Summary

This research note examines the prevalence and characteristics of driver distraction in motor vehicle crashes using data from various National Highway Traffic Safety Administration (NHTSA) databases and studies. The study was motivated by the serious safety risks posed by distraction, which includes secondary tasks like cell phone use, eating, and interacting with passengers, as well as cognitive distractions like daydreaming. The primary goal was to provide a comprehensive overview of distraction-related fatalities, injuries, and crash involvement rates to inform the development of behavioral and vehicle safety countermeasures. The analysis utilized multiple data sources to capture different perspectives on distraction. Fatal crash data were drawn from the Fatality Analysis Reporting System (FARS), a census of all fatal crashes, while injury and property-damage-only crash estimates came from the National Automotive Sampling System General Estimates System (GES), a nationally representative sample. To address limitations in police-reported data, the note also incorporated findings from the National Motor Vehicle Crash Causation Survey (NMVCCS), which involved on-scene investigations of 5,471 crashes, and the 100-Car Naturalistic Driving Study, an observational study of 100 instrumented vehicles. Additionally, data on electronic device usage were sourced from the National Occupant Protection Use Survey (NOPUS) and the Motor Vehicle Occupant Safety Survey (MVOSS). The authors note that police-reported data likely undercount distraction due to reliance on self-reporting and inconsistent reporting practices across jurisdictions. The findings indicate that distraction is a significant factor in traffic crashes. In 2008, distraction was reported in 16% of fatal crashes, resulting in 5,870 fatalities, and in an estimated 21% of injury crashes, involving 515,000 injured people. The proportion of fatal crashes involving distraction increased from 12% in 2004 to 16% in 2008. Drivers under the age of 20 had the highest proportion of distraction involvement in fatal crashes (16%), followed by those aged 20–29 (12%). The NMVCCS found that distraction was the critical reason for approximately 18% of crashes where the driver was at fault. The 100-Car Naturalistic Driving Study revealed that secondary task involvement contributed to over 22% of all crashes and near-crashes. Survey data indicated that in 2007, 11% of vehicles during daylight hours were being driven by someone using an electronic device, and 81% of drivers aged 16 and older had a wireless phone in their vehicle. The significance of this research lies in its synthesis of varied methodologies to quantify the scope of distracted driving, highlighting that official statistics likely underestimate the true prevalence of the problem. The data underscore the particular vulnerability of young drivers and the growing role of electronic devices in crash causation. By providing these statistics, the report supports NHTSA’s efforts to develop targeted countermeasures and policies to mitigate the risks associated with driver distraction, emphasizing the need for improved data collection methods to better understand and address this safety issue.

Key finding

Driver distraction was reported in 16 percent of fatal crashes and estimated to be involved in 21 percent of injury crashes in 2008, with drivers under age 20 exhibiting the highest rate of distracted driving among fatal crash participants.
