Changes with Aging
“Driving provides older people freedom, independence, and key social interactions with their community that many people take for granted in their youth. But the privilege of driving is based on the ability to safely operate a motor vehicle. Many factors can diminish the driving performance of older adults, including age-related changes in reaction time, and visual, cognitive, and/or muscle disorders that become more common with age. Drugs are commonly used to treat disorders in older people, and some classes of drugs can be sedating and impair driving performance.” (https://www.merckmanuals.com/)
