I went through this issue with my Father; I took care of him for two and a half years at home. He THOUGHT he was o.k. to drive, but some of his physical conditions precluded that; so, I made myself available to him at all times for shopping, banking, haircuts, an afternoon out to lunch or dinner; took him for rides, which he really enjoyed; when he driver's license renewal came, I consulted his gerontologist, made an appointment, and the doctor put him through an extensive neurologic and medical exam, shook his head and said..."no more driving"; he asked me if I wanted him (the doctor) to tell Dad; I said "no"; so, after the appointment, Dad and I went to lunch, a drive, some shopping, and then home; the renewal was on his desk, never opened (I have it to this day; Dad passed in 1998); and I sat down and discussed the issue with Dad (he so enjoyed driving and I knew I was taking something precious away, but it had to be done), he listened to me; took my hand and said: "Honey, whatever you say, I know you know best." It broke my heart. Soon after, he went to Hospice and passed away.
His safety and the safety of others was on my mind even though I knew it would hurt to take that license. I am 70 and I know how I appreciate the privilege of my license. I can only hope I am well enough to drive for some years to come but if I became a danger to myself and others....the license has to go. I only hope someone would be kind enough to help me with all my needs.
God bless you, Dad.....
