Assessing older drivers for physical and cognitive impairment.

For older drivers, the automobile is often a vital link in maintaining independence, acquiring goods, and socializing. However, physical or cognitive impairments linked to aging or disease may imperil the driver, passengers, and others on the road. For drivers with multiple medical conditions, physicians can reduce the risk for a crash by identifying and treating illnesses that can impair driving ability. If the conditions cannot be treated, consider modifying the driving environment to reduce the risk, rather than taking away driving privileges. If the risk is unacceptable, seek alternate modes of transportation.
