NRCME Medical Standards and Regulations 4 — Questions and Answers
Question 1: A driver with a history of alcohol use disorder has been in documented remission for 2 years with no relapse. What does FMCSA guidance recommend regarding certification?
- Permanent disqualification regardless of remission duration
- May certify after obtaining a SAP clearance letter
- Medical examiner uses clinical judgment; remission supports certification (Correct answer)
- Certify only with state-issued exemption
Correct answer: Medical examiner uses clinical judgment; remission supports certification
FMCSA guidance allows medical examiners to use clinical judgment; sustained remission is a favorable factor but no specific remission period guarantees certification.
Question 2: Under FMCSA physical qualification standards, which psychiatric condition is listed as disqualifying in 49 CFR 391.41(b)(9)?
- Generalized anxiety disorder controlled with SSRIs
- Any mental disorder likely to interfere with safe driving (Correct answer)
- History of depression treated with psychotherapy
- Attention deficit disorder managed without medication
Correct answer: Any mental disorder likely to interfere with safe driving
49 CFR 391.41(b)(9) disqualifies any mental or functional disorder likely to interfere with safe vehicle operation.
Question 3: A driver presents with a missing left hand but uses a prosthetic device effectively. Under FMCSA regulations, what is required for certification?
- Automatic disqualification for any limb loss
- A Skill Performance Evaluation (SPE) certificate (Correct answer)
- State-level medical waiver only
- No special action needed if the driver performs normally
Correct answer: A Skill Performance Evaluation (SPE) certificate
Drivers with limb loss or impairment who can still operate a CMV safely may receive a Skill Performance Evaluation (SPE) certificate.
Question 4: According to FMCSA medical standards, what is the minimum required field of vision for each eye?
- At least 60 degrees in the horizontal meridian
- At least 70 degrees in the horizontal meridian (Correct answer)
- At least 120 degrees total combined
- At least 80 degrees in any direction
Correct answer: At least 70 degrees in the horizontal meridian
FMCSA requires at least 70 degrees of peripheral vision in the horizontal meridian in each eye.
Question 5: A driver presents with a documented history of myocardial infarction 18 months ago and has since undergone coronary artery bypass grafting with full functional recovery. What should the medical examiner do?
- Permanently disqualify the driver
- Certify for 2 years without restriction
- Evaluate using FMCSA cardiovascular guidelines and consider specialist clearance (Correct answer)
- Issue a 3-month certificate only
Correct answer: Evaluate using FMCSA cardiovascular guidelines and consider specialist clearance
Post-MI drivers require evaluation per FMCSA cardiovascular advisory criteria, often including cardiologist input, before certification decisions are made.
Question 6: Which of the following medications, if taken by a commercial driver, would most likely result in the medical examiner declining to certify the driver?
- Lisinopril for hypertension
- Metoprolol succinate for stable heart rate control
- Methadone for opioid use disorder treatment (Correct answer)
- Atorvastatin for hyperlipidemia
Correct answer: Methadone for opioid use disorder treatment
Methadone use is generally disqualifying for CMV drivers as it is a narcotic that can impair alertness and reaction time.
Question 7: Under FMCSA regulations, which of the following correctly describes the medical examiner's obligation when a driver's condition does not clearly meet or fail the standards?
- Always certify in favor of the driver
- Disqualify until a specialist confirms safety
- Use medical best judgment and may consult advisory criteria (Correct answer)
- Defer to the motor carrier's medical officer
Correct answer: Use medical best judgment and may consult advisory criteria
When conditions fall in a gray area, medical examiners should apply clinical judgment and may consult FMCSA advisory criteria and specialist opinions.
