Naperville Emissions Testing and Diagnosis – Pass the Vehicle Emission Test

We make passing your emissions test easy and convenient!

A car bought brand new does not need to be tested for four years. Then its every two years at the end of the month your plate sticker is due.

Police can ticket cars driving or parked if they see a sticker past due. You can call us and we can run your plate to get the history of tests and when the car is due next.

We do the most emissions with 100% in a 15 mile radius. 100 percent success rate according to Illinois Vehicle Inspection Report.

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 call the Illinois EPA at (847) 758-3400 or (800) 635-2380
