Here is some of the latest research on distracted driving, with the focus on cell phone use and text messaging.
Fatalities of Pedestrians, Bicycle Riders and Motorists Due to Distracted Driving Motor Vehicle Crashes
J. Stimpson, F. Wilson, R. Muelleman, University of Nebraska Medical Center. Analysis of U.S. fatalities, 2005-2010. November 2013.
Quote: “Distracted drivers are the cause of an increasing share of fatalities found among pedestrians and bicycle riders. … 18.6% of the distracted driving-related crashes were cell phone-related.”
Impact of Hand-Held and Hands-Free Cell Phone Use on Driving Performance
G. Fitch, S. Soccolich, F. Guo, etc., Virginia Tech Transportation Institute for U.S. Department of Transportation. “Naturalistic driving study” backed by cell phone records. April 2013.
Quote: “Talking on a cell phone, of any type, was not associated with an increased safety-critical event risk. … Visual-manual subtasks (such as dialing) performed on a handheld cell phone were associated with an increased (crash) risk … and significantly increased the percentage of time drivers took their eyes off the forward roadway. … About half of the hands-free cell phone interactions involved visual-manual subtask.”
Crashes Involving Cell Phones: Challenges of Collecting and Reporting Reliable Crash Data
National Safety Council. Comparison of crash reports to data in Fatal Analysis Reporting System. May 2013.
Quote: “There is strong evidence to support that underreporting of driver cell phone use in crashes is resulting in a substantial underestimation of the magnitude of this public safety threat. … There is no reliable method to accurately determine how many crashes involve cell phone use; therefore, it is impossible to know the true scope of the problem.”
Texting Bans and Fatal Accidents on Roadways: Do They Work?
R. Abouk, S. Adams, University of Wisconsin. Analysis using fatality data. April 2013.
Quote: “Bans appear moderately successful at reducing single-vehicle, single-occupant accidents if bans are universally applied and enforced as a primary offense. Bans enforced as secondary offenses, however, have at best no effect on accidents. This is suggestive of drivers reacting to the announcement of the legislation only to return to old habits.”
Teens and Technology 2013
Mary Madden, Amanda Lenhart, etc. Pew Internet Project. Phone survey of 802 teens and parents. March 2013.
Quote: “Smartphone adoption among American teens has increased substantially and mobile access to the internet is pervasive. … Among teen smartphone owners, half are ‘cell-mostly’ Internet users.”
Pedestrian Injuries Due to Mobile Phone Use in Public Places
J. Nasar, D. Troyer. Ohio State University and DOT. Study of emergency room injuries, 2004-2010, nationwide. August 2013.
Quote: “Mobile-phone related injuries among pedestrians (paralleled or exceeded) the increase in injuries for drivers. … Using a mobile phone while walking puts pedestrians at risk of accident, injury or death.”
Mobile Device Use While Driving: U.S. and 7 European Countries
Rebecca Naumann, Ann Dellinger. National Center for Injury Prevention and Control. European and U.S. surveys (2011). March 2013.
Quote: “More than two-thirds of U.S. adult drivers aged reported they had talked on their cell phone while driving at least once in the past 30 days. (In European countries), percentages ranged from 20 percent to 60 percent.”
Is Your Baby Safe on the Road?
American Baby and Safe Kids Worldwide. Survey of 2,396 female drivers with a child under age 2. January 2013.
Quote: “78% of (surveyed) moms talk on the phone while driving with their kids. … 26% text or check email. … Nearly 10% of new moms have been in a crash while driving with their baby — nearly three times higher than the rate among the general population.”
Pedestrian Safety Survey
Ketchum Global Research & Analytics for Liberty Mutual Insurance. Phone survey of 1,004 adults. June 2013.
Quote: “60 percent of pedestrians walk while texting, emailing, talking on the phone, or listening to music despite 70 percent considering those behaviors to be dangerous. … A 2011 report (found) 1,152 people were treated in hospital emergency rooms after being injured while walking and using a cell phone or some other electronic device.”
Observational Study of Cell Phone and Texting Use Among California Drivers 2012
Ewald & Wasserman for Safe Transportation Research and Education Center UC Berkeley. 5,664 vehicle observations from 129 sites. November 2012.
Quote: “The percentage of distracted driving by electronic devices observed increased to 6.2% in 2012 from 4.2% in 2011. … The age group of 16-24-year-olds had a significantly higher rate of distracted driving (11.4 percent) compared with older age groups.”
Teen Driver Distraction Study
University of Michigan Transportation Research Institute and Toyota Collaborative Safety Research Center. National phone survey of of 2,610 teen drivers and 2,934 parents. November 2012.
Quote: “Parents who engage in distracting behaviors more frequently have teens who engage in distracting behaviors. … Teens read or send text messages once a trip 26 times more often than their parents think they do.”
The Influence of Music on Mental Effort and Driving Performance
A. Ünal, L. Steg, K. Epstude. University of Groningen, The Netherlands. Driving simulations with loud music. September 2012
Quote: “Listening to music increased mental effort while driving (but) drivers who listened to music performed as well as the drivers who did not. … Mental effort might mediate the effect of music on driving performance.” (Read more about the driving study.)
Effects of Electronic Billboards on Driver Distraction
Tania Dukic, Christer Ahlstrom, etc. Swedish National Road and Transport Research Institute. (Published in the Traffic Injury Prevention journal.) Study of 41 volunteer drivers. October 2012.
Quote: “Drivers had a significantly longer dwell time, a greater number of fixations and longer maximum fixation duration when driving past an electronic billboard compared to other signs on the same road stretches. Whether the electronic billboards … constitute a traffic safety hazard cannot be answered conclusively based on the present data.”
Distracted driving Among Newly Licensed Teens
A. Goodwin, R. Foss, S. Harrell, N. O’Brien, UNC Highway Safety Research Center/AAA Foundation for Traffic Safety. Video recorders in family vehicles. March 2012.

B. Reimer, B. Mehler, Y. Wang, J.F. Coughlin, J.F. MIT field study. February 2012.
Quote: “Drivers’ awareness of vehicle surroundings is incrementally impacted by increases in cognitive demand (such as thinking about unrelated problems).” (article)
Two Hands Better Than One
S. Jamson, Institute for Transport Studies, University of Leeds (U.K.). Driving simulator tests of one-handed drivers. Funded by Esure. April 2012.
Quote: “(Driver) reaction times increased by 44 per cent when eating behind the wheel (22 percent while drinking). … Participants made the most corrections to their steering when talking on a mobile-device.”
High School Students Improve Motor Vehicle-related Health Behaviors
Centers for Disease Control: 2011 National Youth Risk Behavior Survey. 15,000 high school students surveyed in 43 states. 2011.
