H Plates Illinois
License plates from the late 1910s and early 1920s will often be narrow and longer than license plates from recent years, while plates in the 1940s will be shorter and wider. Youll notice that if you find a license plate from a government vehicle, theyll be in a traditional Illinois license plate shape, but only feature initials. When you register your vehicle with the Illinois Secretary of State (SOS), you can choose from a variety of different license plates available. The standard Illinois license plate has a blue and white background with an image of Lincoln and dark red lettering.
