Illinois Compiled Statutes

Information maintained by the Legislative Reference Bureau
Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process. Recent laws may not yet be included in the ILCS database, but they are found on this site as Public Acts soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the Guide.

Because the statute database is maintained primarily for legislative drafting purposes, statutory changes are sometimes included in the statute database before they take effect. If the source note at the end of a Section of the statutes includes a Public Act that has not yet taken effect, the version of the law that is currently in effect may have already been removed from the database and you should refer to that Public Act to see the changes made to the current law.

625 ILCS 5/15-302

    (625 ILCS 5/15-302) (from Ch. 95 1/2, par. 15-302)
    Sec. 15-302. Fees for special permits. The Department with respect to highways under its jurisdiction shall collect a fee from the applicant for the issuance of a permit to operate or move a vehicle or combination of vehicles or load as authorized in Section 15-301. The charge for each permit shall consist of:
        1. a service charge for special handling of a permit
    
when requested by an applicant;
        2. fees for any dimension, axle weight or gross
    
weight in excess of the maximum size or weight specified in this Chapter; and
        3. additional fees for special investigations as in
    
Section 15-311 and special police escort as in Section 15-312 when required.
    With respect to overweight fees, the charge shall be sufficient to compensate in part for the cost of the extra wear and tear on the mileage of highways over which the load is to be moved. With respect to over-dimension permits, the fee shall be sufficient to compensate in part for the special privilege of transporting oversize vehicle or vehicle combination and load and to compensate in part for the economic loss of operators of vehicles in regular operation due to inconvenience occasioned by the oversize movements.
    Fees to be paid by the applicant are to be at the rates specified in this Chapter. In determining the fees in Section 15-306 and paragraph (f) of Section 15-307, all weights shall be to the next highest 1,000 pounds and all distances shall be determined from the Illinois Official Highway Map.
    For repeated moves of like objects which cannot be dismantled or disassembled and which are monolithically structured for permanent use in the transported form, the fees specified in Sections 15-305, 15-306 and 15-307 for other than the first move shall be reduced by $4 provided the objects are to be moved from the same origin to the same destination, the number of trips will not be less than 5, the trips will be completed within 30 days, and all applications are submitted at one time. Round trip permits shall be the same as a single trip permit except the fee shall be computed based upon the total distance traveled, and shall be for the same vehicle, vehicle combination or like load traveling both directions over the same route, provided a description including make and model of the equipment being transported is furnished to the Department. Limited continuous operation permits are to be valid for a period of 90 days or one year, and shall be for the same vehicle, vehicle combination or like load.

    (a) Except as provided in subsection (g), local authorities with respect to highways under their jurisdiction may by ordinance or resolution prohibit the operation of vehicles upon any such highway or impose restrictions as to the weight of vehicles to be operated upon any such highway, for a total period of not to exceed 90 days, measured in either consecutive or nonconsecutive days at the discretion of local authorities, in any one calendar year, whenever any said highway by reason of deterioration, rain, snow, or other climate conditions will be seriously damaged or destroyed unless the use of vehicles thereon is prohibited or the permissible weights thereof reduced.
    (b) The local authority enacting any such ordinance or resolution shall erect or cause to be erected and maintained signs designating the provision of the ordinance or resolution at each end of that portion of any highway affected thereby, and the ordinance or resolution shall not be effective unless and until such signs are erected and maintained. To be effective, an ordinance or resolution passed to designate a Class II roadway need not require that signs be erected, but the designation shall be reported to the Department.
    (c) Local authorities with respect to highways under their jurisdiction may also, by ordinance or resolution, prohibit the operation of trucks or other commercial vehicles, or may impose limitations as the weight thereof, on designated highways, which prohibitions and limitations shall be designated by appropriate signs placed on such highways.
    (c-1) (Blank).
    (c-5) Highway commissioners, with respect to roads under their authority, may not permanently post a road or portion thereof at a reduced weight limit unless the decision to do so is made in accordance with Section 6-201.22 of the Illinois Highway Code.
    (d) The Department shall likewise have authority as hereinbefore granted to local authorities to determine by resolution and to impose restrictions as to the weight of vehicles operated upon any highway under the jurisdiction of said department, and such restrictions shall be effective when signs giving notice thereof are erected upon the highway or portion of any highway affected by such resolution.
    (d-1) (Blank).
    (d-2) (Blank).
    (e) When any vehicle is operated in violation of this Section, the owner or driver of the vehicle shall be deemed guilty of a violation and either the owner or the driver of the vehicle may be prosecuted for the violation. Any person, firm, or corporation convicted of violating this Section shall be fined $50 for any weight exceeding the posted limit up to the axle or gross weight limit allowed a vehicle as provided for in subsections (a) or (b) of Section 15-111 and $75 per every 500 pounds or fraction thereof for any weight exceeding that which is provided for in subsections (a) or (b) of Section 15-111.
    (f) A municipality is authorized to enforce a county weight limit ordinance applying to county highways within its corporate limits and is entitled to the proceeds of any fines collected from the enforcement.
    (g) An ordinance or resolution enacted by a county or township pursuant to subsection (a) of this Section shall not apply to cargo tank vehicles with two or three permanent axles when delivering propane for emergency heating purposes if the cargo tank is loaded at no more than 50 percent capacity, the gross vehicle weight of the vehicle does not exceed 32,000 pounds, and the driver of the cargo tank vehicle notifies the appropriate agency or agencies with jurisdiction over the highway before driving the vehicle on the highway pursuant to this subsection. The cargo tank vehicle must have an operating gauge on the cargo tank which indicates the amount of propane as a percent of capacity of the cargo tank. The cargo tank must have the capacity displayed on the cargo tank, or documentation of the capacity of the cargo tank must be available in the vehicle. For the purposes of this subsection, propane weighs 4.2 pounds per gallon. This subsection does not apply to municipalities. Nothing in this subsection shall allow cargo tank vehicles to cross bridges with posted weight restrictions if the vehicle exceeds the posted weight limit.

    Sec. 15-317. Special weight limitation on elevated structures.
    (a) No person shall operate a vehicle or combination of vehicles over a bridge or other elevated structure constituting a part of a highway with a gross weight which is greater than the maximum weight permitted by the Department, when such structure is sign posted as provided in this Section.
    (b) The Department upon request from any local authority shall, or upon its own initiative may, conduct an investigation of any bridge or other elevated structure constituting a part of a highway, and if it finds that such structure cannot with safety to itself withstand the weight of vehicles otherwise permissible under this Chapter the Department shall determine and declare the maximum weight of vehicles which such structure can withstand, and shall cause or permit suitable signs stating maximum weight to be erected and maintained before each end of such structure.
    (c) Upon the trial of any person charged with a violation of this Section proof of the determination of the maximum allowable weight by the Department and the existence of the signs, constitutes conclusive evidence of the maximum weight which can be maintained with safety to such bridge or structure.
