Back in 2007, Michigan got new license plates. The Secretary of State's Office said that if you had the blue Great Lakes plate, even in good legible condition you had to get rid of it for the new blue on white plate or the new Spectacular Peninsulas plate, but you could keep your 15 year old, worn out, hard to read Auto Capital of the World or Great Lakes Splendor plates. What SHOULD have been done was to pass a law that ALL Michigan plates be changed every five years from when they are purchased. Reason for this is that the reflectorization on the license plates is only lasts for five years.
