Missouri's permit test has 25 questions, and you need 20 correct to pass
The Missouri Department of Revenue administers a written test when you explore for your learner's permit or driver's license. The test contains exactly 25 questions drawn from the Missouri Driver Guide, and you must answer at least 20 of them correctly — that is an 80 percent passing score. The questions cover road signs, right-of-way rules, safe driving practices, and Missouri traffic laws.
You take the test at your local Missouri license office on a computer. The test is not timed, so you can take as long as you need to read each question and select your answer. You will see the results when ready after you finish, and the examiner will tell you whether you passed or failed.
If you do not pass, you can retake the test the same day or come back another day. There is no waiting period between attempts, though some offices may ask you to wait a few minutes before trying again.

What topics the 25 questions cover
The Missouri permit test draws all its questions from the Missouri Driver Guide, a free booklet you can read online or pick up at any license office. The questions test your knowledge of road signs and what they mean, right-of-way rules at intersections and four-way stops, speed limits and when they change, and safe driving practices like following distance and how to handle skids or hydroplaning.
You will also see questions about Missouri-specific laws: seat belt requirements, child safety seat rules, distracted driving rules, and what to do if you are pulled over by police. A few questions cover parking rules, turning rules, and how to share the road with pedestrians and bicycles.
The test does not ask you to do math or read complex scenarios. Each question is straightforward: you read a sign or a situation, and you pick the correct answer from four choices.
How the test is structured and scored
All 25 questions are multiple choice. You read the question and four possible answers on the computer screen, then click the answer you believe is correct. You cannot go back and change an answer once you move to the next question, so read carefully before you click.
The computer keeps track of how many you get right. When you finish all 25 questions, the system calculates your score and displays it on the screen. A passing score is 20 or higher. If you score 19 or lower, you have not passed and will need to retake the test.
The test does not show you which questions you missed, so if you fail, you will not know exactly which topics to study harder. The best approach is to review the entire Missouri Driver Guide again before your next attempt, paying extra attention to any sections you found confusing the first time.
How to prepare for the 25 questions
The Missouri Driver Guide is your main study resource. You can read it online at the Missouri Department of Revenue website or request a printed copy at any license office. The guide is organized by topic — signs, right-of-way, speed, safe driving, and Missouri laws — so you can study one section at a time.
Read through the guide once to get familiar with it, then go back and focus on the sections that seem hardest. Pay close attention to road signs, because the test always includes several sign-recognition questions. Right-of-way rules at intersections are another common topic, so make sure you understand who goes first at a four-way stop and how to handle a left turn across traffic.
Some people find it helpful to take notes while reading, writing down the main rule or the meaning of each sign in their own words. Others prefer to read the guide multiple times. Either way, the goal is to move from reading the guide to remembering the information without looking at it.
What happens if you fail the test
If you score below 20, you have not passed and cannot move forward with your license or permit that day. You will need to retake the test. Many license offices let you try again the same day — you can study for a few minutes and then take the test again. Other offices may ask you to come back another day.
There is no penalty for failing. You can retake the test as many times as you need. Each time you take it, you pay the test fee again, which varies by office but is usually between $5 and $10.
If you fail multiple times, take a step back and study the Missouri Driver Guide more thoroughly. Ask someone to quiz you on the material, or look for online practice tests that use questions similar to the real test. Sometimes a different study method clicks better than the first one you tried.
Bringing documents and what to expect on test day
Before you take the test, you will need to bring proof of identity and proof of residency to the license office. Acceptable documents include a birth certificate, passport, or state ID for identity, and a utility bill or lease for residency. The office staff will verify your documents before you sit down to take the test.
You will be seated at a computer in a quiet area of the office. The examiner will explain how to use the computer and answer any questions about how the test works. Then you will be left alone to take the test. You can raise your hand if you have a technical problem, but the examiner cannot help you with the content of the questions.
Bring a pen and paper if you want to take notes while reading questions, though some offices do not allow this. Ask the examiner before the test starts whether notes are permitted.
Online practice tests and study tools
Many websites offer free practice tests that mimic the Missouri permit test format. These are not official tests — they are created by third parties — but they use questions similar to the real test and help you get used to answering multiple-choice questions on a computer.
Practice tests are most useful after you have read the Missouri Driver Guide at least once. Use them to find weak spots in your knowledge, then go back to the guide and reread those sections. Taking a practice test a second time after studying will show you whether you have improved.
Keep in mind that practice tests are not identical to the real test. The real test pulls from the official Missouri Driver Guide, so studying the guide itself is always your best preparation. Use practice tests as a supplement, not a replacement.
Frequently Asked Questions
Can I use my phone or notes during the test?
No. The test is proctored, meaning an examiner watches to make sure you do not use outside materials. You cannot use your phone, notes, or the internet during the test. You must answer based on what you have studied.
How long does the 25-question test take?
There is no time limit, so it depends on how fast you read and decide. Most people finish in 10 to 20 minutes. You can take longer if you need to think through a question carefully.
What if I fail the test three times?
You can retake the test as many times as needed. There is no limit on the number of attempts. Each time you fail, study the Missouri Driver Guide more thoroughly before trying again, and consider asking someone to quiz you on the material.
Are the questions on the real test the same as practice test questions?
Not exactly. Practice tests use similar questions and topics, but the real test pulls from the official Missouri Driver Guide. Practice tests are useful for learning the format and testing your knowledge, but studying the actual guide is the most direct preparation.
Do I have to pass the written test to get a permit?
Yes. The written test is required to get a learner's permit or driver's license in Missouri. You must pass the test before you can move on to the driving test or receive your license.
