Truckers and Suppliers
Federal law requires that IDOT maintain a list of all firms that bid or quote on federal-aid contracts. Illinois Administrative Code extends this to all Department contracts regardless of funding..
Trucker / Supplier Registration
Per federal law all truckers/suppliers are required to register with IDOT in order to bid or quote on subcontracts to federal-aid contracts. Illinois Administrative Code extends this to all Department contracts regardless of funding.
Truckers / Suppliers can register online via the Trucker / Supplier Registration Form. The registration form requires minimal information and can be completed in minutes. Confirmation, along with a registration number, will be received via email in one to two days. Registration is valid for one year and will require renewal.
Approximately one month prior to expiration, a notice to renew and instructions will be sent via email. If a Trucker / Supplier does not have a valid email address, a notice will be sent via postal mail. Truckers / Suppliers can renew their registration on line via the Trucker / Supplier Update Form.
If a revision is required at any time, please do not register again. Revisions can be made by submitting a Trucker / Supplier Update Form or by calling a department representative.

Partnering with Primes
The Transportation Bulletin details the projects being advertised. Truckers / Suppliers must deal directly with the prime contractors that are authorized to bid on a project. There are two ways to communicate with the prime contractor to express interest.
- The For Bid List of Bidders can be used to contact authorized prime contractors to offer a quote for their portion of the work.
Note: The first version of this list is posted two weeks following the posting of the Notice of Letting Bulletin. It is then updated each Friday and on the day before the letting.
- The Industry Marketplace can be used to provide quotes on certain jobs at the request of prime contractors.
It is the responsibility of subcontractors and suppliers on IDOT highway construction projects to collect monies that are owed to them by the prime contractor. IDOT is unable to make payments to anyone other than the prime contractor, so you must protect yourself from nonpayment or collection problems.
Navigate to Lien and Bond Claims for more information.
Subcontractors are required to follow the specs, policies, and manuals to complete the work.
Interested in the DBE Program?
IDOT strives to maintain an equitable distribution of work for its many business partners. One way to accomplish this is through the department’s administration of the federally mandated DBE Program. The DBE program is intended to provide contracting opportunities to small businesses owned and controlled by socially and economically disadvantaged individuals. On most projects a DBE percentage goal is required.
To view the directory of DBE firms that are certified please view the IL UCP (updated every month).
