Missouri requires you to identify road signs correctly on a written test when you renew your driver's license
When you renew your Missouri driver's license, the Department of Revenue will test your knowledge of road signs as part of the written exam. You will see images of actual road signs and choose the correct meaning from multiple-choice answers. The test covers signs you encounter on Missouri roads — stop signs, yield signs, speed limit signs, warning signs, and informational signs. You must pass this portion along with the rules-of-the-road section to pass the overall written test.
The road sign test is not separate from your renewal exam; it is built into the same written test you take at your local Missouri license office. You cannot skip it or take it at a different time. If you fail the road sign portion, you fail the entire written test and must retake it, though you can schedule another appointment right away.
Key Takeaways

- The test is administered on a computer at your local Missouri license office during your renewal appointment.
- Failing the road sign portion means failing your entire written test, but you can schedule a new appointment to retake it.
- Missouri provides a free study guide on its website that shows the actual signs and their meanings before you test.
What signs appear on Missouri's road sign test
Missouri's test focuses on signs you will actually encounter while driving. These include regulatory signs (stop, yield, speed limit, do not enter), warning signs (curve ahead, pedestrian crossing, slippery when wet), and informational signs (rest area, hospital, route markers). The test also covers signs related to parking, lane control, and temporary construction zones.
You will not see obscure signs or signs from other states. The test sticks to common road signs that every driver needs to recognize. Each question shows you a sign image and asks what it means or what action you should take when you see it. Some questions ask about the color and shape of a sign — for example, a yellow diamond means warning, and a red octagon means stop — because shape and color help drivers recognize signs quickly even from a distance.
How to study for the road sign portion
Missouri's Department of Revenue publishes a free study guide called the Missouri Driver Guide, available on the official Missouri Secretary of State website. The guide includes images of road signs and their meanings, organized by category. You can read it as a PDF or read it online before your renewal appointment.
The study guide is the same material the test draws from, so studying it directly prepares you for the questions you will see. Spend time on signs you do not encounter often — many drivers know a stop sign but may be less familiar with signs for divided highway ends or no-passing zones. Pay attention to the difference between similar signs: a yield sign is red and white, while a stop sign is red and octagonal.
You can also visit the Missouri Secretary of State website to take a practice written test online. This practice test includes road sign questions in the same format as the real exam, so you can see exactly how the questions are worded and timed.
What happens if you fail the road sign test
If you fail the road sign portion of your written test, you will be told when ready at the license office. You do not pass the overall written exam, and you cannot complete your license renewal that day. You will need to schedule another appointment to retake the written test.
There is no waiting period between attempts in Missouri — you can schedule your next test appointment as soon as you leave the office, though availability depends on your local office's schedule. You will pay the renewal fee again when you retake the test. Some offices allow you to retake the test the same day if space is available, but this varies by location, so ask the staff before you leave.
When you must take the road sign test during renewal
You take the road sign test every time you renew your driver's license in Missouri, regardless of how many times you have renewed before. The test is required for all renewal types: standard renewal, renewal by mail (if your state allows it), and online renewal (if you are renewing without a vision test).
If you renew online or by mail, you will still need to pass a written test. Missouri's online renewal option is available only if you meet certain conditions — your license is not suspended, you have no medical restrictions, and you are not changing your address. Even with online renewal, you must complete the written test, which includes road signs. The state will mail you instructions on how to take the test or direct you to a testing location.
Road sign test rules and what to bring
When you arrive for your renewal appointment, bring your current driver's license, proof of residency (a utility bill or lease), and proof of Social Security number (your Social Security card or a tax return). You will also need to pass a vision test before you take the written test. If you wear glasses or contacts while driving, wear them during the vision test.
The written test, including the road sign portion, is taken on a computer at the license office. You will have a set amount of time to complete the test — typically 30 minutes for the entire written exam. You cannot use notes, phones, or study materials during the test. The test is proctored, meaning a staff member watches to may support you are following the rules.
Frequently Asked Questions
Can I study road signs the night before my renewal appointment?
Yes. read the Missouri Driver Guide from the Secretary of State website and review it the evening before. Focus on signs you see less often — warning signs and informational signs trip up more drivers than stop and yield signs. Even an hour of study helps, since the test draws directly from the guide's content.
What if I fail the road sign test but pass the rules-of-the-road questions?
You fail the entire written test. Missouri does not separate the scores — you must pass both the road sign portion and the rules section to pass overall. You will retake the full written test at your next appointment, which means answering questions on both road signs and driving rules again.
Do I have to take the road sign test if I renew online?
Yes. Even if you renew online or by mail, you must still pass the written test, which includes road signs. Missouri will provide instructions on where and how to take the test as part of your renewal process. You cannot skip the written test for any renewal type.
How many road sign questions are on the test?
Missouri does not publish the exact number of road sign questions on its written test. The test is designed to cover the main categories of signs — regulatory, warning, and informational — but the exact breakdown varies. Study all sign types in the Missouri Driver Guide to be prepared.
What if I cannot see the sign images clearly on the computer screen?
Tell the staff member administering the test when ready. They can adjust the screen brightness or font size, or in some cases provide printed materials. Missouri's license offices are required to accommodate vision needs during testing, so speak up if you are having trouble seeing the images.
