(b) The maximum gross weight on a group of three consecutive axles, where the distance between centers of foremost and rearmost axles of any axle group is seven feet or eight feet, is 34,000 pounds, except for vehicles manufactured before August 1, 1991. Notwithstanding any lesser weight shown in the axle weight limits table, for vehicles manufactured before August 1, 1991:
(1) the maximum gross weight on a group of three consecutive axles, where the distance between centers of foremost and rearmost axles of any axle group is seven feet, is 37,000 pounds; and
(2) the maximum gross weight on a group of three consecutive axles, where the distance between centers of foremost and rearmost axles of any axle group is eight feet, is 38,500 pounds.

Gross weights in excess of 80,000 pounds require an overweight permit under this chapter, unless otherwise allowed under section169.826.
(e) Notwithstanding any lesser weight shown in the axle weight limits table, but subject to the restrictions on gross vehicle weights in subdivision 2, clauses (1) and (2), two consecutive sets of tandem axles may carry a gross load of 34,000 pounds each and a combined gross load of 68,000 pounds provided the overall distance between the first and last axles of the consecutive sets of tandem axles is 36 feet or more.
Subd. 2.Gross vehicle weight of all axles.
The gross vehicle weight of all axles of a vehicle or combination of vehicles must not exceed:
(1) 80,000 pounds for any vehicle or combination of vehicles on all streets and highways, unless posted at a lower axle weight under section169.87, subdivision 1; and

Subd. 3.Weight limit credits; idle- and emissions-reduction technology; natural gas vehicles.
(a) Notwithstanding the maximum weight provisions of this section, the maximum gross vehicle weight limits and the axle weight limits for any motor vehicle subject to sections169.80to169.88that is equipped with idle-reduction technology or emissions-reduction technology are increased by the amount of weight necessary to compensate for the weight of the idle-reduction technology or emissions-reduction technology, not to exceed 550 pounds.
(b) Notwithstanding the maximum weight provisions of this section, the maximum gross vehicle weight limits and the axle weight limits for any motor vehicle that is a natural gas vehicle and subject to sections169.80to169.88are increased by the amount of weight calculated as provided under United States Code, title 23, section 127(s), not to exceed 2,000 pounds.
