IN is mutually-exclusive. You cannot have a license plate and an OHV registration on the same vehicle. Fortunately, it's pretty easy to put a plate on a "converted" dirt bike here. I run IN plates instead of the OHV stickers and I can still get into the two state-owned riding areas if I want to pay the gate fee.
The goofy thing on that IL law is that you would have to have the sticker to ride on your neighbor's property. That's ridiculous and pitiful. It's what you get when you elect a bunch of crazy left-wingers, a loss of freedom and liberty. But I'm sure it's justified "to protect our children".
