Personal vehicle emission testing

We oversaw the vehicle emission testing program in Washington, which ended Jan. 1, 2020. With the end of the program, vehicle owners are no longer required to have their vehicle’s emissions tested before renewing their registration.

If you have questions about renewing your vehicle registration, call the Washington Department of Licensing at 360-902-3770 or read about how to renew your tabs online.

After 38 years, Washington's emission testing program ended Jan. 1, 2020. An emissions test is no longer required before renewing your registration. Driving a vehicle with modified emissions equipment or a vehicle that smokes is illegal in Washington.
