The Intersection of Aging and Disability: Impacts on Driving Safety

In 2021, there were 55.8 million people—17 percent of the total U.S. population—who were 65 and older. As more older adults are staying behind the wheel for longer, it is important to bring attention to the intersection of aging and disability and its impact on driving safety. ChORUS can help you understand how potential age-related changes and disabilities affect driving, which is crucial for promoting road safety and supporting older adults in maintaining their independence. In this blog, we provide insight on how physical and cognitive changes throughout the aging process can affect older adults’ ability to drive safely. 

Physical Changes 

Aging often brings physical changes that can influence driving abilities. Decreased muscle strength and joint flexibility can make it harder to perform essential driving maneuvers, such as turning the steering wheel or pressing the brake pedal. Slower reaction times can reduce an older adult's ability to respond quickly to sudden changes in traffic. 

Conditions such as cataracts, glaucoma, and macular degeneration can reduce visual acuity and peripheral vision, making it difficult to read road signs and detect hazards. Hearing loss can prevent drivers from hearing important sounds like sirens and horns, which are critical for safe driving.

Cognitive Changes

Cognitive functions, including memory, attention, and decision-making, often decline with age. Cognitive impairments, such as those caused by Alzheimer's disease or other dementias, can make it challenging for older adults to process information quickly and accurately, increasing the risk of crashes.

New Health Conditions and Medications

Many older adults manage chronic health conditions like arthritis, diabetes, and cardiovascular disease, which can affect physical and cognitive abilities. Additionally, the medications used to treat these conditions can have side effects, such as drowsiness or dizziness, further impacting driving safety.

The Prospect of Disability in Later Life

Living longer means an increased likelihood of developing a disability. Disabilities can range from mobility impairments, sensory and cognitive limitations, or anything stemming from the age-related changes listed above.
For older adults, driving often represents independence and autonomy. Losing the ability to drive could impact their daily lives and mental well-being, but through proper accommodation older adults can stay active in their communities. 

It is important to create an environment that accommodates the needs of older adults with disabilities. This includes promoting accessible public transportation options, encouraging the use of ride-sharing services, and supporting community programs that provide transportation assistance. By embracing these accommodations, we can help older adults maintain their independence and continue to lead active, fulfilling lives.
