We examine the relationship between cell phone use and traffi c accidents using a unique measure of cell phone coverage. The distance from an antenna tower accurately predicts whether or not an area has cellular coverage according to provider coverage maps in 2016. Cellular coverage between 2001 and 2011 is proxied for using the the distance between a road segment and the nearest antenna tower....

Our research examined the effects of hands-free cell phone conversations on simulated driving. We found that driving performance of both younger and older adults was influenced by cell phone conversations. Compared with single-task (i.e., driving-only) conditions, when drivers used cell phones their reactions were 18% slower, their following distance was 12% greater, and they took 17% longer to...
