['Cell phone use while driving restricts peripheral awareness and impairs reaction time. This study assessed the 3-year prevalence of cell phone use (CPU) of drivers and characteristics associated with its use in six cities across Texas, 2011-2013.', 'CPU and driver characteristics were observed among motor vehicles (n\xa0=\xa01280) stopped at major intersections in medical and academic campuses. A multivariable logistic regression model described the association between driver characteristics and CPU.', 'The overall prevalence of any CPU was 18.7%. Any type of CPU and talking tended to decline, while texting seemed to increase from 2011 to 2013. CPU was more likely among female drivers (OR\xa0=\xa01.63; 95% CI\xa0=\xa01.21, 2.20), drivers <\xa025\xa0years of age (OR\xa0=\xa04.12; 95% CI\xa0=\xa02.29, 7.39), and drivers without passengers (OR\xa0=\xa04.40; 95% CI\xa0=\xa02.82, 6.88).'] Does prevalence and correlate of cell phone use among Texas drivers?
