625 ILCS 5/15-302
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:
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.
