Does My Vehicle Need to be Tested?

If your vehicle is due for testing and your plates are expired, please test at your earliest convenience.  Waiting until the end of October, when the SOS registration extensions are expected to end, could result in heavy traffic and long wait times.

For a list of Illinois Air Team testing locations, please visit the Testing Station Locator.

Motorists can find out when their vehicle is due for an emissions test by entering the VIN or license plate number into our Vehicle Eligibility Check tool.

Test Eligibility Guidelines:

  • Most 1996 and newer gasoline-powered passenger vehicles are subject to testing after they are four years old (e.g., 2012 vehicles are being tested in 2016 for the first time).
  • The testing month coincides with the expiration date of the vehicle license plate.
  • Typically, even model-year vehicles are tested during even years and odd model-year vehicles are tested in odd years.

If you have any questions, please contact the Illinois Air Team at 844.258.9071.
