Wisconsin has issued an odd subclass of plates, which all use a common "Special" prefix then a suffix of some seemingly random letters. It is unknown what the significance of these letters is, if any. Each of these types correspond to a specific type of special vehicle registration, and many are quite rare.
This section will include the following plate types:
Special-UX plates have been confirmed since 1956. Special-UX plates are used for trucks and trailers with permanently mounted special equipment, qualifying for reduced-fee registrations. Only one pair of Special-UX plates is known to exist, not even being shown in the ALPCA archives except 1957. This type has been discontinued since 2004.

In 1980, special-UX plates gained weight class codes along with many other plate types. The weight classes were E to T, with E encompassing the E weight class and anything below that weight class.
Multiple D weight class plates from 1982 to 1990 have been found, and it is unknown how these plates were made as all plate guides from the time period state that all weight classes below 20,000 pounds used an EX code.
