Summary
This document outlines the U.S. Department of Transportation’s (DOT) policy and implementation strategy for addressing speeding as a critical highway safety issue. The motivation stems from the significant threat speeding poses to public safety, contributing to approximately one-third of all fatal crashes and resulting in an estimated economic cost of $27.7 billion annually in 1998. The DOT’s overarching policy aims to provide guidance to state and local governments to set speed limits that maximize transportation efficiency while eliminating unnecessary crash risks. This approach promotes balanced programs utilizing cost-effective strategies, including reasonable speed zoning, public education, targeted enforcement, and advanced speed management technologies. The strategy is structured around three primary components: speed limits, enforcement, and research and demonstration. Regarding speed limits, the policy emphasizes that limits must be perceived as safe and reasonable to encourage voluntary compliance. It encourages the development of speed zoning guidelines through multi-disciplinary reviews and the adoption of variable speed limits and condition-responsive warning systems. The use of physical countermeasures, such as speed humps and rumble strips, is also promoted where speed poses a serious hazard. Enforcement efforts are directed toward high-crash locations where speeding is a contributing factor, with a focus on specific demographics and conditions, such as young drivers, nighttime driving, and adverse weather. These enforcement activities are intended to be complemented by vigorous public information and education campaigns to increase awareness of speeding consequences and support for traffic laws. The research and demonstration component seeks to better define the speeding problem by identifying when, where, and why speeding leads to crashes, including the demographics of offenders. Objectives include developing advanced technologies like vehicle-based radar warning systems and variable speed limit systems, as well as testing less labor-intensive enforcement methods. The strategy also calls for examining the effects of fines on habitual offenders, exploring corporate policies that may encourage speeding, and analyzing the impact of road design and vehicle characteristics on safe operating speeds. Additionally, the policy advocates for integrating speed management into broader highway safety initiatives, such as impaired driving and commercial vehicle safety programs, and developing targeted education campaigns for judges, prosecutors, and engineers. The significance of this document lies in its comprehensive, multi-faceted approach to reducing speed-related crashes. By combining engineering solutions, enforcement, education, and research, the DOT aims to create a sustainable framework for improving highway safety. The strategy underscores the importance of voluntary compliance and the need for continuous improvement in speed management technologies and policies to address the complex factors influencing driver behavior and crash risks.
