625 ILCS 5/15-301 : TRANSPORTATION — VEHICLES — ILLINOIS VEHICLE CODE — CHAPTER 15. SIZE, WEIGHT, LOAD AND PERMITS — PERMITS —301 - Permits for excess size and weight

(a) The Department with respect to highways under its jurisdiction and local authorities with respect to highways under their jurisdiction may, in their discretion, upon application and good cause being shown therefor, issue a special permit authorizing the applicant to operate or move a vehicle or combination of vehicles of a size or weight of vehicle or load exceeding the maximum specified in this Code or otherwise not in conformity with this Code upon any highway under the jurisdiction of the party granting such permit and for the maintenance of which the party is responsible. Applications and permits other than those in written or printed form may only be accepted from and issued to the company or individual making the movement. Except for an application to move directly across a highway, it shall be the duty of the applicant to establish in the application that the load to be moved by such vehicle or combination cannot reasonably be dismantled or disassembled, the reasonableness of which shall be determined by the Secretary of the Department. For the purpose of over length movements, more than one object may be carried side by side as long as the height, width, and weight laws are not exceeded and the cause for the over length is not due to multiple objects. For the purpose of over height movements, more than one object may be carried as long as the cause for the over height is not due to multiple objects and the length, width, and weight laws are not exceeded. For the purpose of an over width movement, more than one object may be carried as long as the cause for the over width is not due to multiple objects and length, height, and weight laws are not exceeded. Except for transporting fluid milk products, no State or local agency shall authorize the issuance of excess size or weight permits for vehicles and loads that are divisible and that can be carried, when divided, within the existing size or weight maximums specified in this Chapter. Any excess size or weight permit issued in violation of the provisions of this Section shall be void at issue and any movement made thereunder shall not be authorized under the terms of the void permit. In any prosecution for a violation of this Chapter when the authorization of an excess size or weight permit is at issue, it is the burden of the defendant to establish that the permit was valid because the load to be moved could not reasonably be dismantled or disassembled, or was otherwise nondivisible.
(a-1) As used in this Section, "extreme heavy duty tow and recovery vehicle" means a tow truck manufactured as a unit having a lifting capacity of not less than 50 tons, and having either 4 axles and an unladen weight of not more than 80,000 pounds or 5 axles and an unladen weight not more than 90,000 pounds. Notwithstanding otherwise applicable gross and axle weight limits, an extreme heavy duty tow and recovery vehicle may lawfully travel to and from the scene of a disablement and clear a disabled vehicle if the towing service has obtained an extreme heavy duty tow and recovery permit for the vehicle. The form and content of the permit shall be determined by the Department with respect to highways under its jurisdiction and by local authorities with respect to highways under their jurisdiction.
(b) The application for any such permit shall: (1) state whether such permit is requested for a single trip or for limited continuous operation; (2) (blank); (3) specifically describe and identify the vehicle or vehicles and load to be operated or moved; (4) state the routing requested, including the points of origin and destination, and may identify and include a request for routing to the nearest certified scale in accordance with the Department's rules and regulations, provided the applicant has approval to travel on local roads; and (5) (blank).
(c) The Department or local authority when not inconsistent with traffic safety is authorized to issue or withhold such permit at its discretion; or, if such permit is issued at its discretion to prescribe the route or routes to be traveled, to limit the number of trips, to establish seasonal or other time limitations within which the vehicles described may be operated on the highways indicated, or otherwise to limit or prescribe conditions of operations of such vehicle or vehicles, when necessary to assure against undue damage to the road foundations, surfaces or structures, and may require such undertaking or other security as may be deemed necessary to compensate for any injury to any roadway or road structure. The Department shall maintain a daily record of each permit issued along with the fee and the stipulated dimensions, weights, conditions, and restrictions authorized and this record shall be presumed correct in any case of questions or dispute. The Department shall install an automatic device for recording telephone conversations involving permit applications. The Department and applicant waive all objections to the recording of the conversation.
(d) The Department shall, upon application in writing from any local authority, issue an annual permit authorizing the local authority to move oversize highway construction, transportation, utility, and maintenance equipment over roads under the jurisdiction of the Department. The permit shall be applicable only to equipment and vehicles owned by or registered in the name of the local authority, and no fee shall be charged for the issuance of such permits.
(e) As an exception to subsection (a) of this Section, the Department and local authorities, with respect to highways under their respective jurisdictions, in their discretion and upon application in writing, may issue a special permit for limited continuous operation, authorizing the applicant to move loads of agricultural commodities on a 2-axle single vehicle registered by the Secretary of State with axle loads not to exceed 35%, on a 3-axle or 4-axle vehicle registered by the Secretary of State with axle loads not to exceed 20%, and on a 5-axle vehicle registered by the Secretary of State not to exceed 10% above those provided in Section 15-111. The total gross weight of the vehicle, however, may not exceed the maximum gross weight of the registration class of the vehicle allowed under Section 3-815 or 3-818 of this Code.

