You are correct, but your statement about "common sense" is false. Many states allow for just such a report in order for the state to begin an investigation in to an unsafe driver. "Common sense" would say that it's in the state's best interest to investigate reports from family members about unsafe elderly drivers. Illinois is in the minority in that it only allows a report from a police officer.
Thank you, you can also get a licensed physician to report it, but of course the state only investigates, and it's 60/40 whether my mother would pass an investigation or not, I think she might well pass.
I am not sure what a driving investigation entails, but 12 months ago her physician certified she is rational and can make her own decisions, though she has short term memory problems. But these situations tent to deteriorate at different speeds.
I thought the forum rules were about Illinois only law, not other states. Is there a valid point to talking about other states?
My wife was driving in Thailand since she was 16 but didn't get a license till she was 32. People stack merchandise 8 feet high on scooters. We could also discuss Thai driving rules if the forum regulars want to. Vietnam driving is even crazier, in Cambodia my "taxi" driver sat in the middle between two passengers in the front so he could jam in more people and drive us all 150 km to Siem Reap. I didn't think he could brake like that, at least he put the native passengers in the front seat.
Suffice it to say off hand I don't know what the rules are in other states, if I needed to know I would research it.
But I am not attacking you, only using your post to point out the obvious, and thanks for pointing out Illinois law.
