DOT Physical Blood Pressure Requirements: Limits, Chart & How to Pass
This article is for general information only and is not medical advice. If you have a diagnosed blood pressure condition, talk to your doctor before your DOT physical.
What Blood Pressure Do You Need to Pass a DOT Physical?
The Short Answer
FMCSA hypertension guidance affects how long your DOT medical card lasts: up to 2 years under 140/90, usually up to 1 year at Stage 1, a one-time certificate of up to 3 months at Stage 2, and generally no certification at Stage 3 (180/110 or higher) until your blood pressure is controlled.
- Under 140/90: Up to a 2-year medical certificate; drivers diagnosed with hypertension and receiving treatment generally require at least annual recertification, even when their BP is below 140/90
- 140–159/90–99 (Stage 1): Typically a 1-year certificate
- 160–179/100–109 (Stage 2): May receive a one-time certificate of up to 3 months to lower BP to 140/90 or less; if controlled and treatment is well tolerated, may then be certified for 1 year
- 180/110+ (Stage 3): Generally not medically qualified until blood pressure is reduced to 140/90 or less and treatment is well tolerated; once controlled, the driver may be certified for 6 months and every 6 months thereafter if BP remains at or below 140/90

Important: These certification periods summarize FMCSA hypertension guidance. Your actual certification period can also depend on your treatment history, medication tolerance, previous blood pressure readings, and overall medical qualification.
What Blood Pressure Is Too High for a DOT Physical?
Under 49 CFR 391.41(b)(6), a commercial driver must have no current clinical diagnosis of high blood pressure likely to interfere with safe operation of a commercial motor vehicle. The numerical stages above are medical advisory guidance FMCSA uses in applying that standard — they aren't a rigid pass/fail line on their own, which is why an examiner's judgment and your treatment history both factor into the outcome.
For a first-time elevated blood pressure finding, Stage 3 — 180/110 or higher — is the range in which FMCSA guidance says the driver should not be medically qualified, even for a short period, until blood pressure is reduced to 140/90 or less and treatment is well tolerated. Drivers with previously diagnosed or treated hypertension may also face certification restrictions if their blood pressure remains above the required level at follow-up.
DOT Blood Pressure Examples: Will You Pass?
| Reading | Likely DOT Outcome |
|---|---|
| 135/85 | Potentially up to a 2-year certificate |
| 140/90 | Stage 1 range |
| 150/90 | Stage 1 range; generally up to 1 year |
| 155/95 | Stage 1 range; generally up to 1 year |
| 160/100 | Stage 2 range; possible one-time 3-month certificate |
| 170/105 | Stage 2 range; possible one-time 3-month certificate |
| 180/110 | Stage 3 range; generally not certified until controlled |
| 190/110 | Stage 3 range; generally not certified until controlled |
Why DOT Blood Pressure Standards Are Different From Your Doctor's Blood Pressure Guidelines
Two Different Standards
Your regular doctor may flag anything at or above 130/80 as "high blood pressure" — that's the American Heart Association's general clinical definition. That is not the same as FMCSA's hypertension staging used for medical certification, which begins at 140/90.
This distinction matters: you can have a reading your family doctor calls "elevated" or "Stage 1" by AHA standards and still pass your DOT physical with a full 1-year or even 2-year certification. A lot of driver confusion online comes from mixing up these two different standards, so if you've seen a "high" flag in a health app or from your regular doctor, that doesn't necessarily mean you're at risk of failing your DOT physical.
First DOT Physical vs. DOT Recertification With High Blood Pressure
What happens with an elevated reading can depend on more than the number itself, including:
- Whether this is the first time your blood pressure has come up elevated
- Whether hypertension has already been formally diagnosed
- Whether you're already taking medication for it
- Your previous certification period and history
- Whether you were previously in the Stage 3 range
- How well you tolerate your current medication
- Other cardiovascular conditions on your record
The Medical Examiner's Handbook directs examiners to consider your hypertension history and treatment status, not just the single reading taken that day — which is part of why two drivers with the same number on a given visit can walk away with different certification periods.
Can You Take Blood Pressure Medication and Pass?
Yes. Drivers can generally be medically certified while using prescribed blood pressure medication, provided their hypertension is adequately controlled and the medication doesn't produce side effects that interfere with safely operating a commercial motor vehicle.
FMCSA guidance notes that antihypertensive drugs can sometimes cause side effects like drowsiness or fainting, and examiners are expected to factor medication tolerance into their decision — not just whether your numbers are controlled, but how you're doing on the medication itself.
Does taking BP medication automatically limit you to a 1-year certificate? Not automatically, but a driver diagnosed with hypertension and receiving treatment should generally have at least annual certification, even if a given reading comes in under 140/90.
How DOT Blood Pressure Testing Works
A certified medical examiner takes your blood pressure as part of the standard exam. A few things worth knowing:
- The exam reflects the reading(s) taken that day, not an average over time the way your regular doctor might track it.
- The medical examiner considers your blood pressure readings together with your medical history, treatment status, medication tolerance, and FMCSA hypertension guidance when making the certification decision — it's an overall medical assessment, not a lookup on a chart.
White Coat Syndrome and Retesting
If your initial blood pressure reads above 139/89, FMCSA guidance says it should be confirmed with a second measurement taken later during the examination. Stress, rushing, physical exertion, or "white coat" anxiety can temporarily affect a first reading, so this second measurement helps the examiner get a more accurate picture before making a certification decision.
How to Get an Accurate Blood Pressure Reading at Your DOT Physical
The goal here is an accurate reading, not a way to temporarily mask a real chronic condition — an artificially low reading on exam day doesn't change your actual health risk, it just delays you finding out about it somewhere less convenient than a clinic.
