What road signs Missouri tests on your renewal exam
Missouri's renewal written test includes questions about road signs you'll encounter while driving. The test focuses on signs that affect how you navigate traffic, respond to hazards, and follow the law. You don't need to memorize every sign in existence — the Department of Revenue tests on the ones that matter most for safe driving.
The signs fall into a few categories: warning signs (usually yellow with black symbols), regulatory signs (white with black or red text), and informational signs (green, blue, or brown). The test draws from the Missouri Driver Guide, which is free and available on the Department of Revenue website. Most people who study the guide before taking the test pass the sign questions without trouble.

Warning signs: yellow signs that alert you to hazards
Warning signs are diamond-shaped and yellow with black symbols or text. They tell you what hazard is coming up so you can slow down or change your driving. Common warning signs on the renewal test include curves ahead, pedestrian crossing, slippery road, hill or steep grade, and divided highway ending.
Other warning signs you may see tested are railroad crossing, school zone, construction zone, and animal crossing. These signs don't order you to do anything — they're telling you to be ready. The test usually asks you to identify what the sign means or what action you should take when you see it, such as "reduce speed" or "be prepared to stop."
Regulatory signs: white signs that tell you what you must do
Regulatory signs are rectangular, usually white with black text or symbols, and they enforce traffic laws. Stop signs are octagonal and red with white text — you must come to a complete stop. Speed limit signs are rectangular and white; the number tells you the maximum speed allowed on that road.
Other regulatory signs include yield (triangular, red and white), do not enter (rectangular, red and white), one-way (rectangular, white with black arrow), and no parking (white with red circle and slash). The renewal test asks you to recognize these signs and understand what they require you to do. Ignoring a regulatory sign can result in a traffic ticket, so knowing them matters both for the test and for staying legal on the road.
Informational signs: green, blue, and brown signs that guide you
Informational signs help you navigate and find services. Green signs show directions to highways or cities. Blue signs point to rest areas, hospitals, gas stations, and other services. Brown signs mark scenic areas, historical sites, and recreational facilities.
The renewal test usually includes a few questions about what these signs mean and where they direct you. You won't be asked to memorize every exit number or distance, but you should know that a green sign with white text gives directional information and a blue sign offers services or facilities nearby.
How to study road signs for your Missouri renewal test
Start with the Missouri Driver Guide, which you can read as a PDF from the Department of Revenue website or request in print by mail. The guide has a section dedicated to road signs with images and explanations. Read through it once to get familiar with the signs, then go back and focus on the ones you're less sure about.
The Department of Revenue also offers a free practice test on its website that includes sample questions about road signs. Taking the practice test shows you the format of the actual renewal exam and helps you identify which signs need more study. Many people find that spending 20 to 30 minutes with the guide and practice test is enough to feel confident on test day.
What happens if you miss road sign questions on the test
The Missouri renewal written test has a passing score of 80 percent. If you miss road sign questions and your overall score falls below 80, you'll be told which sections to review before retaking the test. You can retake the written portion the same day at most license offices, so you won't have to wait or come back another time.
If you fail the test, the examiner or staff member can point you toward the sections of the Driver Guide that cover what you missed. Most people pass on the second attempt after reviewing those specific areas. There's no penalty for retaking the test — you just pay the renewal fee once.
Road signs that change by location or season
Some signs are temporary or location-specific. Construction zone signs appear and disappear depending on road work. School zone signs are active during school hours and may have flashing lights. Winter weather warning signs appear in colder months. The renewal test focuses on permanent, standard signs you'll see year-round, but knowing that temporary signs exist and what they mean is part of safe driving.
The Driver Guide covers these variations so you understand the context. For example, you should know that a school zone sign means you must reduce speed during the posted hours, not all day. This kind of detail shows up on the test because it affects how you actually drive.
Frequently Asked Questions
Can I bring the Missouri Driver Guide with me to the renewal test?
No. The written test is closed-book. You must study the guide before you go to the license office. However, you can study it for as long as you need before your appointment — there's no time limit on how long you can prepare.
Are there road signs on the renewal test that aren't in the Driver Guide?
No. The Department of Revenue only tests on signs that appear in the current Missouri Driver Guide. If you study the guide thoroughly, you'll have seen every sign that could appear on your test.
How many questions about road signs are on the renewal test?
The exact number varies, but road signs typically make up a portion of the written test along with questions about traffic laws, right-of-way, and safe driving practices. The practice test on the Department of Revenue website shows you the mix and format you'll encounter.
What if I fail the road sign section but pass the rest of the test?
You don't pass or fail individual sections — the test is scored as a whole. If your overall score is below 80 percent, you retake the entire test. The examiner will tell you which topics to review, and you can focus on road signs if that's where you struggled.
Do I need to know international road signs for the Missouri renewal test?
No. The test covers only signs used in the United States and specifically in Missouri. The Driver Guide shows you the standard signs you'll encounter on Missouri roads.
