Missouri uses road signs to test your knowledge before renewal
Missouri's Department of Revenue includes road sign recognition on the written test you take during license renewal. You will see images of actual road signs and choose what each one means from multiple-choice answers. This is not a separate test — it is part of the standard knowledge exam that renewing drivers take at the license office.
The signs tested are the ones you encounter on Missouri roads: stop signs, yield signs, warning signs (like curves ahead or school zones), regulatory signs (like speed limits and no parking), and informational signs (like route markers and rest area directions). You need to know what each sign tells you to do, not just recognize its shape or color.
Most people pass this portion without studying because they drive past these signs regularly. But if you have not driven in several years, or if English is not your first language, reviewing the signs beforehand takes the guesswork out of test day.

Where to find Missouri road sign information
The Missouri Driver Guide is the official source for road sign meanings. You can read it free from the Missouri Department of Revenue website (dmv.mo.gov) or pick up a printed copy at any license office. The guide has a dedicated section with photographs of each sign, its name, and what it means.
The signs are organized by type: regulatory signs (red, white, and black) tell you what you must or must not do; warning signs (yellow and black) alert you to hazards ahead; and informational signs (green, blue, or brown) tell you where services or destinations are. Learning this organization helps you remember what each sign does.
You can also review signs online through the Missouri Department of Revenue website. Some people find it helpful to print the sign pages and study them for a few days before their renewal appointment, especially if they have not driven much recently.
What happens if you miss road sign questions on the test
If you answer road sign questions incorrectly during your written test, those wrong answers count toward your overall test score. Missouri requires you to pass the written test to renew your license. The passing score is typically 80 percent, though this can vary depending on the specific test version.
If you do not pass the written test on your first attempt, you can retake it the same day or schedule another appointment. There is usually a fee to retake the test (typically $5 to $10, though amounts vary). You will have a chance to study the Missouri Driver Guide between attempts.
Road sign questions usually make up a small portion of the overall test, so missing one or two does not automatically mean you fail. The test also covers right-of-way rules, speed limits, parking laws, and safe driving practices.
How road signs are tested during renewal
The written test is administered on a computer at the license office. You will see a photograph of a road sign on the screen and read four possible meanings. You select the answer you believe is correct and move to the next question. The test is timed, though most people finish with time to spare.
The signs shown are actual photographs, not drawings, so they look like the signs you see while driving. This makes the test practical — you are learning to recognize the real thing, not a stylized version. The multiple-choice format means you do not have to spell or write anything; you just select the right answer.
You cannot bring notes, phones, or study materials into the testing area. The test is proctored to may support fairness. If you need accommodations due to a disability or language barrier, contact your local license office before your renewal appointment to arrange them.
Common road signs tested in Missouri
Stop signs (octagonal, red and white) mean you must come to a complete stop and check for traffic before proceeding. Yield signs (triangular, red and white) mean you must slow down and let other traffic pass if necessary. Speed limit signs (rectangular, white and black) tell you the maximum speed allowed on that road.
Warning signs (diamond-shaped, yellow and black) alert you to upcoming hazards like curves, school zones, pedestrian crossings, or slippery roads. Do Not Enter signs (rectangular, red and white) mean the road is one-way in the opposite direction. No Parking signs (rectangular, red and white) mean you cannot leave your vehicle there.
Route markers (shields in various shapes) tell you which highway or road you are on. Informational signs (rectangular, green and white or blue and white) point to rest areas, hospitals, gas stations, and other services. Pedestrian crossing signs (usually diamond-shaped, yellow and black) warn drivers that pedestrians may cross at that location.
Preparing for the road sign portion of your test
Start by downloading or picking up the Missouri Driver Guide at least a week before your renewal appointment. Spend 10 to 15 minutes a day reviewing the road sign section. Focus on the signs you see least often while driving — most people know stop and yield signs already.
If you have a smartphone, take photos of the sign pages or use the online version to quiz yourself. Some people find it helpful to draw the signs or write their meanings by hand, which reinforces memory. Others prefer to read through the guide once and trust their existing knowledge.
On the day of your test, arrive early so you are not rushed. Read each question carefully and look at the sign photograph closely before selecting your answer. If you are unsure, take your best guess — there is no penalty for guessing, and you move forward either way.
What to bring to your renewal appointment
Bring your current Missouri driver's license or state ID, proof of residency (like a utility bill or lease), and proof of Social Security number (like a Social Security card or tax return). You will also need to pass a vision test and the written knowledge test, which includes the road sign questions.
If you are renewing by mail or online, you will not take a written test at all. Road sign questions only appear if you renew in person at a license office. Check the Missouri Department of Revenue website to see whether you are may be able to access to renew by mail or online based on your age and license status.
Frequently Asked Questions
Can I study road signs the night before my renewal appointment?
Yes. Reviewing the Missouri Driver Guide the night before is better than not reviewing at all. Most people find that even a quick read-through helps them feel more confident during the test. If you have more time, spreading your study over several days helps the information stick better.
Are the road signs on the Missouri test the same as in other states?
Most road signs are standardized across the United States, so a stop sign in Missouri looks the same as a stop sign in California. However, some warning signs and informational signs vary by region. The Missouri test covers only signs you will see in Missouri, so study the Missouri Driver Guide rather than a generic guide.
What if I fail the written test because of road sign questions?
You can retake the test the same day or schedule another appointment. There is usually a small fee to retake it. Between attempts, review the Missouri Driver Guide again, focusing on the signs you missed. Most people pass on their second attempt.
Do I have to take the written test if I renew online or by mail?
No. If you renew online or by mail, there is no written test and no road sign questions. You only take the written test if you renew in person at a license office. Check whether you are may be able to access for mail or online renewal based on your age and how long it has been since your last renewal.
Are there any road signs I should focus on more than others?
Focus on signs you encounter less often while driving. Most people know stop, yield, and speed limit signs already. Spend more time on warning signs (like curves ahead or slippery road), regulatory signs you might not see daily (like no left turn), and informational signs. The Missouri Driver Guide highlights the most commonly tested signs.
