Quick Answer
The DOT physical is a medical exam required for CMV drivers, performed by an examiner on FMCSA's National Registry. It checks vision, hearing, blood pressure, urine (for kidney indicators, it's not a drug test), and overall fitness to drive. A medical certificate is valid up to 24 months, with shorter cards for conditions like high blood pressure. Since June 2025, exam results flow electronically from the examiner to FMCSA to your state licensing agency.
Key Takeaways
- Only examiners listed on FMCSA's National Registry can perform the exam, verify before booking.
- Standards include 20/40 vision (correction allowed), a forced-whisper hearing test, and blood pressure limits that can shorten your card to 1 year or less.
- The urinalysis screens kidney health markers, it is not a drug test (that's a separate program).
- Under the NRII rule, CDL exam results transmit electronically to your state; verify your record updated, and non-CDL drivers still carry the paper certificate.
What the exam covers
A certified medical examiner reviews your health history and checks: vision (at least 20/40 in each eye, glasses or contacts allowed, plus 70 degrees of peripheral field per eye), hearing (perceive a forced whisper at 5 feet, hearing aid permitted), blood pressure and pulse, a urinalysis screening for protein, blood, and sugar as kidney-health indicators, and a physical exam of heart, lungs, spine, and neurological function.
Bring your glasses or hearing aids, a list of medications, and records for any managed condition (recent readings for blood pressure, A1C results for diabetes), showing control is how you get the longest card your condition allows.
How long the medical card lasts
The maximum certificate is 24 months. Examiners issue shorter cards to monitor conditions: high blood pressure commonly earns a 1-year card (or 3 months to demonstrate control), and insulin-treated diabetes is certifiable but on an annual cycle with treating-clinician documentation.
Mark the expiry, driving on a lapsed card is a driver-qualification violation that feeds the carrier's CSA record.
What changed: electronic filing (NRII)
Since June 23, 2025, medical examiners must transmit results electronically to FMCSA's National Registry by the next day, and FMCSA forwards them to your state licensing agency, for CDL holders, no more walking a paper card into the DMV.
The transition had growing pains: FMCSA ran temporary waivers letting drivers rely on the paper certificate while states caught up.
Practical advice for 2026: keep the paper certificate the examiner gives you until you've confirmed your state record shows the new expiration date (allow several processing days). Non-CDL CMV drivers are unchanged, they still receive and must carry the paper certificate.
What can disqualify you
Hard stops are fewer than drivers fear. Uncorrectable vision or hearing below standard, unmanaged epilepsy, and certain cardiac conditions are disqualifying, though several have federal exemption or waiver paths. The most common fixable failure is blood pressure walking in high: hydrate, skip the energy drinks that morning, and treat the reading like the vital sign it is.
Where the drug test fits
The DOT physical's urine test is not a drug screen. Drug and alcohol testing lives in a separate program, pre-employment, random, and post-accident, tracked through the FMCSA Clearinghouse.

FAQ
What is a DOT medical card?
A DOT medical card is the Medical Examiner's Certificate (Form MCSA-5876) that a certified examiner on FMCSA's National Registry gives you after you pass the DOT physical. It shows you are physically qualified to drive a commercial motor vehicle under 49 CFR 391.41, and it is valid for up to 24 months.
Who must have a DOT medical exam?
Anyone who drives a commercial motor vehicle in interstate commerce must be examined and certified, whether or not they hold a CDL (49 CFR 391.45). That includes drivers of trucks or truck-and-trailer combinations rated 10,001 lbs or more, such as many hotshot rigs. You must be re-examined at least every 24 months, or sooner if the examiner gave you a shorter certificate. Drivers of covered farm vehicles are exempt (49 CFR 391.2), and intrastate-only drivers follow their state's rules.
How long is a DOT medical card good for?
Up to 24 months, but examiners issue 1-year, 6-month, or 3-month cards to monitor conditions like high blood pressure or insulin-treated diabetes.
Does a DOT physical include a drug test?
No. The urinalysis in a DOT physical checks for protein, blood and sugar as signs of kidney problems or diabetes. DOT drug and alcohol testing is a separate program under 49 CFR part 382, with its own pre-employment and random tests and Clearinghouse reporting.
Do I still carry a paper medical card?
CDL holders: results now transmit electronically to your state, but keep the paper certificate until you confirm your state record updated. Non-CDL CMV drivers still receive and carry the paper certificate.
