How to tell if your vehicle needs an emissions test

To see if your vehicle needs an emissions test, check your tab renewal notice or email reminder. If it says “This vehicle must pass a Washington emission inspection,” the vehicle must be tested before you can renew your tabs.

Requirements for military personnel

If you drive on a military base within an emission inspection area for more than 60 days a year, federal law requires your vehicle to be emission tested regardless of where they’re registered. Any questions about these requirements should be referred to your military base.

Exempt vehicles

The following types of vehicles are exempt from emission testing requirements:

• Certain hybrid vehicles that have an efficiency rating of at least 50 miles per gallon for city driving.
• 2009 and newer passenger cars, SUVs, vans, and pickup trucks that are certified to California emission standards.

How to renew your tabs after the test

When your emissions test is complete, the testing station will send us your results electronically. In most cases, our records should show your vehicle passed the emissions test within 2 hours of its completion.

• If you renew your tabs online, you should be able to renew your tabs as soon as the emission results are updated in our records. Please allow a few hours after your vehicle passes the emissions test before renewing your tabs online.
• If you renew at an office, our records should show your vehicle passed the emission test by the time you arrive. However, we recommend bringing along a copy of your test results just in case you arrive at the office before this automated update is complete.
