The Washington state knowledge test is a 40-question multiple-choice exam given by the Department of Licensing (DOL) to anyone applying for a first instruction permit or driver license. You need 32 correct answers, an 80% score, to pass, and every question comes from the official Washington Driver Guide. A passing score stays on your record for two years.1Washington State Department of Licensing. Do I Need to Take a Test?
Who Has to Take It
Anyone applying for their first Washington driver license or instruction permit with no prior license history must pass the knowledge test.1Washington State Department of Licensing. Do I Need to Take a Test? That covers teens entering the graduated licensing system and adults who never held a license anywhere. Even if you already hold a Washington instruction permit, a passing score has to be on file before you can move on to the drive test.
If you’re transferring a valid license from another U.S. state, the rule is different. You have 30 days after moving to get a Washington license, and the DOL says you must “pass any required driver tests” at the licensing office.2Washington State Department of Licensing. Moving to Washington: Get a Driver License The agency doesn’t publish a clear list of which transfers trigger the knowledge test, so call your local office before your appointment to confirm.
Age Requirements
You can apply for an instruction permit at 15 if you’re enrolled in an approved traffic safety education course that includes practice driving. Without that enrollment, you have to be at least 15 and a half.3Washington State Legislature. RCW 46.20.055 – Instruction Permit At 18 or older, there’s no enrollment requirement. Most teens end up taking the knowledge test through the driving school they’re already attending.
Before You Can Schedule
You need a Washington driver license number before booking the test. The DOL assigns one when you pre-apply online through the License Express portal. The number starts with “WDL” and is what you’ll use when you schedule.4Washington State Department of Licensing. Pre-Apply Online
The pre-application asks for your Social Security number, physical descriptors, and contact information. If you want a REAL ID–compliant credential such as an Enhanced Driver License, you’ll also need proof of U.S. citizenship, proof of identity, and proof of Washington residency.5Washington State Department of Licensing. REAL ID Identity documents commonly include a birth certificate or passport; residency is usually shown with utility bills, bank statements, or similar mail carrying your Washington address. Fill everything out online before your appointment so your file is active when you arrive.
What the Test Covers
All 40 questions come from the Washington Driver Guide. The exam leans on road signs, pavement markings, and signal lights. Expect right-of-way questions involving pedestrians and cyclists, safe following distances in different weather, and how to handle school buses, emergency vehicles, and four-way stops.
Impaired driving comes up repeatedly. Washington’s implied consent law, the consequences of driving under the influence, and reckless-driving penalties are regular topics. The Move Over law is on the test too, which requires drivers to change lanes or slow down when passing emergency zones and carries a minimum $250 penalty that cannot be reduced or waived.6Washington State Legislature. RCW 46.61.212 – Emergency or Work Zones Approaching Penalty Violation

Languages and Accommodations
The knowledge test is offered in 12 languages: English, Spanish, Traditional Chinese, Simplified Chinese, Korean, Russian, Vietnamese, Japanese, Arabic, Punjabi, Tagalog, and Ukrainian.1Washington State Department of Licensing.

If you need an accommodation such as headphones or an audio-assistive device, call the DOL at 360-902-3900 or visit a community-based licensing office to talk through your needs. Staff will work with you when you check in, though the DOL notes that some accommodations may be limited by state or federal regulations.7Washington State Department of Licensing.

How to Prepare
The Washington Driver Guide is the single source for every question. The DOL publishes it as a free PDF in 14 languages (the 12 testing languages plus Amharic and Hindi) and offers text-only and plain-text English versions.8Washington State Department of Licensing. Driver Guides Read the whole thing at least once before you schedule. The chapters on signs, right-of-way, and impaired driving appear most often on the test, so give those extra time.
The DOL also offers a free five-question online practice test.8Washington State Department of Licensing. Driver Guides Five questions won’t simulate the full exam, but the format and difficulty match what you’ll see. Third-party practice tests can supplement your study, though the Driver Guide remains the authoritative source.
Scheduling and Test Day
With your WDL number, you can take the knowledge test at a DOL office or any state-approved driver training school.9Washington State Department of Licensing. Driver Training Schools and Testing Locations Booking is done through the DOL’s online portal or the school’s own system. Available time slots usually appear on a calendar, and most people can find something within a few days.
Bring identification matching your pre-application information. The test runs on a touch-screen kiosk in a quiet area. The DOL doesn’t publish a time limit, but the exam rarely takes more than 20 to 30 minutes. Your score displays as soon as you answer the final question and is uploaded automatically to your DOL record.
Fees vary by location. The DOL doesn’t set a fixed statewide amount and directs applicants to check with the testing site for the exact cost.10Washington State Department of Licensing. Driver Licensing Fees Call ahead so the price isn’t a surprise.
If You Don’t Pass
Missing 32 correct means you’ll need to retake the exam. The DOL notes there may be a waiting period before a retest, and the length depends on the location.1Washington State Department of Licensing. Do I Need to Take a Test? Some sites can fit you in the same day when a slot opens; others require a new appointment days out. Retakes typically require paying the fee again, so check your testing site’s specific policy.
If you’ve failed more than once, don’t just book another attempt. Go back to the Driver Guide and focus on the sections tied to the questions you missed. The question pool is large, so trying to memorize answers from a previous try won’t get you far.
After You Pass
A passing score is valid for two years.1Washington State Department of Licensing. Do I Need to Take a Test? Inside that window you’ll need to get your instruction permit and eventually pass the drive test. If the score expires first, you’ll retake the knowledge test.
You can get your permit at a DOL office in person or through the License Express website. The permit costs $35 for a one-year term.10Washington State Department of Licensing. Driver Licensing Fees You’ll receive a paper permit immediately, and a plastic card arrives by mail in about two to three weeks. Applicants under 18 must bring a parent or guardian listed on their birth certificate, along with that parent’s Washington license or U.S. passport.
