Wisconsin accepts out-of-state emissions tests.
Counties with required testing
If the county where your vehicle is kept provides
OBDII emission testing, you can have your vehicle tested out-of-state. Send a copy of the passed test results, along with your renewal payment, to the address listed below. Include the address where you want your sticker and registration mailed.
You may submit a copy of the results by:
- Emailing a copy of the results to Wisconsin@OpusInspection.com
- Faxing a copy of the results to (262) 641-5095
- Mailing a copy of the results (with or without your renewal) to:
Wisconsin Department of Transportation
P.O. Box 7911
Madison, WI 53707-7911
Please include your name and phone number in case we have any issues processing your results. Once we process the results, you will be able to renew your plates.
Counties without required testing
If the county where your vehicle is kept
does not offer
OBDII emission testing, you may request a temporary exemption for the emission test. You must still renew your plate. To request a temporary exemption,
email the Wisconsin DMV, provide the state and county in which the vehicle is temporarily kept, and the date the vehicle will be back in Wisconsin and available for testing. After the temporary exemption is granted, you will be able to
renew your plate.
