90 day grace period to help reduce extremely long wait times.
Emissions testing resumed June 1, 2020 at most Illinois Air Team testing locations. To help motorists deal with the COVID-19 pandemic, vehicle registration expiration dates have been extended without penalty for at least 90 days. In order to reduce traffic volume at stations and reduce motorist wait times, please choose to postpone testing to a later date given construction in the area is also causing long wait times. It is recommended that only motorists with an expiration date of March or earlier should have their vehicles tested in June.
