NRCME Medical Standards and Regulations 5

Question 1

A driver has a diagnosis of obstructive sleep apnea but refuses CPAP therapy. What is the appropriate FMCSA certification action?

Accepted Answer

Do not certify until effective treatment is documented

Answer

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:

Accepted Answer

Acceptable as long as the driver can distinguish traffic signals

Answer

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?

Accepted Answer

Immediately upon learning of the disqualifying condition

Answer

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?

Accepted Answer

No established specific spirometry cutoff; examiner uses clinical judgment

Answer

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?

Accepted Answer

Do not certify; Schedule II controlled substances are disqualifying

Answer

Use of Schedule II controlled substances is disqualifying regardless of whether the driver holds a valid prescription, per 49 CFR 391.41(b)(12).
