A DOT med card is a certificate proving that a commercial vehicle driver is physically fit to operate on public roads. Officially called the Medical Examiner’s Certificate (Form MCSA-5876), it’s issued after a driver passes a physical exam conducted by a federally certified medical examiner. Without one, you can’t legally drive a commercial motor vehicle in interstate commerce.
Who Needs a DOT Med Card
All commercial drivers operating vehicles in interstate commerce with a gross vehicle weight rating over 10,000 pounds are required to obtain and maintain a valid Medical Examiner’s Certificate. This covers most truck drivers, bus drivers, and anyone hauling freight or passengers across state lines in a vehicle above that weight threshold.
The requirements get more specific depending on your situation. The Federal Motor Carrier Safety Administration (FMCSA) breaks drivers into four categories based on two factors: whether you drive across state lines (interstate) or only within one state (intrastate), and whether you’re “excepted” or “non-excepted” from medical requirements. Interstate non-excepted drivers must meet federal DOT medical standards. Intrastate non-excepted drivers follow their own state’s medical requirements, which often mirror federal rules closely. Excepted drivers in either category, such as certain farm vehicle operators, may not need the card at all. Your state’s driver licensing agency can help you determine which category applies.
What the Physical Exam Covers
The DOT physical is a head-to-toe evaluation designed to catch conditions that could impair your ability to safely control a large vehicle. It’s more thorough than a standard checkup, with specific pass/fail thresholds for vision, hearing, blood pressure, and other health markers.
Vision standards are precise. You need at least 20/40 acuity in each eye individually, and 20/40 with both eyes together, with or without corrective lenses. Your horizontal field of vision must reach at least 70 degrees in each eye. You also need to correctly identify standard red, green, and amber traffic signal colors.
The exam includes a urine test to check for sugar, which screens for uncontrolled diabetes. If your blood pressure is elevated, you may need a clearance letter from your primary care doctor before the examiner can certify you. The examiner will also evaluate your cardiovascular health, neurological function, musculoskeletal condition, and general physical fitness for the demands of commercial driving.
Conditions That Can Disqualify You
Four conditions are specifically disqualifying under federal regulation: hearing loss beyond the allowed threshold, vision loss that falls below the standards above, epilepsy, and insulin-dependent diabetes. Drivers with diabetes requiring insulin or those who don’t meet vision standards aren’t permanently barred, but they must apply for and receive a federal exemption before they can be certified.
Other conditions won’t automatically disqualify you but may require extra documentation. If you’ve been diagnosed with sleep apnea, for instance, you’ll need to bring a compliance report showing at least 30 days of CPAP use, with usage of more than four hours per night at least 70 percent of the time. Seizure disorders, cardiac conditions, and use of certain psychiatric medications all require supporting records from your treating physician or specialist.
How to Get Your Card
The exam must be performed by a medical examiner listed on the FMCSA’s National Registry of Certified Medical Examiners. Not every doctor qualifies. These examiners have completed specialized training on the physical demands of commercial driving and the federal standards involved. You can search for a certified examiner near you by city, state, or zip code on the FMCSA’s National Registry website.
The exam typically costs between $95 and $140, though prices vary by location and provider. Most urgent care clinics and occupational health centers that offer DOT physicals fall in this range. Insurance generally does not cover it since it’s an occupational requirement, not a diagnostic visit.
If you have any pre-existing conditions, bring documentation to your appointment. This includes CPAP compliance reports for sleep apnea, neurology reports for seizure history, cardiac records, recent HbA1C results if you have diabetes, and details about any psychiatric medications. Having these ready prevents delays and return visits.
What You Receive After the Exam
If the examiner determines you meet the physical qualification standards, they’ll complete and hand you the Medical Examiner’s Certificate, Form MCSA-5876. This is the card itself: a document you’re required to carry and, in most states, submit to your state driver licensing agency to keep your commercial driver’s license active.
The examiner also fills out a longer form, the Medical Examination Report (Form MCSA-5875), which is the detailed record of the full exam. You don’t need to carry this, but the examiner submits results to the FMCSA electronically, so your certification status is linked to your driving record.
How Long It Stays Valid
A standard DOT med card is valid for up to 24 months. However, the examiner can issue a shorter certification period if your health warrants more frequent monitoring. Drivers with controlled high blood pressure, for example, often receive a one-year card instead of two. When your card expires, you need a new physical exam and a new certificate to keep driving commercially. There’s no grace period: driving with an expired card puts your CDL status at risk and can result in being placed out of service during a roadside inspection.
