03. Special Permit. The special permit authority of the Department will cover travel on state roadways only, unless the Department has an existing agreement under subsection 004 of this rule. Special permits issued by the Department will be valid only on completed sections of state roadways, as described on the permit by route number or otherwise. The right to use county highways or city streets is neither granted nor implied. The special permit authority of the Department will include those sections of state roadways within corporate limits of cities and towns. Still, it will not include sections of state roadways intersecting with local highways, when travel is occurring on the local highway(s). Additionally, it will not release the permittee from complying with other existing laws, local ordinances, or resolutions which may also govern their movement. Contractors hauling loads within the limits of state highway construction projects do not require special permits, but the loads must comply with the weight limits specified in the state highway contract. (7-1-24)

01. General Responsibilities. The permittee will determine and declare the gross weight, distribution of weight, and the dimensions of the vehicle and load and submit all other required information before issuance of the permit. Accepting a special permit by the permittee is his agreement that the vehicle and load covered by the permit can and will be moved in compliance with the terms and limitations set forth in the permit. When a permit has been accepted by the permittee, such action will be deemed an unequivocal assurance that he has complied, or will comply with all operating, licensing, and financial responsibility requirements. (7-1-24)
02. Application for Special Permits. Applications can be completed Online, at Ports of Entry, or with the Commercial Vehicle Services. (7-1-24)
a. An application must be submitted for all special permits.

05. Insurance For Extraordinary Hazards. Evidence of insurance is required when necessary because loads create an extraordinary hazard to the traveling public or to protect the public investment when a load presents an extraordinary hazard to the highway system. In such cases of extraordinary hazard to the roadway or structures, the Department may require insurance in such amount as to cover the maximum damage that could be expected to occur to the highway, with the permittee also required to reimburse the Department for any engineering required to ascertain the extent of damages, if any, occurring to the roadway during the movement of the excessive load. (7-1-24)
06. Hazardous Travel Conditions Restrictions. Extreme caution in the operation of a special-permitted vehicle will be exercised when hazardous conditions exist. The driver of a permitted vehicle is responsible for checking the conditions of the permitted route before travel. The movement of vehicles or loads operating on valid permits will automatically become invalid en route when: (7-1-24)
a. The Idaho Transportation Department, Idaho State Police, or other law enforcement office determines and provides public notice by any available means that a hazardous road condition exists. (7-1-24)
b. The driver reasonably knows that hazardous road conditions exist along route. (7-1-24)

