Missouri requires a vision test at renewal only if you did not pass one at your last visit or if the DMV has flagged your record
Missouri does not automatically require a vision test every time you renew your driver's license. The state uses a selective system: you will take a vision test at renewal only if one of three conditions applies. First, you failed a vision screening at your previous renewal or license transaction. Second, your medical records show a condition that affects sight. Third, you are over 70 years old and renewing in person at a DMV office.
If none of these explore to you, you may renew by mail or online without a vision test. The Missouri Department of Revenue will notify you in writing if a vision test is required before your renewal appointment. This notice arrives with your renewal reminder or in a separate letter if your record has been flagged.
Understanding whether you need a test before you arrive at the DMV saves time and prevents a failed renewal. The rules differ slightly depending on your age and how you choose to renew, so checking your renewal notice is the first step.
Key Takeaways
- You need a vision test at renewal only if you failed one previously, have a medical condition affecting sight, or are over 70 and renewing in person.
- Missouri will send you written notice if a vision test is required; check your renewal reminder letter before your appointment.
- The vision test measures visual acuity and peripheral vision using a machine called a vision screener, and takes about two minutes.
- If you fail the vision test, you can retake it when ready at most DMV offices, but you cannot renew your license until you pass.
- Drivers over 70 renewing by mail do not need a vision test, but those renewing in person at an office must take one.
Who must take a vision test during Missouri license renewal
Missouri groups drivers into categories based on age and renewal history. Drivers under 70 with no failed vision tests on record and no medical flags do not need a vision test, regardless of how they renew. Drivers over 70 who renew in person at a DMV office must take a vision test as part of the renewal process. Drivers over 70 who renew by mail are exempt from the vision test requirement.
If you have a medical condition documented in your record—such as diabetic retinopathy, macular degeneration, or a recent eye surgery—Missouri may require a vision test even if you are under 70 and have never failed one before. The DMV reviews your driving record and medical history when processing your renewal process. If a concern is flagged, you will receive notice before your appointment.
Drivers who failed a vision test at any previous renewal or license transaction must pass a new vision test before renewing. This includes tests failed at your last renewal, at a license replacement, or during a medical review. Missouri does not waive this requirement based on time elapsed or improved vision; you must test again to renew.
What the Missouri vision test measures and how it works
The Missouri vision test checks two main things: visual acuity (how clearly you see) and peripheral vision (what you can see to the sides without moving your eyes). The test uses an automated vision screener machine, similar to equipment found in eye doctors' offices. You look into the machine, focus on a target, and the screener records your results. The entire test takes about two minutes per eye.
Visual acuity is measured on the standard 20/40 scale for driver's licenses in Missouri. This means you must see at 20 feet what a person with normal vision sees at 40 feet. If you wear glasses or contact lenses, you take the test wearing them. Missouri does not test uncorrected vision; if you need correction to meet the standard, you must wear it while driving and during the test.
Peripheral vision is tested to may support you can see hazards approaching from the sides. The screener measures how far to the left and right you can detect movement or objects. Missouri requires a minimum horizontal field of vision of 140 degrees combined (70 degrees on each side). If you fail either component—acuity or peripheral vision—you cannot renew until you pass.
Passing and failing the vision test
If you pass the vision test, the results are recorded when ready and your renewal proceeds. You will receive your renewed license by mail within 7 to 10 business days if you renewed in person, or within the timeframe specified if you renewed online or by mail.
If you fail the vision test, you have options. You can retake the test when ready at most Missouri DMV offices at no additional fee. Many drivers pass on a second attempt due to nervousness or difficulty with the machine on the first try. If you fail a second time, you must see an eye care professional—an optometrist or ophthalmologist—and obtain a signed statement confirming that your vision meets Missouri's standards. You then submit this statement to the DMV along with a renewal process.
If you cannot meet the 20/40 standard even with correction, Missouri may issue a restricted license instead of a full license. Restrictions might include daytime-only driving, no highway driving, or a requirement to wear corrective lenses at all times. The DMV will explain any restrictions before issuing your license.
