I don't know of any cases yet in Oklahoma with persons connected on one side or the other of the November, 2007 state law,
Oklahoma Statute, but it'd be interesting to read about any circumstances. Note the statue says repro tags can be used if they are stamped REPLACEMENT TAG.
I only wish other states would follow suit to put these sellers of 'novelty' items in jeopardy. I've seen a number of Chevelle reproduction tags from trimtags.com and, for the most part, are like phony window stickers and build sheets, no too hard to spot.
