(1999 Code, sec. 86-92(a))
(a) 
Except as may otherwise be provided by law and as specifically provided for in this division, it shall be unlawful for any person to drive or operate, or cause to be driven or operated, on any public street within the corporate limits of the city, any commercial motor vehicle, truck tractor, trailer or semi-trailer, or any combination of such vehicles, with or without load, contrary to any of the following limitations:
(1) 
No such vehicle or combination of vehicles shall have a greater weight than 20,000 pounds carried on any one axle, including all enforcement tolerances; or with tandem axle weight in excess of 34,000 pounds, including all enforcement tolerances; or with an overall gross weight on a group of two or more consecutive axles produced by application of the following formula:
W  =  500
(LN + 12N + 36)
(N - 1)
W
=
Overall gross weight on any group of two or more consecutive axles to the nearest 500 pounds.
L
=
Distance in feet between the extreme of any group of two or more consecutive axles.
N
=
Number of axles in group under consideration, except that two consecutive sets of tandem axles may carry a gross load of 34,000 pounds each, providing that the overall distance between the first and last axle of such consecutive sets of tandem axles is 36 feet or more, and provided that such overall gross weight may not exceed 80,000 pounds, including all enforcement tolerances.
(2) 
No such vehicle or combination of vehicles shall have a greater weight than 600 pounds per inch width of tire upon any wheel concentrated upon the surface of the city street and using high-pressure tires, and a greater weight than 650 pounds per inch of tire upon any wheel concentrated upon the surface of the highway and using low-pressure fires, and no wheel shall carry a load in excess of 8,000 pounds on high-pressure tires and 10,000 pounds on low- pressure tires, nor any axle load in excess of 16,000 pounds on high-pressure tires and 20,000 pounds on low-pressure tires.
(3) 
In this section, an axle load is defined as the total load transmitted to the road by all wheels whose centers may be included between the two parallel transverse planes 40 inches apart, extending across the full width of the vehicle. Tandem axle group is defined as two or more axles spaced 40 inches or more apart from center to center having at least one common point of weight suspension.
(b) 
No person shall load, or cause to be loaded, a vehicle for operation on the public streets of this city with the intent to violate the weight limitations in subsection (a) of this section. Intent to violate those limitations is presumed if the loaded vehicle exceeds the applicable gross vehicular weight limit by 15 percent or more. The provisions of this subsection do not apply to the loading or causing to be loaded of an agricultural or forestry commodity prior to the processing of the commodity.
(c) 
The provisions of this division shall not apply to:
(1) 
Any person operating or causing to be operated a motor vehicle under a valid and subsisting permit for the operation of overweight or oversize equipment issued by the city;
(2) 
Emergency vehicles operating in response to any emergency call; and

(1999 Code, sec. 86-92(b))
(a) 
Required.
A permit shall be required for the operation and/or movement over any public street of the city of any vehicle, when such vehicle cannot comply with one or more of the maximum weight load restrictions set forth in this division.
(b) 
Application.
Application for a permit shall be made to the chief of police or his duly authorized designee, and shall include the following:
(1) 
Name of the vehicle owner, with business address (if different from the vehicle operator).
(2) 
A descriptive statement of the kind, type and character of the goods and/or materials to be transported.
(3) 
An affidavit, duly sworn to before an officer authorized to administer oaths, showing the weight of such vehicle, the maximum load to be transported thereon, and the total gross weight for which the vehicle is to be permitted.
(4) 
A statement specifying the destination and time of the delivery of goods and/or materials.
Vehicles requiring the filing of a surety bond as specified in section 20.06.034 of this division must be received and on file in the office of the chief of police before a permit will be issued.
(c) 
Issuance; effect; display.
(1) 
The permit issued to the applicant shall show:
(A) 
The total gross weight for which the vehicle is registered.
(B) 
The specific route through the city which the vehicle is permitted to traverse.
(C) 
A descriptive statement of the kind, type and character of the goods and/or materials to be transported.
(D) 
A specific time period during which operation and/or movement of the vehicle is permitted.
(2) 
The permit and/or a copy shall be carried at all times in any such vehicle while such vehicle is upon the city streets. Any violation of any of the terms and/or conditions of the permit, as issued, shall render the permit void. The copy of the permit above required shall be admissible in evidence in any case in which the gross registered weight of such vehicle is an issue, and shall be prima facie evidence of the gross weight for which such vehicle is permitted. Such copy of the permit shall be displayed to any officer authorized to enforce this division, upon request by such officer. The issuance of a permit for an overweight movement shall not be a guarantee by the city that the streets can safely accommodate such movement, whether with or without permit, and [the permittee] shall be strictly liable for any damage such movement shall cause the streets or any of its structures or appurtenances.
(d) 
Fee.
It is recognized that the movement of such overweight vehicles is a privilege not accorded to every user of the city streets, and it is logical and proper that the fee to be charged for special transportation will be $50.00.
(e) 
Notice to property developers.
Prior to the development of any property within the city, the owners of such development shall be advised by the city staff that all overweight vehicles transporting ready-mix concrete are required to have a permit issued under this division.
(1999 Code, sec. 86-92(c))
The owner/operator of vehicles used exclusively to transport ready-mixed concrete, which is hereby defined as a perishable product, shall be required to obtain a permit from the chief of police, or his duly authorized designee, and such vehicles may be operated upon the public streets of this city with a tandem axle load not to exceed 44,000 pounds, a single axle load not to exceed 20,000 pounds, and a gross load not to exceed 64,000 pounds; provided that, where the vehicle is to be operated with a tandem axle load in excess of 34,000 pounds, the owner/operator of such vehicle shall first file with the city a surety bond in the principal sum as fixed by the city, which sum shall not be set at a greater amount than $15,000.00 for each vehicle. Such bond shall be conditioned that the owner of such vehicle will pay to the city, within the limit of such bond, all damages done to the city streets by reason of the operation of such vehicle with a tandem axle load in excess of 34,000 pounds. Such bond shall be subject to the approval of the city attorney's office. All bonds shall expire on August 31 of each year. Any vehicle weighing two-thirds or less of the above-noted limits shall not be required to be permitted.
(1999 Code, sec. 86-92(d))
Any police officer having reason to believe that the gross weight or axle load of a loaded motor vehicle is unlawful is authorized to cause such vehicle to be weighed by means of portable or stationary scales furnished or approved by the department of public safety, or cause the same to be weighed by any approved public weigher, and to require that such vehicle be driven to the nearest available scales for the purpose of weighing. If the gross weight of the vehicle exceeds the permitted gross weight, the police officer shall cite the operator/owner of such vehicle for being in violation of the provisions of this division; provided, however, that if such load consists of livestock or perishable merchandise, then such operator or owner shall be permitted to proceed with his vehicle to the nearest practical point in the direction of his destination where his load may be protected from damage or destruction if he is required to secure an additional permit before being allowed to proceed. It shall be conclusively presumed and deemed prima facie evidence that, where an operator or owner is apprehended and found to be carrying a greater gross load than that for which he is permitted, he has been carrying similar loads from the date of purchase of such permit.
