Many age-related health conditions may impair safe driving ability, such as those affecting vision, cognition, neck flexibility. Though older drivers are in fewer crashes than their younger counterparts, such health conditions may cause increased frailty in this population, which means those who drive are more likely to be injured in the case of a crash. In addition, older drivers are more susceptible to impairment by alcohol, medications, cannabis and other drugs due to delayed metabolism and co-morbidities. The LongROAD study aims to explore the roles of medical, behavioral, social, technological, and environmental factors in safe driving among older adults. The study enrolled 2990 older drivers in sites in five states (Ann Arbor, MI; Baltimore, MD; Cooperstown, NY; Denver, CO; and San Diego, CA) from July 2015 through March 2017. LongROAD collects self-reported and objectively-measured health, functioning, and driving behaviors, objective driving data (from a device collecting global positioning, accelerometer measurements, etc.), medical record information, medication history, and state motor vehicle driving records. This presentation will report on early findings, based on data collected at baseline and one-year post enrollment.
