by amending section 722 (MCL 257.722), as amended by 2008 PA 579.
THE PEOPLE OF THE STATE OF MICHIGAN ENACT:
1 Sec. 722. (1) The maximum axle load shall not exceed the
2 number of pounds designated in the following provisions that
3 prescribe the distance between axles:
4 (a) If the axle spacing is 9 feet or more between axles, the
5 maximum axle load shall not exceed 18,000 pounds for vehicles
6 equipped with high pressure pneumatic or balloon tires.
7 (b) If the axle spacing is less than 9 feet between 2 axles
8 but more than 3-1/2 feet, the maximum axle load shall not exceed
9 13,000 pounds for high pressure pneumatic or balloon tires.
10 (c) If the axles are spaced less than 3-1/2 feet apart, the
11 maximum axle load shall not exceed 9,000 pounds per axle.
12 (d) Subdivisions (a), (b), and (c) shall be known as the
1 normal loading maximum.
2 (2) When normal loading is in effect, the state
3 transportation department, or a local authority with respect to
4 highways under its jurisdiction, may designate certain highways,
5 or sections of those highways, where bridges and road surfaces
6 are adequate for heavier loading, and revise a designation as
7 needed, on which the maximum tandem axle assembly loading shall
8 not exceed 16,000 pounds for any axle of the assembly, if there
9 is no other axle within 9 feet of any axle of the assembly.
10 (3) On a legal combination of vehicles, only 1 tandem axle
11 assembly shall be permitted on the designated highways at the
12 gross permissible weight of 16,000 pounds per axle, if there is
13 no other axle within 9 feet of any axle of the assembly, and if
14 no other tandem axle assembly in the combination of vehicles
15 exceeds a gross weight of 13,000 pounds per axle. On a
16 combination of truck tractor and semitrailer having not more than
17 5 axles, 2 consecutive tandem axle assemblies shall be permitted
18 on the designated highways at a gross permissible weight of
19 16,000 pounds per axle, if there is no other axle within 9 feet
20 of any axle of the assembly.
21 (4) Notwithstanding subsection (3), on a combination of
22 truck tractor and semitrailer having not more than 5 axles, 2
23 consecutive sets of tandem axles may carry a gross permissible
24 weight of not to exceed 17,000 pounds on any axle of the tandem
25 axles if there is no other axle within 9 feet of any axle of the
26 tandem axles and if the first and last axles of the consecutive
27 sets of tandem axles are not less than 36 feet apart and the
1 gross vehicle weight does not exceed 80,000 pounds to pick up and
2 deliver agricultural commodities between the national truck
3 network or special designated highways and any other highway.
4 This subsection is not subject to the maximum axle loads of
5 subsections (1), (2), and (3). For purposes of this subsection, a
6 "tandem axle" means 2 axles spaced more than 40 inches but not
7 more than 96 inches apart or 2 axles spaced more than 3-1/2 feet
8 but less than 9 feet apart. This subsection does not apply during
9 that period when reduced maximum loads are in effect pursuant to
10 under subsection (8).
11 (5) The exception to the loading maximums and gross vehicle
12 weight requirements of subsection (12) under subsection (8) for a
13 person hauling agricultural commodities applies only seasonal
14 reductions described under subsection (8) to the loading maximums
15 and gross vehicle weight requirement of subsection (12) do not
16 apply to a person hauling agricultural commodities if the person
17 who picks up or delivers the agricultural commodity either from a
18 farm or to a farm notifies the county road commission for roads
19 under its authority not less than 48 hours before the pickup or
20 delivery of the time and location of the pickup or delivery. The
21 county road commission shall issue a permit to the person and
22 charge a fee that does not exceed the administrative costs
23 incurred. The permit shall contain all of the following:
24 (a) The designated route or routes of travel for the load.
25 (b) The date and time period requested by the person who
26 picks up or delivers the agricultural commodities during which
27 the load may be delivered or picked up.
1 (c) A maximum speed limit of travel, if necessary.
2 (d) Any other specific conditions agreed to between the
3 parties.
4 (6) The exception to the loading maximums and gross vehicle
5 weight requirements of subsection (12) under subsection (8)
6 applies to public utility vehicles that are owned or operated by
7 public utilities under the jurisdiction of the Michigan public
8 service commission, or are subcontracted by public utilities
9 under the jurisdiction of the Michigan public service commission
10 to perform electrical emergency public utility work, only
11 seasonal reductions described under subsection (8) to the loading
12 maximums and gross vehicle weight requirements of subsection (12)
13 do not apply to public utility vehicles under the following
14 circumstances:
15 (a) For emergency public utility work on restricted roads,
16 as follows:
17 (i) If required by the county road commission, the public
18 utility or its subcontractor shall notify the county road
19 commission, as soon as practical, of the location of the
20 emergency public utility work and provide a statement that the
21 vehicles that were used to perform the emergency utility work may
22 have exceeded the loading maximums and gross vehicle weight
23 requirements of subsection (12) as reduced under subsection (8).
24 The notification may be made via facsimile or electronically.
25 (ii) The public utility vehicle travels to and from the site
26 of the emergency public utility work while on a restricted road
27 at a speed not greater than 35 miles per hour.
1 (b) For nonemergency public utility work on restricted
2 roads, as follows:
3 (i) If the county road commission requires, the public
4 utility or its subcontractor shall apply to the county road
5 commission annually for a seasonal truck permit for roads under
6 its authority before seasonal weight restrictions are effective.
7 The county road commission shall issue a seasonal truck permit
8 for each public utility vehicle or vehicle configuration the
9 public utility or subcontractor anticipates will be utilized for
10 nonemergency public utility work. The county road commission may
11 charge a fee for a seasonal truck permit that does not exceed the
12 administrative costs incurred for the permit. The seasonal truck
13 permit shall contain all of the following:
14 (A) The seasonal period requested by the public utility or
15 subcontractor during which the permit is valid.

