What the Missouri driver license written test covers
Missouri's written test for a driver license has 25 questions drawn from the state's Driver Guide. You must answer at least 19 correctly to pass. The test covers road signs, right-of-way rules, speed limits, parking laws, and safe driving practices specific to Missouri roads.
The questions are multiple choice with four options each. You take the test at a Missouri Department of Revenue office on a computer terminal. The test is offered in English and Spanish. You have no time limit to complete it, though most people finish in 10 to 15 minutes.
Missouri does not publish the exact questions used on the test, but the Driver Guide contains all the material the test draws from. The guide is free and available online at the Missouri Department of Revenue website, or you can pick up a printed copy at any license office.

How to find and use Missouri's Driver Guide
The Missouri Driver Guide is the official source for all test content. You can read it as a PDF from the Missouri Department of Revenue website under the "Driver Guides" section. The guide is organized by topic: traffic signs, right-of-way rules, speed and stopping, parking, and safe driving habits.
Read through the entire guide at least once before your test. Many people find it helpful to read it twice — once straight through to get the overall picture, and a second time to focus on sections where they feel less confident. The guide is written in plain language and includes illustrations of road signs and road markings.
Print the guide or read it on a screen, whichever works for you. Some people highlight key points or take notes as they read. Others make flashcards of the road signs. The method matters less than spending time with the material before you sit for the test.
Road signs and markings you need to know
Road signs make up a significant portion of the test. Missouri uses standard signs adopted across the United States, but the test will show you the actual sign and ask what it means or what you should do when you see it. Common signs include stop signs, yield signs, speed limit signs, and warning signs for curves, pedestrians, or school zones.
Pay close attention to the difference between regulatory signs (which are usually rectangular and tell you what you must or must not do) and warning signs (which are usually diamond-shaped and alert you to hazards ahead). The Driver Guide shows each sign type with an explanation of what it means.
Road markings — the lines painted on the road itself — also appear on the test. Yellow lines separate traffic moving in opposite directions. White lines separate traffic moving in the same direction. Solid lines mean you cannot cross; dashed lines mean you may cross if it is safe. The test will ask you to interpret these markings in different scenarios.
Right-of-way and intersection rules
Right-of-way questions test whether you know who has the legal right to go first at intersections and in other situations. Missouri law gives the right-of-way to the driver who reaches an intersection first, or if you arrive at the same time, to the driver on your right. The test will present scenarios — two cars approaching an intersection, a car and a pedestrian, a car and a bicycle — and ask who has the right-of-way.
Pedestrians have the right-of-way in marked crosswalks and at intersections where a pedestrian signal is present. Drivers must yield to pedestrians even if the pedestrian is crossing against the signal, though the pedestrian may be cited for doing so. School buses have special right-of-way rules: you must stop and remain stopped until the bus's red lights stop flashing and the stop arm is raised.
The test also covers turning rules. When turning left, you must yield to oncoming traffic and to pedestrians in your path. When turning right, you must yield to pedestrians crossing in front of you. These rules explore whether you are at a traffic light, a stop sign, or an uncontrolled intersection.
Speed limits and safe driving practices
Missouri's speed limit on interstate highways is 70 miles per hour unless otherwise posted. On other highways, the limit is 60 miles per hour. In residential areas and school zones, the limit is typically 20 to 25 miles per hour. The test will ask you to identify the correct speed for different road types and to understand that you must slow down below the posted limit if weather or road conditions make it unsafe to drive at that speed.
Safe driving practices cover topics like following distance, use of headlights, and what to do in an emergency. Missouri requires you to keep at least one car length of distance for every 10 miles per hour of speed — so at 30 miles per hour, keep at least three car lengths behind the vehicle ahead. You must use headlights from 30 minutes after sunset to 30 minutes before sunrise, and at any other time when visibility is poor.
The test includes questions about distracted driving, impaired driving, and what to do if your brakes fail or your vehicle skids. These are practical safety questions, not trick questions. The answers reflect common sense and Missouri law.
Parking laws and special situations
Parking questions cover where you can and cannot park, and what the different parking signs mean. You cannot park in a no-parking zone, in a fire lane, in a handicapped space without a permit, or within 15 feet of a fire hydrant. You cannot park on the wrong side of the street at night in a residential area. The test will show you parking signs and ask what they mean.
Special situations include what to do at a railroad crossing (stop at least 15 feet away if lights are flashing or gates are down), how to handle a funeral procession, and rules for towing. These questions are less common but do appear on the test. The Driver Guide covers all of them.
How to study effectively before test day
Start studying at least one week before your test date. Read the Driver Guide in full, then focus on the areas where you feel least confident. If road signs are difficult for you, spend extra time on that section. If right-of-way rules confuse you, work through the scenarios in the guide multiple times.
After you have read the guide, use a practice test to see how you perform. Many online practice tests are available that mimic the format and content of Missouri's actual test. These are not official Missouri tests, but they are based on the Driver Guide and give you a sense of the question types and difficulty level. Take a practice test under conditions similar to the real test: sit at a computer, do not use the Driver Guide, and time yourself loosely to see how long it takes.
Review any questions you miss on the practice test. Look up the correct answer in the Driver Guide and understand why that answer is right. If you miss several questions on the same topic, spend more time on that section before your next practice test.
What to bring and expect on test day
Bring a valid form of identification to the Missouri Department of Revenue office where you will take the test. Acceptable forms include a passport, a birth certificate, a Social Security card, or a school or work ID. You will also need to bring proof of your Social Security number and proof of your Missouri residency (a utility bill, lease, or bank statement with your name and address).
Arrive at the office at least 15 minutes before your scheduled appointment. You will check in at the counter, and a staff member will verify your documents and take your photo for the license. You will then be directed to a computer terminal to take the written test. The test is administered on a computer; you will not write anything by hand.
If you fail the test, you can retake it the same day at most offices, though you may have to pay a fee for the second attempt. Check with your local office about their retake policy and any associated costs before you arrive.
Frequently Asked Questions
Can I use the Driver Guide during the test?
No. The test is closed-book. You must rely on what you have studied beforehand. However, you have no time limit, so you can take as long as you need to think through each question.
What happens if I fail the test?
You can retake it the same day at most Missouri Department of Revenue offices. Some offices charge a fee for each attempt. Contact your local office to confirm their retake policy and any costs before you arrive.
Are the practice tests online the same as the real Missouri test?
Online practice tests are based on the Driver Guide and mimic the format and content of the real test, but they are not the official Missouri test. They are useful for studying, but the actual test questions may differ. Use them to identify weak areas, then study those topics in the Driver Guide.
How long does the test take?
Most people finish in 10 to 15 minutes, but there is no time limit. You can take as long as you need to answer all 25 questions. The entire visit to the license office, including check-in and photo, usually takes 30 to 45 minutes.
Can I take the test in a language other than English?
Yes. Missouri offers the written test in Spanish. Tell the staff member at the license office which language you prefer when you check in.
