What Road Signs You Need to Know for Missouri License Renewal
Missouri's license renewal test includes questions about road signs you may encounter while driving. The test focuses on signs that communicate warnings, instructions, and information — the ones that affect how you should drive or where you can go. You won't be tested on every sign in existence, but you will see questions about the most common ones: stop signs, yield signs, speed limit signs, and warning signs like curves ahead or pedestrian crossing.
The Missouri Department of Revenue publishes the official Missouri Driver Guide, which lists the signs you need to recognize. Most renewal tests include 2 to 4 questions about signs out of a total of 16 questions on the written exam. The signs appear as images, and you choose what the sign means or what action you should take when you see it.

- The Missouri Driver Guide, available free from the Department of Revenue, shows all signs you may encounter on the test.
- Warning signs are typically diamond-shaped and yellow; regulatory signs are rectangular and white, red, or green.

The Three Main Categories of Road Signs on the Missouri Test
Regulatory signs tell you what you must or must not do. These include stop signs (red octagon), yield signs (red and white triangle), speed limit signs (white rectangle), and do-not-enter signs (red rectangle with white horizontal bar). Failing to obey a regulatory sign can result in a traffic violation. On the renewal test, you will be asked to identify these signs and know what action they require.
Warning signs alert you to hazards or changes in road conditions ahead. These are typically diamond-shaped and yellow with black symbols or text. Common warning signs include curves ahead, pedestrian crossing, school zone, slippery when wet, and hill or steep grade. The test may show you a warning sign and ask what condition you should expect or how you should adjust your driving.
Informational signs provide directions or tell you about services and facilities. These are usually rectangular and green, blue, or brown. Examples include route markers, distance signs, and signs for rest areas or hospitals. Informational signs appear less frequently on renewal tests than regulatory or warning signs, but you should still be familiar with them.
How to Study Road Signs Before Your Missouri Renewal Test
The Missouri Department of Revenue provides the Missouri Driver Guide free of charge on its official website. The guide includes a full section on road signs with images and explanations. You can read it online or read it as a PDF to study at your own pace. This is the same material the test is based on, so studying the official guide is the most direct way to prepare.
Many people find it helpful to print out the sign section or use flashcards to memorize the shapes, colors, and meanings. Pay special attention to signs that look similar — for example, a yield sign (red and white triangle pointing down) and a stop sign (red octagon) are straightforward to confuse if you are not careful. Practice identifying signs by their shape and color first, then learn what they mean.
You can also take practice tests through the Department of Revenue website. These practice tests include road sign questions and show you the correct answer if you get one wrong. Taking a practice test a few days before your appointment helps you see which signs you need to review more carefully.
What Happens If You Miss Road Sign Questions on the Renewal Test
The Missouri renewal written test requires a score of at least 80 percent to pass. If you miss road sign questions, those points count toward your overall score just like any other question. Missing 2 or 3 sign questions out of 16 total questions may still allow you to pass, depending on how many other questions you answer correctly.
If you do not pass the written test on your first attempt, you can retake it the same day at most Missouri license offices. There is no waiting period between attempts. You will take a different version of the test with different questions, so you should spend time studying before your second attempt. Most people pass on the second try after reviewing the material more carefully.
Common Road Signs You Will Likely See on the Test
| Sign Type | Shape and Color | What It Means |
|---|---|---|
| Stop | Red octagon | Come to a complete stop and check for traffic before proceeding |
| Yield | Red and white triangle (pointing down) | Slow down and let other traffic pass; stop if necessary |
| Speed Limit | White rectangle | Maximum legal speed on that road |
| Do Not Enter | Red rectangle with white horizontal bar | Do not drive in this direction; you are going the wrong way |
| Pedestrian Crossing | Yellow diamond | Pedestrians may cross here; slow down and be ready to stop |
| Curve Ahead | Yellow diamond | Road curves; reduce speed and stay in your lane |
| School Zone | Yellow diamond or yellow rectangle | Reduced speed limit in effect during school hours |
| Slippery When Wet | Yellow diamond | Road surface may be slick; reduce speed and increase following distance |
Where to Find the Official Missouri Driver Guide
The Missouri Department of Revenue maintains the official Driver Guide on its website at dor.mo.gov. You can access the guide directly without creating an account or paying a fee. The guide is updated periodically to reflect changes in traffic laws or signs, so the version you study should match the version used for your test.
If you prefer a printed copy, you can request one at any Missouri license office when you arrive for your renewal appointment. Staff can also answer questions about specific signs if you are unsure about a sign's meaning. Some license offices have computers available for you to study before your test if you arrive early.
Frequently Asked Questions
Will the test show me pictures of signs or just ask me to name them?
The test shows you a picture of the sign and asks what it means or what you should do when you see it. You will not be asked to draw a sign or spell out its name. Seeing the actual image makes it easier to recognize the sign's shape and color, which are the key ways to identify it quickly.
Are there signs on the renewal test that were not in the Driver Guide?
No. The Missouri Department of Revenue bases the renewal test only on material in the official Driver Guide. If you study the guide thoroughly, you will have seen every sign that could appear on your test. The guide is designed to cover all signs you need to know.
Do I need to memorize every single sign in the Driver Guide?
You should focus on the most common signs first: stop, yield, speed limit, do-not-enter, and the most frequent warning signs like pedestrian crossing and curves ahead. These appear on nearly every test. Less common signs like specialized warning signs for specific hazards are less likely to appear, but reviewing the full guide takes only 20 to 30 minutes.
What if I fail the road sign questions but pass the rest of the test?
Road sign questions count the same as any other question toward your overall score. If you score 80 percent or higher overall, you pass the test regardless of which specific questions you answered correctly. However, if you miss enough questions to fall below 80 percent, you will need to retake the entire test.
Can I study road signs on my phone before my test appointment?
Yes. The Missouri Department of Revenue website is mobile-friendly, so you can view the Driver Guide and take practice tests on your phone. Many people study during their lunch break or while waiting for their appointment. Reviewing signs for 10 to 15 minutes right before your test can help refresh your memory.
