gaps—such as the underreporting of distraction in crash data and the unproven efficacy of certain technologies—the report establishes a foundation for the Louisiana SHSP Distracted Driving Emphasis Area Team to develop evidence-based strategies and initiatives.
Key finding
Hand-held cell phone bans maintained long-term reductions in phone use but showed mixed results on crash rates, and there is no research data to support the effectiveness of current distracted driving prevention technologies.
