NRCME Medical Standards and Regulations 5 — Questions and Answers
Question 1: A driver has a diagnosis of obstructive sleep apnea but refuses CPAP therapy. What is the appropriate FMCSA certification action?
- Certify for 1 year and re-evaluate
- Issue a temporary 3-month certificate
- Do not certify until effective treatment is documented (Correct answer)
- Certify only for daytime driving hours
Correct answer: Do not certify until effective treatment is documented
Untreated obstructive sleep apnea poses a risk of sudden incapacitation; certification should not be issued until adequate treatment compliance is demonstrated.
Question 2: Under FMCSA regulations, color blindness in a commercial driver is:
- An automatic disqualifying condition
- Acceptable as long as the driver can distinguish traffic signals (Correct answer)
- Disqualifying only for hazardous materials transport
- Allowed with a federal color vision exemption
Correct answer: Acceptable as long as the driver can distinguish traffic signals
Color blindness is not an automatic disqualifier; the driver must be able to distinguish colors of traffic signals and devices showing red, green, and amber.
Question 3: When must a medical examiner complete a new physical examination for a commercial driver who previously held a 2-year certificate and develops a new significant medical condition?
- Only at the next regular 2-year renewal
- Within 6 months of the new diagnosis
- Immediately upon learning of the disqualifying condition (Correct answer)
- Within 30 days of the condition being reported
Correct answer: Immediately upon learning of the disqualifying condition
If a driver develops a condition that may affect qualification, re-examination should occur promptly rather than waiting for the certificate to expire.
Question 4: Under FMCSA physical qualification standards, which of the following correctly describes the standard for respiratory conditions?
- FEV1 must be greater than 80% of predicted value
- No driver with asthma may be certified
- No established specific spirometry cutoff; examiner uses clinical judgment (Correct answer)
- Oxygen saturation must exceed 95% at rest
Correct answer: No established specific spirometry cutoff; examiner uses clinical judgment
FMCSA does not specify exact spirometry values; the examiner determines if the respiratory condition is likely to interfere with safe driving.
Question 5: A driver discloses current use of a Schedule II controlled substance prescribed by their physician. How should the NRCME-certified examiner respond?
- Certify if the driver has a valid prescription
- Certify only for intrastate operations
- Do not certify; Schedule II controlled substances are disqualifying (Correct answer)
- Issue a 6-month certificate pending DEA review
Correct answer: Do not certify; Schedule II controlled substances are disqualifying
Use of Schedule II controlled substances is disqualifying regardless of whether the driver holds a valid prescription, per 49 CFR 391.41(b)(12).
Question 6: Which of the following best describes the purpose of the Long-Term Driver Program (LTDP) exemption under FMCSA?
- Allows drivers over age 70 to operate without annual recertification
- Permits experienced drivers with certain conditions to continue driving under safety monitoring (Correct answer)
- Grants permanent certification to drivers with 20+ years of safe driving
- Exempts veteran drivers from the vision standard
Correct answer: Permits experienced drivers with certain conditions to continue driving under safety monitoring
The LTDP and similar exemption programs allow drivers who would otherwise be disqualified to continue driving under enhanced safety monitoring conditions.
Question 7: If a medical examiner discovers that a driver falsified information on the Medical Examination Report Form (MCSA-5875), what is the appropriate action?
- Issue a certificate with a noted discrepancy
- Disqualify the driver and report the falsification to FMCSA (Correct answer)
- Refer the driver to their primary care physician
- Issue a 90-day temporary certificate pending verification
Correct answer: Disqualify the driver and report the falsification to FMCSA
Falsification of medical examination information is a serious violation; the examiner should not certify and should report the falsification per FMCSA requirements.
