(1)    A minor under 16 years of age shall not be employed or permitted to work at any street trade unless the minor’s employer first obtains from the department or a permit officer a street trade permit and the minor first obtains an identification card, both issued in accordance with this section.

   (2)   If upon investigation, the department determines that there are practical difficulties or unnecessary hardships in carrying out sub. (1), the department may by general or special order make reasonable exceptions or modifications with due regard for the life, health, safety and welfare of minors employed in street trades. The investigation and orders shall be made as provided under s. 103.005. These orders are subject to review as provided in ch. 227.

   (3)   The form and requisites of street trade permits shall be the same as those specified for permits authorizing the employment of minors under s. 103.73, except as provided in sub. (3m) and except that the permits may be issued on special street trade permit forms, in a form determined by the department. Each minor for whom a street trade permit is issued shall be provided by the department or the permit officer issuing the permit with a street trade identification card, in a form determined by the department. The minor shall carry the identification card while engaged in street trade employment and may not transfer it to any other person.

   (3m)   

      (a)    In addition to the information required for a street trade permit under sub. (3), a street trade permit obtained by a house-to-house employer shall contain the minor’s permanent home address and social security number.

      (b)    A house-to-house employer shall have a copy of the street trade permit issued for the minor stamped or endorsed by the clerk of any municipality where the minor conducts a street trade from house to house.

      (c)    This subsection does not apply to employment of a minor by a newspaper publisher or in a fund-raising sale for a nonprofit organization, a public school, a private school, or a tribal school.

   (4)   In relation to employment in street trades a permit issued under this section has the same force and effect as a permit issued under ss. 103.64 to 103.82; and the failure to obtain a permit when required under this section subjects the employer to the same penalties and liabilities as failure to obtain a permit when required under ss. 103.64 to 103.82.

   (5)   This section does not apply to employment of a minor in a fund-raising sale for a nonprofit organization, a public school, a private school, or a tribal school.
