Summary
This 1977 report, titled *Safety Belts: The Uncollected Dividends*, addresses the persistent problem of low safety belt usage despite the proven cost-effectiveness of belts as a highway safety measure. The authors argue that while the financial investment in vehicle restraint systems has already been made by automobile purchasers, the potential benefits in reduced injuries and fatalities remain largely unrealized. The manual was developed to provide state legislators and officials with a comprehensive set of techniques to encourage belt usage, framing the issue as a matter of collecting "uncollected dividends" in human welfare and economic savings. The development of the manual followed a rigorous consultative process. The authors from the University of North Carolina Highway Safety Research Center began with a literature review and internal staff interviews. They then conducted extensive personal and telephone consultations with a wide range of experts, including state officials, private organizations, insurance agents, and automotive manufacturers. The draft manual was subsequently pilot-tested in a workshop format with 20 state officials and legislators from seven states. Based on the detailed feedback from this workshop, the materials were rewritten and refined before final review by the National Highway Traffic Safety Administration (NHTSA). The resulting manual consists of 12 chapters designed to guide states in implementing a coordinated plan to increase belt usage. Chapter 1 provides an overview of belt effectiveness, explaining the physics of crash protection, such as the "ride down" benefit and the prevention of secondary impacts. Chapter 2 outlines the structure for a statewide coordinated plan, including executive committees and funding strategies. The remaining ten chapters focus on specific areas of state responsibility, proposing actionable techniques for each. These areas include Police Traffic Services, Accident Investigation, Traffic Records, Traffic Courts, Infant and Child Restraints, Periodic Motor Vehicle Inspection, Driver Licensing, Driver and Traffic Safety Education, Codes and Laws, and Public Information and Education. The report emphasizes that most proposed techniques can be implemented within existing authority, though some may require limited legislation. The significance of this work lies in its practical, multi-faceted approach to behavioral change and policy implementation. By linking specific techniques to the state agencies with primary responsibility, the manual offers a "shopping list" of strategies that states can adapt to their specific philosophies and goals. The report concludes that increased safety belt usage is the most cost-effective highway safety measure available, and that state authorities have a responsibility to utilize these feasible approaches to significantly reduce the toll of motor vehicle crashes, particularly among younger populations. The manual serves as a foundational resource for integrating safety belt promotion into existing state infrastructure, from driver education curricula to judicial proceedings and public information campaigns.
Key finding
The manual provides a comprehensive framework of techniques for state officials to implement, covering areas from police enforcement to public education, to increase safety belt usage.
