You need a "Real ID" which can be gotten at the Secretary of State facilities, or a current passport.

The Secretary of State's office mails a renewal letter to driver's license holders 60 to 90 days prior to the expiration of your license. The letter is mailed to the address our office has on file for the driving record. The letter contains the information needed to renew your license. Testing requirements and fees vary depending on the type of license being renewed. Applicants will leave the facility with a temporary, secure paper driver's license or State ID, which is valid for 90 days and will serve as their DL/state ID for driving purposes and proof of identification. The temporary, secure paper driver's license will contain a photo and the basic information that appears on the permanent driver's license or State ID. In addition, the facility employee will return the old DL/State ID back to the applicant. https://www.cyberdriveillinois.com/departments/drivers/drivers_license/drlicid.html#dlrenew
