Vehicle Registration and Tag Renewal
License Plate Renewal-Based Enforcement of the Vehicle Emissions Testing 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’s registration (license plates) can be renewed. A Test Notice is mailed up to four (4) months prior to your vehicle’s license plate expiration to remind you to take your vehicle in for an emissions test.
The Secretary of State’s Office mails License Plate Renewal Notices that include a statement as to whether compliance with the Vehicle Emissions Inspection Law is required before a vehicle’s registration can be renewed. The Secretary of State’s Office sends 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.
To determine if your vehicle is eligible for an emissions test this year, use this Vehicle Eligibility Check.
* Remember, you must have your vehicle tested
before you can renew your registration.
