For some zip codes, Washington State law requires vehicle emission tests to meet Federal air quality standards. See emission test area zip code. It is illegal to register your motor vehicle outside the zip code of your primary residential address.

When to Test for Emissions:.

Renewals: Motor vehicles listed in the table below must be tested.

These model year vehicles require tests during years 2015 through 2018:
1991-1995 odd model years + 1996-2008 even model years
1992-1994 even model years + 1997-2007 odd model years
1993-1995 odd model years + 1996-2008 even model years
1994         even model years + 1997-2007 odd model years

Transfer of Ownership: An emission test, passed within the last 12 months, is required to transfer vehicle ownership. Search for test record. Dealer sales are exempt from testing. The Department of Licensing cannot accept emission tests from other states.

Contact us for help in transferring ownership of inoperable vehicles.

Exceptions: Vehicles year model 2009 and newer and older than 25 years need not be tested.

You may apply for a temporary exemption if your vehicle is out of the emission testing area for an extended period of time. See out-of-area form.

An emission test costs $15.00 and can be paid by cash, check or credit card.

Diesel Vehicle Owners: These diesel vehicles do not require and emission test:

* All diesel powered vehicles weighing less than 6001 pounds

* All diesel vehicles model year 2007 and newer, regardless of weight.

If your diesel vehicle renewal notice incorrectly states you need an emission test, please contact us to remove the emission test requirement.
