Quick answer
Renew a medical tint exemption by getting an updated physician certificate before the old one expires, then refiling any state form or permit your state requires. ShadedMD certificates are valid for one year, and renewal is done online: a short questionnaire and a fresh physician review (physicians aim to review within 24 to 48 hours), with a new signed certificate emailed if you are approved, for the same flat $129.
Key takeaways
- ShadedMD certificates are valid for one year. State approvals follow their own rules, and some end when the vehicle is sold.
- Start the renewal two to four weeks before expiration so there is no gap in coverage.
- A renewal is a new physician review. A long-term condition is often still present at renewal, but the physician evaluates the case again and decides.
- If your state issued a permit or decal, you may need to refile the state paperwork with the new certificate. Check your state DMV's current requirements.
- An expired exemption is the same as no exemption during a traffic stop, so put the date on your calendar.
How long exemptions last
There is no single national rule. The physician certificate and the state approval can have different lifespans:
- Physician certificates are typically valid for a set period. ShadedMD certificates are valid for one year from the date of issue, with the expiration printed on the document.
- State permits or decals follow the state's schedule, and some are tied to the vehicle. Florida's medical exemption certificate becomes void when the vehicle is sold or transferred, and Virginia's sun-shading authorization lasts until the vehicle is sold or the medical condition no longer exists.
- Certificate-in-vehicle states generally rely on the physician document alone, so the certificate's expiration is the date that matters.
Check your certificate and any state paperwork for both dates and use the earlier one as your deadline. Start with your state's page in the state directory, then confirm on your state DMV's website.
Why exemptions expire at all
Conditions change. Someone on a photosensitizing medication for six months does not need a permanent exemption. Someone whose photophobia resolved after eye surgery may no longer qualify. Expiration dates let physicians reconfirm that the medical need is still current, which keeps the exemption credible with police and state agencies. For drivers with lifelong conditions such as lupus, albinism, or porphyria, the medical need often continues, but renewal is still a physician decision, not a formality.
How to renew with ShadedMD
- 1Start the renewal online. Go to /qualify and complete the medical questionnaire. It takes about 5 minutes. Note any changes in your condition, treatment, or medications since your last certificate.
- 2Physician review. A physician licensed in your state evaluates your case individually, just like the first time.
- 3Receive your new certificate. Physicians aim to review within 24 to 48 hours. If you are approved, a signed certificate with a new Recommendation ID and a fresh one-year validity is emailed to you.
- 4Refile state paperwork if needed. If your state requires a form or permit, check your state DMV for what to submit. Some forms have their own timing rules: New York's, for example, requires the medical examination to be within 60 days of when the form is submitted.
- 5Swap the copies in your car. Replace the old certificate in the glovebox and update the backup on your phone.
Renewal pricing is the same flat $129, one time, with no subscription. You are only charged at checkout, and the 30-day money-back guarantee applies: if the physician cannot approve the renewal, you get a full refund.
When to start
Two to four weeks before expiration is ideal. That leaves time for the physician review, and, in form states, time for the state to process the renewal before the old permit lapses. If your state mails a permit, give it the full four weeks.
Do not wait for a traffic stop to remind you. An expired certificate gives an officer no reason to waive a citation, and you would then be paying a fine plus the renewal. Put the expiration date in your phone calendar the day your certificate arrives, with a reminder one month out. Our article on what to keep in your car suggests checking the date twice a year.
What can change at renewal
A renewal is a new evaluation, not a rubber stamp. A few things may be different from the first time:
- Your condition improved. If the medical need has resolved, the physician may not be able to approve a renewal. The 30-day guarantee still applies.
- Your condition changed. A new diagnosis or a new photosensitizing medication should be included in the questionnaire. It often strengthens the case. See medical conditions that qualify.
- Your state changed its rules. States occasionally revise tint laws or exemption procedures. Check your state DMV's current requirements at renewal time.
- You changed vehicles or states. Both can affect whether the exemption carries over. Read moving to another state with a tint exemption if that applies.
Renew in minutes
Renewing with ShadedMD is the same simple process as the first certificate: no appointment, no office visit, no waiting room. A physician licensed in your state reviews every renewal individually, and physicians aim to finish within 24 to 48 hours. This is general information, not medical or legal advice. Start your renewal whenever your expiration date is within a month.
Frequently asked questions
How long is a ShadedMD certificate valid?
One year from the issue date. The expiration date is printed on the certificate.
Does renewal cost the same as the first certificate?
Yes. Renewal is the same flat $129, one time. There is no subscription and no hidden fee, and you are only charged at checkout.
Do I have to redo the questionnaire?
Yes, because a renewal is a fresh physician review. The questionnaire takes about 5 minutes, and answering it with your current information helps the physician make an accurate decision.
Will I need to refile my state form?
It depends on the state. If your state issued a permit or decal with its own expiration, you may need to refile with the new certificate. Check your state DMV's requirements.
What happens if I let my exemption lapse?
During the gap, tint darker than your state's standard limit is generally treated as illegal tint. Renew as soon as possible and keep the new certificate in the car. If you were cited during the gap, a renewed certificate may still help in court, but that is not guaranteed.
Can I renew early?
Yes. Starting two to four weeks before expiration is recommended so the new certificate and any state paperwork are in place before the old one lapses.
