NOTE: Illinois EPA resumed mailing vehicle emissions test notices beginning April 6, 2016. Test notices will be retroactive to the first motorists that did not receive a test notice (vehicle owners whose license plates expired at the end of March 2016). Motorists who have completed testing requirements will not receive one of the new test notices.
**Effective April 2016, vehicle emissions test notices will be mailed on a postcard size form.
As a result, Illinois Secretary of State Jesse White announced his office will resume regular vehicle registration procedures effective June 1, 2016. At that time, motorists subject to vehicle emissions testing will once again be required to comply with testing requirements prior to renewing their license plates.
Illinois EPA urges motorists to have their vehicles tested several weeks prior to the license plate expiration to allow sufficient time to test the vehicle, and when necessary, perform repairs.
Motorists can find out when their vehicle is due for an emissions test by entering the vehicle's VIN number or license plate number into this Vehicle Eligibility Check tool.
The Illinois Secretary of State also has an online tool to determine whether a vehicle is due for emissions testing.
Please note that while the vehicle may be tested up to four months prior to license plate expiration, the plate may only be renewed within three months of the expiration date.
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.
No. Technicians at the station are able to test the vehicle without a notice. If you have receive a test notice, you may bring it to the station.

No, the test event is automatically recorded on the Illinois EPA database and transmitted to the Secretary of State.
