Smog & Emission Checks in OregonPage Overview
Although sometimes considered a nuisance, emissions testing for vehicles is critical to improving and maintaining clean air in Oregon, a state known for its incredible natural beauty.
Information about how to obtain a Department of Environmental Quality (DEQ) emissions test, how much it costs, and steps to take in the case of failure is all available at the Oregon DEQ website.
The DEQ operates seven Clean Air Stations in the Portland and Medford, or Rogue Valley areas. You may also visit the Oregon DEQ's website to check lane lines at various stations via Webcam.
Clean Air Station hours and directions are also available online, and while the Rogue Valley location is open for business Monday through Friday, Portland locations are closed on Mondays and open Tuesday - Friday. However, these Portland locations are also open later, until 7 p.m., on Wednesdays. If you are unsure whether your vehicle requires testing, check, the DEQ website.
Before taking a DEQ emissions test, the Oregon DMV advises you to ensure the following:
- Vehicle is in good working condition
- Emissions equipment is functioning and intact
- Vehicle is not smoking
- Drive sufficiently before the test to get engine at normal operating temperature
- Leave engine running with vehicle in neutral or park during test
- Pets are left at home
- Refrain from smoking and cell phone use while in line for DEQ testing
- Vehicle models 1996 and newer with on-board diagnostics (OBD) are in "Ready" status
- You have appropriate fees: DEQ emissions testing in Portland is $21 and testing in the Medford, or Rogue Valley area is $10
There is no charge for the test if the vehicle does not pass. However, this DEQ test may be required for registration, which can also be done at DEQ testing stations if the vehicle passes.
DEQ accepts cash, money orders and credit and debit cards (VISA, MasterCard, Discover) ONLY. Once your vehicle passes inspection and you register it, you don't have to repeat the testing for two years.
Unfortunately, Oregon does not offer repair waivers for vehicles that require expensive repairs to pass the test. However, the state does offer a program to help low-income drivers pay for necessary repairs after their 1996 or newer automobile has failed the OBD test.
If your car is in the state of Oregon, you cannot get an extension on your emissions test. However, if the car is out of the state, you can call (971) 673-1640 to determine if testing is required in the location in which the vehicle resides.
If you witness a vehicle that is blatantly violating emissions laws, record the license plate, model, and make of the vehicle. Then call the DEQ at (888) 997-7888 to report the gross polluter, or file a report online.Local Smog Check Stations
