Thanks for the replies.
I do have to retake my tests (I just moved to IL), so I've been brushing up with the IL study guide. I don't yet have hazmat but I need it for my new company- I guess it's just as well that I didn't get it before I moved here.
The local DMV did have a dedicated CDL holder's window with no need to take a number - it was kind of nice to have that little perk.
