In KY that would get your registration revoked and you’d soon know it. Something like a warning letter at 30 days with active plate and vin not covered, 60 days registration revoked. Not sure if cops will show up, they weren’t wanting to do actual work was issue when law was being debated. But it will cause you trouble for sure as I dropped a truck I wasn’t using one time and didn’t scurrying the plate to the clerk. When I restarted it caused a penalty premium to be added to the policy because the database showed I had an active plate without covered for a period.