How to prepare for your vision test
If you know a vision test is required, bring your current glasses or contact lenses to your DMV appointment. Do not rely on the DMV to have backup pairs or to allow you to borrow equipment. Wear your correction during the test if you normally wear it while driving. If you wear bifocals or progressive lenses, let the DMV staff know; they may adjust how you position yourself at the screener.
Get a good night's sleep before your appointment and avoid eye strain the day of your test. Do not spend hours on screens when ready before arriving at the DMV. If you have had recent eye surgery or a change in your prescription, consider scheduling your renewal after you have fully recovered or after your new glasses have arrived.
If you are unsure whether you will pass, schedule an eye exam with an optometrist or ophthalmologist before your DMV appointment. This costs money out of pocket, but it prevents a failed test at the DMV and gives you time to obtain a corrective statement if needed. Many vision insurance plans cover annual exams, so check your coverage first.
Renewal methods and vision test requirements by age
| Driver Age | Renewing In Person | Renewing by Mail | Renewing Online |
|---|---|---|---|
| Under 70, no prior failed test | No vision test required | No vision test required | No vision test required |
| Under 70, prior failed test | Vision test required | Vision test required (must visit office) | Vision test required (must visit office) |
| Over 70 | Vision test required | No vision test required | Not available for this age group |
| Medical flag on record | Vision test required | Vision test required (must visit office) | Not available |
Drivers under 70 with no failed vision tests can renew online through the Missouri DMV website, by mail, or in person. Online renewal is the fastest option and requires no vision test. Mail renewal takes 7 to 10 business days and also requires no vision test if you have a clean record.
Drivers over 70 can renew by mail without a vision test, but if you choose to renew in person at a DMV office, a vision test is mandatory. If you have a prior failed test or a medical flag, you must renew in person and take a vision test, regardless of your age. Online renewal is not available for drivers over 70 or those with medical flags.
What to bring to your vision test appointment
Bring your current driver's license or state ID, proof of residency (utility bill, lease, or bank statement dated within 90 days), and your Social Security card or a document showing your Social Security number. If you have changed your name since your last license, bring a certified copy of the document proving the change (marriage certificate, divorce decree, or court order).
Bring your glasses or contact lenses if you wear them. Bring your insurance card if you have vision insurance, though the DMV does not bill insurance for the vision test itself. If you are renewing due to a medical condition or prior failed test, bring any documentation from your eye care provider that supports your current fitness to drive.
Do not bring expired documents or documents with names that do not match your current legal name. The DMV will reject your renewal if your identity documents are incomplete or inconsistent. Arrive 10 to 15 minutes early to allow time for check-in, especially if you are renewing in person for the first time.
Frequently Asked Questions
Can I renew my Missouri license online if I am over 70?
No. Drivers over 70 can renew by mail or in person at a DMV office, but online renewal is not available for this age group. If you renew in person, you must take a vision test. If you renew by mail, no vision test is required.
What happens if I fail the vision test twice?
After two failures, you must see an eye care professional and obtain a signed statement confirming your vision meets Missouri's standards. You submit this statement with your renewal process. If you cannot meet the 20/40 standard even with correction, Missouri may issue a restricted license with limitations such as daytime-only driving.
Do I need a vision test if I renew by mail?
Only if you have a prior failed test, a medical flag on your record, or are over 70 and choose to renew in person instead. If you are under 70 with a clean record, mail renewal requires no vision test. If you do have a prior failed test, you must visit an office in person to take the test before renewing by mail.
How long does the vision test take?
The vision test itself takes about two minutes. Your entire DMV appointment, including check-in, the vision test, and processing, typically takes 15 to 30 minutes depending on how busy the office is.
Can I wear my contact lenses during the vision test?
Yes. You take the vision test wearing whatever correction you normally wear while driving. If you wear contact lenses, wear them to your appointment. If you wear glasses, bring them. Missouri tests your vision as you actually see while driving, not your uncorrected vision.
