Wis. Stat. § 125.175: Issuance of operators’ permits.

(1) Subject to sub. (4), the division shall issue an operator’s permit to any applicant who is qualified under s. 125.04 (5). Operators’ permits may not be required other than for the purpose of complying with ss. 125.32 (2) and 125.68 (2) or s. 125.06 (3g). Operators’ permits may be issued only upon written application.

(2) Operators’ permits are valid in all municipalities in this state.

(3) The division shall establish a fee for issuance or renewal of an operator’s permit and shall determine whether the permit shall be valid for one or 2 years.

(4)

(a) The division may not issue an operator’s permit unless the applicant satisfies the criteria for issuance of an operator’s license specified in s. 125.17 (6) (a). In applying these criteria to an applicant who holds or previously held an operator’s permit or an operator’s license, the division shall treat as synonymous operators’ permits and operators’ licenses.

(b) The division may not require applicants for operators’ permits to undergo training in addition to that specified in s. 125.17 (6) (a) but may require applicants to purchase at cost materials that deal with relevant subjects not covered in the course under s. 125.17 (6) (a).
