Cascade Health Clinic is a Certified Medical Examiner (CME) that is listed on the National Registry of Certified Medical Examiners. The law requires that commercial motor vehicle drivers obtain a DOT physical exam every 2 years or sooner if needed. The purpose of the CDL physical exam – also called DOT physical exam – is to ensure that the driver meets the criteria of the physical, mental and emotional needs that it takes to drive long hours and maintain safety. The Federal Motor Carrier Safety Administration (FMCSA) allows only certified medical examiners to do the CDL physical exam.

Schedule Your CDL Physical Exam


What to Expect During Your CDL Physical Exam


All commercial drivers are required to have at least 20/40 acuity in each eye with or without correction. In addition, commercial drivers are required to have at least 70” peripheral in the horizontal meridian, measured in each eye.


Commercial drivers are required to be able to perceive what is known as a “forced whisper” at a distance of 5ft or less, with or without a hearing aid. This CDL physical exam standard equates to an average hearing loss in the better ear of less than 40 dB.

Blood Pressure/Pulse Rate

Our certified medical examiner will check the driver’s blood pressure and pulse to look for high blood pressure and irregular heartbeats.


For all CDL physical exams an urinalysis is required. The test looks for indications of underlying medical conditions and is not a drug test

Physical Examination

The DOT physical exam will cover several different categories:

  • General appearance
  • Eyes (cataracts, glaucoma, macular degeneration, etc.)
  • Ears (scarring of tympanic membrane, perforated ear drums, etc.)
  • Mouth and throat (to look for problems breathing or swallowing)
  • Heart (murmurs, extra sounds, pacemaker, etc.)
  • Lungs and chest, not including breast examination (abnormal breathing, impaired respiratory functions, cyanosis, etc.)
  • Abdomen and Viscera (enlarged liver, viscera, muscle weakness)
  • Vascular (abnormal pulse, carotid, varicose veins)
  • Genito-urinary (hernias)
  • Extremities (limb impaired)
  • Spine, other musculoskeletal (previous surgery, limitation of motion, tenderness, etc.)
  • Neurological (impaired equilibrium, coordination or speech pattern, ataxia, asymmetric deep tendon reflexes)

A DOT physical exam can only be completed by a medical examiner certified by the FMCSA. It is up to the certified medical examiner to determine if a candidate meets all the requirements, and to mark the report to the best of their knowledge and ability.

What to Know About Your CDL Medical Exam

If the medical examiner finds that the person he/she examined is physically qualified to drive a commercial motor vehicle, the medical examiner will complete a Medical Examiner’s Certificate and give the original to the person who was examined. Also, the medical examiner will keep a copy of the Medical Examiner’s Certificate on file for at least 3 years. Furthermore, if a driver wishes the Certificate to be in card form, he/she may: Purchase a separate “medical card” from an industry supplier of motor carrier forms (e.g., State trucking association) before the physical exam and ask the medical examiner to complete and sign it, in addition to the Medical Examination Report form; or Print the Certificate on cardstock paper. It is permissible to reduce the size of the Certificate. For more information please visit FMCSA.
