Missouri does not require a written test to renew your driver's license
When you renew your Missouri driver's license, you will not take a written knowledge test, a road test, or any skills assessment. The state treats license renewal as a document and vision check, not a re-examination of your driving knowledge. This applies whether you renew in person at a Missouri Department of Revenue office or by mail.
The only test-like requirement is a vision screening. You must read letters or numbers on a chart from a set distance, usually 20 feet. If you wear glasses or contacts to drive, you must wear them during the vision test. If you fail the vision screening, the examiner will refer you to an eye care professional before your license can be renewed.
Missouri does require a written test only when you first obtain a driver's license (for new drivers) or when you explore for a different license class, such as upgrading to a commercial driver's license (CDL). Renewal of a standard Class D license does not trigger a written exam.
Key Takeaways
- Missouri renewal requires a vision test only; there is no written knowledge test for standard license renewal.
- You must pass the vision screening to renew, and you should wear your glasses or contacts if you normally drive with them.
- If you fail the vision test, you cannot renew until an eye care professional clears you to drive.
- Written tests are required only for new driver's licenses and upgrades to commercial or other license classes, not for renewal.
What the vision screening involves
The vision test in Missouri checks your ability to see clearly at a distance. You will stand or sit about 20 feet from a chart and read letters or numbers aloud. The examiner records whether you can read the required line of text. The standard is 20/40 vision or better in at least one eye, though Missouri may allow corrective lenses to meet this standard.
If you wear glasses, bifocals, or contact lenses while driving, wear them to your renewal appointment. The vision test measures your corrected vision, not your uncorrected vision. If you have recently changed prescriptions, bring your current glasses or contacts with you. Some people discover during renewal that their prescription has changed and they need to visit an eye doctor before they can pass the vision test.
If you fail the vision screening, the examiner will not renew your license on that day. You will receive a notice explaining the vision requirement and instructions to see an optometrist or ophthalmologist. Once an eye care professional signs off on your vision, you can return to the Department of Revenue office to complete the renewal.
Documents you need to bring to renewal
Although there is no written test, you must bring specific documents to prove your identity and residency. Missouri requires your current driver's license, proof of Social Security number (such as a Social Security card or W-2 form), and proof of Missouri residency (such as a utility bill, lease, or bank statement dated within the last 60 days).
If your name has changed since your last license was issued, bring a document showing the legal name change, such as a marriage certificate, divorce decree, or court order. If you are renewing by mail, you will mail copies of these documents along with your renewal process and fee. If you renew in person, bring the originals or certified copies; the examiner will verify them and return them to you.
Check the Missouri Department of Revenue website for the current list of acceptable documents before your appointment, as the list can change. Bringing the wrong documents will delay your renewal and may require a second visit.
In-person renewal versus mail renewal
Missouri allows you to renew by mail if you meet certain conditions: your license must not be expired by more than five years, you must have no medical restrictions on your license, and you must not need to update your photograph. If you renew by mail, you will not take a vision test in person. Instead, you will complete a vision self-assessment form and mail it with your process and documents.
If you renew in person at a Department of Revenue office, you will take the vision screening on the spot. In-person renewal also includes a new photograph for your license. The vision test takes only a few minutes and is part of the standard renewal process.
If you do not meet the conditions for mail renewal—for example, if your license expired more than five years ago—you must renew in person. You can find the nearest Department of Revenue office and check hours on the state website. Some offices require appointments; others accept walk-ins. Call ahead to confirm the process at your location.
What happens if you fail the vision test
Failing the vision screening does not mean you cannot renew your license. It means you cannot renew it that day. You must see an eye care professional—an optometrist or ophthalmologist—who will perform a full eye exam and determine whether you can legally drive. If the eye doctor clears you, they will sign a form or provide documentation that you bring back to the Department of Revenue.
Once you have the eye care professional's clearance, you can return to the Department of Revenue office to complete your renewal. You will not retake the vision test; the examiner will accept the eye doctor's documentation. This process can add one to two weeks to your renewal timeline, depending on how quickly you can schedule an eye appointment.
If the eye care professional determines that you cannot safely drive, your license will not be renewed. You may have the option to request a hearing or appeal, depending on Missouri law. Contact the Department of Revenue directly if you believe the vision test result was incorrect.
Timeline and fees for Missouri renewal
A standard Missouri driver's license is valid for six years. You can renew it up to one year before it expires. The renewal fee varies depending on how many years you are renewing for; as of recent years, a six-year renewal costs around $25 to $30, but you should confirm the current fee on the Missouri Department of Revenue website.
If you renew in person, the process typically takes 15 to 30 minutes, including the vision test and photograph. If you renew by mail, allow two to four weeks for processing and delivery. Do not wait until your license expires to renew; expired licenses cannot be renewed by mail and may require additional steps to restore.
If your license is already expired, you must renew in person. Bring all required documents and be prepared for the vision test. Processing may take longer for expired licenses, and you may face additional requirements depending on how long the license has been expired.
Frequently Asked Questions
Do I have to take a written test when I renew my Missouri driver's license?
No. Missouri does not require a written knowledge test for license renewal. You only need to pass a vision screening if you renew in person. If you renew by mail, you complete a vision self-assessment form instead.
What if I wear glasses—do I have to take the vision test without them?
No. Wear your glasses or contacts to the vision test if you normally wear them while driving. The test measures your corrected vision. If your prescription has changed, you may fail the test and need to see an eye doctor before renewing.
Can I renew my license by mail if I failed the vision test in person?
No. If you failed an in-person vision test, you must see an eye care professional and bring their clearance back to the Department of Revenue office. You cannot complete the renewal by mail after a failed vision test.
How long does the vision test take?
The vision screening itself takes only a few minutes. The entire in-person renewal process, including the photograph and document verification, typically takes 15 to 30 minutes.
What if I move out of Missouri before my license expires?
You should obtain a driver's license from your new state. Missouri will not renew a license for someone who no longer resides in the state. Contact your new state's Department of Motor Vehicles for their renewal and licensing requirements.
