Understanding Blood Pressure Requirements for DOT Exams
If you’re a commercial driver getting ready for your DOT physical, you might be wondering: “Can high blood pressure disqualify me?” The short answer is: not always—but it depends on your numbers and how well your condition is managed.
At DOT Modesto, we help drivers meet the FMCSA medical standards, including blood pressure guidelines, so you can stay safe and compliant behind the wheel.
Here’s what you need to know.
🩺 Why Blood Pressure Matters in a DOT Physical
High blood pressure (also called hypertension) can increase the risk of:
- Heart attack
- Stroke
- Sudden loss of consciousness
Because of that, the FMCSA has strict blood pressure requirements for commercial drivers. During your DOT exam, we’ll check your systolic (top number) and diastolic (bottom number) readings.
✅ What’s an Acceptable Blood Pressure for a DOT Exam?
| Blood Pressure Level | DOT Certification Period |
|---|---|
| Below 140/90 | 2 years |
| 140–159 / 90–99 | 1 year (Stage 1 hypertension) |
| 160–179 / 100–109 | 3 months initially; then 1 year if improved (Stage 2) |
| 180+ / 110+ | Disqualified until under control (Stage 3) |
❗ Stage 1 Hypertension (Mild)
- You can still be certified for 1 year
- You’ll need to lower your blood pressure before your next exam to get a longer card
❗❗ Stage 2 Hypertension (Moderate)
- You’ll likely be given a 3-month temporary certification
- If your blood pressure improves by your recheck, you can get a 1-year card
❌ Stage 3 Hypertension (Severe)
- You cannot be certified at this level
- You must get your blood pressure under control before reapplying
✅ Tips to Improve Your Blood Pressure Before Your Exam
- Take all medications as prescribed
- Avoid energy drinks, salty foods, and caffeine 24 hours before your exam
- Get a good night’s sleep
- Drink water and relax before your appointment
- Exercise regularly and reduce stress if possible
📝 What If I’m on Blood Pressure Medication?
That’s okay! Drivers can still pass the DOT exam while taking blood pressure meds—as long as the condition is controlled and you’re not experiencing serious side effects (like dizziness or drowsiness).
Just bring:
- A list of your medications
- A note from your provider (if requested by the examiner)
⚠️ What Happens If My Reading Is Borderline?
If your blood pressure is on the edge, we may:
- Recheck it after 10–15 minutes
- Let you rest and try again
- Give you a short-term card while you follow up with your doctor
We’re here to work with you—not against you.
