Blood Pressure and DOT Physicals: Certification and Preparation

High blood pressure can affect the outcome and duration of a DOT medical certificate. The medical examiner considers examination readings, treatment, side effects, medical history and other conditions. A single number does not guarantee a passing result.

How blood pressure affects DOT certification

The federal standard addresses high blood pressure that is likely to interfere with safe commercial driving. FMCSA’s 2024 Medical Examiner’s Handbook, section 4.6, provides the following advisory guidance. These certification categories should not be mistaken for general clinical definitions of healthy blood pressure or individual treatment targets.

• Stage 1: Systolic 140–159 and/or diastolic 90–99 mmHg may permit a one-year certificate, subject to the complete examination. Follow-up certification generally requires readings at or below 140/90.
• Stage 2: Systolic 160–179 and/or diastolic 100–109 may permit a one-time three-month certificate to initiate or adjust treatment. It is not automatic. When treatment is well tolerated and pressure is at or below 140/90, a one-year certificate may be appropriate.
• Stage 3: At 180 systolic or 110 diastolic and above, the handbook advises against qualification, even briefly, until pressure is at or below 140/90 and treatment is well tolerated. Subsequent certification may be for six months.

Both numbers matter. The examiner confirms elevated readings and evaluates the complete medical picture. A lower reading does not automatically produce a two-year certificate. Treated hypertension generally calls for at least annual certification review; other medical conditions can shorten the period further. See also FMCSA’s hypertension certification FAQ.

Three practical steps before your appointment

1. Work with your treating clinician

Manage blood pressure throughout the year. Discuss treatment goals, medication effects and any symptoms with the clinician who manages your condition. Do not stop prescribed medicine, take extra doses or make last-minute treatment changes to try to pass a DOT examination.

2. Bring useful records

Bring your current medication list, relevant clinician notes and any blood-pressure log requested by the examiner. Home readings provide context, but the readings taken during the qualification examination are used for the certification decision. Call ahead if you are unsure which records to bring.

3. Plan for follow-up when needed

The examiner may need additional information, a shorter certification interval or further medical evaluation. A temporary certificate is not available in every case. Preparing records helps the review, but it cannot guarantee a certificate or extend an existing certificate’s expiration date.

Common questions

Must my pulse be between 60 and 100 to pass?

There is no universal federal DOT pass/fail pulse range of 60–100 beats per minute. The examiner records pulse rate and rhythm and evaluates abnormal findings, symptoms, medications and cardiovascular conditions under the applicable standards. A number outside that range deserves assessment; it is not by itself the simple automatic-failure rule previously described on this page.

Is a reading below 140/90 the only way to qualify?

No. FMCSA’s advisory guidance permits certain shorter certification periods for elevated readings, as described above. Eligibility depends on the examination, prior certification and treatment history. The examiner makes the decision; neither a favorable number nor a prepared checklist guarantees qualification.
