How the Washington Knowledge Test Works
Washington's knowledge test is a written exam you take at a Department of Licensing (DOL) office to prove you understand traffic laws, road signs, and safe driving practices. The test has 35 questions, and you need to answer at least 28 correctly to pass — that's 80 percent. You get one attempt per visit, and if you don't pass, you can retake it the same day or come back another time.
The test is taken on a computer at the DOL office. You sit at a kiosk, read each question on the screen, and select your answer. The system tells you when ready whether you passed or failed. If you pass, you move forward in the licensing process. If you fail, you'll receive a printed score report showing which topics gave you trouble, so you know what to study before your next attempt.
Washington does not charge a separate fee for the knowledge test itself — the cost is included in your driver's license process fee, which varies depending on your age and license type. You do not need to bring study materials or notes into the testing room.

What Topics the Test Covers
Washington's knowledge test draws from the state's Driver Guide, which is the official resource for all test content. The questions cover traffic laws you'll encounter on Washington roads, including speed limits, parking rules, and when you must yield to other drivers. You'll see questions about right-of-way — who goes first at a four-way stop, how to handle a left turn across oncoming traffic, and what to do when an emergency vehicle approaches.
Road signs make up a significant portion of the test. You need to recognize and understand regulatory signs (like stop and yield), warning signs (like curves ahead or pedestrian crossing), and informational signs (like route numbers and distance markers). The test also covers safe driving practices: how to handle skids, what to do if your brakes fail, how to drive in rain or snow, and how to share the road with bicycles and pedestrians.
Washington-specific rules appear throughout — for example, the state's helmet law for motorcycles, requirements for child safety seats, and the rules around school buses. You may also encounter questions about impaired driving, distracted driving, and the consequences of traffic violations.
How to Study for the Test
Washington publishes the Driver Guide free online on the DOL website. This guide contains all the information tested on the knowledge exam, organized by topic. Reading through it systematically is the most direct way to prepare, because every question on the test comes from material in this guide.
The DOL also offers practice tests online, which let you answer sample questions under conditions similar to the real test. Taking practice tests helps you get comfortable with the computer format and identify which topics you need to review more carefully. Many people find it useful to take a practice test first to see where they stand, then focus their reading on weak areas, then take another practice test before their scheduled exam.
Some people study the guide in one sitting; others spread it over several days. There's no required study time — you study until you feel ready. If you're a non-native English speaker, the DOL offers the test in several languages, and you can request an interpreter at no extra cost when you schedule your appointment.
What to Bring and How to Schedule
You'll need to bring proof of identity and proof of your Social Security number. Acceptable documents include a passport, birth certificate, or state ID. You also need proof of Washington residency — a utility bill, lease, or bank statement with your current address works. Bring the originals or certified copies; photocopies are not accepted.
Schedule your test appointment online through the DOL website or by calling your local DOL office. You can choose a date and time that works for you. Most offices have appointments available within a few days, though busy locations may have longer waits. Arrive 10 to 15 minutes early to allow time for check-in.
You cannot bring study materials, phones, or other devices into the testing room. You can bring glasses or contacts if you need them for vision correction. If you have a documented disability that requires accommodation — such as extra time, a reader, or a screen magnifier — contact the DOL office where you plan to test at least a week in advance to arrange it.
What Happens If You Fail
If you don't reach 80 percent, you receive a score report that breaks down your performance by topic. This report shows you exactly which areas — such as road signs, right-of-way, or safe driving practices — need more study. Use this feedback to focus your next round of preparation rather than re-reading the entire guide.
You can retake the test when ready if you want — many people schedule a second appointment the same day or the next day. There's no penalty for retesting, and no additional fee. Some people pass on the first try; others need two or three attempts. The test is designed to measure your knowledge, not to trick you, so if you study the material and understand it, you should pass.
If you fail multiple times, consider whether you need a different study approach. Some people benefit from reading the guide aloud, others from taking notes, and others from studying with a friend who can quiz them. The DOL office staff can also point you toward additional resources if you're struggling.
After You Pass the Knowledge Test
Passing the knowledge test is one step toward getting your driver's license. If you're a new driver, you'll next take a driving skills test with an examiner who watches you drive and evaluates your ability to control the vehicle, follow traffic laws, and respond to road conditions. If you're renewing or upgrading an existing license, you may not need a skills test.
Your passing score is valid for a set period — typically 12 months in Washington — so you have time to schedule and complete your skills test without rushing. If your score expires before you finish the licensing process, you'll need to retake the knowledge test.
Once you pass both the knowledge test and the skills test (if required), you'll receive your driver's license. Washington issues licenses that are valid for several years, depending on your age and the type of license you hold.
Frequently Asked Questions
Can I take the test in a language other than English?
Yes. Washington offers the knowledge test in Spanish, Vietnamese, Korean, Chinese, Russian, and several other languages. When you schedule your appointment online or by phone, you can select your preferred language. If you need an interpreter for a language not listed, contact your local DOL office to discuss options.
What if I fail the test three or four times?
There's no limit on how many times you can retake the test. Each time you fail, you get a score report showing which topics to study. If you're struggling after multiple attempts, ask the DOL staff whether they can refer you to a driving school or instructor who offers test preparation — some schools specialize in helping people who have failed before.
Do I need to pass the knowledge test before I can get a learner's permit?
No. In Washington, you can get a learner's permit without taking the knowledge test. The permit lets you practice driving with a licensed adult. You take the knowledge test later, when you're ready to move toward a full driver's license. Some people take both tests in the same visit; others space them out.
How long does the test take?
Most people finish the 35-question test in 20 to 30 minutes. You're not rushed — you can take as long as you need to read and answer each question. The computer won't move to the next question until you select an answer, so you control the pace.
What if I have test anxiety or a learning disability?
Contact your local DOL office at least a week before your scheduled test to request accommodations. Washington can provide extra time, a quiet testing room, a reader, or other supports depending on your documented needs. Bring medical records or a letter from a healthcare provider explaining your disability and recommended accommodations.
