New to the Oregon and DEQ?

Notice: On Friday, July 3, Oregon Driver and Motor Services’ computer system will be down as it undergoes an upgrade. DEQ’s clean air stations will continue conducting emissions testing and providing certificates. However, customers cannot renew their registration or tags until DMV’s system is back online Monday, July 6. Then, customers can renew their registration and tags at DMV2U or at a DMV Express Kiosk. For more information, please see the DMV press release.

​​

Those who are new to Oregon may have questions about DEQ’s Vehicle Inspection Program. Vehicles registered in the Portland Metro and Medford/Ashland area are required to pass an emissions test in order to register a vehicle. Then, the vehicle must be tested again every two years before the registration can be renewed.
