The permit fee is fifteen dollars ($15.00) for a single trip permit not to exceed ninety-six (96) continuous hours. The permit fee is fifty dollars ($50.00) for any ninety (90) continuous days. If a truck hauling forest products, sugar beets, gravel, livestock or agricultural products exceeds the legal weight limitations, the truck shall be allowed to unload at its point of destination in this state if the point of destination is within one (1) mile of the truck's location when the illegal weight limitation was determined, unless an immediate threat to public safety exists. No penalty for the first violation shall be imposed, but any subsequent violation shall be subject to the penalty provisions of W.S. 31-18-805.
(c) In special circumstances of individual movements of vehicles hauling single, multiple or readily divisible items which cannot be readily or safely dismantled or divided or which cannot be transported safely or without damage when dismantled or divided, the director or his authorized representative may upon application and good cause shown issue a permit in writing effective for a single trip by each permit authorizing the applicant to operate or move a vehicle or combination of vehicles of a width, height, length or weight of vehicle or load, exceeding the maximum specified in or authorized under W.S. 31-18-802.
(d) For movements of a vehicle without load, or meeting indivisible load requirements, or a trailer carrying a recreational boat that exceeds any maximum dimension or weight authorized under W.S. 31-18-802, the director or his authorized representative may upon application issue a permit in writing effective for an extended period of time, not to exceed one (1) year, authorizing the movement of the vehicle, provided that the size does not exceed seventy-five (75) feet in length for a single vehicle and twelve (12) feet in width or fifteen (15) feet in height for a single vehicle or combination of vehicles.

A copy of the permit shall be carried with the vehicle. The fee for such a permit shall not exceed two hundred fifty dollars ($250.00). Notwithstanding subsections (e) through (t) of this section, no additional permit requirements shall be imposed upon the commercial movement of such vehicles if such vehicles comply with W.S. 31-18-802(a)(i)(A). The permit fee for an overweight vehicle is as prescribed in subsection (g) of this section. Extended period permits are not authorized for transportable homes as defined in W.S. 31-1-101.
(e) The application for any permit under this section shall specifically describe the applicant, individual or company, the vehicle or load to be operated or moved, and the particular highway to be used and whether the permit is requested for a single trip or for extended period operation. Each permit shall contain the following provisions: duration of permit, description of load or loads to be moved, section standards which are to be exceeded and the amount of excess authorized, description of equipment, route to be traveled and required operating procedures. Every permit issued under this act shall be carried with the vehicles or combination of vehicles to which it refers and shall be open to inspection by any authorized agent of the state of Wyoming. Permission may be verbally issued by telephone or otherwise, granting the applicant authorization to proceed to the nearest permit issuing facility to be weighed and measured and to obtain the permit. Unless otherwise authorized by the director or his authorized representative, permits shall be obtained prior to operating any oversize or overweight vehicles on the highways of this state. Nothing herein contained shall be construed to permit a vehicle that is overweight or oversize and has not obtained a permit or permission in advance to be operated on the highways of this state. Except as provided in W.S. 31-18-805(b) and this subsection, the operator shall be required to unload the excess weight, reduce the excess size or otherwise bring the load within permissible limits and pay all fees for overweight or oversize under this act for distance traveled in addition to penalties provided by law.
(f) When an oversize single trip permit is issued, the fee is twenty-five dollars ($25.00). Should any vehicle including load exceed the dimensions of fifteen (15) feet in width or fifteen (15) feet in height or any single vehicle including load exceed seventy-five (75) feet in length, an additional fee shall be paid in excess of the above limitation computed at the rate of three cents ($.03) for each foot or fraction thereof for each mile traveled on the highways.
(g) When an overweight permit is issued, the fee is six cents ($.06) for each ton or fraction thereof of weight in excess of the weight limitation under W.S. 31-18-802 for each mile traveled on the highways. In no event shall the fee be less than forty dollars ($40.00) for the permit. A permit under this section for loads exceeding eighty (80) tons shall not be issued until the permittee has paid all costs incurred by the state to determine routing, structure, highway capability to withstand the load and the cost incurred by sending personnel to accompany the movement of the load.
(h) In addition to other permits authorized in this act, the director may issue permits to be completed by the applicant. These permits shall authorize separate movements of items that cannot be readily dismantled or divided, or safely transported if dismantled or divided. The applicant is required to complete a separate permit prior to each separate movement. The fee for the permit is that established in subsections (f) and (g) of this section.
(j) The director may promulgate rules and regulations as to the terms and conditions of the permits issued under this article. Alteration of any word or figure on the face of a permit will void the permit immediately and will subject the permit to confiscation by the inspecting officer.
