My mother has difficulty walking and uses a cane. I worry about her falling in the parking lot, or having to walk any distance. She doesn't drive, but my father does. Your mother may qualify for a Handicapped Placard, which she can use with anyone who is driving her. My father refuses to stop driving even though his family is concerned about his ability to drive safely.
Statistics show that older drivers have fewer accidents than any other age group.
But this is misleading. When actual hours on the road are taken into consideration, older drivers have the second highest accident rate, second only to teenage drivers. In addition, they are more often injured when involved in an accident. But turning in the car keys represents such a loss of independence that many seniors continue drive. If the answer is yes to any of these questions and you're concerned, ask his doctor to make a referral for a Drivers Evaluation Test.
