DEQ Testing Stations and Auto Dealer Mobile On-site Testing

Phasing out prepaid coupons

As part of the continued phase out of prepaid coupons, beginning June 30, 2022, the Oregon Department of Environmental Quality will no longer sell prepaid coupons for emission certification payment at DEQ's Clean Air Stations.

To assist coupon users with this transition, Vehicle Inspection Program, will continue to accept or refund coupons already in circulation through Dec. 31, 2022.

Why phase out prepaid coupons?

Due to a significant decline in the use of prepaid coupons, increased administrative costs and availability of re-loadable payment cards, DEQ's vehicle inspection program will continue to phase out the usage of coupons. 

​We want to provide information to help you make informed payment decisions.

We have selected some articles about loadable payment cards that explain how they work and where you may obtain them. We encourage you to consult your financial institution for additional information. Every business needs to evaluate which retailers and banks will best meet their needs.

Additional option 

Dealerships, repair shops and fleets may also find DEQ Too helpful in meeting certification needs by using a telematics device without visiting a DEQ Clean Air Station. 


Options for mobile on-site coupons remains available for auto dealers. For more coupon information contact our Vehicle Inspection Technical Center at 971-673-1630 x 0 or email VIPInfo.
