Missouri requires a vision test every time you renew your driver's license
When you renew your Missouri driver's license, the Department of Revenue will test your vision as part of the renewal process. This is not optional — you cannot complete a renewal without passing the vision screening. The test checks whether you can see well enough to drive safely, and the standards are set by Missouri law, not by individual examiners.
The vision test happens at the same location where you handle the rest of your renewal paperwork. If you renew in person at a Missouri license office, the vision test takes place there. If you renew by mail (which is available in some circumstances), you do not take a vision test at all — but mail renewal has strict may be able to access rules that most people do not meet.
Understanding what the test measures, what happens if you fail, and how to prepare will help you move through renewal without delays or unexpected rejections.
Key Takeaways
- Missouri's vision test measures visual acuity at 20 feet and checks your ability to see to the sides; you must score at least 20/40 in each eye, with or without correction.
- You can wear glasses or contact lenses during the test, and the examiner will note on your license if correction is required for driving.
- If you fail the vision test, you will not receive your renewed license that day; Missouri will mail you a notice explaining next steps and how to retest.
- Bring your current license, proof of residency, and any glasses or contacts you normally wear when you go in for renewal.
- Some medical conditions and medications can affect vision; if you have concerns, contact your eye doctor before your renewal appointment.
What the Missouri vision test measures
The vision test in Missouri checks two main things: how clearly you can see straight ahead, and how much you can see to the sides without moving your eyes. The acuity test — the part where you read letters on a chart — requires you to see at least 20/40 in each eye. That means at 20 feet away, you can see what a person with normal vision sees at 40 feet. This is not perfect vision, but it is the legal minimum Missouri accepts for driving.
The peripheral vision test checks whether you can detect movement and objects to the side. This matters because driving requires you to notice things in your side vision — other cars, pedestrians, road signs — without turning your head. If your side vision is too limited, you may fail this part even if your straight-ahead vision is fine.
The examiner uses a machine called a vision screener to run both tests. You look into the machine, focus on a target, and the machine records your results. The whole process takes a few minutes. The machine is automated, so the results do not depend on the examiner's judgment — either you meet the standard or you do not.
How correction (glasses and contacts) affects your test and license
You are allowed to wear glasses or contact lenses during the vision test. If you normally wear them to drive, you should wear them during the test. The examiner will note on your renewed license whether correction is required — this is printed as a restriction code on the back of your card.
If you pass the test while wearing glasses or contacts, your license will show that you must wear correction while driving. This is a legal requirement, not a suggestion. If you are stopped by police and you are not wearing the correction your license requires, you can be cited for a violation.
If you wear bifocals or progressive lenses, tell the examiner before the test starts. They may ask you to position your head in a specific way so the machine reads through the correct part of your lens. This takes an extra moment but ensures an accurate result.
What happens if you fail the vision test
If you do not meet Missouri's vision standard, you will not receive your renewed license on the day of your appointment. Instead, the examiner will give you a form explaining that you did not pass and what you need to do next. You will keep your current license, which remains valid until its expiration date.
Missouri will mail you a formal notice within a few days. The notice explains your options: you can schedule a retest at any Missouri license office, or you can have your eye doctor complete a Vision Report Form (DOR 4809) and send it directly to the Department of Revenue. The form must be signed by an optometrist or ophthalmologist and must state that you meet Missouri's vision standards for driving.
If you choose the retest route, you can schedule another appointment right away. There is no waiting period between attempts. If you choose the eye doctor route, your doctor fills out the form, you mail it to the address on the notice, and the Department of Revenue processes it. Once they receive and approve the form, they will issue your renewed license by mail.
Preparing for your vision test
If you wear glasses or contacts, bring them with you to your renewal appointment. Bring your current driver's license and proof of Missouri residency (such as a utility bill, lease, or bank statement). These documents are required for renewal itself, but they also help the examiner verify your identity and confirm your address.
If you have had recent changes to your vision — a new glasses prescription, cataract surgery, or a new eye condition — consider scheduling an eye exam before your renewal appointment. This is not required, but it can prevent a failed test and the delay that follows. If your eye doctor has concerns about your ability to drive safely, they can discuss this with you before you go in for renewal.
Some medications and medical conditions can affect vision temporarily. If you take medications that cause blurred vision or dizziness, or if you have a condition like diabetes that can affect your eyes, mention this to the examiner. They cannot override a failed test, but they can note the circumstances and may recommend that you follow up with your eye doctor.
Do not wear sunglasses into the license office, and do not wear them during the test. The vision screener needs to see your eyes clearly. If you have light sensitivity, let the examiner know — they can adjust the lighting or the machine's settings if possible.
Timeline and fees for renewal with vision testing
An in-person renewal appointment at a Missouri license office typically takes 15 to 30 minutes, including the vision test. The vision test itself is part of the renewal process and does not add a separate fee. You pay one renewal fee, which covers the license and all required testing.
The current renewal fee for a standard four-year driver's license in Missouri is $26.50. This fee does not change based on whether you pass the vision test on the first attempt or need a retest. If you fail and choose to have your eye doctor submit a Vision Report Form instead of retesting, there is no additional fee to the Department of Revenue, but your eye doctor may charge you for completing the form.
If you fail the vision test and schedule a retest, you do not pay a second renewal fee. You only pay for the retest appointment itself, which is $5.00 in Missouri. You will need to schedule a new appointment and return to a license office.
Mail renewal and vision testing
Missouri allows some drivers to renew by mail without taking a vision test in person. However, the may be able to access rules are narrow. You can renew by mail only if your current license is not expired, you have not had any address changes, you do not need to update your photo, and you do not have any medical conditions or restrictions that require reassessment.
If you are unsure whether you may have access to for mail renewal, contact the Missouri Department of Revenue before you attempt it. If you submit a mail renewal process and you do not meet the requirements, the process will be rejected and you will have to start over with an in-person appointment. This creates a delay, so it is better to verify first.
Most drivers renew in person because their circumstances change — they move, their photo expires, or they want to update information. If you fall into this group, you will take the vision test at your appointment.
Frequently Asked Questions
Can I wear my reading glasses during the vision test?
If you normally wear reading glasses only for close work and not for driving, tell the examiner. They may ask you to remove them for the test. If you wear bifocals or progressive lenses that you use for driving, keep them on. The key is that the test should reflect how you actually see while driving.
What if I have had eye surgery since my last license renewal?
Tell the examiner about any recent eye surgery before the test begins. Conditions like cataract surgery, LASIK, or corneal transplants can affect your vision in ways that take time to stabilize. If your vision has changed significantly, your eye doctor can help you understand whether you will pass the test, and you can schedule your renewal appointment accordingly.
Do I have to pass the vision test to renew, or can I get a restricted license?
You must meet Missouri's minimum vision standard to drive at all. There is no restricted license category that allows you to drive without meeting the vision requirement. If you do not pass, your options are to retest, have your eye doctor submit a Vision Report Form, or wait until your vision improves and try again.
How long does it take to get my license after I pass the vision test?
If you pass the vision test at your in-person appointment, you will receive a temporary paper license that day. Your permanent plastic license will arrive by mail within 7 to 10 business days. The temporary license is valid for driving when ready.
What if I fail the vision test but I believe the machine made a mistake?
You can request a retest at any time. Schedule a new appointment at a Missouri license office and take the test again. If you fail a second time and believe there is a problem, have your eye doctor examine you and submit a Vision Report Form. Your doctor's professional assessment will override the machine results if they state that you meet the vision standard for driving.
