Dear PD,
I noticed that you are in PA... There was an article in our paper that doctors in PA are mandated by law to report any condition that would impede driving. So if you are being seen by a doctor and have an alcohol problem, the doctor has to report this to the State. (That was the basis of the article: a guy got his licensed suspended as he was being treated for alcoholism.) I think all states should adopt this law....due to the elderly driving and others who should not be on the road. Doctors should be liable!
Now it's my FIL with AD and seizures. But I have since found out that most states have a form that anyone can fill out and send in to have a person re-examinated...anonymously. My FIL received a notice from the state that he needed to go to the DMV for re-examination for his license. He has no idea why he got this form. He went last week and they asked if he had his license with him... He answered yes, and they clipped the corner of it. He is suspended until he gets forms filled out from the doctor saying he can drive.
In his case, he not only has AD, but uncontrolled seizures. MIL says she hopes he'll be able "just to drive around town".... then proceeded to say how he drove thru a barricade as the street was blocked off for a parade! Comes home with a big dent on his truck... Luckily no one was hurt!
So, check on-line at the state web site. ... That's where I found the form, printed it off, filled it out and sent it in. I think you won't have as much of a problem due to your licensing laws.
FIL says he's going to drive anyway....but he hasn't! They pick up the papers from the doctor tomorrow (Mon) and he thinks he can go back to the DMV and have his license reinstated. Our law in this state says you have to be seizure free for 6 months. So unless the doctor lies....I don't think he'll be getting his license back anytime soon! Dr. also has to list all meds and why the patient is taking them.
FIL also has road rage....rams cars on the exit ramps, cuts cars off, gets lost, follows cars to their destination so he can "fight"....etc. etc.

MIL is in complete denial too! I don't get it!

MIL will even say they could lose everything if he hurts or kills someone.... then in the next breath says : she hopes he can drive around town!! Yeah, kill someone you know!
So check out your State's web site....There will be something about re-examination.... You have to be the parent now.... and yes, it s*cks!!! With AD there is no asking what they want to do or how they want to handle something.... You just have to do it! Then start on getting POA.
Prayers,
Choquis
