You should have a conversation with the DMV.

I have been dealing with the same issues for a couple years now. My Dad is 83 and has diabetes which is really impacting his abilities. He was involved in a minor accident and apparently left the scene. The resulting police report forced him to retake the DMV test which he did not pass. Mom also recently got into an accident with similar results. I moved their Jeep into their garage and have the keys. It is not currently registered or insured - which I use as an excuse for now. Every couple weeks Dad says he is getting a locksmith to re-key the Jeep and that he is fine to drive. I have to remove the Jeep from their property (I do have POA) but that will cause a huge row for sure. However the risks are far too great and it is a source of real stress for me.

Like Scott we have care givers at the home as well. Can only afford a couple days a week and they use that opportunity to go places.
