NOTE: Illinois EPA has 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 (motorists 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.
See the Vehicle Emissions Test Notice FAQs for more information.
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.
We find that the lines at testing facilities are the longest at the end of the month, so “Don't Delay – Test Today!” Keep in mind that many motorists choose Saturdays to go to the testing facilities, so if you can, plan your test for a weekday. Remember, neglecting to test your vehicle can result in registration denial. See Test Day Tips below for ways to make your test go smoothly.
Monday through Friday 8 AM to 6 PM and Saturday 8 AM to 1 PM .
Station hours vary by location.
Stations are closed Sundays and State Holidays
The Illinois EPA is modifying the Vehicle Emissions Testing Program to have one standardized test at all Illinois Inspection and Maintenance testing facilities. This improvement to the program is expected to result in more efficient and quicker testing, since only the computer-based, On-Board Diagnostics test will be used for the vast majority of testing performed.
This change is due to the Governor signing legislation that eliminates the idle exhaust and gas cap tests after January 31, 2012. As part of this legislative change, the following vehicles will be exempt from the emissions test requirement:
Only two percent of the vehicles currently tested receive an idle and gas cap test which were designed primarily for older, carbureted vehicles. Air quality modeling performed by the Agency demonstrates that dropping these older tests, currently performed on very few vehicles, will have little effect on air quality.
