A. O. Ferdinand, N. Menachemi, University of Alabama at Birmingham. Fatality Analysis Reporting System analysis. August 2014.
Quote: “Texting-while-driving bans were most effective for reducing traffic-related fatalities among young individuals (but) handheld bans appear to be most effective for adults.” Secondary enforcement laws did not result in “significant reductions in traffic fatalities.”

L.J. Blincoe, T.R. Miller, E. Zaloshnja, B.A. Lawrence. National Highway Traffic Safety Administration. Data study. May 2014.
Quote: “Crashes involving a distracted driver … cost the nation $46 billion in 2010, an average cost of $148 for every person in the U.S. Including lost quality of life, these crashes were responsible for $129 billion of the overall societal harm caused by motor vehicle crashes.”
Social Norms and Risk Perception: Predictors of Distracted Driving Behavior Among Novice Adolescent Drivers
P. Carter, C. Bingham, J. Zakrajsek … University of Michigan School of Medicine. Nationwide phone survey of 403 adolescents and their parents. May 2014.

J. Ehsani, C. Bingham, E. Ionides, D. Childers, Shriver National Institute of Child Health and Human Development. Study of crash rates and trends for drivers in Michigan, 2005–2012. May 2014.
Quote: “We hypothesized that the introduction of the texting restriction for all drivers would be followed by a reduction in crashes of all severities. (But) statistically significant increases in crash rates and trends in fatal/disabling injury crashes and nondisabling injury crashes and decreases in possible injury/PDO crashes were observed. … The relationship between texting restrictions and crashes is complex.”
Distracted Driving and Risk of Crashes Among Novice and Experienced Drivers
S. Klauer, F. Guo, B. Simons-Morton, Virginia Tech Transportation Institute. In-vehicle tracking of new and veteran drivers. January 2014.

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

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.
