Not driving was the most difficult adjustment for my husband with LBD. Even after both PCP & Neurologist told him it wasn’t safe to drive he kept wanting to. It’s been an ongoing issue that comes up periodically. He was removed from our insurance policy so that is the approach I use to remind him. And in general he does not have access to vehicle keys. Only my vehicle had current registration & he has no access to it. We also have an “agreement” about him not driving. At one point he became belligerent & drove away in his pick-up truck. I’d given him the keys to check inside the cab for a misplaced jacket. Up to that time he had been very compliant with our agreement. You just can’t trust a dementia, even if you trust the person. I told him if he drove out of the driveway I would call law enforcement. He did, so I did. Fortunately we are a small town & he is not unknown to them. They have a file with some of his bizarre late-night calls. They found him & followed him home. The Deputy gave him a very respectful lecture about no insurance & no registration & made him give me the vehicle keys. I have since moved that truck to off-site storage that I pay for. The other truck - also not currently registered - has misplaced keys. He left them lying around & I removed them. That truck he just liked to start up & let run to keep the engine in good condition. But he also kept wanting to hook up a battery charger to it 🙄. Believe me it would be hard to find a more difficult situation than an ex-auto mechanic who is an ex-truck driver & former CDL holder. Driving was his life & his passion. It’s taken a lot of different approaches, plenty of time, etc.
