CT DMV has recently changed their law enforcement computer system and it has caused me some strange problems this year.
I received a mailed notice from DMV last Fall that the insurance on my Z had lapsed briefly during the summer of 2021. That wasn't true ~ I've had continuous coverage on it since it came back into my possession in 2008. There was no lapse of coverage, ever, not even thru the winters. The notice warned me that I either had to pay a $200 fine or prove that I'd had continuous coverage, or I would be prohibited from registering (or updating) any vehicles.
I took the notice to my insurance broker and he promised to provide DMV with proof that I had never lapsed, and assured me everything would be fine.
It wasn't.
Last week I tried to register a new vehicle at DMV and was told the prohibition was still in place and they wanted the $200 fine, which I refused to pay. I visited my insurance broker (2d time) and complained that they hadn't notified CT DMV of my coverage as they had promised. They assured me they would do it immediately and I left before I hurt anyone. I made (yet another) DMV appointment for today.
At today's 3d DMV visit, they told me the prohibition was STILL in effect until I paid them the $200 fine, or I couldn't register (or renew) anything. I returned to my insurance broker a third time, struggling to behave myself. They proved to me they had notified DMV twice of my continuous coverage, and arranged to notify them the 3rd time.
I called DMV in Wethersfield and spoke with the Insurance Compliance unit (only a 22 minute wait on hold). This is what I learned, and what you might experience.
The new DMV computer system does not recognize "hyphens" in any VIN number, nor does it recognize any VIN which doesn't fit the current 17-digit format. Therefor, when my insurance company was sending notices of my continuous coverage and describing my vehicle by the 11-digit hyphenated VIN (HLS30-), the new DMV computer had no record of that number. Instead it was identifying my Z with the made-up 17-digit "VIN" of "CTUNKNOWN(plus my plate number)" and "1". Therefor, regardless how many notifications my Insurance company sent them, the new computer simply isn't programmed to recognize my actual VIN.
This is still being worked out (I still cannot register or renew any vehicles and I refuse to pay a $200 extortion fee for something which wasn't my fault), but you should be aware: because all of our Zs have "short" VIN numbers which contain a hyphen, this might also happen to you.
This should be a simple computer re-programming fix, but we all know what has happened to our beloved state in recent years.
More as it develops.
Looks nice Frank T., even if it's above your pay grade. LOL. 
It's been a Veteran plate since 2008 and renewed on-time each year. It's still on the car and (like the insurance) has never lapsed.
