NOTE: Illinois EPA suspended the mailing of vehicle emissions test notices beginning in December 2015. Therefore, vehicle owners whose license plates expire at the end of March 2016 will be the first motorists who will not receive the vehicle emissions test notices.
Vehicles must pass an emissions test or otherwise comply with the Illinois Vehicle Emissions Inspection Law of 2005 (625 ILCS 5/13C) (“Inspection Law”) before the vehicle’ registration (license plates) can be renewed.
The Secretary of State’s office does send paperless License Plate Renewal Notices via email to individuals who register at https://www.ilsos.gov/greenmail. Electronic notices do include a statement as to whether compliance with the Vehicle Emissions Inspection Law is required before a vehicle's registration can be renewed.
If you have any questions, please call the Illinois EPA at (847) 758-3400 or (800) 635-2380.
