SUBCHAPTER A – GENERAL PERMIT PROVISIONS

3.

DEPARTMENT AUTHORITY AND RESPONSIBILITY

1.
Primary Concern. The Department’s primary concern, in the issuance of special permits, will be
the safety and conveyance of the general public and the preservation of the highway infrastructure.
2.
Permit Issuance. The Department will, in each case, predicate the issuance of a special permit ona reasonable determination of the necessity and feasibility of the proposed movement. Permits will be issued to specific vehicles.
3.
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 byroute 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 ofstate highway construction projects do not require special permits, but the loads must comply with the weight limits
specified in the state highway contract.
4.
Offices For Issuance Of Special Permits. The Department will make access to permits available
electronically, over the phone, and in person at Ports of Entry, as practicable.
4.

LOCAL HIGHWAY JURISDICTION AUTHORITY.

1.
Local Highway Jurisdictions. At their discretion, a Local Highway Jurisdiction may enter into anagreement with the Department to allow for the issuance of special permit to include travel on that local jurisdiction
controlled highways.
5.

PERMITTEE RESPONSIBILITY

1.
General Responsibilities. The permittee will determine and declare the gross weight, distributionof weight, and the dimensions of the vehicle and load and submit all other required information before issuance ofthe permit. Accepting a special permit by the permittee is his agreement that the vehicle and load covered by thepermit 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.
2.
Application for Special Permits. Applications can be completed Online, at Ports of Entry, orwith the Commercial Vehicle Services.
a.
An application must be submitted for all special permits. Applicants must provide all the information requested by the department to assist in the determination of the necessity of the proposed movement and theneed for an engineering determination of the feasibility of the proposed movement.
3.
Permit to Be Carried in Vehicle. The special permit must be carried or available electronically inthe vehicle to which it refers during the time of movement and, upon demand, be delivered for inspection to any
peace officer or authorized agent of the Idaho Transportation Board or any officer or employee charged with the careand protection of the public highways.
4.
Basic Limitations Will Not Be Exceeded. Special permits will not be issued for vehicles or loads
in excess of the maximum limitations of size or weight, or that otherwise exceed the limitations for loads as set forthin these rules unless an exception is made by the Transportation Board, or as otherwise provided herein. (3-21-22)
5.
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

Section 000

Page 3

BFloyd_05232023

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.
6.
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 forchecking 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: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.
b.

The driver reasonably knows that hazardous road conditions exist along route.

c.

Whenever a road is marked “Difficult” on 511 or as having a hazardous condition.

d.

Hazardous road conditions may include, but are not limited to:i.

Loss of traction on roadways due to ice, snow, frost, excessive water, or mud;ii.

Whenever a roadway is under conditions of wind over forty (40) mph;iii.

Visibility is less than five hundred (500) feet due to snow, rain, smoke, dust, or fog;iv.

Whenever a roadway becomes obstructed due to snow, water, mud, rocks, or other debris; orv.

Whenever a roadway is subject to a natural disaster or emergency.

the Board may impose.
2.
Military Emergency Affecting National Security. Any movement by or for a military or othergovernment 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 channeledthrough the Commercial Vehicle Services within the Department.
3.
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 thevehicle before an oversize movement. Verbal approval to proceed without a special permit in the vehicle may beobtained 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.

Section 000

Page 5

BFloyd_05232023

4.
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 theemergency movement is completed, the permittee will formally apply for a permit with Commercial Vehicle Services on the first working day after the occurrence.
5.
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.
9.

SPRING BREAKUP SEASON LOAD RESTRICTIONS.

1.
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.
2.
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 thepavement may temporarily restore the load-bearing capacity after a section has been posted for load and speed restrictions.
3.
following:

Maximum Weight Restriction. The possible restrictions on maximum weight may be one of thea.

Sixteen thousand (16,000) pounds on any axle; orb.

Fourteen thousand (14,000) pounds on any axle; orc.

Twelve thousand (12,000) pounds on any axle.

4.
Weight Limits Based On Tire Sizes. In administering load limits based on tire sizes or width oftires, credit for tubed tires will be based on the manufacturer’s width marked on the tire; for example, a ten-pointzero-zero by twenty-four (10.00 x 24) tire will be given credit for ten (10”) inches of tire width. Tubeless tires willbe credited for the width of the conventional tubed tires they replace.
5.
Width Restrictions. When a weight restriction is applied under subsection 2 of this section it willautomatically restrict the width allowed by a special permit on two lane road. On any two lane section of state roadways restricted to less than legal weight, the maximum width by the special permit will be restricted to twelve feetsix (12’6”) inches during the weight restriction period.
6.
Speed Restrictions. When a weight restriction is applied under subsection 2 of this section it willautomatically 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.
Suspended Weight Limits. Normal overweight special permit limits may be suspended on all
highways in the areas where spring breakup restriction are in force.
8.
Weight Restrictions. The department is authorized to issue special permits to overweight vehicles inareas with spring breakup restrictions as long as all of the following conditions are met:a.