As used in this Section, "agricultural commodities" means:

(1) cultivated plants or agricultural produce grown, including, but not limited to, corn, soybeans, wheat, oats, grain sorghum, canola, and rice;
(2) livestock, including, but not limited to, hogs, equine, sheep, and poultry;
(3) ensilage; and
(4) fruits and vegetables.

Permits may be issued for a period not to exceed 40 days and moves may be made of a distance not to exceed 50 miles from a field, an on-farm grain storage facility, a warehouse as defined in the Grain Code, or a livestock management facility as defined in the Livestock Management Facilities Act over any highway except the National System of Interstate and Defense Highways. The operator of the vehicle, however, must abide by posted bridge and posted highway weight limits. All implements of husbandry operating under this Section between sunset and sunrise shall be equipped as prescribed in Section 12-205.1.

(e-1) A special permit shall be issued by the Department under this Section and shall be required from September 1 through December 31 for a vehicle that exceeds the maximum axle weight and gross weight limits under Section 15-111 of this Code or exceeds the vehicle's registered gross weight, provided that the vehicle's axle weight and gross weight do not exceed 10% above the maximum limits under Section 15-111 of this Code and does not exceed the vehicle's registered gross weight by 10%. All other restrictions that apply to permits issued under this Section shall apply during the declared time period and no fee shall be charged for the issuance of those permits. Permits issued by the Department under this subsection (e-1) are only valid on federal and State highways under the jurisdiction of the Department, except interstate highways. With respect to highways under the jurisdiction of local authorities, the local authorities may, at their discretion, waive special permit requirements and set a divisible load weight limit not to exceed 10% above a vehicle's registered gross weight, provided that the vehicle's axle weight and gross weight do not exceed 10% above the maximum limits specified in Section 15-111. Permits issued under this subsection (e-1) shall apply to all registered vehicles eligible to obtain permits under this Section, including vehicles used in private or for-hire movement of divisible load agricultural commodities during the declared time period.
(f) The form and content of the permit shall be determined by the Department with respect to highways under its jurisdiction and by local authorities with respect to highways under their jurisdiction. Every permit shall be in written form and carried in the vehicle or combination of vehicles to which it refers and shall be open to inspection by any police officer or authorized agent of any authority granting the permit and no person shall violate any of the terms or conditions of such special permit. Violation of the terms and conditions of the permit shall not be deemed a revocation of the permit; however, any vehicle and load found to be off the route prescribed in the permit shall be held to be operating without a permit. Any off-route vehicle and load shall be required to obtain a new permit or permits, as necessary, to authorize the movement back onto the original permit routing. No rule or regulation, nor anything herein, shall be construed to authorize any police officer, court, or authorized agent of any authority granting the permit to remove the permit from the possession of the permittee unless the permittee is charged with a fraudulent permit violation as provided in subsection (i). However, upon arrest for an offense of violation of permit, operating without a permit when the vehicle is off route, or any size or weight offense under this Chapter when the permittee plans to raise the issuance of the permit as a defense, the permittee, or his agent, must produce the permit at any court hearing concerning the alleged offense.

If the permit designates and includes a routing to a certified scale, the permittee, while en route to the designated scale, shall be deemed in compliance with the weight provisions of the permit provided the axle or gross weights do not exceed any of the permitted limits by more than the following amounts:

Single axle

2000 pounds

Tandem axle

3000 pounds

Gross

5000 pounds
(g) The Department is authorized to adopt, amend, and make available to interested persons a policy concerning reasonable rules, limitations and conditions or provisions of operation upon highways under its jurisdiction in addition to those contained in this Section for the movement by special permit of vehicles, combinations, or loads which cannot reasonably be dismantled or disassembled, including manufactured and modular home sections and portions thereof. All rules, limitations and conditions or provisions adopted in the policy shall have due regard for the safety of the traveling public and the protection of the highway system and shall have been promulgated in conformity with the provisions of the Illinois Administrative Procedure Act. The requirements of the policy for flagmen and escort vehicles shall be the same for all moves of comparable size and weight. When escort vehicles are required, they shall meet the following requirements:
(1) All operators shall be 18 years of age or over and properly licensed to operate the vehicle.
(2) Vehicles escorting oversized loads more than 12 feet wide must be equipped with a rotating or flashing amber light mounted on top as specified under Section 12-215.

The Department shall establish reasonable rules and regulations regarding liability insurance or self insurance for vehicles with oversized loads promulgated under the Illinois Administrative Procedure Act. Police vehicles may be required for escort under circumstances as required by rules and regulations of the Department.

