Driving Impairment Among Older Adults

Older drivers may have age-related and medical conditions that affect their driving performance.

More than 90% of car crashes are caused by human error. In older adults, age-related changes of decreased vision, cognitive decline, slowed reaction time, and decreased grip strength increase the risk of common driving errors, including straying from driving lanes, failing to observe speed limits, and overlooking traffic signs.

The risk of dying in a car crash is 2.5 times higher for drivers aged 75 to 79 years and 5 times higher for those aged 80 years or older compared with younger drivers.
