Introduction to DOT Physicals

The Department of Transportation (DOT) requires commercial vehicle drivers to undergo regular physical examinations to ensure they are fit to operate on public roads. These physicals help maintain safety standards and protect both the driver and the public. In this comprehensive guide, we will cover the DOT exam requirements, what to expect during the examination, and how to prepare for a successful assessment.

What Are DOT Exam Requirements?

The DOT exam requirements, established by the Federal Motor Carrier Safety Administration (FMCSA), are designed to ensure that commercial drivers are in good physical and mental health. The examination evaluates various aspects of a driver’s health, including vision, hearing, blood pressure, and the presence of any medical conditions that may affect their ability to safely operate a commercial vehicle.

Vision Requirements

Commercial drivers must meet the following vision requirements:

  • Distant visual acuity of at least 20/40 in each eye, with or without corrective lenses
  • Field of vision of at least 70 degrees in the horizontal meridian in each eye
  • The ability to recognize the colors of traffic signals and devices (red, green, and amber)

Hearing Requirements

To meet DOT hearing requirements, drivers must:

  • Perceive a forced whispered voice in the better ear at not less than 5 feet, with or without the use of a hearing aid
  • Alternatively, pass an audiometric test with an average hearing loss of no more than 40 dB in the better ear at 500 Hz, 1000 Hz, and 2000 Hz

Blood Pressure and Pulse Requirements

The DOT physical exam assesses blood pressure and pulse for abnormalities, including high blood pressure (hypertension) and irregular heartbeats (arrhythmias). The following are the general blood pressure guidelines:

  • Normal: Less than 140/90
  • Stage 1 Hypertension: 140-159/90-99
  • Stage 2 Hypertension: 160-179/100-109
  • Stage 3 Hypertension: 180 or higher/110 or higher

Drivers with blood pressure in the Stage 1 range may receive a one-year medical certification, while those in the Stage 2 range may be granted a temporary three-month certification. Stage 3 hypertension may disqualify a driver until their blood pressure is controlled.

Medical Conditions and Medications

The DOT physical also assesses drivers for various medical conditions, including diabetes, respiratory issues, cardiovascular disorders, and neurological conditions. The examining healthcare professional will review a driver’s medical history and current medications to determine if they are fit to drive.


Drivers with diabetes must meet specific requirements, including:

  • Maintaining a stable blood sugar level through proper diet, exercise, and medication
  • Providing proof of proper blood sugar monitoring
  • No history of severe hypoglycemic episodes or diabetic complications that may impair driving ability

Respiratory Conditions

Drivers with respiratory conditions, such as sleep apnea, asthma, or chronic obstructive pulmonary disease (COPD), must demonstrate that their condition is well-managed and does not negatively impact their ability to drive safely.

Cardiovascular Disorders

Drivers with a history of cardiovascular disorders, including heart attacks or heart surgeries, must provide documentation from their cardiologist indicating that they are stable and cleared for commercial driving.

Neurological Conditions

Neurological conditions, such as epilepsy or a history of seizures, may disqualify a driver from receiving a DOT medical certification. However, exceptions may be granted on a case-by-case basis with proper documentation and medical clearance.

Preparing for Your DOT Physical Examination

To ensure a smooth DOT physical examination, follow these steps:

    1. Gather all necessary documentation, including medical records and a list of current medications.
    2.  Ensure that your prescription eyewear or hearing aids are up to date and functioning properly.
    3. Refrain from consuming caffeine or nicotine for at least 30 minutes before the examination, as these substances can temporarily increase blood pressure.
    4. Get a good night’s sleep before the exam to ensure you are well-rested and alert.
    5. If you have a chronic medical condition, consult with your primary care physician or specialist to ensure that your condition is well-managed and stable.

What to Expect During the DOT Physical Examination

The DOT physical examination typically includes the following components:

Medical History Review

The healthcare professional will review your medical history, including any chronic medical conditions, prior surgeries, and current medications. Be prepared to provide detailed information about your health and any past or present medical concerns.

Physical Examination

The physical examination will assess your general health and fitness to operate a commercial vehicle. This includes an evaluation of your:

      • Eyes (visual acuity, color vision, and peripheral vision)
      • Ears (hearing ability)
      • Mouth and throat (for breathing and swallowing difficulties)
      • Heart (pulse, blood pressure, and any abnormalities)
      • Lungs and chest (respiratory function)
      • Abdomen and organs (for masses, hernias, or tenderness)
      • Vascular system (for proper circulation)
      • Limbs (for proper function, strength, and range of motion)
      • Spine and musculoskeletal system (for proper posture and flexibility)
      • Neurological system (reflexes, balance, and coordination)


A urinalysis is conducted to screen for indicators of underlying medical conditions, such as diabetes or kidney issues. The test checks for glucose, protein, and blood in the urine.

DOT Physical Certification and Recertification

Once the DOT physical examination is complete, the healthcare professional will determine if you meet the medical standards for commercial driving. If you pass the exam, you will receive a DOT medical certificate, which is valid for up to 24 months. However, drivers with certain medical conditions, such as hypertension or diabetes, may be required to undergo more frequent examinations.

To maintain your DOT medical certification, it’s essential to stay on top of your health and manage any chronic medical conditions effectively. Keep a close eye on your blood pressure, blood sugar, and overall fitness to ensure you remain in compliance with DOT regulations.


DOT physical requirements are designed to ensure that commercial drivers maintain a high level of physical and mental health. By understanding these requirements and properly preparing for the DOT physical examination, you can help ensure the safety of both yourself and others on the road.
