Great question, Before taking the FMCSA/NRCME DOT medical examiner certification
exam, it's crucial to be familiar with the core federal regulations that guide your responsibilities
as a certified medical examiner.
Here’s a high-yield breakdown of the key DOT regulations and concepts you should know
before taking the exam:
🧠 Must-Know FMCSA Regulations (49 CFR – Code of Federal Regulations)
✅ 1. 49 CFR § 391.41 – Physical Qualifications for Drivers
This is THE most important section. It outlines the 13 mandatory driver qualification
standards. Drivers must:
Have distant visual acuity of at least 20/40 in each eye (corrected or uncorrected).
Be able to recognize red, green, and amber colors.
Hear a forced whisper at 5 feet, with or without hearing aid.
BP under 140/90 for 2-year card. Elevated BP = time-limited cert.
