Illinois EPA encourages those 65 and older, healthcare workers, first responders, and those with pre-existing health conditions to visit Illinois Air Team testing locations during the first testing hour of each day. We ask those without these special considerations to arrive at testing facilities after the first testing hour of each day.

When should I test my vehicle?

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. 

How long do I have to test my vehicle?

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.

If you do not feel comfortable visiting an Illinois Air Team testing location, you may take advantage of the registration expiration extension or you may have someone else bring your vehicle in for emissions testing. 

How can I check if my vehicle is due for an emissions test?

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. Please refer to the FAQs above: “How long do I have to test my vehicle?” and “When should I test my vehicle?

Any special considerations for the elderly, healthcare workers, first responders, individuals with compromised immune systems or chronic medical conditions?

We encourage the elderly, healthcare workers, first responders, and those with compromised immune systems or pre-existing health conditions to visit Illinois Air Team testing locations during the first testing hour of each day (8:00 – 9:00 a.m. Mondays through Fridays and 7:30 – 8:30 a.m. on Saturdays). We ask those without these special considerations to arrive at testing facilities after the first testing hour of each day.

What precautions are being taken to protect motorists and Air Team staff?

Extensive precautions are in place and follow Illinois Department of Public Health COVID-19 Workplace Guidelines to protect motorists and our staff. Illinois Air Team staff will:

  • Wear face masks at all times
  • Practice social distancing protocols
  • Clean and disinfect stations regularly
  • Minimize contact with vehicles

What precautions can I take to help with safety during the pandemic?

Customers are asked to abide by the following: 

  • One person per vehicle and no pets or passengers
  • Wear masks to be served
  • Practice social distancing
  • Follow Air Team testing location directions regarding maintaining social distancing

Can someone else bring my vehicle in for an emissions test?

The registered owner does not have to bring their vehicle in to be tested.  We strongly suggest those individuals with compromised immune systems or chronic medical conditions have someone else bring the vehicle in to be tested or take advantage of the registration expiration extension in place.

What changes in testing procedures will I notice?

  • Motorists will be asked to provide vehicle mileage verbally
  • Motorists will wait in designated areas outside of waiting booths for motorist safety and to maintain social distancing during emissions tests
  • All passengers will be asked to exit the vehicle and wait in designated areas while wearing a mask to maintain social distancing during the test, but motorists are asked to not bring passengers with them
  • Staff will make every attempt not to touch your vehicle except to connect and disconnect test equipment
  • Staff will ask if you wish to receive a paper copy of your test results

Do I have to take a copy of my test results?

To minimize contact, motorists are not required to take a copy of their test results.  Passing test results are transmitted to SOS automatically and electronically. Documents can be placed in the vehicle without contact if desired.  There will also be an option to take a photo of testing documents with your phone.  Receiving a paper copy of passing test results is not necessary to renew your registration.

Will the police ticket me for an expired registration?

The Secretary of State Police has notified Illinois law enforcement and law enforcement agencies across the country of the registration expiration extension. The Secretary of State has encouraged police departments across the state not to write tickets.

Do I have to pass the test before I can renew my vehicle registration?

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 can be renewed.

Can I purchase my vehicle sticker at the testing stations?

Vehicle stickers are sold in the office at all centralized testing facilities.  Extensive precautions are in place and follow Illinois Department of Public Health COVID-19 Workplace Guidelines to protect motorists and our staff.

Why do I have to get an emissions test?

The Illinois EPA's vehicle emissions testing program (I/M Program) plays an important role in improving air quality and public health in Illinois. Motor vehicle exhaust emissions are a significant source of pollution, including carbon monoxide, nitrogen oxides and hydrocarbons. These pollutants can be harmful to human health and the environment and lead to the formation of ground level ozone (smog). Exhaust emissions from cars and trucks are one of the single greatest sources of air pollution in the Chicago and Metro-East St. Louis areas. 

The I/M Program is a federal and State mandate in the Chicago and Metro-East St. Louis areas because these areas do not meet the National Ambient Air Quality Standards (NAAQS) for ozone. The I/M Program helps reduce air pollution from motor vehicles in these areas of Illinois and is part of Illinois EPA’s strategy to reduce air pollution in Illinois and bring the Chicago and Metro-East areas into attainment of the ozone NAAQS.
