10  the maximum axle load shall not exceed the number of pounds

 

11  designated in the following provisions that prescribe the

 

12  distance between axles:

 

13        (a) If the axle spacing is 9 feet or more between axles, the

 

14  maximum axle load shall not exceed 18,000 20,000 pounds for

 

15  vehicles equipped with high pressure pneumatic or balloon tires.

 

16        (b) If the axle spacing is less than 9 feet between 2 axles

 

17  but more than 3-1/2 feet, the maximum axle load shall not exceed

 

18  13,000 20,000 pounds for high pressure pneumatic or balloon

 

19  tires.

 

20        (c) If the axles are spaced less than 3-1/2 feet apart, the

 

21  maximum axle load shall not exceed 9,000 pounds per axle.

 

22        (d) Subdivisions (a), (b), and (c) shall be known as the

 

23  normal loading maximum.

 

24        (2) When normal loading is in effect, the state

 

25  transportation department, or a local authority with respect to

 

26  highways under its jurisdiction, may designate certain highways,

 

27  or sections of those highways, where bridges and road surfaces

 

 1  are adequate for heavier loading, and revise a designation as

 

 2  needed, on which the maximum tandem axle assembly loading shall

 

 3  not exceed 16,000 pounds for any axle of the assembly, if there

 

 4  is no other axle within 9 feet of any axle of the assembly.

 

 5        (3) On a legal combination of vehicles, only 1 tandem axle

 

 6  assembly is permitted on the designated highways at the gross

 

 7  permissible weight of 16,000 pounds per axle, if there is no

 

 8  other axle within 9 feet of any axle of the assembly, and if no

 

 9  other tandem axle assembly in the combination of vehicles exceeds

 

10  a gross weight of 13,000 pounds per axle. On a combination of

 

11  truck tractor and semitrailer having not more than 5 axles, 2

 

12  consecutive tandem axle assemblies are permitted on the

 

13  designated highways at a gross permissible weight of 16,000

 

14  pounds per axle, if there is no other axle within 9 feet of any

 

15  axle of the assembly.

 

16        (4) Notwithstanding subsection (3), on a combination of

 

17  truck tractor and semitrailer having not more than 5 axles, 2

 

18  consecutive sets of tandem axles may carry a gross permissible

 

19  weight of not to exceed 17,000 20,000 pounds on any axle of the

 

20  tandem axles if there is no other axle within 9 feet of any axle

 

21  of the tandem axles and if the first and last axles of the

 

22  consecutive sets of tandem axles are not less than 36 feet apart

 

23  and the gross vehicle weight does not exceed 80,000 pounds to

 

24  pick up and deliver agricultural commodities between the national

 

25  truck network or special designated highways and any other

 

26  highway. This subsection is not subject to the maximum axle loads

 

27  of subsections (1), (2), and (3). For purposes of this

 

 1  subsection, a "tandem axle" means 2 axles spaced more than 40

 

 2  inches but not more than 96 inches apart or 2 axles spaced more

 

 3  than 3-1/2 feet but less than 9 feet apart. This subsection does

 

 4  not apply during that the period when reduced maximum loads are

 

 5  in effect under subsection (8).

 

 6        (5) The seasonal reductions described under subsection (8)

 

 7  to the loading maximums and gross vehicle weight requirement of

 

 8  subsection (12) do not apply to a person hauling agricultural

 

 9  commodities if the person who picks up or delivers the

 

10  agricultural commodity either from a farm or to a farm notifies

 

11  the county road commission for roads under its authority not less

 

12  than 48 hours before the pickup or delivery of the time and

 

13  location of the pickup or delivery. The county road commission

 

14  shall issue a permit to the person and charge a fee that does not

 

15  exceed the administrative costs incurred. The permit shall

 

16  contain all of the following:

 

17        (a) The designated route or routes of travel for the load.

 

18        (b) The date and time period requested by the person who

 

19  picks up or delivers the agricultural commodities during which

 

20  the load may be delivered or picked up.

 

21        (c) A maximum speed limit of travel, if necessary.

 

22        (d) Any other specific conditions agreed to between the

 

23  parties.

 

24        (6) The seasonal reductions described under subsection (8)

 

25  to the loading maximums and gross vehicle weight requirements of

 

26  subsection (12) do not apply to public utility vehicles under the

 

27  following circumstances:

 

 1        (a) For emergency public utility work on restricted roads,

 

 2  as follows:

 

 3        (i) If required by the county road commission, the public

 

 4  utility or its subcontractor shall notify the county road

 

 5  commission, as soon as practical, of the location of the

 

 6  emergency public utility work and provide a statement that the

 

 7  vehicles that were used to perform the emergency utility work may

 

 8  have exceeded the loading maximums and gross vehicle weight

 

 9  requirements of subsection (12) as reduced under subsection (8).

