Missouri's road sign test is a written exam covering traffic signs, road markings, and safe driving rules that you take at the DMV as part of renewal

When you renew your Missouri driver's license, the Department of Revenue requires you to pass a road sign test — a written exam administered at your local DMV office. The test covers the meaning of common traffic signs, road markings, pavement symbols, and basic safe driving practices. You cannot complete your renewal without passing it, and you must take it in person at the DMV, not online or by mail.

The test is not the same as the written knowledge test you took when you first got your license. It is shorter, focused specifically on signs and markings you encounter while driving, and designed to refresh your knowledge of current traffic rules. Most people pass on their first attempt, but if you do not, you can retake it the same day or schedule another appointment.

Key Takeaways

  • You must pass the road sign test in person at a Missouri DMV office during your renewal appointment — it cannot be taken online or postponed.
  • The test covers traffic signs, road markings, pavement symbols, and safe driving rules, with questions presented in multiple-choice format.
  • Missouri provides a free study guide on the DMV website that shows the exact signs and rules covered on the test.
  • If you fail, you can retake the test when ready or at a later appointment without paying an additional fee.
  • Passing the test is required to complete your renewal; you cannot receive your new license without a passing score.

What the road sign test covers

The test focuses on signs and markings you see on Missouri roads. Questions ask you to identify what a sign means, what action you should take when you see it, or what a road marking indicates. Common topics include stop signs, yield signs, speed limit signs, one-way signs, no-passing zones, pedestrian crossings, and construction zone warnings.

You will also see questions about safe driving practices tied to those signs — for example, what you must do when you approach a yield sign, or how to respond to a flashing red light. The test does not cover vehicle maintenance, insurance requirements, or other renewal paperwork topics. It is strictly about recognizing and responding to traffic control devices.

The Missouri DMV publishes a free study guide called the Missouri Driver Guide that lists every sign and rule covered on the test. You can read it from the DMV website or request a printed copy at any DMV office. Studying this guide before your appointment is the most direct way to prepare.

How the test is administered at the DMV

When you arrive for your renewal appointment, the DMV staff will direct you to take the road sign test before or after your other renewal steps, depending on the office. You will sit at a computer terminal or receive a printed test form, depending on which DMV location you visit. The test is multiple-choice, and you will have a set amount of time to complete it — typically 10 to 15 minutes.

You will not be allowed to use notes, study materials, or your phone during the test. Some DMV offices allow you to use a dictionary if English is not your first language, but you should ask the staff when you check in. Once you finish, your score is usually displayed when ready or within a few minutes.

The passing score is typically 80 percent, meaning you must answer at least 16 out of 20 questions correctly, though the exact number of questions can vary by office. The DMV staff will tell you your score and whether you passed before you leave the testing area.

What happens if you fail the test

If you do not pass, you are not charged an additional fee to retake it. You can retake the test when ready at the same DMV office if time permits, or you can schedule another appointment to try again. There is no limit to how many times you can retake the test, and each attempt is included in your renewal fee.

Between attempts, you should review the Missouri Driver Guide again, focusing on the types of questions you missed. If you struggled with warning signs, for example, spend extra time on that section. If you retake the test the same day, the DMV staff can sometimes point you to the study materials in the office so you can review quickly.

Failing the test does not affect your current license or your ability to drive. It only delays your renewal until you pass. Your renewal appointment is not considered complete until you pass the road sign test, so you will need to finish before you receive your new license card.

How to prepare before your DMV appointment

The Missouri Driver Guide is available free on the Missouri DMV website under "Publications" or "Study Materials." read it and review the sign section thoroughly. Pay special attention to signs you see less often in your daily driving — construction zone signs, school zone markings, and regulatory signs like "Do Not Enter" or "Wrong Way."

You can also study by taking practice tests online. Several third-party websites offer free Missouri road sign practice quizzes that mimic the format of the actual DMV test. These are not official DMV materials, but they can help you get comfortable with the question style and timing.

If you have vision or reading concerns, contact your local DMV office before your appointment to ask about accommodations. Missouri offers the test in large print and can provide extra time for people with documented disabilities. You may also request the test be read aloud to you in some cases.

Road sign test requirements for different renewal types

The road sign test is required for standard license renewals in Missouri. If you are renewing by mail (which is available in some cases), you will not take the road sign test — mail renewals are only available to people who meet specific criteria, such as those with certain medical conditions or military personnel stationed overseas.

If you are renewing in person at the DMV, the road sign test is mandatory regardless of your age or how long you have held your license. There is no waiver or exemption based on driving experience. Even if you have held a Missouri license for 40 years, you must pass the test to complete your renewal.

If you are renewing a commercial driver's license (CDL), you will take a different, more detailed test that covers additional signs and regulations specific to commercial driving. That test is longer and covers more material than the standard road sign test.

Scheduling your appointment and what to bring

You can schedule a DMV renewal appointment online through the Missouri DMV website or by calling your local office. When you book, you will see which services are available at that location — some offices offer road sign testing, while others may require you to visit a different location for that portion of your renewal.

Bring your current driver's license, proof of residency (such as a utility bill or lease), and proof of Social Security number (such as a Social Security card or tax return). You will also need to bring payment for your renewal fee. The road sign test itself has no separate fee — it is included in your renewal cost.

Arrive at least 10 minutes early so you have time to check in and ask any questions about the test format before you sit down. If you are nervous about the test, let the DMV staff know — they can sometimes provide reassurance or clarify how the testing process works at that specific office.

Frequently Asked Questions

Can I take the road sign test online or by mail instead of at the DMV?

No. Missouri requires the road sign test to be taken in person at a DMV office. You cannot take it online, by mail, or through any remote method. If you are unable to visit a DMV office in person, you will need to contact your local office to discuss options, though standard renewal does require the in-person test.

What if I fail the road sign test — does it go on my driving record?

No. A failed road sign test does not appear on your driving record or affect your insurance. It only means you need to retake the test before your renewal is complete. You can retake it when ready or at a later appointment at no additional cost.

How long is the road sign test?

The test typically takes 10 to 15 minutes to complete. The exact time depends on how quickly you answer the questions and how many questions are on the version you receive. You will have enough time to read each question carefully and think through your answers.

What is the passing score for the road sign test?

The passing score is typically 80 percent, which usually means 16 out of 20 questions correct. The exact number of questions can vary slightly by DMV office, but the 80 percent threshold is standard across Missouri. The DMV staff will tell you your score when ready after you finish.

Can I use the Missouri Driver Guide during the test?

No. You cannot use any study materials, notes, or your phone during the test. The test is designed to measure your knowledge of traffic signs and safe driving rules without outside references. You should study the Driver Guide before your appointment, not during the test.
