New to the Oregon and DEQ?

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.

​​No, you do not need to bring any paperwork in order to have your vehicle tested. All you need to bring is the vehicle itself.

​
​Fee information can be found by following the below links.
 

​
​We have six stations in the Portland Metro area and one in the Medford/Ashland area. You can find the station closest to you by clicking on the below links.
 
Note: Vehicles new to the state are not eligible to use the DEQ Too program.
 

​​No, you do not need an appointment. Testing is first come, first served.

​
​Testing takes between five and eight minutes per vehicle.
 
  • Tuesdays and Saturdays are generally the busiest days of the week.
  • Lines are often shorter on Thursdays, Fridays and mid-month.

​
​You can see which vehicles must be test in the Portland and the Medford areas. To find out if your vehicle falls within a testing area, visit our Inspection Boundary Lookup.

​We do not inspect for functioning taillights or blinkers. We only test for emissions compliance.

​We can only perform a VIN inspection in addition to an emissions test. Motorcycles, off-road vehicles, trailers and any other vehicles not required to have an emissions test will need to have VIN inspections performed at the DMV.

​

​​​​PLEASE NOTE: For the safety of staff, the public and our furry friends, we encourage pets not to visit us when coming to a DEQ testing station. Service animals​ are welcome.​​​​​

​
​

​In most instances, you will be asked to exit the vehicle during the testing process. 

​We ask that children are not left unattended in the vehicle.

​
​The type of test your vehicle needs depends on a number of factors. Generally speaking, 1995 and older vehicles receive a tailpipe test, while 1996 and newer vehicles receive a computerized test known as an On-Board Diagnostics (OBD) test. For more information, visit our test methods page.
