 3  a vehicle on a restricted road shall have a copy of any

 

 4  notification provided to a county road commission in the

 

 5  subcontractor's possession while performing the relevant

 

 6  nonemergency work. Notwithstanding this subsection or an agreement

 

 7  under this subsection, if the county road commission determines

 

 8  that the condition of a particular road under its jurisdiction

 

 9  makes it unusable, the county road commission may deny access to

 

10  all or any part of that road. The denial shall be made and

 

11  communicated via facsimile or electronically to the public utility

 

12  or its subcontractor within 24 hours after receiving notification

 

13  that the public utility or subcontractors intends to perform

 

14  nonemergency work that requires use of that road. Any notification

 

15  that is not disapproved within 24 hours after the notice is

 

16  received by the county road commission is considered approved. The

 

17  notification application required under this subparagraph may

 

18  include all of the following information:

14  negotiated agreements with milk haulers or haulers of other

 

15  commodities during periods of seasonal load limits before April 14,

 

16  1993. This subsection does not limit the ability of these counties

 

17  to continue to negotiate such agreements.

 

18        (10) The state transportation department, or a local authority

 

19  with respect to highways under its jurisdiction, may suspend the

 

20  restrictions imposed by this section when and where conditions of

 

21  the highways or the public health, safety, and welfare warrant

 

22  suspension, and impose the restricted loading requirements of this

 

23  section on designated highways at any other time that the

 

24  conditions of the highway require.

 

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

 

26  weight of a single vehicle and load or a combination of vehicles

 

27  and loads shall be determined by weighing individual axles or


 1  groups of axles, and the total weight on all the axles shall be the

 

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

 

 3  determined by weighing individual axles or by weighing a group of

 

 4  axles and dividing the gross weight of the group of axles by the

 

 5  number of axles in the group. For purposes of subsection (12), the

 

 6  overall gross weight on a group of 2 or more axles shall be

 

 7  determined by weighing individual axles or several axles, and the

 

 8  total weight of all the axles in the group shall be the overall

 

 9  gross weight of the group.

 

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

 

11  interstate highways, and the state transportation department, or a

 

12  local authority with respect to highways under its jurisdiction,

 

13  may designate a highway, or a section of a highway, for the

 

14  operation of vehicles having a gross vehicle weight of not more

 

15  than 80,000 pounds that are subject to the following load maximums:

 

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

 

17  enforcement tolerances.

 

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

 

19  enforcement tolerances.

 

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

 

21  consecutive axles equaling:

 

 

22

      W=500[(LN)/(N-1)+12N+36]

 

 

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

 

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

 

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

 

26  N = number of axles in the group under consideration; except that 2

 


 1  consecutive sets of tandem axles may carry a gross load of 34,000

 

 2  pounds each if the first and last axles of the consecutive sets of

 

 3  tandem axles are not less than 36 feet apart. The gross vehicle

 

 4  weight shall not exceed 80,000 pounds including all enforcement

 

 5  tolerances. Except for 5 axle truck tractor, semitrailer

 

 6  combinations having 2 consecutive sets of tandem axles, vehicles

 

 7  having a gross weight in excess of 80,000 pounds or in excess of

 

 8  the vehicle gross weight determined by application of the formula

 

 9  in this subsection are subject to the maximum axle loads of

 

10  subsections (1), (2), and (3). As used in this subsection, "tandem

 

11  axle weight" means the total weight transmitted to the road by 2 or

 

12  more consecutive axles, the centers of which may be included

 

13  between parallel transverse vertical planes spaced more than 40

 

14  inches but not more than 96 inches apart, extending across the full

 

15  width of the vehicle. Except as otherwise provided in this section,

 

16  vehicles transporting agricultural commodities shall have weight

 

17  load maximums as set forth in this subsection.

 

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

 

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

 

20  agricultural commodities or raw timber, excluding farm equipment

 

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

 

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

 

23  loading maximums as increased under this subsection do not alter

 

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

 

25  subsection does not apply to either of the following:

 

26        (a) A vehicle utilizing an interstate highway.

 

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


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

 

 2  seasonal weight restrictions are in effect.

 

 3        (14) Notwithstanding any other provision of this section, the

 

 4  total gross weight of a vehicle shall not exceed 80,000 pounds.
