In Wisconsin, a vehicle emissions test is required for many original registrations, as well as for annual registration renewals. Renewal notices are sent annually to vehicle owners, and indicate whether and by what date an emissions test must be completed.

VEHICLES THAT REQUIRE AN EMISSIONS TEST

A car, truck, motor home or RV (recreational vehicle) requires an emissions test when:

  • The gross weight rating is 8500 pounds or lesser
  • It is driven mainly in the counties of Kenosha, Milwaukee, Ozaukee, Racine, Sheboygan, Washington or Waukesha.

VALIDITY

Emission tests are required every second year from the time of renewal of license plates. A valid test is required to reinstate a suspended registration and to complete an original vehicle registration or registration renewal. Used car dealers are required to issue a valid emissions test for any vehicle they sell. Getting an emissions test is the buyer's responsibility when the vehicle is purchased from a private owner. If the vehicle is more than 5 years old, the test must be done within 45 days of registration.

EXEMPTIONS

A vehicle is exempt from emissions testing when:

  • It is a 1996 model or older
  • It is a diesel powered vehicle
  • It is a motorcycle

EMISSIONS TESTING LOCATIONS

Any Authorized Vehicle Inspection Facility licensed by the State can test your vehicle. Look for the official sign issued by the Department of Motor Vehicles to authorized testing stations. The test standards and maximum fees will be displayed at the stations. Only select stations deal with light-duty diesel vehicles.

EMISSIONS TESTING FEES

The inspection is done free of cost.    

EMISSIONS TEST FAILURES

If your vehicle fails the emissions test, you must have the vehicle repaired and then it must pass the after repairs emissions test. The vehicle can be repaired at the station. Some stations offer discounts or "no-pass, no-pay" deals at the station owner's discretion.
If your vehicle is unable to meet the emissions standard following the necessary repair work, file a temporary extension form.
Contact the Division of Motor Vehicles Inspection testing Facility or call (414) 266-1080 or (800) 242-7510 for more information.
