A bill to amend 1949 PA 300, entitled
"Michigan vehicle code,"
by amending section 722 (MCL 257.722), as amended by 2012 PA 522.
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.
11 (c) If the axles are spaced less than 3-1/2 feet apart, the
1 maximum axle load shall not exceed 9,000 pounds per axle.
2 (d) Subdivisions (a), (b), and (c) shall be known as the
3 normal loading maximum.
4 (2) When normal loading is in effect, the state transportation
5 department, or a local authority with respect to highways under its
6 jurisdiction, may designate certain highways, or sections of those
7 highways, where bridges and road surfaces are adequate for heavier
8 loading, and revise a designation as needed, on which the maximum
9 tandem axle assembly loading shall not exceed 16,000 pounds for any
10 axle of the assembly, if there is no other axle within 9 feet of
11 any axle of the assembly.
12 (3) On a legal combination of vehicles, only 1 tandem axle
13 assembly is permitted on the designated highways at the gross
14 permissible weight of 16,000 pounds per axle, if there is no other
15 axle within 9 feet of any axle of the assembly, and if no other
16 tandem axle assembly in the combination of vehicles exceeds a gross
17 weight of 13,000 pounds per axle. On a combination of truck tractor
18 and semitrailer having not more than 5 axles, 2 consecutive tandem
19 axle assemblies are permitted on the designated highways at a gross
20 permissible weight of 16,000 pounds per axle, if there is no other
21 axle within 9 feet of any axle of the assembly.
22 (4) Notwithstanding subsection (3), on a combination of truck
23 tractor and semitrailer having not more than 5 axles, 2 consecutive
24 sets of tandem axles may carry a gross permissible weight of not to
25 exceed 17,000 pounds on any axle of the tandem axles if there is no
26 other axle within 9 feet of any axle of the tandem axles and if the
27 first and last axles of the consecutive sets of tandem axles are
1 not less than 36 feet apart and the gross vehicle weight does not
2 exceed 80,000 pounds to pick up and deliver agricultural
3 commodities between the national truck network or special
4 designated highways and any other highway. This subsection is not
5 subject to the maximum axle loads of subsections (1), (2), and (3).
6 For purposes of this subsection, a "tandem axle" means 2 axles
7 spaced more than 40 inches but not more than 96 inches apart or 2
8 axles spaced more than 3-1/2 feet but less than 9 feet apart. This
9 subsection does not apply during that period when reduced maximum
10 loads are in effect under subsection (8).
11 (5) The seasonal reductions described under subsection (8) to
12 the loading maximums and gross vehicle weight requirement of
13 subsection (12) do not apply to a person hauling agricultural
14 commodities if the person who picks up or delivers the agricultural
15 commodity either from a farm or to a farm notifies the county road
16 commission for roads under its authority not less than 48 hours
17 before the pickup or delivery of the time and location of the
18 pickup or delivery. The county road commission shall issue a permit
19 to the person and charge a fee that does not exceed the
20 administrative costs incurred. The permit shall contain all of the
21 following:
22 (a) The designated route or routes of travel for the load.
23 (b) The date and time period requested by the person who picks
24 up or delivers the agricultural commodities during which the load
25 may be delivered or picked up.
26 (c) A maximum speed limit of travel, if necessary.
27 (d) Any other specific conditions agreed to between the
1 parties.
2 (6) The seasonal reductions described under subsection (8) to
3 the loading maximums and gross vehicle weight requirements of
4 subsection (12) do not apply to public utility vehicles under the
5 following circumstances:
6 (a) For emergency public utility work on restricted roads, as
7 follows:
8 (i) If required by the county road commission, the public
9 utility or its subcontractor shall notify the county road
10 commission, as soon as practical, of the location of the emergency
11 public utility work and provide a statement that the vehicles that
12 were used to perform the emergency utility work may have exceeded
13 the loading maximums and gross vehicle weight requirements of
14 subsection (12) as reduced under subsection (8). The notification
15 may be made via facsimile or electronically.
16 (ii) The public utility vehicle travels to and from the site
17 of the emergency public utility work while on a restricted road at

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