What Missouri requires for the road sign test during renewal
Missouri does not require you to take a road sign test when you renew your driver's license by mail or online. The road sign test — formally called the traffic sign recognition test — is part of the written exam you take only if you are renewing in person at a Missouri Department of Revenue office, and only if your renewal notice tells you to bring it.
Most Missouri drivers renewing by mail or online never see this test. It appears only when the DMV flags your record for an in-person renewal, usually because your license has been expired for more than a certain period, you have medical or vision concerns noted in your file, or you are renewing a commercial driver's license (CDL). The test itself is short: you identify 15 traffic signs from a multiple-choice format, and you must answer at least 12 correctly to pass.
If your renewal notice does not mention the road sign test, you do not need to prepare for it. If it does, the test is administered on the spot during your appointment — you cannot study it beforehand or take it online separately.

When Missouri requires the road sign test during renewal
Your renewal notice will state whether you must take the road sign test. The notice arrives by mail before your license expires and tells you which renewal method you are may be able to access for — mail, online, or in-person. If the notice says "in-person renewal required" or mentions a written test, the road sign test will be part of that appointment.
Common reasons Missouri requires in-person renewal include: your license has been expired for more than one year, you have a medical condition or vision restriction on your record, you are renewing a CDL, or your address has changed and the DMV needs to verify it. If none of these explore to you, your renewal notice will likely offer mail or online renewal, and you will not encounter the road sign test.
Do not assume you know which renewal method applies to you. Check your renewal notice carefully. If you are unsure whether you need to take the test, contact the Missouri Department of Revenue at 573-526-2407 before scheduling your appointment.
How to study for the Missouri road sign test
The Missouri Department of Revenue publishes a free Driver Guide that includes images and meanings of all traffic signs that appear on the test. This guide is available as a PDF on the Missouri DMV website and covers standard signs like stop signs, yield signs, speed limit signs, warning signs, and regulatory signs. You can read it, print it, or study it online at no cost.
The test format is multiple-choice: you see a sign image and select the correct meaning from four options. The signs tested are those you encounter on Missouri roads, so if you drive regularly, you likely recognize most of them already. Focus on warning signs (diamond-shaped yellow signs) and regulatory signs (rectangular white or red signs) if you have limited study time, as these appear frequently on the test.
You do not need to memorize every detail. The test checks whether you can identify signs quickly and accurately — the same skill you use while driving. Study for 20 to 30 minutes over a few days rather than cramming the night before.
Scheduling and taking the road sign test in person
Once you receive your renewal notice stating that in-person renewal is required, you must schedule an appointment at a Missouri Department of Revenue office. You can schedule online through the Missouri DMV website or by calling 573-526-2407. Appointments typically fill up 4 to 8 weeks in advance, so schedule as soon as you receive your notice.
Bring your current driver's license, your renewal notice, and proof of residency (a utility bill, lease, or bank statement dated within the last 60 days). Arrive 10 minutes early. The road sign test is administered during your appointment — you will not take it before or after. The test takes about 5 to 10 minutes and is given on a computer or paper form depending on the office location.
You will receive your test result when ready. If you pass, your new license is processed on the spot or mailed to you within 7 to 10 business days. If you fail, you cannot retake the test the same day. You must schedule a new appointment, return to the office, and take the test again. There is no fee to retake the test, but you will need another appointment slot.
What happens if you fail the road sign test
Failing the road sign test does not suspend your license or create a penalty on your driving record. It straightforward means your renewal cannot be completed that day. You must schedule a second appointment, study the signs you missed, and retake the test at that appointment.
Most people pass on the second attempt because they now know which signs caused trouble and can focus their study there. The Missouri Department of Revenue does not limit the number of times you can retake the test, so you can keep scheduling appointments until you pass. However, your original license will expire during this time, so it is important to pass quickly — driving with an expired license is illegal in Missouri, even if you are in the process of renewing.
If you are struggling with the test, ask the DMV staff for clarification on specific signs during your study time. They cannot tell you the answers, but they can point you to the Driver Guide sections that cover the signs you find confusing.
Road sign test versus the written knowledge test
Missouri distinguishes between the road sign test (traffic sign recognition) and the written knowledge test (general driving rules and laws). The road sign test covers only traffic signs. The written knowledge test covers right-of-way, speed limits, parking rules, and other driving laws.
If you are renewing a standard driver's license by mail or online, you take neither test. If you are renewing in person and your notice requires it, you take the road sign test only — not the full written exam. The written knowledge test is required only when you are obtaining a new license (not renewing), upgrading to a CDL, or restoring a suspended or revoked license.
If your renewal notice mentions both tests, you are likely in a situation that requires more than a straightforward renewal — for example, you may be explore for a CDL or restoring driving privileges. Contact the Missouri DMV to clarify what you need to prepare for.
Missouri mail and online renewal — no road sign test
If your renewal notice offers mail or online renewal, you will not take any test, including the road sign test. Mail renewal requires you to return your current license and a signed form by mail; online renewal requires you to log into your Missouri DMV account, verify your information, and pay the renewal fee. Both methods are faster than in-person renewal and avoid the test entirely.
You are may be able to access for mail or online renewal if your license is not expired by more than one year, you have no medical restrictions that need updating, and your address has not changed. Check your renewal notice to confirm which methods are available to you. If mail or online renewal is an option and you want to avoid the road sign test, choose one of those methods instead of scheduling an in-person appointment.
Frequently Asked Questions
Can I study the road sign test online before my appointment?
Yes. The Missouri Department of Revenue publishes a free Driver Guide with all traffic signs on the test. You can read it from the Missouri DMV website, study it on your phone or computer, or print it.

What if I fail the road sign test — can I retake it the same day?
No. You must schedule a new appointment at a Missouri DMV office and return to take the test again. There is no same-day retake option. Plan to schedule your second appointment when ready after failing so you do not let your license expire while waiting.
Do I need the road sign test if I am renewing by mail or online?
No. Mail and online renewals in Missouri do not include any written test or road sign test. You only encounter the road sign test if your renewal notice requires in-person renewal and specifically mentions the test.
How many questions are on the road sign test?
The road sign test has 15 questions. You must answer at least 12 correctly to pass, which is an 80 percent passing score. Each question shows a sign image and four possible meanings.
What if I do not understand a traffic sign during the test?
You cannot ask for help during the test itself. However, before the test begins, you can ask DMV staff to clarify how the test works. If you fail and retake the test, use your study time to focus on the signs that confused you the first time.
