A follow-on naturalistic study was conducted of teen drivers ages 16 - 19 involved in vehicle crashes between August 2013 and April 2015. There were 538 crashes during this interval, supplementing the original report's 1,691 teen driver crashes. Distraction-related, teen driver crashes due to cell phone use appear to be much more prevalent than is reflected in official government statistics.
In this study, we conducted a large-scale comprehensive examination of naturalistic data from thousands of actual crashes involving teenage drivers. The data allowed us to examine behaviors and potential contributing factors in the seconds leading up to the collision, and provided information not available inpolice reports.