01. Board Authority. Notwithstanding other provisions of these rules, the Idaho Transportation Board may waive existing permit policy limitations in an emergency, subject to such limitations or special requirements as the Board may impose. (7-1-24)
02. Military Emergency Affecting National Security. Any movement by or for a military or other government agency which is in excess of permit policy maximum limits of weight or size or which is otherwise outside established rules must be certified as a military necessity involving national security before receiving any special consideration to provide any waiver of normal permit rules. Certification of military necessity must be made by an official designated as having such authority by the Department of Defense Directory, issued by the Office of the Chief of Transportation, Department of Army. All applications for military emergency movements must be channeled through the Commercial Vehicle Services within the Department. (7-1-24)
03. Emergencies Endangering the Public Health, Safety, or Welfare, Including but Not Limited to Fire, Flood, or Earthquake. During an emergency endangering public health, safety, or welfare, there may be an urgent and immediate need for equipment. It will not be in the public interest to require a special permit to be in the vehicle before an oversize movement. Verbal approval to proceed without a special permit in the vehicle may be obtained from the Commercial Vehicle Services or an Idaho Port-of-Entry. Once the emergency movement is completed, a formal application for a special permit must be submitted to Commercial Vehicle Services. (7-1-24)
04. Emergency Movement of Implements of Husbandry. It will be considered an emergency when an implement of husbandry being operated on an official state holiday or a weekend breaks down and a dealer brings replacement equipment to the farmer that exceeds legal height, length, and weight. Verbal approval to proceed without a special permit in the vehicle may be obtained from Commercial Vehicle Service on-call staff. That verbal authorization may include escort vehicle requirements based on the travel route and the load's dimensions. Once the emergency movement is completed, the permittee will formally apply for a permit with Commercial Vehicle Services on the first working day after the occurrence. (7-1-24)
05. Economic Emergencies. When a circumstance occurs in which an economic hardship is expected to result due to the application of existing rules or limitations, the Transportation Board may consider a petition for the temporary waiver of those rules or limitations which are perceived as being the cause of such economic hardship. (7-1-24)
106. SPRING BREAKUP SEASON LOAD RESTRICTIONS.
01. Authority. The Department will have the authority to impose restrictions on sections of State roadways in order to ensure the safe travel for the citizens of Idaho and to protect the infrastructure of the state during periods of severe spring breakup. The Department, as much as practicable, will maintain standard load limits on these roads unless conditions are such that severe breakup will result. (7-1-24)
02. Spring Breakup Restrictions. Depending upon the type of road construction, stability of the roadway, reduction in load bearing capacity, the amount of moisture, temperature conditions, and severity of frost heaves and breakup, routes or sections of routes may have restrictions applied by the department. A freeze-up of the pavement may temporarily restore the load-bearing capacity after a section has been posted for load and speed restrictions. (7-1-24)
03. Maximum Weight Restriction. The possible restrictions on maximum weight may be one (1) of the following: (7-1-24)
a. Sixteen thousand (16,000) pounds on any axle; or (7-1-24) b. Fourteen thousand (14,000) pounds on any axle; or (7-1-24) c. Twelve thousand (12,000) pounds on any axle. (7-1-24)
04. Weight Limits Based On Tire Sizes. In administering load limits based on tire sizes or width of tires, credit for tubed tires will be based on the manufacturer's width marked on the tire; for example, a ten-point zero-zero by twenty-four (10.00 x 24) tire will be given credit for ten inches (10") of tire width. Tubeless tires will be
credited for the width of the conventional tubed tires they replace. (7-1-24)
05. Width Restrictions. When a weight restriction is applied under Subsection 106.02 of this section it will automatically restrict the width allowed by a special permit on two lane road. On any two (2) lane section of state roadways restricted to less than legal weight, the maximum width by the special permit will be restricted to twelve feet six inches (12'6') during the weight restriction period. (7-1-24)
06. Speed Restrictions. When a weight restriction is applied under Subsection 106.02 of this section it will automatically restrict the speed of some vehicles. Trucks and buses with a gross weight of ten thousand (10,000) pounds or more will be restricted in critical areas to a maximum speed of thirty (30) miles per hour. Red and green markers will mark restricted speed zones. A red marker will mean speed is restricted to thirty (30) miles per hour, and a green marker will mean that legal speed may be resumed. These markers will generally be attached to existing highway signposts and, when properly used, will afford protection to the highway subgrade and surface and speed traffic flow. (7-1-24)
07. Suspended Weight Limits. Normal overweight special permit limits may be suspended on all highways in the areas where spring breakup restriction are in force. (7-1-24)
08. Weight Restrictions. The department is authorized to issue special permits to overweight vehicles in areas with spring breakup restrictions as long as all of the following conditions are met: (7-1-24)
a. Minimum tire width on all tires is ten inches (10') or larger, and; (7-1-24)
b. Maximum axle weight on any single axle having two (2) single wheels will not exceed ten thousand (10,000) pounds, and; (7-1-24)
c. Maximum axle weight on any single axle having four (4) or more tires will not exceed fourteen thousand (14,000) pounds, and; (7-1-24)
d. Permit is being requested for a non-divisible loads. (7-1-24)
09. Temporary Waiver of Spring Breakup Restrictions. The department may temporarily waive the spring breakup restrictions by posting GREEN markers on the speed limit signs and other signs, if appropriate, within a section of the highway posted with restrictions. This may occur in the event that a freeze-up of the pavement may temporarily restore the load-bearing capacity after a section has been posted for load and speed restrictions or for other circumstances. (7-1-24)
10. Spring Breakup Restriction Waivers. The department may allow exceptions to the spring breakup weight restrictions for emergency and critical service vehicle(s), i.e. fire trucks, heating fuel trucks, and other such service vehicles that are critical to the health and safety of the public. Documentation of special allowance will be in writing from the department and must be carried in the vehicle. (7-1-24)
11. Restriction Signage. The department will sign and mark affected state highways the day before the weight and/or speed restrictions are in effect. The weight and/or speed restrictions will be enforced the day after signs and marks are posted. (7-1-24)
01. Special Permit Fees To Be Borne By Permittee. The movement of oversize or overweight vehicles or vehicles with special loads is a privilege not afforded to every highway user. The administrative cost incurred in the processing, issuing, and enforcing of special permits will be borne by such permittees and not by the general traveling public through the expenditure of highway user funds. Special permits issued for non-divisible, overweight vehicles and/or loads will be charged a road use fee as set forth in Section 49-1004(2), Idaho Code. Tax-supported agencies are required to obtain special permits if their loads exceed the sizes or weights stated in Idaho Code, but they are exempt from paying fees for the permits. (7-1-24)
02. Payment of Fees. Permit fees are due at the time of issuance. (7-1-24)
03. Refund. Permit fees are not refundable once they have been processed into the Department's accounting system unless the permittee contacts Commercial Vehicle Services no more than two (2) working days (during office hours) following the start date of the special permit or the Department issued the special permit in error. (7-1-24)
04. Permit Costs. Special permit fees listed below are intended to cover the administration cost and are subject to periodic change depending on costs incurred in processing, issuance, and enforcement of special permit rules. (7-1-24)

