(b) "Class `A' highway" includes all state trunk highways and connecting highways and those county trunk highways, town highways and city and village streets, or portions thereof, which have not been designated as class "B" highways pursuant to
s. 349.15.
348.15(3)
(3) Subject to any modifications made by a 1st class city under
s. 349.15 (3), no person, without a permit, may operate on a class "A" highway any vehicle or combination of vehicles unless the vehicle or combination of vehicles complies with the following weight limitations:
348.15(3)(a)
(a) The gross weight imposed on the highway by any one wheel or multiple wheels supporting one end of an axle may not exceed 11,000 pounds.
348.15(3)(b)
(b) The gross weight imposed on the highway by the wheels of any one axle may not exceed 20,000 pounds. In addition, the gross weight imposed on the highway by the wheels of the steering axle of a truck tractor may not exceed 13,000 pounds unless the manufacturer's rated capacity of the axle and the tires is sufficient to carry the weight, but not to exceed 20,000 pounds.
348.15(3)(bg)
(bg) In the case of a vehicle or combination of vehicles transporting exclusively milk from the point of production to the primary market and the return of dairy supplies and dairy products from such primary market to the farm, the gross weight imposed on the highway by the wheels of any one axle may not exceed 21,000 pounds or, for 2 axles 8 or less feet apart, 37,000 pounds or, for groups of 3 or more consecutive axles more than 9 feet apart, a weight of 2,000 pounds more than is shown in

-
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)(a)(a) 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
Where a tractor-trailer combination was too long and too wide for the scale, multiple weighing of the separate wheel groups is permissible. An overload permit is to be disregarded where the total weight exceeded that specified in the permit. State v. Trailer Service, Inc. 61 W (2d) 400, 212 NW (2d) 683.
