All Vehicle Emissions Testing Stations will be closed on Friday, February 12 th and Monday, February 15 th in observance of Lincoln's Birthday and Presidents Day.
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.
As a result, Illinois Secretary of State Jesse White announced that he will temporarily allow license plate renewals for vehicle owners who have not yet passed the EPA emissions test. Beginning March 1, motorists may renew their license plates, but will be informed they are still required to get the vehicle tested.
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.

Illinois EPA Vehicle Emissions Testing Program Changes
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:
- Pre-2007 model year gasoline-powered vehicles with a manufacturer's gross vehicle weight rating (GVWR) between 8,501 and 14,000 pounds.
- All gasoline-powered vehicles with a manufacturer's GVWR greater than 14,000 pounds (regardless of model year).
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.
Tips for a successful test:
- Have your vehicle timely tested.
- Avoid testing at the end of the month and on Saturdays, since these are the busiest testing times.
- Check this web site for station locations, maps, and operating hours. Stations are closed on Sundays and State Holidays.
- Make sure the vehicle brought in for testing is due for testing. The Illinois Secretary of State has an online tool to determine whether a vehicle is due for emissions testing.
- Ensure your vehicle is safe to operate so that your emissions test may be safely conducted.
- Please drive your vehicle for at least 15 minutes prior to entering the test station to ensure that your vehicle is adequately warmed-up for the inspection.
- If your 1996 or newer OBD-equipped vehicle has a covered or otherwise obstructed diagnostic link connector (DLC), please open or remove the cover (consult owner's manual for location and instructions), or remove the obstruction prior to arriving at the test station.
- If your 1996 or newer OBD-equipped vehicle has recently been serviced, or if the battery has been disconnected, please drive the vehicle for several days before bringing it in for inspection.
- When arriving at a test station, leave the engine running unless directed otherwise.
