The Illinois Transportation Order (ITO) is a type of document issued by the Illinois Department of Transportation (DOT). It is used to provide authorization for the shipment of goods and services over the highways and waterways of the state. It serves as a legal document that allows shippers to move goods safely and efficiently throughout the state. The ITO is issued to both in-state and out-of-state companies who are authorized to transport goods within the state. There are two types of Illinois Transportation Orders: Interim and Permanent. An Interim ITO is valid for one year and is only issued to companies authorized to transport hazardous materials. A Permanent ITO is valid for three years and is issued to companies authorized to transport general freight. Both types of ITO require the shipper to provide proof of insurance and safety equipment, as well as provide documentation of the route and type of cargo being transported.