Minimum tire width on all tires is ten (10”) inches or larger, and;b.

Maximum axle weight on any single axle having two (2) single wheels will not exceed ten thou-

Section 000

Page 6

BFloyd_05232023

sand (10,000) pounds, and;c.

Maximum axle weight on any single axle having four (4) or more tires will not exceed fourteen thousand (14,000) pounds, and;d.

Permit is being requested for a non-divisible loads

9.
Temporary Waiver of Spring Breakup Restrictions. The department may temporarily waive thespring 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 forother circumstances.
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 fromthe department and must be carried in the vehicle.
11.
Restriction Signage. The department will sign and mark affected state highways the day before theweight and/or speed restrictions are in effect. The weight and/or speed restrictions will be enforced the day after signs
and marks are posted.
10.

1.
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 frommilepost 74 to 174). The Forest Service has issued the following written criteria to determine which “oversize”
loads will be subject to Forest Service review: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.
posts.

b.

Load movement requires longer than twelve (12) hours to travel through the designated mile-c.
Load movement requires physical modification of the roadway or adjacent vegetation to facilitate passage beyond normal highway maintenance.
2.
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:a.

Ambulances and possible law enforcement escorts to ensure public safety.

b.

Safety lighting will be addressed to not create a safety hazard to the traveling public.

MAXIMUM OVERWEIGHT LEVELS FOR ANNUAL OVERWEIGHT/OVERSIZE PERMITS

1.
Allowable Gross Vehicle Weight. The gross vehicle weight allowable by overweight permit issubject 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 ofw = 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. “l” is the distance in feet between the extremes of anygroup of two (2) or more consecutive axles, “n” is the number of axles under consideration. The load factor basedon the most critical bridge on the highway route will also be used in determining allowable weights.
2.
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.
3.
Yellow Routes. The yellow overweight level is based on a single axle loading of twenty-two
thousand five hundred (22,500) pounds, a tandem axle loading of thirty-eight thousand (38,000) pounds, and atridem axle loading of forty-eight thousand (48,000) pounds or the equivalent loading as determined by spacingsand the number of axles and computed by applying the formula W = 560 ((LN/N-1) + 12N + 36).
4.
Orange Routes. Orange overweight level is based on a single axle loading of twenty-four thousand (24,000) pounds, a tandem axle loading of forty-one thousand (41,000) pounds, and a tridem axle loading offifty-one thousand five hundred (51,500) pounds or the equivalent loading as determined by spacings and thenumber of axles and computed by applying the formula W = 600 ((LN/N-1) + 12N + 36). (3-31-22)
5.
Green Routes. The green overweight level is based on a single axle loading of twenty-fivethousand five hundred (25,500) pounds, a tandem axle loading of forty-three thousand five hundred (43,500)
pounds, and a tridem axle loading of fifty-four thousand five hundred (54,500) pounds or the equivalent loading as
determined by spacings and the number of axles and computed by applying the formula W = 640 ((LN/N-1) +12N + 36).
6.
Blue Routes. Blue overweight level is based on a single axle loading of twenty-seven thousand(27,000) pounds, a tandem axle loading of forty-six thousand (46,000) pounds, and a tridem axle loading of fiftyseven thousand five hundred (57,500) pounds or the equivalent loading as determined by spacings and the numberof axles and computed by applying the formula W = 675 ((LN/N-1) + 12N + 36).
(3-31-22)
7.
Purple Routes. The purple overweight level is based on a single axle loading of thirty thousand(30,000) pounds, a tandem axle loading of fifty-one thousand five hundred (51,500) pounds, and a tridem axle
loading of sixty-four thousand five hundred (64,500) pounds or the equivalent loading as determined by spacingsand the number of axles and computed by applying the formula W = 755 ((LN/N-1) + 12N + 36). (3-31-22)
8.
Black Routes. The black overweight level is based on a single axle loading of thirty-three thousand (33,000), pounds a tandem axle loading of fifty-six thousand (56,000) pounds, and a tridem axle loading ofseventy thousand five hundred (70,500) pounds or the equivalent loading as determined by spacings and the number of axles and computed by applying the formula W = 825 ((LN/N-1) + 12N + 36).

