Driver Medical Review Practices Across the United States

There were 38.4 million licensed older drivers in 2014—a 31% increase from 10 years earlier (2005). Furthermore, older drivers as a percentage of all licensed drivers increased from 15% in 2005 to 18% in 2014 (National Center for Statistics and Analysis, 2016). As the driving population continues to age, medical conditions and associated impairments affecting driving abilities will become more prevalent, and State driver licensing agencies are likely to see driver medical review become an even more prominent part of their activities. A previous NHTSA report, Strategies for Medical Advisory Boards and Licensing Review, highlighted similarities and differences in driver medical review practices across the United States (Lococo & Staplin, 2005). This present three-volume study builds upon the previous report by documenting strengths and limitations of the various approaches developed by the States to evaluate medical fitness to drive. Particular areas of interest included the methods States used to identify those most at risk, subsequent licensing actions, and the effects of these actions on individuals’ licenses.
