Vanity plates are a great way to test a state's limits on freedom of expression, which makes them good kindling for lawsuits. The latest license litigation comes from Michigan, where the American Civil Liberties Union has brought suit on behalf of a plaintiff against the state for rejecting the plate "WAR SUX."
From the current issue of Car and Driver comes an interesting piece on personalized license plates, and how they are reviewed for suitability. In particular, it focuses on the process exemplified by the Word Committee, which is a board created by the Virginia Department of Motor Vehicles tasked with approving custom plates.
Kansas is revamping the way it issues vanity plates, and it means a lot of residents are going to lose their 'duplicate' personalized plates. They're not really duplicates, though: Unlike most states, Kansas allows people in different counties to have the same alphanumeric combination, so while the tags might appear to be copies, they are registered in different counties and that technically makes them different plates.
