Maryland CDL Medical Requirements and Exams

2 min read

To obtain or renew a Commercial Driver’s License (CDL) in Maryland, drivers must meet health criteria established by federal and state regulations.

🚑 Medical Standards for CDL Holders

CDL applicants must pass a medical qualification process based on Federal Motor Carrier Safety Administration (FMCSA) regulations. Requirements include:

  • Physical exam by a certified medical examiner checking vision, hearing, cardiovascular and neurological health.
  • Vision: At least 20/40 acuity in each eye (corrected) and field of vision of 70° laterally.
  • Hearing: Must hear a 5 dB whisper at 5 ft in both ears or meet FMCSA audiometric standards.
  • Blood pressure/Heart rate: Controlled and within safe limits.
  • Other conditions: No insulin-treated diabetes, severe respiratory issues, uncontrolled epilepsy, or substance use disorders.

The Medical Exam Process

  1. Find a certified examiner registered on the FMCSA National Registry.
  2. Complete Form MCSA-5875 (Medical Examiner’s Report) during the appointment.
  3. Receive a Medical Examiner’s Certificate (MEC) valid for up to 24 months—more frequent exams may be required if you have certain health issues.

Submission to MVA

Submit the completed MEC when applying for or renewing your CDL at a Maryland MVA location. Be sure to bring:

  • MD driver’s license or Commercial Learner’s Permit (CLP)
  • CDL application forms and appropriate fees
  • Any supporting medical documentation

Situations Requiring Additional Review

Certain medical conditions may trigger further evaluation:

  • Cardiac issues, such as heart attack or stroke
  • Diabetes managed with insulin
  • Sleep apnea if untreated or severe
  • Seizure disorders not well controlled

In such cases, the medical examiner may impose restrictions on your CDL or require a follow-up exam.
