THE PEOPLE OF THE STATE OF MICHIGAN ENACT:
1 Sec. 722. (1) Except as otherwise provided in this section,
2 the maximum axle load shall not exceed the number of pounds
3 designated in the following provisions that prescribe the distance
4 between axles:
5 (a) If the axle spacing is 9 feet or more between axles, the
6 maximum axle load shall not exceed 18,000 pounds for vehicles
7 equipped with high pressure pneumatic or balloon tires.
8 (b) If the axle spacing is less than 9 feet between 2 axles
9 but more than 3-1/2 feet, the maximum axle load shall not exceed
10 13,000 pounds for high pressure pneumatic or balloon tires.
1 (c) If the axles are spaced less than 3-1/2 feet apart, the
2 maximum axle load shall not exceed 9,000 pounds per axle.
3 (d) Subdivisions (a), (b), and (c) shall be known as the
4 normal loading maximum.
5 (2) When normal loading is in effect, the state transportation
6 department, or a local authority with respect to highways under its
7 jurisdiction, may designate certain highways, or sections of those
8 highways, where bridges and road surfaces are adequate for heavier
9 loading, and revise a designation as needed, on which the maximum
10 tandem axle assembly loading shall not exceed 16,000 pounds for any
11 axle of the assembly, if there is no other axle within 9 feet of
12 any axle of the assembly.
13 (3) On a legal A
combination of vehicles ,
only may operate on
14 designated highways with not more than 1 tandem axle assembly is
15 permitted on the designated highways at the having a gross
16 permissible weight of
16,000 pounds per axle, if there is no other
17 axle within 9 feet of any axle of the assembly. ,
and if no other
18 tandem axle assembly in the combination of vehicles exceeds a gross
19 weight of 13,000 pounds per axle. On a combination of truck tractor
20 and semitrailer having not more than 5 axles, 2 consecutive tandem
21 axle assemblies are permitted may operate on the designated
22 highways at a gross permissible weight of 16,000 pounds per axle,
23 if there is no other axle within 9 feet of any axle of the either
24 assembly.
25 (4) Notwithstanding subsection (3), on a combination of truck
26 tractor and semitrailer having not more than 5 axles, 2 consecutive
27 sets of tandem axles may carry a gross permissible weight of not to
1 exceed 17,000 pounds on any axle of the tandem axles if there is no
2 other axle within 9 feet of any axle of the tandem axles and if the
3 first and last axles of the consecutive sets of tandem axles are
4 not less than 36 feet apart and the gross vehicle weight does not
5 exceed 80,000 pounds to pick up and deliver agricultural
6 commodities between the national truck network or special
7 designated highways and any other highway. This subsection is not
8 subject to the maximum axle loads of subsections (1), (2), and (3).
9 For purposes of this subsection, a "tandem axle" means 2 axles
10 spaced more than 40 inches but not more than 96 inches apart or 2

27 (11) For the purpose of enforcing this act, the gross vehicle
1 weight of a single vehicle and load or a combination of vehicles
2 and loads shall be determined by weighing individual axles or
3 groups of axles, and the total weight on all the axles shall be the
4 gross vehicle weight. In addition, the gross axle weight shall be
5 determined by weighing individual axles or by weighing a group of
6 axles and dividing the gross weight of the group of axles by the
7 number of axles in the group. For purposes of subsection (12), the
8 overall gross weight on a group of 2 or more axles shall be
9 determined by weighing individual axles or several axles, and the
10 total weight of all the axles in the group shall be the overall
11 gross weight of the group.
12 (12) The loading maximum in this subsection applies to
13 interstate highways, and the state transportation department, or a
14 local authority with respect to highways under its jurisdiction,
15 may designate a highway, or a section of a highway, for the
16 operation of vehicles having a gross vehicle weight of not more
17 than 80,000 pounds that are subject to the following load maximums:
18 (a) Twenty thousand pounds on any 1 axle, including all
19 enforcement tolerances.
20 (b) A tandem axle weight of 34,000 pounds, including all
21 enforcement tolerances.
22 (c) An overall gross weight on a group of 2 or more
23 consecutive axles equaling:
|
24 |
W=500[(LN)/(N-1)+12N+36] |
25 where W = overall gross weight on a group of 2 or more
26 consecutive axles to the nearest 500 pounds, L = distance in feet
1 between the extreme of a group of 2 or more consecutive axles, and
2 N = number of axles in the group under consideration; except that 2
3 consecutive sets of tandem axles may carry a gross load of 34,000
4 pounds each if the first and last axles of the consecutive sets of
5 tandem axles are not less than 36 feet apart. The gross vehicle
6 weight shall not exceed 80,000 pounds including all enforcement
7 tolerances. Except for 5 axle truck tractor, semitrailer
8 combinations having 2 consecutive sets of tandem axles, vehicles
9 having a gross weight in excess of 80,000 pounds or in excess of
10 the vehicle gross weight determined by application of the formula
11 in this subsection are subject to the maximum axle loads of
12 subsections (1), (2), and (3). As used in this subsection, "tandem
13 axle weight" means the total weight transmitted to the road by 2 or
14 more consecutive axles, the centers of which may be included
15 between parallel transverse vertical planes spaced more than 40
16 inches but not more than 96 inches apart, extending across the full
17 width of the vehicle. Except as otherwise provided in this section,
18 vehicles transporting agricultural commodities shall have weight
19 load maximums as set forth in this subsection.
20 (13) The axle loading maximums under subsections (1), (2),
21 (3), and (4) are increased by 10% for vehicles transporting
22 agricultural commodities or raw timber, excluding farm equipment
23 and fuel, from the place of harvest or farm storage to the first
24 point of delivery on a road in this state. However, the axle
25 loading maximums as increased under this subsection do not alter
26 the gross vehicle weight restrictions set forth in this act. This
27 subsection does not apply to either of the following:
1 (a) A vehicle utilizing an interstate highway.
2 (b) A vehicle utilizing a road that is subject to seasonal
3 weight restrictions under subsection (8) during the time that the
4 seasonal weight restrictions are in effect.
5 (14) Notwithstanding any other provision of this section, a
6 vehicle that has a gross weight of 80,000 pounds or less and that
7 is operated by an engine that is fueled wholly or partially by
8 compressed or liquefied natural gas may exceed the axle loading
9 maximums under subsections (1), (2), (3), and (4) and the weight
10 load maximums under subsection (12) by an amount equal to the
11 difference between the weight of the vehicle attributable to the
12 natural gas tank and fueling system carried by that vehicle and the
13 weight of a comparable diesel tank and fueling system. The amount
14 by which a vehicle described in this subsection may exceed the axle
15 loading maximums under subsections (1), (2), (3), and (4) and the
16 weight load maximums under subsection (12) shall not exceed 2,000
