What's the punishment for driving a de-registered car without plates?

I've always wanted to drive one of these, and while I can only drive it inside the scrapyard where it’s located, it got me wondering: if I were to drive a vehicle that's not roadworthy, is it true that a $200 fine could apply? And would simply saying 'yes officer, I’ll drive it back to the yard' be enough to avoid further trouble?
