My FIL is a 90 year old suffering from far-advanced diabetes. He cannot feel his lower legs, has lost his toenails and has small sores most of the time as he fails to listen to the doctors instructions. His eyesight was so poor that he failed the drivers vision test. His blood sugar is often out of control. He is taking many medications. He drives over the speed limit. He has driven in a ditch several times, damaging his car once. He was sent notification that his drivers license was revoked by the local DOT about 8 months ago. His eldest son sent the necessary paperwork to the DOT to begin the driving testing process. The local hospital also sent in paperwork declaring he should no longer drive. His doctors have also sent in paperwork showing he is no longer physically safe to drive. Apparently, his car insurer has not yet been notified as his insurance was renewed and a new 2018 auto registration sticker was sent to him. He continues to drive. His daughter (she lives 40 minutes away) is available to drive him with only an overnight's notice. She already takes him to Doctors appts and shopping. She cooks for him and cleans his home. We all know that one reason he demands driving himself is that he purchases all kinds of sweets, which no one else will buy for him. He refuses to live with his retired, eldest son, my husband and me, who have an eldercare suite for him. We all want him to retain his dignity, yet we all feel he is a danger to himself and others while driving. No one has the courage to take away his keys as we all know he will become very angry, possibly causing more acute health and psychological issues. He has always been fiercely independent, but this has become a test of his will. Any suggestions?
