If determined that the truck is overweight the officer will charge the driver accordingly and assess the appropriate fine amount set under 625 ILCS 5/15-111. Any person who refuses or fails to stop and submit his or her vehicle and load after being directed to do so by an authorized agent of the city, or who removes or causes the removal of any portion of the load prior to weighing, shall be fined not less than five hundred dollars ($500) and not more than two thousand dollars ($2,000).
Overweight Fines are incremental; the fine for the first 2000 pounds overweight is $73. The fines increase with every additional 500 pounds up to 24,000 pounds overweight, for which the fine is $3,975. More than 24,000 lb overweight, the fine increases an additional $75 for each increment of 500 lb.

The Illinois DOT has the authority to issue special permits with respect to highways under its jurisdiction for loads that cannot be reasonably dismantled or disassembled or are otherwise non-divisible. The permits may be issued as single-trip permits or for limited continuous operation (annual permits) and must indicate on which routes the vehicle may travel.
Permitted vehicles are allowed a scale tolerance of up to 2,000 lbs. on a single axle, 3,000 lbs. on a tandem axle, and 5,000 lbs. gross weight above the permitted limits.

This discretional authority is limited to shipments of livestock, hazardous materials, liquid concrete in a mobile cement mixer, or hot asphalt (Ill Rev. Stat. ch. 625, §5/15-301[l]).
