Please note: I no longer reside in Wisconsin or actively collect Wisconsin plates, and this page has not been revised since 2013.
Obviously, the "extremes" have gotten a little more extreme since then!
All the pictures on this particular page are of currently-used or fairly current license plates photographed in use on actual vehicles. If you have a photo of something in active use either higher or lower than what you see here, submissions are very much welcome! In addition, observers are welcome to submit their highest spottings to the Wisconsin Highs page of LicensePlates.cc.
The idea for this page was stolen wholesale from Royce's Alaskan License Plate site. Wisconsin often replaces older passenger car and light truck plates on a gradual and haphazard basis; so tracking the oldest extent of that is a bit of a challenge in itself.
