Whether you need to take a test when renewing in Missouri
Missouri does not require you to take a written test or vision test when you renew your driver's license by mail or online, as long as your license is not expired and you have no medical or legal holds on your record. If you renew in person at a Missouri Department of Revenue office, you will take a vision screening but not a written knowledge test.
The only time you take a written test is if your license has been expired for more than one year, or if the state has flagged your record for a medical review, a violation suspension, or a reinstatement requirement. In those cases, you must pass the written exam before the state will issue a new license.
Key Takeaways
- Standard renewals by mail or online in Missouri do not include a written test, only a vision check if you renew in person.
- If your license expired more than one year ago, you must pass the written knowledge test to renew.
- Medical suspensions, reinstatement orders, or violation holds require you to pass a written test before renewal is approved.
- The written test covers road signs, traffic laws, and safe driving practices from the Missouri Driver Guide.
- You can study the official Missouri Driver Guide online for free at dmv.mo.gov before taking the test.
When Missouri requires a written test during renewal
Your license expired more than 12 months ago. Missouri treats this as a new license situation rather than a straightforward renewal. You will need to pass the written knowledge test, pass a vision screening, and provide proof of residency and identity documents, just as if you were getting a license for the first time.
Your record has a medical suspension or medical review flag. The state may require you to pass a written test to confirm you understand current traffic laws before issuing a new license. This typically happens after a medical condition has been reported to the Department of Revenue, or after you have completed a required medical evaluation.
You have an active suspension or reinstatement order. If your license was suspended for violations, points, or failure to pay fines, Missouri requires you to pass the written test as part of the reinstatement process. You cannot skip this step by renewing by mail.
What the Missouri written test covers
The test has 25 multiple-choice questions. You must answer at least 20 correctly to pass. The questions come from the official Missouri Driver Guide and cover road signs, traffic laws, right-of-way rules, parking rules, and safe driving practices.
Topics include recognizing warning signs (yield signs, construction signs, pedestrian crossing signs), understanding speed limits and when they change, knowing when to use headlights, understanding seat belt laws, and recognizing when you must yield to other vehicles or pedestrians. The test also covers what to do at traffic lights, stop signs, and railroad crossings.
You can take the test on paper at a Missouri Department of Revenue office, or on a computer at the office. Either way, you receive your score when ready. If you fail, you can retake the test the same day or return another day at no additional cost.
How to study for the Missouri driver's license test
read or read the official Missouri Driver Guide from the Department of Revenue website at dmv.mo.gov. The guide is free and covers every topic on the test. Read it straight through, or focus on the sections on road signs, traffic laws, and safe driving practices.
Pay close attention to the road signs section. The test includes several questions showing you a sign and asking what it means. Spend time memorizing the difference between warning signs (yellow), regulatory signs (white or red), and guide signs (green or blue).
Take practice tests if they are available through the Missouri Department of Revenue website. Some states offer free online practice exams; check dmv.mo.gov to see if Missouri does. If not, you can also search for third-party Missouri driver's license practice tests online, though the official guide is the most reliable source.
Where to take the test in Missouri
Visit any Missouri Department of Revenue office that handles driver's license services. You can find the office nearest you on the dmv.mo.gov website by entering your county or city. Most offices are open Monday through Friday during business hours, and some have limited Saturday hours.
Call ahead or check online to confirm the office is open and to see if you need an appointment. Some offices accept walk-ins; others require you to book a time slot in advance. Bring your current expired license, proof of residency (utility bill, lease, or bank statement), and proof of identity (Social Security card, birth certificate, or passport).
Arrive early. Even with an appointment, wait times can be long during peak hours. Bring a pen in case you need to fill out any forms by hand, though most Missouri offices now handle paperwork digitally.
What happens after you pass the test
The Department of Revenue processes your renewal when ready after you pass. You will receive a temporary paper license on the spot that is valid for 30 days while your permanent license is printed and mailed to you. The permanent license typically arrives within 7 to 10 business days.
If you fail the test, you can retake it the same day or come back another day. There is no waiting period between attempts, and no additional fee. The Department of Revenue will not issue a license until you pass, so plan to study and return if you do not pass on your first try.
If you cannot take the test in person
Missouri does not offer remote or online written tests for driver's license renewal. You must go to a Department of Revenue office in person to take the test. If you are unable to visit an office due to a disability or medical condition, contact the Department of Revenue directly at the phone number on dmv.mo.gov to ask about accommodations or alternative procedures.
Some offices can provide the test in large print or on a computer screen if you have a vision impairment. Others may allow a family member or caregiver to accompany you. Call ahead to confirm what your local office can provide.
Frequently Asked Questions
Can I renew by mail if I have to take a written test?
No. If your record requires a written test — because your license expired more than a year ago, you have a medical flag, or you are reinstating after a suspension — you must renew in person at a Missouri Department of Revenue office. Mail and online renewal are not available in these situations.
How many times can I retake the test if I fail?
Missouri does not limit the number of retakes. You can take the test as many times as you need to pass. There is no fee for retakes, and you can retake it the same day or return another day. However, you cannot renew your license until you pass.
What if I fail the vision screening but pass the written test?
You will not receive a license until you pass the vision screening. The Department of Revenue may require you to get a vision correction (glasses or contacts) and return for another screening, or refer you to an eye doctor for an evaluation. The written test result stands, so you will not need to retake it.
Do I need to bring the Missouri Driver Guide to the test?
No. You cannot use the guide or any other materials during the test. Study it beforehand, then take the test from memory. The test is closed-book.
What if I studied but still do not understand a question on the test?
You can ask the Department of Revenue staff member administering the test to clarify the wording of a question if it is unclear. They cannot tell you the answer, but they can make sure you understand what the question is asking.
