Emissions Testing in Seattle, WA

The State of Washington operates a vehicle emissions check program that requires the testing of vehicles within certain areas, including Seattle, WA. Residents have up to 30 days to register their vehicle when moving to the area. Their vehicle must pass the emissions test before registration will be allowed. Renewing your tabs will also require a renewal of your emissions inspection certification unless your vehicle has been classified as being exempt.

Where Are Emissions Tests Required in WA?

There are 5 counties in the State of Washington which require emissions inspections on all new and renewal registrations for non-exempt vehicles: Clark, King, Pierce, Snohomish, and Spokane. That means if you live in the Seattle-Tacoma-Bellevue, WA Metropolitan Area, there is a good chance your vehicle may require an emissions test. These tests are required every two years. You will be notified that your vehicle is due for the test through your renewal notice. Within these 5 counties, however, there are certain ZIP codes that are exempt from the emissions testing. You can reference the updated emission check area to determine if your vehicle is registered within an exempt ZIP code.

What Is the Emissions Standard in WA?

In the State of Washington, all vehicles within a designated area, without a waiver, must meet current California emissions standards. This is because of the Clean Car Law in the state. It is set to expire in 2019, though vehicles must still meet the expectations of the law until it fully expires. Certain vehicles receive an automatic waiver from the inspection. Hybrid vehicles, diesel vehicles under 6,001 pounds or with a model year 2007 or newer, as well as vehicles built in 2009 or newer, do not require emissions testing. If you purchased your brand-new vehicle from a Washington dealer, you may not be required to have the vehicle tested either.

Vehicles that are over 25 years old are exempt from the emissions testing laws as well, including in the Seattle metro area. If you own a vehicle that has been designated a “collectible,” you may need to apply for certification of that status for the vehicle to be exempt from emissions testing.
