Oregon's DEQ Too™ Program
Terms and Conditions for Motorist

(Version 3/5/2016)

DEQ Too™ is a program of the Oregon Department of Environmental Quality (DEQ) that provides another option for an Oregon motorist to take care of their DEQ vehicle emissions test. It's completely voluntary to use this option instead of visiting a DEQ Clean Air Station for the test. The DEQ Too test is conducted through a telematics device that transmits the vehicle's onboard diagnostics (OBD) data to DEQ to determine the results of the emissions test. Using a DEQ Too Business Participant, motorists will either borrow a telematics device for a couple of minutes or use one longer-term. Please see our Frequently Asked Questions for further details on telematics devices and DEQ Too Business Participants.

After using the telematics device, the motorist then reviews the test results on this website. If DEQ determines that the motorist has passed the emissions test, the motorist may purchase an E-Certificate on this website and then renew the vehicle's registration on the website of DMV (Driver and Motor Vehicle Services Division of the Oregon Department of Transportation). Under the DEQ Too Program, the motorist must conduct both the DEQ certification and the DMV registration renewal online.

By using the Oregon DEQ Too program website, I agree to the following terms and conditions:

  1. These are the Current Terms and Conditions. I understand the following: DEQ may modify these terms and conditions from time to time. Each time I check my vehicle test results on this website, it is important that I carefully read through these terms and conditions. My continued use of the Oregon DEQ Too program website after any modification to these terms and conditions means that I agree to those terms and conditions, as they may have been modified.
  2. Answers to Frequently Asked Questions. In using this website, I understand the following: I am aware that this website has a Frequently Asked Questions section to find answers to many common questions regarding the DEQ Too program and the use of this website.
  3. DEQ Too Test Results. In using this website, I understand the following:
    • This website allows me to review the results of OBD data that I authorized to be transmitted to DEQ through a telematics device.
    • The results of a test using a telematics device are not available at a DEQ Clean Air Station.
    • The results of an emission test conducted at a DEQ Clean Air Station are not available on any DEQ website.
  4. A DEQ Too E-Certificate Only has Value for Renewing Through DMV's Online Registration System. If I elect to purchase a DEQ Too E-Certificate, I understand the following:
    • I should only purchase an E-Certificate if I intend to renew my vehicle's registration through DMV's online registration renewal system.
    • I should only purchase an E-Certificate if I am eligible to renew online with DMV and not restricted from doing so.
    • I will not be allowed to use the E-Certificate to renew my DMV registration by any other method; including, as follows:
      • An E-Certificate cannot be used to renew DMV registration at a DEQ Clean Air Station.
      • An E-Certificate cannot be used to renew DMV registration at a DMV Field Office.
      • An E-Certificate cannot be used to renew DMV registration through the mail with DMV.
    • If I determine that I do need to renew my DMV registration through one of these other methods, I understand that my vehicle must be tested at a DEQ Clean Air Station and that if I've already purchased an E-Certificate, it cannot be refunded nor can it be used as documentation for passing the test at a Clean Air Station.
  5. DMV's Online Registration Renewal System. By using DMV's online vehicle registration renewal system, I understand the following:
    • I must have a DMV online renewal access code in order to renew my registration on the DMV website. This code is found on DMV's registration renewal application form.
    • I must complete the DMV online registration renewal no later than 75 days after my vehicle's registration expiration date.
    • If for any reason I do not complete my online renewal with DMV within that timeframe, or if for any reason DMV does not allow me to renew my registration online, the DEQ Too E-Certificate I purchased no longer has value and is not refundable.
  6. DEQ Too Business Participants. I understand the following:
    • DEQ does not endorse any of the DEQ Too Business Participants over any other Business Participant in the program.
    • I should direct any questions related to the use of the transmission device or the transfer to DEQ of my vehicle's OBD data to the appropriate Business Participant.
  7. Transmission of Data from Vehicle to DEQ. I understand the following:
    • I have voluntarily authorized a DEQ Too Business Participant to electronically transmit my vehicle's OBD data to DEQ.
    • During or prior to the electronic data transmission, I did not tamper with or alter my vehicle's OBD system from its original equipment configuration (a violation of Section 203-a-3 of the Federal Clean Air Act).
    • DEQ has reviewed my vehicle's onboard diagnostics data to determine the results of my vehicle emissions test.
    • DEQ is not responsible for any errors or omissions in the data transferred by the DEQ Too Business Participant.
  8. Non-Refundable. I understand the following:
    • Once I choose to purchase a DEQ Too E-Certificate, the E-Certificate is non-refundable.
    • If I have purchased a DEQ Too E-Certificate and purchased a Certificate at a Clean Air Station for the same vehicle during the same renewal cycle, only one Certificate was necessary for me to purchase and neither Certificate is refundable.
  9. Miscellaneous. I understand the following:
    • DEQ makes no representations or warranty as to the completeness, accuracy, timeliness, or content of any data made available through this site. DEQ expressly disclaims all warranties, whether express or implied, including any implied warranties of merchantability, or fitness for a particular purpose.
