Arthritis
Nearly half of people ages 65 and older are affected by arthritis. When arthritis affects a person's hands, painful or stiff fingers can make simple driving tasks like buckling a seat belt, turning a key, adjusting seats and mirrors, and steering more difficult.
Range Of Motion
By the time we reach 60, our range of motion can decrease by up to 25 percent. That loss of flexibility can make it harder to turn to check blind spots, merge or back up. It can also make reaching for and buckling a seatbelt difficult.
Eyesight
The most common vision problems experienced by older drivers include cataracts, macular degeneration and glaucoma.
