Vehicle scale operators; scale installation and testing
Wis. Stat. § 98.16
in effect(1) Definitions. In this section “vehicle scale” means a commercial scale that is designed to weigh loaded or unloaded highway, farm or industrial vehicles, except that it does not include a scale that is operated exclusively by this state.
(2) License for operator.
(am) Except as provided in par. (dm), no person may operate a vehicle scale without an annual license from the department. A separate license is required for each scale. A license is not transferable between persons or scales. A license expires on March 31 annually.
(bm) The department shall provide a license application form for persons applying for a license. The form shall require all of the following:
1. The applicant’s correct legal name and business address and any trade name under which the applicant proposes to operate the vehicle scale.
2. A description of the nature and location of the vehicle scale.
3. Other information reasonably required by the department for licensing purposes.
(cm) A license application shall be accompanied by all of the following fees and surcharges:
1. A license fee in the amount specified by the department by rule promulgated under sub. (4).
2. A license fee surcharge, if the department determines that within one year prior to submitting the license application the applicant operated a vehicle scale without a license as required by par. (am). The license fee surcharge is $200, except that the department may establish a different surcharge by rule promulgated under sub. (4). The department may not issue a license under this subsection to an operator if the operator has failed to pay a license fee surcharge assessed against the operator. Payment of the license fee surcharge does not relieve the applicant of any other civil or criminal liability for the operation of a vehicle scale without a license but shall not constitute evidence of violation of a law.
(dm) Paragraph (am) does not apply to a person who operates a vehicle scale only as an employee of a person who is required to hold a license to operate the scale under this subsection.
(2m) Permit for scale installation or construction; variance.
(a) No person may install or relocate a vehicle scale without a permit from the department. The department shall provide a permit application form for a person applying for a permit under this paragraph. An application for a permit under this paragraph shall be accompanied by a nonrefundable permit application fee in an amount established by the department by rule promulgated under sub. (4).
(b) A person who installs or relocates a vehicle scale shall comply with construction, operation, and maintenance standards and procedures established by the department by rule under sub. (4), except that the department may grant a variance from a construction standard if the department determines that the variance is justified by special circumstances. The department may impose conditions on the variance, including alternative construction standards, if the department determines the conditions are necessary. The department shall provide a variance application form for a person applying for a variance under this paragraph. An application for a variance under this paragraph shall be accompanied by a nonrefundable variance application fee in an amount established by the department by rule promulgated under sub. (4).
(3m) Annual testing.
(a) The owner or operator of a scale with a weighing capacity of 5,000 pounds or more used for the commercial weighing of commodities shall cause the scales to be tested and inspected at least annually for accuracy by a person licensed under s. 98.18 (1).
(b) A person conducting a test under par. (a) shall do all of the following:
1. Conduct the test and prepare a test report, according to rules promulgated by the department under sub. (4).
2. Provide a copy of the test report to the operator of the vehicle scale and, if required by rules promulgated by the department under sub. (4), to other persons.
(c) An operator of a vehicle scale shall file with the department a copy of each test report prepared regarding the vehicle scale not more than 15 days after the operator receives the test report. If an operator fails to file a report as required in this paragraph, the department may assess a testing surcharge against the operator. The department may not issue a license under sub. (2) to an operator if the operator has failed to pay a testing surcharge assessed against the operator. If an operator fails to pay a testing surcharge assessed against the operator within 120 days after the department assessed the surcharge, the department may revoke the operator’s license to operate the vehicle scale for which the operator has been assessed the surcharge.
(d) If a test under this subsection shows that a vehicle scale is inaccurate, the scale may not be used until the inaccuracy is corrected and the scale is determined to be accurate by a subsequent test under this subsection.
(e) No person may falsify a test, test result, or test report under this subsection.
(f) This section does not apply to a railway scale used exclusively for the weighing of commodities on railroad track vehicles.
(4) Rules. The department shall promulgate rules to regulate the construction, operation, testing, and maintenance of vehicle scales, including a rule specifying the amount of the fee under sub. (2) (cm) 1. The department may promulgate rules to adjust fees and surcharges under subs. (2) (cm) 2. and (2m) (a) and (b) and to impose a testing surcharge upon a vehicle scale operator if the operator fails to file a vehicle scale test report as required by a rule promulgated by the department under this subsection.