11 subcontractor using a vehicle on a restricted road shall have a
12 copy of any notification provided to a county road commission in
13 the subcontractor's possession while performing the relevant
14 nonemergency work. Notwithstanding this subsection or an
15 agreement under this subsection, if the county road commission
16 determines that the condition of a particular road under its
17 jurisdiction makes it unusable, the county road commission may
18 deny access to all or any part of that road. The denial shall be
19 made and communicated via facsimile or electronically to the
20 public utility or its subcontractor within 24 hours after
21 receiving notification that the public utility or subcontractors
22 intends to perform nonemergency work that requires use of that
23 road. Any notification that is not disapproved within 24 hours

14 with a concrete base is reduced by 25% from the maximum axle load
15 as specified in this chapter, and the maximum axle loads
16 allowable on all other types of roads during these months are
17 reduced by 35% from the maximum axle loads as specified. The
18 maximum wheel load shall not exceed 525 pounds per inch of tire
19 width on concrete and concrete base or 450 pounds per inch of
20 tire width on all other roads during the period the seasonal road
21 restrictions are in effect. This Subject to subsection (5), this
22 subsection does not apply to vehicles transporting agricultural
23 commodities or, subject to subsection (6), public utility
24 vehicles on a highway, road, or street under the jurisdiction of
25 a local road agency. The state transportation department and each
26 local authority with highways and streets under its jurisdiction
27 to which the seasonal restrictions prescribed under this

16 alternate routes for which the permit may be issued. The
17 applicant may appeal to the state transportation commission or
18 the county road commission. These exemptions do not apply on
19 county roads in counties that have negotiated agreements with
20 milk haulers or haulers of other commodities during periods of
21 seasonal load limits before April 14, 1993. This subsection does
22 not limit the ability of these counties to continue to negotiate
23 such agreements.
24 (10) The state transportation department, or a local
25 authority with respect to highways under its jurisdiction, may
26 suspend the restrictions imposed by this section when and where
27 conditions of the highways or the public health, safety, and
1 welfare warrant suspension, and impose the restricted loading
2 requirements of this section on designated highways at any other
3 time that the conditions of the highway require.
4 (11) For the purpose of enforcing this act, the gross
5 vehicle weight of a single vehicle and load or a combination of
6 vehicles and loads shall be determined by weighing individual
7 axles or groups of axles, and the total weight on all the axles
8 shall be the gross vehicle weight. In addition, the gross axle
9 weight shall be determined by weighing individual axles or by
10 weighing a group of axles and dividing the gross weight of the
11 group of axles by the number of axles in the group. For purposes
12 of subsection (12), the overall gross weight on a group of 2 or
13 more axles shall be determined by weighing individual axles or
14 several axles, and the total weight of all the axles in the group
15 shall be the overall gross weight of the group.
16 (12) The loading maximum in this subsection applies to
17 interstate highways, and the state transportation department, or
18 a local authority with respect to highways under its
19 jurisdiction, may designate a highway, or a section of a highway,
20 for the operation of vehicles having a gross vehicle weight of
21 not more than 80,000 pounds that are subject to the following
22 load maximums:
23 (a) Twenty thousand pounds on any 1 axle, including all
24 enforcement tolerances.
25 (b) A tandem axle weight of 34,000 pounds, including all
26 enforcement tolerances.
27 (c) An overall gross weight on a group of 2 or more
1 consecutive axles equaling:
2 W = 500 /LN + 12N + 36\
3 \N-1 /
4 where W = overall gross weight on a group of 2 or more
5 consecutive axles to the nearest 500 pounds, L = distance in feet
6 between the extreme of a group of 2 or more consecutive axles,
7 and N = number of axles in the group under consideration; except
8 that 2 consecutive sets of tandem axles may carry a gross load of
9 34,000 pounds each if the first and last axles of the consecutive
10 sets of tandem axles are not less than 36 feet apart. The gross
11 vehicle weight shall not exceed 80,000 pounds including all
12 enforcement tolerances. Except for 5 axle truck tractor,
13 semitrailer combinations having 2 consecutive sets of tandem
14 axles, vehicles having a gross weight in excess of 80,000 pounds
15 or in excess of the vehicle gross weight determined by
16 application of the formula in this subsection are subject to the
17 maximum axle loads of subsections (1), (2), and (3). As used in
18 this subsection, "tandem axle weight" means the total weight
19 transmitted to the road by 2 or more consecutive axles, the
