According to Washington State Department of Licensing, “You must get 32 out of 40 correct answers to pass the test.”[1]
The Washington State Knowledge Test is part of the learner permit process described by the Washington State Department of Licensing. You take the test in person at an approved testing location. It has 40 questions, and you must answer 32 correctly to pass. That is a passing score of 80%.
Permit eligibility depends on age and driver training: the minimum age is 15 with a driver training course, or 15½ without one. Check the Department of Licensing page titled Get your learner permit for the official permit requirements. Your learner permit is valid for 1 year and can be renewed twice.
The test fee varies by testing location. Ask your chosen location what it charges before arranging your test. If you do not pass, you may retest, but there may be a waiting period. Check the applicable wait with the testing location before making another appointment.
A passing knowledge test score is valid for 2 years. That is separate from the learner permit's validity. The Department of Licensing page titled Do I need to take a test? is the official source for the test score requirement, variable fees, retesting information, and passing-score validity.
These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.
Question: You see a tow truck stopped on the shoulder with its warning lights flashing. If you cannot safely change lanes away from it, you should:
Answer: C. Slow down below the posted speed limit and pass with caution
Explanation:
Slow down below the posted speed limit and pass with caution. The question says you cannot safely change lanes away from the stopped tow truck. Slowing down is the required response in that situation under the rule described here. Keeping your speed ignores that requirement. Stopping completely behind the truck is not the required response to this scenario. Using your horn does not replace slowing down or moving away. Remember the decision in this order: move away from the vehicle with flashing warning lights when you can do so safely; when you cannot, reduce your speed and pass cautiously.
Question: What does a solid white line on the right edge of a Washington road indicate?
Answer: B. The edge of the travel lane or shoulder
Explanation:
The line marks the edge of the travel lane or shoulder. Its position matters: the question places a solid white line on the right edge of the road, where it separates the travel lane from the shoulder. The center of the road is wrong because this marking is at the outside edge. A bicycle lane boundary is wrong because the marking described does not, by itself, identify a bicycle lane. A pedestrian crossing is wrong because this line follows the road's edge rather than marking a crossing. Remember to read a marking's location along with its color and pattern.
Question: How far from a fire hydrant must you park in Washington State?
Answer: C. 15 feet
Explanation:
You must park at least 15 feet from a fire hydrant. The purpose of this clearance is to keep the hydrant accessible to firefighters. The 5 feet and 10 feet options are wrong because both leave less than the required clearance. The 20 feet option is not the correct answer to the minimum-distance question: parking that far away would exceed the hydrant clearance requirement, but it is not the minimum stated in the rule. Remember that a minimum tells you the closest permitted distance. It does not mean you must park at exactly that distance.
Start with the official Washington State Department of Licensing study material. Read a topic, then use the matching practice set to check whether you can apply the rule without looking it up. Treat the sets as study categories, not an official exam outline.
After an incorrect answer, write down the rule and explain why your choice did not fit. Return to that topic after reviewing the official material. Before test day, confirm that your testing location is approved and ask about its fee. If you are retesting, check whether a waiting period applies.
You must take the knowledge test in person at an approved testing location. The Washington State Department of Licensing states this requirement on its learner permit page. Online practice is separate from that in-person test requirement; arrange your test with an approved location.
You need 32 correct answers out of 40 questions to pass the Washington State Knowledge Test. That is 80%. The Washington State Department of Licensing gives this requirement on its testing information page. A passing knowledge test score is valid for 2 years.
The fee varies by testing location. The Washington State Department of Licensing does not give a single test fee in the verified information here. Ask the approved location where you intend to test what it charges so you have the applicable fee before arranging your visit.
You may retest, but there may be a waiting period before you can try again. The Washington State Department of Licensing does not specify a fixed waiting period in the verified information here. Check with your testing location before scheduling another attempt.
You can be eligible at age 15 with a driver training course, or at 15½ without one. These are learner permit age requirements. Consult the Washington State Department of Licensing page titled Get your learner permit for the official requirements that apply to your situation.
The validity periods differ: a passing knowledge test score is valid for 2 years, while a learner permit is valid for 1 year. The permit can be renewed twice. Keep the score validity and permit validity separate when checking the Washington State Department of Licensing requirements.
