Summary

This report, mandated by Section 31105 of the 2012 Moving Ahead for Progress in the 21st Century (MAP-21) Act, addresses the growing public safety crisis of distracted driving. The primary objective is to examine the effects of all forms of driver distraction, identify metrics to determine the scope of the problem, and recommend strategies to reduce resulting deaths and injuries. The report defines distraction as the diversion of attention from the driving task to secondary activities, categorizing these into visual, manual, and cognitive types. It highlights that while electronic devices like cell phones are a major concern, non-technology-based distractions such as interacting with passengers, eating, or reaching for objects also significantly impair driving performance. The analysis relies on a comprehensive review of existing research, including naturalistic driving studies, observational surveys, and crash data. Key data sources include the National Highway Traffic Safety Administration’s (NHTSA) National Motor Vehicle Crash Causation Survey (NMVCCS), the 100-Car Study, and the National Occupant Protection Use Survey (NOPUS). The report evaluates various methodologies, noting that crash risk assessment is complicated by inconsistent police reporting, while observational and experimental methods provide critical insights into the frequency and performance degradation associated with specific tasks. For instance, the 100-Car Study utilized instrumented vehicles to calculate odds ratios for crash risk associated with secondary tasks, revealing that reaching for a moving object carried an odds ratio of 8.82, significantly higher than talking on a hand-held device (1.29). The findings indicate that distraction-affected crashes result in approximately 3,000 deaths and 400,000 injuries annually, with an economic cost of roughly $22 billion. Text messaging is identified as particularly dangerous due to its simultaneous visual, manual, and cognitive demands. Young drivers (18–20 years old) exhibit the highest incidence of crash involvement while using cell phones and are significantly more likely to text while driving than older demographics. Observational data from 2011 showed that 5% of drivers were using hand-held phones at any given daylight moment, translating to 660,000 vehicles. Furthermore, internal distractions, such as conversing with passengers, were the most frequently recorded source of distraction in crash-involved drivers, accounting for 57% of internal distraction cases in the NMVCCS data. The report concludes with recommendations for a multi-faceted approach to mitigation, including enhanced education, high-visibility enforcement campaigns, and the implementation of cell phone and text messaging laws. It emphasizes the need for improved data collection standards, such as the Model Minimum Uniform Crash Criteria, to better track distraction trends. Additionally, the report advocates for vehicle technologies that minimize workload demands and advanced crash avoidance systems. It underscores that while legislative and enforcement measures are critical, addressing the behavioral aspects of distraction through public awareness and technological interventions is essential for reducing the substantial toll of distracted driving on road safety.

Key finding

Reaching for a moving object resulted in an odds ratio of 8.82 for crash or near-crash involvement, while reading while driving had an odds ratio of 3.38, both significantly higher than normal driving.