13. Advance Pilot/Escort Vehicle. A third pilot/escort vehicle may be required when the load is of such extreme dimensions for the route of travel as to require holding opposing traffic at turnouts and intersections to provide for passage of the load. (7-1-24)
14. First Movement from the Forest. A pilot/escort vehicle is not required on the first movement from the forest of tree-length logs or poles if the overall length does not exceed one hundred ten (110’) feet. Secondary movements must comply with the requirements stated on the Pilot/Escort Vehicle and Travel Time Requirements map. (7-1-24)
15. Spacing. Approximately one thousand (1,000’) feet will be maintained in rural areas between the piloting/escorting vehicle and any oversize load. This spacing may be reduced in urban areas when necessary to provide traffic control for turning movements. (7-1-24)
01. Forest Service Oversight. Pursuant to a Federal Court decision, the United States Forest Service has the duty to regulate oversize loads traveling through the Nez Perce – Clearwater Forest (US 12 from milepost 74 to 174). The Forest Service has issued the following written criteria to determine which “oversize” loads will be subject to Forest Service review: (7-1-24)
a. Load exceeds sixteen (16) feet wide, one hundred and fifty thousand pounds (150,000 lbs.), and/or one hundred and fifty (150) feet in length. (7-1-24)
b. Load movement requires longer than twelve (12) hours to travel through the designated mileposts. (7-1-24)
c. Load movement requires physical modification of the roadway or adjacent vegetation to facilitate passage beyond normal highway maintenance. (7-1-24)
02. Additional Safety Requirements. For loads meeting any of the criteria this section of this rule, there will be additional safety requirements for the movement of such loads on US 12 from milepost 74 to 174. These additional safety requirements include, at a minimum, the following: (7-1-24)
a. Ambulances and possible law enforcement escorts to ensure public safety. (7-1-24)
b. Safety lighting will be addressed to not create a safety hazard to the traveling public. (7-1-24)
c. Loads cannot utilize turnouts, which are designated for recreational vehicles for non-emergency parking. (7-1-24)
d. Time of travel will be determined based on traffic volume and best interest of the public. Nighttime
movement may be required and/or movement may be restricted during holidays or weekends. (7-1-24)
e. Loads require a vehicle safety inspection by the Idaho State Police or equivalent agency of another jurisdiction prior to issuance of a permit. (7-1-24)
f. The department will monitor the loads as they travel the highway and ensure only one (1) load will operate on this section of highway at any one time. (7-1-24)
01. Allowable Gross Vehicle Weight. The gross vehicle weight allowable by overweight permit is subject to the seasonal stability of the roadway and the capacity of the structures on the route of travel. For the purpose of issuing special permits, seven (7) levels of overweight are established, based on the weight formula of $w = 500((\ln n - 1) + 12n + 36)$ and routes for carrying the various levels of overweight are designated by color coding. The weight formula (“w”) is the maximum weight in pounds (to the nearest five hundred (500) pounds) carried on any group of two (2) or more consecutive axles. “1” is the distance in feet between the extremes of any group of two (2) or more consecutive axles, “n” is the number of axles under consideration. The load factor based on the most critical bridge on the highway route will also be used in determining allowable weights. (7-1-24)
02. Red Routes. The red routes contain posted bridges and require approval or analysis from the Department. A vehicle configuration may be issued an annual overweight/oversize permit for travel on red routes only, upon completion of an analysis verifying the requested weights are acceptable. The annual permit will be issued for a specific vehicle configuration, operating on a specific route, at specific weights. All information will be listed on the annual permit and will be subject to revocation at such time the vehicle configuration changes (such as axle spacings), the approved weights change, or a bridge rating changes. (7-1-24)

01. Farm Tractors on Interstate Highways. Farm tractors transported on Interstate Highways are required to have special permit authority if width exceeds nine (9') feet. A farm tractor when attached to an implement of husbandry or when drawing an implement of husbandry will be construed to be an implement of husbandry and no permit is necessary. Farmers, equipment dealers, or custom operators may be issued single trip or annual permits under this rule for transportation of farm tractors, having a width in excess of nine (9') feet to or from a farm involving Interstate Highway travel. The transportation of farm tractors or implements of husbandry for hire, or not being transported from one farm operation to another, is a common-carrier operation. Exemptions from legal width limitation do not apply to common-carrier operations. Farm tractors or implements of husbandry hauled for hire, or used in the furtherance of a business (not to include farming operations), are subject to the same special permit regulations as other oversize loads when the width of the load exceeds legal-width limitations, and must operate under oversize permits.