(h) Violation of any rule, limitation or condition or provision of any permit issued in accordance with the provisions of this Section shall not render the entire permit null and void but the violator shall be deemed guilty of violation of permit and guilty of exceeding any size, weight, or load limitations in excess of those authorized by the permit. The prescribed route or routes on the permit are not mere rules, limitations, conditions, or provisions of the permit, but are also the sole extent of the authorization granted by the permit. If a vehicle and load are found to be off the route or routes prescribed by any permit authorizing movement, the vehicle and load are operating without a permit. Any off-route movement shall be subject to the size and weight maximums, under the applicable provisions of this Chapter, as determined by the type or class highway upon which the vehicle and load are being operated.
(i) Whenever any vehicle is operated or movement made under a fraudulent permit, the permit shall be void, and the person, firm, or corporation to whom such permit was granted, the driver of such vehicle in addition to the person who issued such permit and any accessory, shall be guilty of fraud and either one or all persons may be prosecuted for such violation. Any person, firm, or corporation committing such violation shall be guilty of a Class 4 felony and the Department shall not issue permits to the person, firm, or corporation convicted of such violation for a period of one year after the date of conviction. Penalties for violations of this Section shall be in addition to any penalties imposed for violation of other Sections of this Code.
(j) Whenever any vehicle is operated or movement made in violation of a permit issued in accordance with this Section, the person to whom such permit was granted, or the driver of such vehicle, is guilty of such violation and either, but not both, persons may be prosecuted for such violation as stated in this subsection (j). Any person, firm, or corporation convicted of such violation shall be guilty of a petty offense and shall be fined, for the first offense, not less than $50 nor more than $200 and, for the second offense by the same person, firm, or corporation within a period of one year, not less than $200 nor more than $300 and, for the third offense by the same person, firm, or corporation within a period of one year after the date of the first offense, not less than $300 nor more than $500 and the Department may, in its discretion, not issue permits to the person, firm, or corporation convicted of a third offense during a period of one year after the date of conviction or supervision for such third offense. If any violation is the cause or contributing cause in a motor vehicle crash causing damage to property, injury, or death to a person, the Department may, in its discretion, not issue a permit to the person, firm, or corporation for a period of one year after the date of conviction or supervision for the offense.
(k) Whenever any vehicle is operated on local roads under permits for excess width or length issued by local authorities, such vehicle may be moved upon a State highway for a distance not to exceed one-half mile without a permit for the purpose of crossing the State highway.
(l) Notwithstanding any other provision of this Section, the Department, with respect to highways under its jurisdiction, and local authorities, with respect to highways under their jurisdiction, may at their discretion authorize the movement of a vehicle in violation of any size or weight requirement, or both, that would not ordinarily be eligible for a permit, when there is a showing of extreme necessity that the vehicle and load should be moved without unnecessary delay.

For the purpose of this subsection, showing of extreme necessity shall be limited to the following: shipments of livestock, hazardous materials, liquid concrete being hauled in a mobile cement mixer, or hot asphalt.

(m) Penalties for violations of this Section shall be in addition to any penalties imposed for violating any other Section of this Code.
(n) The Department with respect to highways under its jurisdiction and local authorities with respect to highways under their jurisdiction, in their discretion and upon application in writing, may issue a special permit for continuous limited operation, authorizing the applicant to operate a tow truck that exceeds the weight limits provided for in subsection (a) of Section 15-111, provided:
(1) no rear single axle of the tow truck exceeds 26,000 pounds;
(2) no rear tandem axle of the tow truck exceeds 50,000 pounds;
(2.1) no triple rear axle on a manufactured recovery unit exceeds 60,000 pounds;
(3) neither the disabled vehicle nor the disabled combination of vehicles exceed the weight restrictions imposed by this Chapter 15, or the weight limits imposed under a permit issued by the Department prior to hookup;
(4) the tow truck prior to hookup does not exceed the weight restrictions imposed by this Chapter 15;
(5) during the tow operation the tow truck does not violate any weight restriction sign;
(6) the tow truck is equipped with flashing, rotating, or oscillating amber lights, visible for at least 500 feet in all directions;
(7) the tow truck is specifically designed and licensed as a tow truck;
(8) the tow truck has a gross vehicle weight rating of sufficient capacity to safely handle the load;
(9) the tow truck is equipped with air brakes;
(10) the tow truck is capable of utilizing the lighting and braking systems of the disabled vehicle or combination of vehicles;
(11) the tow commences at the initial point of wreck or disablement and terminates at a point where the repairs are actually to occur;
(12) the permit issued to the tow truck is carried in the tow truck and exhibited on demand by a police officer; and
(13) the movement shall be valid only on State routes approved by the Department.
(o) (Blank).
(p) In determining whether a load may be reasonably dismantled or disassembled for the purpose of subsection (a), the Department shall consider whether there is a significant negative impact on the condition of the pavement and structures along the proposed route, whether the load or vehicle as proposed causes a safety hazard to the traveling public, whether dismantling or disassembling the load promotes or stifles economic development, and whether the proposed route travels less than 5 miles. A load is not required to be dismantled or disassembled for the purposes of subsection (a) if the Secretary of the Department determines there will be no significant negative impact to pavement or structures along the proposed route, the proposed load or vehicle causes no safety hazard to the traveling public, dismantling or disassembling the load does not promote economic development, and the proposed route travels less than 5 miles. The Department may promulgate rules for the purpose of establishing the divisibility of a load pursuant to subsection (a). Any load determined by the Secretary to be nondivisible shall otherwise comply with the existing size or weight maximums specified in this Chapter.
