Wis. Stat. § 343.51

(1) Any person who qualifies for registration plates of a special design under s. 341.14 (1), (1a), (1m), or (1q) or any other person with a disability that limits or impairs the ability to walk may request from the department a special identification card that will entitle any motor vehicle parked by, or under the direction of, the person, or a motor vehicle operated by or on behalf of the organization when used to transport such a person, to parking privileges under s. 346.50 (2), (2a), and (3). The department shall issue the card at a fee to be determined by the department, upon submission by the applicant, if the applicant is an individual rather than an organization, of a statement from a physician licensed to practice medicine in any state, from an advanced practice registered nurse licensed to practice nursing in any state, from a public health nurse certified or licensed to practice in any state, from a physician assistant licensed or certified to practice in any state, from a podiatrist licensed to practice in any state, from a chiropractor licensed to practice chiropractic in any state, from a physical therapist licensed to practice in any state, or from a Christian Science practitioner residing in this state and listed in the Christian Science journal that the person is a person with a disability that limits or impairs the ability to walk. The statement shall state whether the disability is permanent or temporary and, if temporary, the opinion of the physician, advanced practice registered nurse, public health nurse, physician assistant, podiatrist, chiropractor, physical therapist, or practitioner as to the duration of the disability. The department shall issue the card upon application by an organization on a form prescribed by the department if the department believes that the organization meets the requirements under this subsection.