What helps get an accurate reading:
- Take your prescribed medication on your normal schedule — don't skip it
- Don't take extra doses beyond what's prescribed, hoping to lower your number further
- Arrive early enough to sit quietly for a few minutes before the exam
- Avoid rushing directly from driving or physical exertion into the exam room
- Bring a current medication list and be ready to discuss your treatment history
- Tell the examiner if you've been tracking elevated readings at home
- Don't intentionally dehydrate yourself or use unprescribed medications or supplements to try to force the number down
If you have a diagnosed, chronic BP condition, talk to your doctor before your exam — not the morning of. Ongoing management is what actually moves your certification stage long-term.
What to Bring to Your DOT Physical If You Have High Blood Pressure
- A current medication list
- Your prescribing doctor's contact information
- Recent blood pressure readings, if your doctor has asked you to track them
- Information about any recent medication changes
- Glasses or hearing aids, if applicable
- Any medical records the examiner has specifically requested
This isn't a federally required checklist, but having this information available can help the examiner understand your treatment history and may help avoid delays or requests for additional documentation.
Example: Driver Shows Up With 165/102
Real-World Example
A CDL driver arrives for his DOT recertification and records 165/102. That falls within FMCSA's Stage 2 hypertension range. Rather than automatically receiving a full annual certificate, the driver may be issued a one-time certificate of up to three months so the blood pressure can be treated or adjusted. If the driver's blood pressure reaches 140/90 or less at the follow-up and treatment is well tolerated, he may then qualify for a longer certification period.
Does High Blood Pressure Make You Lose Your CDL?
Usually, the issue is your DOT medical certification, not cancellation of the CDL itself. Interstate CDL drivers required to maintain medical certification must keep their medical status current with their State Driver Licensing Agency. If a driver loses medical qualification, they generally cannot legally operate a commercial motor vehicle requiring that certification until they become medically qualified again — but the CDL and the medical certificate are two separate things.
What Happens If You Don't Pass Because of Blood Pressure?
A first-time Stage 1 reading may allow certification for up to 1 year.
You may receive a one-time certificate of up to 3 months to initiate or adjust treatment.
You generally should not be medically qualified until your blood pressure is reduced to 140/90 or less and treatment is well tolerated.
Frequently Asked Questions
What BP will fail a DOT physical?
From a blood pressure standpoint, a Stage 3 reading of 180/110 or higher generally means the driver should not be medically qualified at that examination until BP is reduced to 140/90 or less and treatment is well tolerated. Drivers being recertified for previously elevated blood pressure may have different requirements depending on their prior certification and treatment history. Once controlled, the driver may be certified for 6 months at a time.
Can I pass a DOT physical with 150/90 blood pressure?
From a blood pressure standpoint, yes — a first-time reading of 150/90 falls in FMCSA's Stage 1 range and may result in certification for up to 1 year, assuming you otherwise meet DOT medical requirements.
Can I pass a DOT physical with 160/100?
That's in the Stage 2 range. You may receive a one-time 3-month certificate to bring your blood pressure down, then a longer certification once it's controlled.
What happens if my blood pressure is high during a DOT physical?
Depending on the stage and your previous hypertension history, you may receive a shorter certification period rather than an outright denial. A first-time Stage 3 reading of 180/110 or higher generally means no certification until blood pressure is controlled. Drivers being recertified for previously elevated blood pressure may have additional follow-up requirements.
Can the DOT examiner take my blood pressure twice?
Yes — in fact, FMCSA guidance says readings greater than 139/89 should be confirmed with a second measurement taken later during the examination.
Can I get a 3-month DOT medical card for blood pressure?
A driver with Stage 2 hypertension (160–179/100–109) may receive a one-time certificate of up to 3 months to initiate or adjust treatment and reduce BP to 140/90 or less.
Can I drive a truck while taking blood pressure medication?
Yes, generally, as long as your hypertension is controlled and the medication doesn't cause side effects like drowsiness that would interfere with safe driving.
How long is a DOT medical card with hypertension?
It depends on your stage and treatment history: up to 2 years if well below 140/90 with no hypertension diagnosis, 1 year for Stage 1, a one-time 3-month certificate for Stage 2, and 6-month intervals once a previously Stage 3 reading is controlled.
Is 140/90 passing for a DOT physical?
140/90 falls at the edge of the Stage 1 range and typically results in a 1-year certificate rather than disqualification.
Is 130/80 good enough for a DOT physical?
From a DOT blood pressure standpoint, yes — 130/80 is below FMCSA's Stage 1 threshold. However, the American Heart Association classifies 130–139 systolic or 80–89 diastolic as Stage 1 hypertension under its own clinical guidelines, not merely "elevated."
Does white coat syndrome affect a DOT physical?
It can affect a single reading. FMCSA guidance says a reading greater than 139/89 should be confirmed with a second measurement taken later during the examination, which helps account for a temporarily elevated first reading.
Can a DOT examiner fail me for high blood pressure?
Yes. Stage 3 hypertension — 180/110 or higher — generally means no certification until the blood pressure is controlled. Drivers with previously diagnosed or treated hypertension can also be denied certification if they don't meet the applicable follow-up requirements.
Can I retake a DOT physical after failing for blood pressure?
Yes. Once your blood pressure is reduced to 140/90 or less and your treatment is well tolerated, you can be re-examined and may be certified, assuming you otherwise meet DOT medical requirements.
How soon can I retake my DOT physical?
There is no fixed federal waiting period solely for hypertension. Once your blood pressure is controlled, you can undergo another examination — the examiner will consider the readings taken during that exam along with your medical and treatment history.
Does high blood pressure affect my CDL or just my medical card?
It affects your medical certificate, not your CDL directly. However, you generally can't legally operate a CMV requiring that certification without a current medical card.
