If you recently purchased a vehicle, it will need to be registered and titled. Please see DMV Registration for more details.
If your vehicle is new (the model year is within the last four years), it is exempt from the testing requirements.
If your vehicle is beyond the four-year exemption, please review DEQ's Testing Requirements page and Testing Options page. No paperwork from the vehicle purchase or from the DMV is required for this initial test.
DEQ does not require emissions testing of newer model year vehicles because they typically have lower mileage and are therefore less likely to experience problems with their emissions control systems.
During calendar year 2024, the following model years qualify as a “Newer Model Year Vehicle"
