I am not sure there, but I know in other parts of the country, the Farm plates would make it MORE likely that you would be checked. I know a guy here in Indiana that is a farmer, and at any "farm type auction" (land, equipment, livestock. etc) the "Tax Police" were there dipping ever diesel truck on the property. There have been a few nailed this way, in pick-up and larger trucks with RED fuel, in IN, it is something like a $10k fine and could have some jail time. These were "farm trucks" but being used on the public roads, (I understand they were parked somewhere, but they were on at the "home" address of the vehicle, so they had to be driven to where they were on public roads.) Also, if I remember correctly, even thought the fine was levied, they were not allowed to move the trucks until all the RED fuel was removed, or they had to be towed from their location. I know in IN, they do not play.
