What Commercial Drivers Need to Know
February is American Heart Month, making it the perfect time to focus on heart health—especially for commercial drivers required to pass a DOT physical. Heart conditions and high blood pressure are major concerns in the transportation industry, and understanding how they impact DOT medical certification is essential for drivers and employers alike.
Understanding the DOT Physical
A Department of Transportation (DOT) physical is a mandatory medical exam for commercial drivers to ensure they are physically fit to operate a vehicle safely. Conducted by a certified medical examiner, the exam evaluates key health factors, including cardiovascular health, blood pressure, diabetes, vision, hearing, and overall physical condition.
Among these, heart health is a major component, as conditions like high blood pressure or heart disease can affect a driver’s ability to safely operate a commercial motor vehicle (CMV).
Heart Health and DOT Physical Requirements
The Federal Motor Carrier Safety Administration (FMCSA) has established medical standards related to cardiovascular conditions in the Physical Qualifications for Drivers Regulation 49 CFR §391.41(b)(4). Additionally, the FMCSA has provided guidelines for Medical Examiners to use when evaluating heart conditions to assess a driver’s fitness to operate a commercial motor vehicle. Key considerations include:
- Hypertension (High Blood Pressure): Drivers with blood pressure below 140/90 mmHg can be certified for two years. Depending on severity, those with elevated blood pressure may require monitoring, medication, or temporary disqualification.
- History of Heart Attack or Stroke: Drivers with a history of myocardial infarction (heart attack) or stroke must provide documentation from a cardiologist confirming their ability to drive safely.
- Pacemakers or Implantable Cardioverter Defibrillators (ICDs): Drivers with pacemakers may be medically certified after providing documentation confirming pacemaker functionality and effectiveness along with clearance from Cardiologist attesting they are safe to drive. Those with ICDs, must apply for and obtain an Exemption directly from the FMCSA to be medically qualified to drive a CMV.
- Heart Surgery (Bypass or Stents): In addition to presenting clearance from their treating Cardiologist, there typically would be a post-surgical recovery (waiting) period before a Medical Examiner would determine the person is medically qualified to return to commercial driving.
Managing Blood Pressure for DOT Compliance
Blood pressure levels play a significant role in DOT certification. Here’s a breakdown of the FMCSA guidelines:
Blood Pressure (BP) Reading: | Certification Period: |
Less than 140/90 mmHg | 2 years |
140/90 – 159/99 mmHg | 1-year certification |
160/100 – 179/109 mmHg | 3-month temporary certification; must reduce BP |
180/110 mmHg or higher | Disqualified until BP is controlled |
Drivers with high blood pressure should work with their healthcare provider to manage it through medication, diet, exercise, and lifestyle changes.

8 Factors that Impact Your Heart Health
- Cholesterol: High LDL cholesterol can block arteries and increase the risk of heart attack and stroke. A low-fat diet can help reduce your LDL cholesterol, while regular exercise can boost your HDL cholesterol, known as good cholesterol.
- Resting Heart Rate: A resting heart rate of 60 to 100 beats per minute is considered normal for most individuals. Regular exercise can lower your heart rate and decrease your risk of heart-related issues.
- Cardiorespiratory Fitness: Engaging in aerobic exercise can strengthen your heart and lower the risk of developing dementia, Alzheimer’s disease, diabetes, and certain types of cancers. Even a brisk 10–15-minute walk can be beneficial.
- Blood Pressure: High blood pressure is a significant risk factor for heart attack, stroke, and heart failure. Regularly monitoring your blood pressure helps you understand your numbers.
- Blood Glucose Level: Excess sugar in the blood, often due to insufficient insulin production or poor insulin usage, can lead to Type 2 diabetes. A low-fat diet that limits sweets, added sugars, and processed meats can help maintain healthy blood sugar levels.
- Waist Circumference: A larger waist size is linked to a higher risk of high blood pressure and elevated cholesterol levels. Men should aim for a waist circumference of less than 40 inches, while women should aim for less than 35 inches.
- Heart Rhythm: Common symptoms of atrial fibrillation include weakness, shortness of breath, dizziness, heart palpitations, or an irregular heartbeat. If you experience these symptoms, consult your doctor immediately for treatment.
- Family History: If your parents, grandparents, or siblings have experienced a stroke, heart attack, or any form of heart disease, share this information with your doctor, as it may indicate an increased risk for you.
Heart Health Tips for Commercial Drivers
Maintaining heart health is crucial for long-term success in the transportation industry. Here are some heart-healthy habits to adopt:
- Monitor Blood Pressure Regularly: Keep track of your numbers and follow your doctor’s recommendations.
- Eat a Heart-Healthy Diet: Focus on lean proteins, whole grains, fruits, vegetables, and limit sodium intake.
- Stay Active: Incorporate walking, stretching, or simple exercises into your routine, even on the road.
- Manage Stress: Long hours and tight schedules can increase stress—practice deep breathing, meditation, or relaxation techniques.
- Stay Hydrated & Limit Caffeine: Drinking water and reducing excessive caffeine consumption can help regulate blood pressure.