 

10  The notification may be made via facsimile or electronically.

 

11        (ii) The public utility vehicle travels to and from the site

 

12  of the emergency public utility work while on a restricted road

 

13  at a speed not greater than 35 miles per hour.

 

14        (b) For nonemergency public utility work on restricted

 

15  roads, as follows:

 

16        (i) If the county road commission requires, the public

 

17  utility or its subcontractor shall apply to the county road

 

18  commission annually for a seasonal truck permit for roads under

 

19  its authority before seasonal weight restrictions are effective.

 

20  The county road commission shall issue a seasonal truck permit

 

21  for each public utility vehicle or vehicle configuration the

 

22  public utility or subcontractor anticipates will be utilized for

 

23  nonemergency public utility work. The county road commission may

 

24  charge a fee for a seasonal truck permit that does not exceed the

 

25  administrative costs incurred for the permit. The seasonal truck

 

26  permit shall contain all of the following:

 

27        (A) The seasonal period requested by the public utility or

 

 1  subcontractor during which the permit is valid.

14  configuration shall display signage on the outside of the vehicle

 

15  to identify the vehicle as operating on behalf of the public

 

16  utility.

 

17        (ii) If the county road commission requires notification, the

 

18  county road commission shall provide a notification application

 

19  for the public utility or its subcontractor to use when

 

20  requesting access to operate on restricted roads and the public

 

21  utility or its subcontractor shall provide notification to the

 

22  county road commission, via facsimile or electronically, not

 

23  later than 24 hours before the time of the intended travel. A

 

24  subcontractor using a vehicle on a restricted road shall have a

 

25  copy of any notification provided to a county road commission in

 

26  the subcontractor's possession while performing the relevant

 

27  nonemergency work. Notwithstanding this subsection or an

 

 1  agreement under this subsection, if the county road commission

 

 2  determines that the condition of a particular road under its

 

 3  jurisdiction makes it unusable, the county road commission may

 

 4  deny access to all or any part of that road. The denial shall be

 

 5  made and communicated via facsimile or electronically to the

 

 6  public utility or its subcontractor within 24 hours after

 

 7  receiving notification that the public utility or subcontractors

 

 8  intends to perform nonemergency work that requires use of that

 

 9  road. Any notification that is not disapproved within 24 hours

 

10  after the notice is received by the county road commission is

 

11  considered approved. The notification application required under

18        (E) In the case of a subcontractor, the utility on whose

 

19  behalf the subcontractor is performing services.

 

20        (7) The normal size of tires shall be the rated size as

 

21  published by the manufacturers, and the maximum wheel load

 

22  permissible for any wheel shall not exceed 700 pounds per inch of

 

23  width of tire.

 

24        (8) Except as provided in this subsection and subsection

 

25  (9), during the months of March, April, and May in each year, the

 

26  maximum axle load allowable on concrete pavements or pavements

 

27  with a concrete base is reduced by 25% from the maximum axle load

 

 1  as specified in this chapter, and the maximum axle loads

 

 2  allowable on all other types of roads during these months are

 

 3  reduced by 35% from the maximum axle loads as specified. The

 

 4  maximum wheel load shall not exceed 525 pounds per inch of tire

 

 5  width on concrete and concrete base or 450 pounds per inch of

 

 6  tire width on all other roads during the period the seasonal road

 

 7  restrictions are in effect. Subject to subsection (5), this

 

 8  subsection does not apply to vehicles transporting agricultural

 

 9  commodities or, subject to subsection (6), public utility

 

10  vehicles on a highway, road, or street under the jurisdiction of

 

11  a local road agency. In addition, this subsection does not apply

 

12  to a vehicle delivering propane fuel to a residence if the

 

13  vehicle's propane tank is filled to not more than 50% of its

 

14  capacity and the vehicle is traveling at not more than 35 miles

 

15  per hour. The state transportation department and each local

 

16  authority with highways and streets under its jurisdiction to

 

17  which the seasonal restrictions prescribed under this subsection

 

18  apply shall post all of the following information on the homepage

 

19  of its website or, if a local authority does not have a website,

 

20  then on the website of a statewide road association of which it

 

21  is a member:

 

22        (a) The dates when the seasonal restrictions are in effect.

 

23        (b) The names of the highways and streets and portions of

 

24  highways and streets to which the seasonal restrictions apply.

