High Blood Pressure and Your DOT Physical: What Drivers Need to Know

Hypertension is the #1 reason drivers leave a DOT physical without a 2-year certificate. Here is how the rules work and what you can do.

Why Blood Pressure Matters So Much

Hypertension is the single most common finding that affects DOT certification. It can cause sudden incapacitation — stroke, cardiac event — while a driver is operating a commercial vehicle. For that reason, FMCSA has established specific blood pressure thresholds that determine how long a certification is valid.

The Blood Pressure Tiers

Stage Systolic Diastolic Certification
Normal / Stage 1 < 140 < 90 2 years (standard)
Stage 1 Hypertension 140–159 90–99 1 year (annual recertification)
Stage 2 Hypertension 160–179 100–109 3-month temporary certificate
Stage 3 Hypertension 180+ 110+ Disqualified — cannot certify

A driver with Stage 3 hypertension at the time of the exam cannot be certified until their blood pressure is controlled to at least Stage 2 or below.

What If I'm on Blood Pressure Medication?

Being on antihypertensive medication does not disqualify you. In fact, well-controlled hypertension (maintained below 140/90 with medication) typically earns a standard 2-year certification. The examiner will want to know:

  • What medication you take and the dosage
  • Whether the medication causes side effects that could affect driving (dizziness, fatigue)
  • Whether you take it consistently

Bring your medication bottles and any treating physician's notes to your exam.

Tips for the Day of Your Exam

  • Take your medications as prescribed — do not skip them.
  • Avoid caffeine for at least an hour before the exam.
  • Get a good night's sleep. Sleep deprivation temporarily raises blood pressure.
  • Arrive early and sit quietly for 5–10 minutes before the exam begins.
  • Avoid intense exercise the morning of the exam.

If you are anxious about "white coat hypertension" (BP spikes in clinical settings), let your examiner know. In some cases, a brief rest period and a second reading is appropriate.

The 3-Month Temporary Certificate

If you leave with a 3-month temporary certificate due to Stage 2 hypertension, use that time to work with your physician to get your BP under control. Return for re-examination within the 3-month window with documentation that your blood pressure is now below 160/100. If controlled, you can receive a 1-year certificate. Fail to return before the temporary expires and your medical certificate lapses — along with your CDL medical qualification.

Schedule Your DOT Physical

Doctors Place offers same-week appointments for DOT physicals in Hackensack, NJ. Employers can schedule for drivers directly through the portal. If you are concerned about blood pressure, consider having it checked at a pharmacy a few days before your exam to establish a baseline.

Frequently Asked Questions

What blood pressure will fail a DOT physical?+
Stage 3 hypertension — systolic 180 or higher, or diastolic 110 or higher — will result in disqualification. Stage 2 (160–179/100–109) results in a 3-month temporary certificate. Stage 1 (140–159/90–99) results in a 1-year certificate instead of the standard 2-year.
Can I pass a DOT physical if I take blood pressure medication?+
Yes, as long as your blood pressure is well-controlled (below 140/90) with medication and the medication does not cause side effects that impair safe driving. Bring your medication bottles to your exam.
What is a 3-month DOT temporary certificate?+
A 3-month temporary certificate is issued when a driver has Stage 2 hypertension (160–179/100–109) at the time of the exam. The driver must return within 3 months with blood pressure controlled below 160/100 to receive a longer certificate. If they do not return before it expires, their CDL medical certificate lapses.
What should I do if I have white coat hypertension at my DOT physical?+
Tell your examiner. In some cases a rest period and second reading is appropriate. You can also request to have your blood pressure checked at a pharmacy a few days before your exam to establish a baseline and bring that documentation with you.
How soon can I get re-examined after failing for blood pressure?+
There is no mandatory waiting period. Once you have your blood pressure controlled below the disqualifying threshold (under 180/110 to be examined at all), you can schedule a new DOT physical. Doctors Place offers same-week appointments.
