@willow5 Yes, a physician has a duty to report an incapable and currently licensed driver if they assess one as no longer capable. Or, the licensing bureau or insurer will, if they learn of the apparent/suspected incapacity, send a letter to the driver stating that they require a letter of assessment from a qualified physician. Happened to me when I informed the licensing bureau of my atrial fibrillation. It was the usual question on the five-year renweal questionnaire about any health changes, and as an honest person, I dutifully responded truthfully.