 

25        (9) The state transportation department for roads under its

 

26  jurisdiction and a county road commission for roads under its

 

27  jurisdiction may grant exemptions from seasonal weight

 

 1  restrictions for milk on specified routes when requested in

 

 2  writing. Approval or denial of a request for an exemption shall

 

 3  be given by written notice to the applicant within 30 days after

 

 4  the date of submission of the application. If a request is

 

 5  denied, the written notice shall state the reason for denial and

 

 6  alternate routes for which the permit may be issued. The

 

 7  applicant may appeal to the state transportation commission or

 

 8  the county road commission. These exemptions do not apply on

 

 9  county roads in counties that have negotiated agreements with

 

10  milk haulers or haulers of other commodities during periods of

 

11  seasonal load limits before April 14, 1993. This subsection does

 

12  not limit the ability of these counties to continue to negotiate

 

13  such agreements.

 

14        (10) The state transportation department, or a local

 

15  authority with respect to highways under its jurisdiction, may

 

16  suspend the restrictions imposed by this section when and where

 

17  conditions of the highways or the public health, safety, and

 

18  welfare warrant suspension, and impose the restricted loading

 

19  requirements of this section on designated highways at any other

 

20  time that the conditions of the highway require.

 

21        (11) For the purpose of enforcing this act, the gross

 

22  vehicle weight of a single vehicle and load or a combination of

 

23  vehicles and loads shall be determined by weighing individual

 

24  axles or groups of axles, and the total weight on all the axles

 

25  shall be the gross vehicle weight. In addition, the gross axle

 

26  weight shall be determined by weighing individual axles or by

 

27  weighing a group of axles and dividing the gross weight of the

 

 1  group of axles by the number of axles in the group. For purposes

 

 2  of subsection (12), the overall gross weight on a group of 2 or

 

 3  more axles shall be determined by weighing individual axles or

 

 4  several axles, and the total weight of all the axles in the group

 

 5  shall be the overall gross weight of the group.

 

 6        (12) The loading maximum in this subsection applies to

 

 7  interstate highways, and the state transportation department, or

 

 8  a local authority with respect to highways under its

 

 9  jurisdiction, may designate a highway, or a section of a highway,

 

10  for the operation of vehicles having a gross vehicle weight of

 

11  not more than 80,000 pounds that are subject to the following

 

12  load maximums:

 

13        (a) Twenty thousand pounds on any 1 axle, including all

 

14  enforcement tolerances.

 

15        (b) A tandem axle weight of 34,000 pounds, including all

 

16  enforcement tolerances.

 

17        (c) An overall gross weight on a group of 2 or more

 

18  consecutive axles equaling:

 

 

19       W=500[(LN)/(N-1)+12N+36]

 

 

20        where W = overall gross weight on a group of 2 or more

 

21  consecutive axles to the nearest 500 pounds, L = distance in feet

 

22  between the extreme of a group of 2 or more consecutive axles,

 

23  and N = number of axles in the group under consideration; except

 

24  that 2 consecutive sets of tandem axles may carry a gross load of

 

25  34,000 pounds each if the first and last axles of the consecutive

 

26  sets of tandem axles are not less than 36 feet apart. The gross

 

 1  vehicle weight shall not exceed 80,000 pounds including all

 

 2  enforcement tolerances. Except for 5 axle truck tractor,

 

 3  semitrailer combinations having 2 consecutive sets of tandem

 

 4  axles, vehicles having a gross weight in excess of 80,000 pounds

 

 5  or in excess of the vehicle gross weight determined by

 

 6  application of the formula in this subsection are subject to the

 

 7  maximum axle loads of subsections (1), (2), and (3). As used in

 

 8  this subsection, "tandem axle weight" means the total weight

 

 9  transmitted to the road by 2 or more consecutive axles, the

 

10  centers of which may be included between parallel transverse

 

11  vertical planes spaced more than 40 inches but not more than 96

 

12  inches apart, extending across the full width of the vehicle.

 

13  Except as otherwise provided in this section, vehicles

 

14  transporting agricultural commodities shall have weight load

 

15  maximums as set forth in this subsection.

 

16        (13) The axle loading maximums under subsections (1), (2),

 

17  (3), and (4) are increased by 10% for vehicles transporting

 

18  agricultural commodities or raw timber, excluding farm equipment

 

19  and fuel, from the place of harvest or farm storage to the first

 

20  point of delivery on a road in this state. However, the axle

 

21  loading maximums as increased under this subsection do not alter

 

22  the gross vehicle weight restrictions set forth in this act. This

 

23  subsection does not apply to either of the following:

 

24        (a) A vehicle utilizing an interstate highway.

 

25        (b) A vehicle utilizing a road that is subject to seasonal

 

26  weight restrictions under subsection (8) during the time that the

 

27  seasonal weight restrictions are in effect.

 

 1        (14) Notwithstanding any other provision of this section,

 

 2  the total gross weight of a vehicle shall not exceed 120,000

 

 3  pounds.
