How Washington's written test works

Washington's written knowledge test is a computer-based exam you take at a Department of Licensing (DOL) office. You answer 35 multiple-choice questions about traffic laws, road signs, and safe driving practices. You need to score at least 80 percent — that means 28 correct answers out of 35 — to pass.

The test covers Washington's traffic laws specifically, not general driving rules. The questions come from the Washington Driver Guide, which you can read online or pick up at any DOL office. 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 entire process — check-in, test, and results — usually takes 30 to 45 minutes. You'll sit at a computer terminal in a testing booth, and the system shows you your score when ready after you finish.

Key Takeaways

  • Washington's written test has 35 multiple-choice questions, and you must answer at least 28 correctly to pass.
  • All test questions come from the Washington Driver Guide, which is free and available online or at DOL offices.
  • You take the test on a computer at a Department of Licensing office, and you get your score right away.
  • You can retake the test the same day if you fail, or schedule another appointment at a different time.

What the test covers

The 35 questions are divided among several topics: traffic signs and their meanings, right-of-way rules, speed limits and safe speeds, parking laws, vehicle equipment requirements, and impaired driving laws. Washington also tests heavily on rules specific to the state — for example, how to handle a flashing red light versus a solid red light, or when you can legally use the carpool lane.

About one-third of the questions focus on signs and what they mean. Another third covers right-of-way situations: who goes first at a four-way stop, what to do when a school bus is loading, how to yield to pedestrians and cyclists. The remaining questions test your knowledge of Washington laws on speeding, following distance, seat belts, child safety seats, and driving under the influence.

Every question on the test appears in the Washington Driver Guide. The guide is organized by topic, so you can study the sections that matter most to you. Many people find it helpful to read through the entire guide once, then focus on the areas where they feel less confident.

How to study for the Washington test

Start by reading the Washington Driver Guide from beginning to end. You can read it as a PDF from the Washington DOL website, or request a printed copy at any DOL office. The guide is written in plain language and includes photos of actual road signs and traffic situations you'll see in Washington.

After you've read through the guide once, use practice tests to find the topics where you need more work. Washington DOL offers a free practice test on its website that mimics the real exam — same number of questions, same format, same time limit. Take the practice test under real conditions: sit at a computer, don't use notes or the guide, and give yourself the same amount of time you'll have on test day.

If you score below 80 percent on the practice test, go back to the guide and reread the sections where you missed questions. Then take the practice test again. Most people who study the guide and pass the practice test pass the real exam on their first try.

When and where to take the test in Washington

You take the written test at a Department of Licensing office. Washington has DOL offices in most cities and towns, and you can find the one nearest you on the DOL website. Each office has its own hours and may have different wait times depending on the day and time you visit.

You do not need an appointment for the written test — you can walk in during office hours. However, some offices get busy in the late afternoon or on Saturdays, so arriving early in the day or on a weekday usually means a shorter wait. Check the DOL website for your local office's hours before you go.

You must bring a valid form of identification — a passport, birth certificate, or state ID card. You also need to bring proof of your Social Security number, such as a Social Security card or a tax return. If you don't have these documents, the DOL office can tell you what alternatives they accept.

What happens if you fail the test

If you score below 80 percent, you do not pass. You can retake the test when ready — most DOL offices will let you take it again the same day if you want to. There is no waiting period between attempts, though you do have to pay the test fee again.

Many people find it helpful to fail once and then study harder before the second attempt. Knowing which topics tripped you up the first time helps you focus your studying. If you fail a second time, take a longer break, go back to the guide, and consider studying with a friend or family member who can quiz you on the material.

There is no limit to how many times you can retake the written test. You can come back as many times as you need to until you pass.

After you pass the written test

Once you pass, you'll receive a receipt showing your passing score. This receipt is your proof that you passed the knowledge test. You'll need it when you schedule your road test at a DOL office.

Your passing score is valid for one year. That means you have 12 months from the date you pass the written test to take and pass your road test. If you don't take the road test within that year, you'll have to retake the written test before you can schedule a road test appointment.

The next step is the road test, where a DOL examiner watches you drive and scores your ability to handle a vehicle safely on real roads. You'll need to bring your own vehicle, proof of insurance, and your passing knowledge test receipt to the road test appointment.

Frequently Asked Questions

Can I use the Washington Driver Guide during the test?

No. The test is closed-book — you cannot use the guide, notes, or any other materials while you're taking the exam. You study the guide beforehand, then take the test from memory. You can bring the guide with you to the DOL office, but you have to put it away before the test starts.

How long do I have to answer all 35 questions?

Washington does not set a strict time limit for the written test. You have as much time as you need to read each question and choose your answer. Most people finish in 20 to 30 minutes, but you can take longer if you need to.

What if I fail the written test three times?

You can retake it as many times as you need. There is no limit on the number of attempts. If you keep failing, consider studying with someone else, asking a DOL staff member which topics are giving you trouble, or taking a longer break before your next attempt.

Do I have to pass the written test before I can take the road test?

Yes. You must pass the knowledge test first and bring your passing score receipt to your road test appointment. You cannot schedule a road test without proof that you passed the written test.

Is the practice test on the Washington DOL website the same as the real test?

The practice test has the same format, number of questions, and passing score as the real test, but the actual questions are different. Using the practice test helps you get used to the computer format and find weak areas, but you still need to study the driver guide to learn the material.
