If you are on active duty outside Illinois, you and your dependents can keep driving on an expired Illinois license for up to 120 days after you come back to the state. You have to carry a Military Deferral Certificate with the expired license. The certificate is free and is mailed to your out-of-state address.
Send a copy of your current Illinois driver’s license, a copy of the front and back of your military ID card, and your out-of-state address to Secretary of State, License and Medical Review Unit, 2701 S. Dirksen Parkway, Springfield, IL 62723, or email militarydeferral@ilsos.gov. For questions, call 217-782-2720.
