IDOT is authorized by the Illinois Vehicle Code (625 ILCS 5/15 – 301) and the 92 Illinois Administrative Code 554, Sub-chapter F, with respect to highways under its jurisdiction that IDOT may, at their discretion, upon application and good cause being shown therefore, issue special permits 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 Act or otherwise not in conformity with this Act upon any highway under the jurisdiction of the state of Illinois. An Oversize/Overweight permit is required, when a vehicle or load exceeds legal sizes and weights, and is to be moved upon or across a highway for which the state is responsible. Permit applications are reviewed for bridge tolerances, construction zones, height clearance and several other safety concerns. The new Illinois Transportation Automated Permit system (ITAP) system allows customers to go online and apply. Most permits are immediately issued. Oftentimes, in order to complete your move, roads NOT authorized to be permitted by IDOT may be necessary. In all such cases involving local jurisdiction roads, permittees MUST obtain permission from appropriate local authorities prior to movement.
