If you hold a commercial driver’s license and drive only inside your home state, you almost always need a DOT medical card. The intrastate CDL medical card requirement applies to every non-excepted intrastate driver, and the only way out is if your state has specifically classified your type of commercial driving as “excepted.” Federal rules force each CDL holder to declare which category they fit into, and that declaration is what determines whether a medical certificate is mandatory.
The Four Categories You Choose From
When you apply for or renew a CDL, your state licensing agency makes you self-certify into one of four categories. Two of them apply to intrastate drivers.
- Non-excepted intrastate: you drive only within your home state and must meet your state’s medical certification rules. You need a medical card.
- Excepted intrastate: you drive only within your home state in an operation your state has specifically exempted from medical certification. You do not need a card.
- Non-excepted interstate: you cross state lines and must meet federal DOT medical standards.
- Excepted interstate: you cross state lines in a federally excepted operation and don’t need a card.
If your driving falls into both excepted and non-excepted intrastate work at different times, you have to certify as non-excepted intrastate and carry a medical card.1Federal Motor Carrier Safety Administration.

Who Actually Qualifies as Excepted Intrastate
Each state defines its own list of excepted intrastate operations, so the specifics vary from one state to the next. Common examples include certain government employees driving official vehicles, farm vehicle operators hauling agricultural products short distances, and in some states, school bus drivers.1Federal Motor Carrier Safety Administration. How to Determine Commercial Motor Vehicle (CMV) Operation Self-Certification Category
Do not guess. If you think your work might qualify, call your state’s CDL licensing agency and confirm before you certify. Assuming you’re excepted when you aren’t leads to a downgraded CDL and federal fines.
Getting the Medical Card
The medical card comes from passing a DOT physical performed by a medical examiner listed on FMCSA’s National Registry of Certified Medical Examiners. Not every doctor qualifies for this. You can search by city, state, or zip code at nationalregistry.fmcsa.dot.gov.2Federal Motor Carrier Safety Administration. National Registry of Certified Medical Examiners
DOT physicals generally cost between $50 and $200. Chiropractors and urgent care clinics tend to be cheaper than specialist offices. Insurance usually doesn’t pay for it, because a DOT physical is treated as an occupational requirement rather than a diagnostic visit. Any follow-up testing the examiner orders is extra, and employer drug screening is a separate charge that runs another $30 to $85.
Bring your eyeglasses or hearing aids if you use them, a list of every medication you take with dosages, and your medical history. If you’re insulin-dependent, bring the Insulin-Treated Diabetes Mellitus Assessment Form filled out by your treating clinician. Better documentation, faster appointment.
What the Exam Actually Checks
The examiner is looking at your ability to safely operate a commercial vehicle. Vision, hearing, cardiovascular health, neurological function, and a general physical exam are all covered. Urinalysis is part of the visit, but it screens for kidney problems and diabetes markers, not drugs. Employer drug and alcohol testing is a separate program.3Federal Motor Carrier Safety Administration. What Substances Are Tested?
A few standards catch people out more often than others. Blood pressure is the biggest one. Below 140/90 gets you a full two-year card. Stage 1 (140–159/90–99) gets a one-year card. Stage 2 (160–179/100–109) earns a one-time three-month temporary card, with a one-year card possible if you bring readings under 140/90 within that window. Stage 3 (180/110 or higher) is disqualifying until treatment brings you under 140/90, after which you can be certified in six-month intervals. Drivers already on blood pressure medication should expect annual recertification at most.4Federal Motor Carrier Safety Administration. Section 391.41(b)(6): Driver Safety and Health-Medical Requirements
Insulin-treated diabetes is no longer an automatic disqualification. Since a 2018 federal rule change, a certified medical examiner can evaluate and certify you directly using the Insulin-Treated Diabetes Mellitus Assessment Form completed by your treating clinician, with no separate federal exemption required. Vision requires 20/40 acuity in each eye (with or without correction) and at least a 70-degree horizontal field per eye; drivers who can’t meet that in their worse eye may still qualify under the alternative vision standard in 49 CFR 391.44. Any history of epilepsy or a condition likely to cause loss of consciousness is disqualifying, and there is no federal exemption program for seizure disorders in commercial driving.5eCFR. 49 CFR 391.41 – Physical Qualifications for Drivers
Submitting the Card to Your State
Once you pass, the examiner uploads your results to FMCSA’s National Registry. That is not enough. You still have to send a copy of the medical examiner’s certificate to your state licensing agency. Depending on the state, that’s an online upload, mail, or an in-person visit.6Federal Motor Carrier Safety Administration. Medical
Do it right away. If your state doesn’t have a current certificate on file, your CDL record eventually flips to “not certified,” and the downgrade clock starts.
How Long the Card Is Good For
A standard medical certificate is valid for two years. Hypertension stable on treatment, heart disease, or insulin-treated diabetes drops that to one year. Anything the examiner thinks needs closer monitoring, such as Stage 2 or 3 blood pressure or sleep disorders, drops it further. The expiration date is printed on the card, and it’s on you to schedule the next physical and submit the new certificate before the old one expires.7Federal Motor Carrier Safety Administration. For How Long Is My Medical Certificate Valid?
What Happens If You Let It Lapse or Skip It
The moment your certificate expires, your state marks your CDL as “not certified.” Federal rules then require the state to complete a CDL downgrade within 60 days. A downgrade removes your commercial privileges and converts you to a standard non-commercial license.8eCFR. 49 CFR 383.73 – State Procedures
Some states move faster than the federal 60-day ceiling. A handful begin the downgrade within 10 days of expiration; others give 30 or 55 days of notice. If your CDL stays downgraded for an extended period, often 12 months, many states will make you retake the CDL skills test to get it back, not just submit a new medical certificate.
Driving a commercial vehicle without valid medical certification also exposes you to federal civil penalties. A driver can be fined up to $4,812 per violation, and a carrier that lets a driver operate without a current certificate faces fines up to $19,246 per violation.9Federal Register. Revisions to Civil Penalty Amounts, 2025 Those amounts are adjusted annually for inflation.
A Note on Drug and Alcohol Testing
New CDL holders sometimes confuse the medical card with drug and alcohol testing. They aren’t the same program. The DOT physical is a medical fitness exam. DOT drug and alcohol testing is an employer-run program covering pre-employment, random, post-accident, and reasonable-suspicion testing, with a standard panel that screens for marijuana, cocaine, opiates, amphetamines, and PCP.3Federal Motor Carrier Safety Administration. What Substances Are Tested? Passing your physical does not cover you for that; failing a drug test does not affect your medical card.
