Florida CDL self-certification is the declaration every commercial driver in the state must file with the Florida Department of Highway Safety and Motor Vehicles (FLHSMV) stating which of four operating categories describes their driving and, if required by that category, providing a current Medical Examiner’s Certificate. You complete it by choosing the right category, getting a DOT physical if your category requires one, and submitting the paperwork to the FLHSMV online, in person, or by fax or mail. It is not a one-time task. Your certification and medical card have to stay current the entire time you hold a CDL.
Pick the Right Category
Florida uses the four federal categories, labeled A through D. You pick one, and picking wrong matters: the state can suspend or revoke your CDL if you are caught driving in a category different from the one you certified.1Federal Motor Carrier Safety Administration. Medical
- Category A — Non-Excepted Interstate. You drive across state lines or expect to, and you must meet all federal medical qualification standards. This is the most common choice, and it requires a Med Card.2Federal Motor Carrier Safety Administration. How to Determine Which of the 4 Categories of CMV Operation to Self-Certify
- Category B — Excepted Interstate. You cross state lines but only perform operations exempted from federal medical rules, such as certain government driving, school bus operation, or emergency response by fire or rescue vehicles. No Med Card required.3eCFR. 49 CFR 390.3 – General Applicability
- Category C — Non-Excepted Intrastate. You drive only inside Florida and must meet the state’s medical certification standards. Med Card required.2Federal Motor Carrier Safety Administration. How to Determine Which of the 4 Categories of CMV Operation to Self-Certify
- Category D — Excepted Intrastate. You drive only inside Florida and only perform operations Florida has exempted from medical certification. No Med Card required.2Federal Motor Carrier Safety Administration. How to Determine Which of the 4 Categories of CMV Operation to Self-Certify
If you are not sure whether your driving counts as interstate or intrastate, the FLHSMV advises intrastate drivers to consider certifying in Category A when eligible. It gives you flexibility to cross state lines without recertifying first. Drivers under 21 and drivers with certain medical conditions who lack a federal medical variance cannot certify in Category A.4Florida Highway Safety and Motor Vehicles. CDL Medical Information
One thing you cannot do is opt out. The FLHSMV states that CDL holders can no longer claim exemption from medical certification simply because they are not currently operating in non-excepted commerce. If you hold the license, you either maintain the certification or the state will move you to a non-commercial license.4Florida Highway Safety and Motor Vehicles. CDL Medical Information
Get Your Medical Examiner’s Certificate
If you are certifying in Category A or C, you need a valid Med Card, sometimes called a DOT card, before you can complete your self-certification.
The Med Card comes from a DOT physical performed by an examiner listed on the FMCSA’s National Registry of Certified Medical Examiners. Interstate drivers must use a registered examiner.5Federal Motor Carrier Safety Administration. National Registry of Certified Medical Examiners You can search by ZIP code at nationalregistry.fmcsa.dot.gov.6FMCSA National Registry. Welcome to the National Registry of Certified Medical Examiners Most health insurance will not cover the exam. Expect to pay somewhere between $50 and $225 out of pocket. If you pass, the examiner issues a Medical Examiner’s Certificate on Form MCSA-5876.7Federal Motor Carrier Safety Administration. Medical Examiner’s Certificate (MEC), Form MCSA-5876
A Med Card is good for a maximum of 24 months. The examiner can issue a shorter card if a condition needs monitoring. High blood pressure is the most common reason drivers walk out with a one-year card instead of a two-year one.8Federal Motor Carrier Safety Administration. DOT Medical Exam and Commercial Motor Vehicle Certification Drivers with insulin-treated diabetes or certain vision deficiencies may also be limited to annual exams.9eCFR. 49 CFR 391.45 – Persons Who Must Be Medically Examined and Certified Whatever expiration date your card shows, that is the date you are working against.
As of June 23, 2025, medical examiners send DOT exam results to the FMCSA electronically. That does not replace your job of filing the self-certification with Florida. The federal database updates on its own, but the state still needs your paperwork.
