This paragraph does not apply to the national system of interstate and defense highways, except for that portion of USH 51 between Wausau and STH 78 and that portion of STH 78 between USH 51 and the I 90/94 interchange near Portage upon their federal designation as I 39.
348.15(3)(c)
(c) The gross weight imposed on the highway by any group of 2 or more consecutive axles of a vehicle or combination of vehicles may not exceed the maximum gross weights in the following table for each of the respective distances between axles and the respective numbers of axles of a group: [See Figure 348.15 (3) (c) following]
-
See PDF for table 
348.15(3)(d)
(d) Notwithstanding
par. (c), 2 consecutive sets of tandem axles may impose on the highway a gross load of 34,000 pounds each if the overall distance between the first and last axles of such consecutive sets of tandem axles is 36 feet or more.
348.15(3)(e)
(e) Notwithstanding
pars. (a),
(b) and
(c), in the case of a vehicle or combination of vehicles transporting exclusively livestock, the gross weight imposed on the highway by the wheels of any one axle or axle group may exceed the applicable weight limitation specified in
pars. (a),
(b) and
(c) by 15% if the gross weight of the vehicle or combination of vehicles does not exceed the maximum gross weight specified for that vehicle or combination of vehicles under
par. (c). This paragraph does not apply to the national system of interstate and defense highways, except for that portion of USH 51 between Wausau and STH 78 and that portion of STH 78 between USH 51 and the I 90/94 interchange near Portage upon their federal designation as I 39.
348.15(4)
(4) Notwithstanding the possibility of increased weight on a particular wheel or axle or group of axles due to practical operating problems, including, but not limited to, accumulation of snow, ice, mud or dirt, the use of tire chains or minor shifting of load, the maximum weights set forth in
sub. (3) include absolutely all weights allowable.
348.15(5)
(5) For enforcement of weight limitations specified by this chapter the gross weight, measured in pounds, imposed on the highway by any wheel or any one axle or by any group of 2 or more axles shall be determined by weighing the vehicles and load, either by single draft or multiple draft weighing on certified stationary scales or on portable scales in good working order which are tested in comparison to certified stationary scales within 90 days immediately prior to any weighing operation by the department of agriculture, trade and consumer protection or other authorized testing agencies for accuracy to within standard accepted tolerances. The weighing operation shall be performed in accordance with and under conditions accepted as good weighing technique and practice. In multiple draft weighing the sum of the weight of respective components shall be used to establish the weight of a combination of the components. It is recognized that the weight, determined in accordance with methods prescribed in this chapter, includes all statutory weights and represents the momentary load force or reaction imposed on the scale at the time of weighing. Such weights include any variation due to the following factors:
348.15(5)(a)
(a) Positioning or tilt of the vehicle on the scale platform and adjacent bearing surface;
348.15(5)(b)
(b) Momentary position of axle centers with respect to wheel bearings and vehicle body;
348.15(5)(c)
(c) Temporary distribution of loading on the wheel or axle; and
348.15(5)(d)
(d) Miscellaneous variable factors of spring flexure, shackle friction, clutch engagement, brake pressure, tire compression and other variable factors.
348.15(5m)
(5m) The distances between axles and between the foremost and rearmost of a group of axles shall be measured between axle centers to the nearest even foot, and when a fraction is exactly one-half foot, the nearest larger whole number shall be used.
348.15(5r)
(5r) Irrespective of
sub. (5), in determining overweight under
sub. (3) the results of weighing by means of either portable scales or certified stationary scales shall be admissible as evidence. In all cases where a vehicle is weighed on a certified stationary scale, axles less than 6 feet apart shall be weighed as one unit.
348.15(6)
(6) At any state weighing scale where a vehicle is found overloaded, the driver may request its reweighing at the same scale. Upon reweighing the state officials shall supply the tabulated weight ticket to the driver. All weight tickets for any vehicle shall be supplied to the court in case the matter goes to trial.
348.15(8)
(8) Unless the department provides otherwise by rule, any axle of a vehicle or combination of vehicles which does not impose on the highway at least 8% of the gross weight of the vehicle or combination of vehicles may not be counted as an axle for the purposes of
sub. (3) (c).
348.15 Annotation
If a tractor-trailer combination is too long and too wide for a scale, multiple weighing of the separate wheel groups is permissible. An overload permit is to be disregarded if the total weight exceeds that specified in the permit. State v. Trailer Service, Inc.

