NRCME (DOT) EXAMINER TEST & APPROVED ANSWERS 2026/2027
According to FMCSA regulations, which of the following must the medical
examiner evaluate when examining a driver's eyes?
A. Pupil reactivity
B. Iris symmetry
C. Conjunctival injection
D. Corneal thickness - Correct Response:
A. Pupil reactivity
Incorrect Responses:
B. Iris symmetry
This is incorrect because determining iris symmetry is not required by
FMCSA.
C. Conjunctival injection
This is incorrect because most causes of conjunctival injection would not be
disqualifying. Causes that are suspicious for a disqualifying condition need
additional evaluation. While this abnormal finding should be explained, with
determination of possible effects on safe driving before making a
certification decision, it is not a condition that is specified in FMCSA
regulations.
D. Corneal thickness
This is incorrect because it is not measured in an office examination except
by an eye specialist.