QUARTERLY ROAD USE FEE REPORTS FOR ANNUAL OVERWEIGHT PERMITS.

1.
Quarterly Reporting. To comply with Section 49-1001, Idaho Code, permittees must makequarterly reports of laden only mileage to the department for the movements of non-divisible vehicle/loads, at theappropriate permitted weight level of the annual special permits. These fees are in addition to the registration fees
Mileage and road use fees for single trip special permits are calculated and collected at the time of issuance andare not reported quarterly. Reporting is required as follows:a.
mit issued.

The department will generate an online quarterly report form for each valid annual special per-b.
The permittee must report each quarter’s information on the department’s form with all requested information completed on or before the specified due date even when reporting zero (0) miles traveled.
c.
If the customer does not receive a quarterly report form or report their information online, it is
the customer’s responsibility to notify the department allowing adequate time to submit the report before the duedate.
d.
Any report transmitted through the US Postal Service is considered filed and received by the department on the date shown by the post office cancellation mark stamped on the envelope or wrapper containing

OVERSIZE LOADS.

1.
Continuous Operation. Special permits may be issued for continuous operation to haul ortransport non-divisible loads having specified maximum oversize dimensions provided such permits for multiple
trips can maintain the same measure of protection to highway facilities and to the traveling public as is provided
by single trip permits.
a.

Permits for continuous operation to be issued for oversize loads only.

b.
Permits for continuous operation will be issued to one (1) specified power unit. The permittee
may tow various units with the specified power unit, either as towaway vehicles or trailers, hauling oversizedloads. Oversize loads will be non-divisible in width, length, or height. In the case of specially constructed equipment, mounted on a towed vehicle, or if the towed vehicle is only hauling an oversize but not overweight load, thepermit may be issued to the towed vehicle.
c.
Maximum size of loads or vehicles transported under the authority of an annual oversize forblack and interstate routes will be limited to a width of sixteen (16’) feet, a height of fifteen feet six inches(15’6”), and to a combination length of one hundred twenty (120’) feet including load overhang.

OVERWIDTH PERMITS FOR IMPLEMENTS OF HUSBANDRY.

1.
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

Section 000

Page 18

BFloyd_05232023

annual permits under this rule for transportation of farm tractors, having a width in excess of nine (9’) feet to orfrom 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, andmust operate under oversize permits.
2.
Other Than Farm to Farm. Implements of husbandry exceeding eight feet six inches (8’6”) in
width being transported require a special permit to move, except for the following situations:a.

The implement is being moved from one (1) farm operation to another farm operationb.
A farmer, employee or relative of the owner of the implement, or equipment dealer is transporting implements of husbandry or equipment for the purpose of:i.
The repair or maintenance of such implements of husbandry and equipment when traveling to orfrom a farm to a repair or maintenance facility during daylight hours; orii.
The purchase, sale, lease or rental of such implements of husbandry or equipment when traveling between a farm and a dealership, auction house, or other facility during daylight hours.
3.
Farm Permits. Annual permits will be issued to towing units or to self-propelled farm tractors
or towed units, or blanket permits may be issued to an Idaho domicile applicant without vehicle identification.
Such blanket permits may be transferred from one (1) vehicle to another vehicle but will be valid only when thepermit is with the overwidth vehicle and/or load. A photocopy of the permit is valid, provided that the Pilot/Escort
Vehicle Travel and Vertical Clearance of Structures Map furnished by the Idaho Transportation Department areincluded. Such annual permits for implements of husbandry or farm tractors are subject to the same maximum
dimensions, travel time exclusions, and safety requirements as other overwidth annual permits.
4.
Overwidth Farm Trailers. Trailers or semi-trailers exceeding eight feet six inches (8’ 6”) wide,
but not wider than the implement of husbandry, used for the transportation of implements of husbandry to or froma farm for agricultural operations, will be exempt from special permitting requirements. This exemption does not
apply to trailers or semi-trailers used in common carrier operations, hauling for hire or used in the furtherance of abusiness (not to include farming operations)a.
Exempt trailers, as listed above, may not be used to haul implements of husbandry that are narrower than the overwidth trailer.
b.
Empty trailers, as listed above, being used to pick up or drop off an implement of husbandry
from a farm to a farm are also exempt and must be reduced to a practical minimum dimension (i.e. dropping side
extensions).
