What to prepare prior to the Knowledge Test?

1. Pre-apply on the WA DOL website 

If you don't have a Washington State ID card, Instruction Permit, or expired WA Driver's License, you must complete the pre-apply process on the DOL website before scheduling your Knowledge Test. It's free and saves you a trip to the DOL office. After pre-applying, you'll get a "WDL" confirmation number (e.g. WDL123456abc) required for the Knowledge Test. If you have trouble completing your pre-apply, please contact the DOL office.

If you already have a Washington State ID, Instruction Permit, or an expired WA Driver's License, you can skip the pre-apply process.

2. Study the Washington State Driver Guide

Before your Knowledge Test, make sure to study the fundamental rules of safe driving in Washington State. Familiarize yourself with road signs, right of way, emergency procedures, WA state laws, and safe driving tips. This is the most effective way to pass the Knowledge Test. The official Driver Guide is available in multiple languages for your practice. 


What to bring for the Knowledge Test?

  • Your WDL number, AND

    • New format example: "WDL123456abc"

    • If you have an old WA ID issued before 2018, your WDL number will start with your last name. 

  • A government-issued photo ID for proof of identification. Accepted forms of identification include a passport, green card, or employment authorization card.



I've taken the Knowledge Test, what's next?

After completing the Knowledge Test, you will get your results on the same day. These scores will be uploaded to the DOL website within 24 hours. Please note that only DOL officers and driving schools will have access to view these results; the results will not be visible on your personal DOL portal.

Once you've passed the Knowledge Test, go to your
local DOL office to obtain a WA Instruction Permit
 (Learner's Permit). Instruction Permit is required for Driving Lessons and warm-up sessions.