Submit Your Self-Certification to the FLHSMV
Once you have your Med Card, or you have confirmed you fall into an excepted category, there are three ways to get the certification on file.
Online
The fastest option is the FLHSMV’s CDL Medical Self-Certification portal at services.flhsmv.gov/cdlmedcert/. You will need your Florida CDL number and the details from your Med Card.
In Person
Visit any Florida driver license office or tax collector’s office that provides driver license services. Bring the original Med Card and complete the self-certification on site.
By Fax or Mail
You can fax or mail a completed self-certification affidavit and a copy of your Med Card to the FLHSMV Commercial Driver License Section. Contact the FLHSMV for the current fax number and mailing address; they change periodically.
Whichever route you use, submit as soon as you have the card in hand. A gap between the exam and the state’s receipt of your paperwork is a gap where you show as non-compliant.
Keep It Current
Self-certification is not file-and-forget. Update your record any time one of these happens:
- Your Med Card is about to expire. Schedule your next DOT physical and submit the new certificate before the current one runs out. A few weeks of cushion protects you against scheduling delays.
- Your type of driving changes. If you certified as B or D and start driving in non-excepted commerce, you have to recertify in the new category and provide a Med Card.4Florida Highway Safety and Motor Vehicles. CDL Medical Information
- A health condition develops or worsens. If an injury or illness impairs your ability to drive as usual, federal rules require a new medical exam regardless of when your current card expires.9eCFR. 49 CFR 391.45 – Persons Who Must Be Medically Examined and Certified
What a Lapse Costs
When your Med Card expires, or when the FMCSA notifies Florida that your medical certification has been invalidated, the FLHSMV marks your CDL record “not-certified.” From that point, the state has 60 days to complete a downgrade. A downgrade removes your commercial driving privileges and leaves you with a standard non-commercial license.10eCFR. 49 CFR 383.73 – State Procedures
The FLHSMV confirms that failing to maintain a valid Med Card on file will result in denial of CDL issuance or renewal, and may lead to full CDL disqualification.4Florida Highway Safety and Motor Vehicles. CDL Medical Information Driving a commercial vehicle after a downgrade means driving without the correct license class, which brings citations and court dates with it.
Getting your CDL privileges back after a downgrade means passing a new DOT physical, submitting the new Med Card to the FLHSMV, and completing any reinstatement requirements the state imposes. There is usually a fee. Renewing on time is cheaper than any of it.
If You Have a Condition That Might Disqualify You
A physical impairment does not automatically end your CDL. The FMCSA runs a Skill Performance Evaluation (SPE) Certificate Program for interstate drivers with conditions such as a missing limb or limited mobility. If you qualify and pass a driving evaluation, the SPE certificate lets you drive commercially across state lines. Drivers who use a prosthetic must be fitted with the correct device during the evaluation.11Federal Motor Carrier Safety Administration. Skill Performance Evaluation Certificate Program
Drivers with insulin-treated diabetes or vision that falls short of federal thresholds may qualify for federal medical exemptions, though these usually require annual exams rather than the standard two-year cycle.9eCFR. 49 CFR 391.45 – Persons Who Must Be Medically Examined and Certified Talk to a certified medical examiner before assuming a condition ends your certification path.
Who Doesn’t Have to Self-Certify
Florida law exempts some commercial-sized-vehicle drivers from needing a CDL at all, and no CDL means no self-certification obligation. The exemptions include drivers of authorized emergency vehicles, active military personnel operating military vehicles, farmers hauling agricultural products within 150 miles of their farm, and drivers of recreational vehicles, among others.12The Florida Legislature. Florida Statutes 322.53 – Classification of Drivers’ Licenses If you fall into one of these categories and do not hold a CDL, the certification rules do not touch you. If you hold a CDL anyway, they do — whether you are using the license commercially or not.