Traffic officers may weigh vehicles and require removal of excess load. 348.19(1)(a)(a) Any traffic officer having reason to believe that the gross weight of a vehicle is unlawful or in excess of the gross weight for which the vehicle is registered may require the operator of such vehicle to stop and submit the vehicle and any load it may be carrying to a weighing by means of either portable or certified stationary scales and may require that such vehicle be driven to the nearest usable portable or certified stationary scale except as provided in
par. (b).
348.19(1)(b)
(b) Any other provision of the statutes notwithstanding, a vehicle transporting peeled or unpeeled forest products cut crosswise shall not be required to proceed to a scale more than one mile from the point of apprehension if the estimated gross weight of the vehicle does not exceed the lawful limit. The gross weight of the vehicle shall be estimated by multiplying the average length of the load by the average height of the load in feet and then multiplying by the average weight per square foot of load measurement and adding this computed weight to the empty weight of the vehicle. The average weights per square foot of load measurement to be used in computing the estimated load weight are given in the following table: [See Figure 348.19 (1) (b) following]
-
See PDF for table 348.19(2)(a)(a) Except as provided in
par. (b), whenever after a weighing of a vehicle and load as provided in
sub. (1) a traffic officer determines that the weight exceeds the limitations imposed by
s. 348.15,
348.16 or
348.17 (3) or
(4) or any limitations posted as provided in
s. 348.17 (1), the operator of such vehicle shall not proceed (except to drive to such place as directed by the traffic officer for the purpose of reloading or unloading) until such portion of the load has been reloaded or unloaded as may be necessary to reduce the weight of the vehicle and load to comply with the limitations imposed by
s. 348.15,
348.16 or
348.17 (3) or
(4) and any limitations posted as provided in
s. 348.17 (1). All material so reloaded or unloaded shall be reloaded or unloaded and cared for by and at the risk of the owner or operator of the vehicle.

Policy in prosecuting weight violations. 348.20(1)
(1) It is declared to be the public policy of the state that prosecutions for overweight violations shall in every instance where practicable be instituted against the person holding the authority, certificates, licenses or permits evidencing operating privileges from the department which may be the proper object of cancellation or revocation proceedings. In instances where a combination of tractor and trailer or semitrailer is used, the person standing in the relationship of principal or employer to the driver of the tractor portion of the vehicle combination is liable for violation of
ss. 348.15 to
348.17 along with the owner holding authority, certificates, licenses or permits from the state. It is a violation of
ss. 348.15 to
348.17 for the owner or any other person employing or otherwise directing the operator of the vehicle to require or permit the operation of such vehicle upon a highway contrary to
ss. 348.15 to
348.17. This section shall not apply to individuals, partnerships, limited liability companies or corporations whose principal business is leasing, for compensation, vehicles including trailers and semitrailers, but such prosecutions shall be instituted against the lessee of the vehicle.
348.20(2)
(2) The operator of a vehicle, as agent of the person holding authority, certificate, license or permit from the state or as agent of the owner of the tractor portion of a vehicle combination of tractor and trailer or semitrailer, shall accept service of a summons on behalf of such person or owner.

348.21(2)(a)(a) Any person who violates
s. 348.17 (2) or
348.19 (3) may be required to forfeit not less than $50 nor more than $100 upon the first conviction and, upon the 2nd or each subsequent conviction within a 12-month period, may be required to forfeit not less than $100 nor more than $200.
348.21(2)(b)
(b) If the load on any wheel, axle or group of axles does not exceed the weight prescribed in
s. 348.15 (3) or
348.16 or in a declaration issued under
s. 348.175 by more than 2,000 pounds and if such excess can be reloaded within the normal load carrying areas, on any other wheel, axle or axles, so that all wheels and axles are then within the statutory limits, the operator may reload as provided in this paragraph. A total of 2,000 pounds per vehicle or combination of vehicles may be reloaded under this subsection. If reloading is accomplished and all axles or group of axles are within the legal limits, no forfeiture may be imposed. A vehicle or combination of vehicles under this subsection which is not reloaded may continue to be operated upon the highway, but a forfeiture of $50 shall be imposed for failure to reload. This forfeiture shall be paid upon the basis of the citation issued by the official to the court named in the citation. Failure to pay shall subject the operator to the penalty in
par. (a) or
