How long is a DOT medical card good for?
A DOT medical examiner's certificate is valid for up to 24 months. The examiner can issue a shorter card, often one year or less, when a condition such as high blood pressure or insulin-treated diabetes needs closer monitoring. Confirm current standards with FMCSA, and renew before the expiration date to avoid losing driving privileges.
The DOT physical is a short exam with big consequences. Pass it and you get a medical examiner's certificate, the "medical card," that keeps you legal to drive. Let it lapse and your truck sits, no matter how good the load is. Here is what to expect and how to avoid surprises.
Who needs a medical card
Federal medical standards (49 CFR 391.41 through 391.49) apply to drivers of commercial motor vehicles in interstate commerce. That generally includes:
- All CDL drivers in non-excepted interstate operations
- Non-CDL drivers of vehicles with a gross weight or rating over 10,001 pounds, which covers many hotshot and box truck operations
- Drivers of placarded hazmat vehicles and certain passenger vehicles
Intrastate drivers follow state rules, which are often similar but not identical.
Who can do the exam
Only a medical examiner listed on the National Registry of Certified Medical Examiners (NRCME) can perform a DOT physical. That might be a physician, nurse practitioner, physician assistant, chiropractor or other licensed provider who completed FMCSA training and testing. Before you book, search the registry or ask the clinic to confirm.
Carriers must verify that the examiner is on the registry and keep proof in the driver qualification file.
What happens at the exam
The visit usually takes under an hour. Expect:
- Health history form. You complete the driver section of the exam report. Answer honestly. Leaving out a condition or medication can create bigger problems later.
- Vision test. The federal standard requires at least 20/40 in each eye and with both eyes, with or without correction, a horizontal field of vision of at least 70 degrees in each eye, and the ability to recognize red, green and amber.
- Hearing test. Usually a forced whisper test at about five feet, or an audiometer test. Hearing aids are allowed if you wear them while driving.
- Blood pressure and pulse.
- Urinalysis. This checks for signs of conditions such as diabetes or kidney problems. It is not a drug test. The DOT drug test is separate.
- Physical exam. Eyes, ears, heart, lungs, abdomen, spine, extremities and neurological checks.
The examiner then decides: qualified for up to 24 months, qualified for a shorter period, determination pending, or not qualified.
Conditions that commonly shorten a card
High blood pressure
Blood pressure is the most common reason drivers get a shorter card. Under FMCSA's guidance, examiners generally issue a one-year card for mildly elevated readings, a short temporary card for higher readings while you get treatment, and do not certify at very high readings until they come down. Exact ranges are in FMCSA guidance, so check with your examiner.
Tips: take your medication as prescribed on exam day, avoid caffeine and nicotine beforehand, and arrive early so you are not rushing.
Diabetes
Diabetes controlled by diet or oral medication is generally handled by examiner judgment. Insulin-treated diabetes is allowed under a 2018 rule, but the driver needs a completed assessment form from the treating clinician before the exam, and the card is limited to a maximum of 12 months. Confirm current forms and timing with FMCSA.
Vision in one eye
FMCSA created an alternative vision standard that lets some drivers who do not meet the vision standard in one eye be certified, with an evaluation by an eye specialist first. Ask your examiner and check FMCSA for current details.
Sleep apnea, heart conditions, medications
These are judgment calls. Bring records: a CPAP compliance report, a cardiologist's clearance letter, a medication list with doses. Missing paperwork is a leading cause of a "determination pending" result and a return visit.
Medical card checklist
Before the exam: - [ ] Confirm the examiner is on the National Registry - [ ] Bring your driver's license and glasses, contacts or hearing aids - [ ] Bring a list of all medications and dosages - [ ] Bring specialist records for any ongoing condition (CPAP report, cardiology letter, insulin assessment form) - [ ] Take regular medications as prescribed
After the exam: - [ ] Get a copy of your medical examiner's certificate - [ ] Give a copy to your carrier for the DQ file (or file it yourself if you are the carrier) - [ ] Confirm your state licensing agency has your updated medical status if you hold a CDL - [ ] Put the expiration date in your calendar with a 30- and 60-day reminder
How the card reaches your state
CDL holders must also self-certify their type of operation with their state and keep their medical status current. FMCSA has been moving to electronic transmission of exam results from examiners to FMCSA and then to state licensing agencies. That changes how drivers submit proof and whether a paper card is the primary record. Rules on whether you must still carry the paper card or submit it yourself have been changing, so confirm the current process with your state licensing agency and FMCSA. Keeping a copy in the truck costs nothing.
Worked example: plan around the expiration
Say your card expires on March 15 and you are an owner-operator running 2,500 miles a week.
- Book the exam in mid-January, about 60 days out.
- If the exam goes smoothly, you are done with weeks to spare.
- If the examiner needs a specialist letter, you still have about eight weeks to get it.
Compare that to booking on March 10. A pending result could leave you unable to drive. At a hypothetical $1,500 of net profit per week, a two-week gap costs about $3,000 plus any loads you had to cancel. Plan home time and routes around the appointment, and use the hours of service calculator to fit it into your schedule.

Frequently asked questions
Who needs a DOT medical card?
Drivers of commercial motor vehicles in interstate commerce generally need one, including many non-CDL drivers of vehicles over 10,001 pounds. CDL holders must also keep their medical certification status current with their state licensing agency.
Can any doctor do a DOT physical?
No. The exam must be done by a medical examiner listed on FMCSA's National Registry of Certified Medical Examiners. A card from an examiner who is not on the registry is not valid.
What happens if my medical card expires?
You are not medically qualified to drive a CMV until you are recertified. For CDL holders, the state may downgrade the license if the medical status is not updated in time. Book the exam well before the expiration date.
Can I drive with sleep apnea?
Sleep apnea is not an automatic disqualification under federal rules. Examiners use their judgment and may ask for testing or proof of treatment, such as CPAP compliance records, before certifying.
