Questions about Test Notices

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.

License Plate Renewal-Based Enforcement of the Vehicle Emissions Test Program

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.

When can I come in for an emissions test?

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.

The Illinois Secretary of State 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.

Do I need a notice to get my car tested?

No. Technicians at the station are able to test the vehicle without a notice.

What should I do if my address is incorrect on my vehicle registration or I have moved?

State law requires that you notify the Secretary of State within 10 days of any change of address. As a convenience, change of address forms are available online or at emissions test stations.

After my vehicle has been tested, do I need to mail anything to the Illinois EPA or the Secretary of State?

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

If you have any other questions, please visit the Customer Service Representative at any of the vehicle emissions testing stations, call the Illinois EPA at 800-635-2380, or check this website for updates.
