NRCME DOT Certification Practice Exam – Full 150 Questions with Verified Answers &
Rationale
1. Under 49 CFR §391.41, who is authorized to perform a DOT physical examination?
A. Any licensed physician
B. A physician assistant only
C. A medical examiner listed on the National Registry of Certified Medical Examiners
(NRCME)
D. A nurse practitioner with state approval
Rationale: Only providers certified and listed on the FMCSA National Registry may perform and certify
DOT medical exams. This includes MDs, DOs, PAs, and NPs who have completed NRCME training and
testing.
2. What is the maximum certification period for a commercial driver with stable,
well-controlled type 2 diabetes managed with oral agents only?
A. 1 year
B. 2 years
C. 6 months
D. Not certifiable
Rationale: Per FMCSA guidelines (2026 update), drivers with type 2 diabetes controlled with diet or
oral agents (no insulin) may receive a 2-year certification if A1c ≤ 8% and no complications affecting
driving safety.
3. A driver presents with a history of a single unprovoked seizure 5 years ago and has been
seizure-free since. What is the appropriate certification decision?
, A. Certify for 2 years
B. Certify for 1 year
C. Disqualify until 8 years have passed since the last seizure (4 years off anti-epileptics + 4
years seizure-free)
D. Certify with restrictions
Rationale: FMCSA requires 8 years total: 4 years seizure-free off anti-epileptic drugs (AEDs) plus 4
additional years seizure-free. A single unprovoked seizure still carries risk of recurrence; full 8-year
wait is required.
4. Which vision standard must a commercial driver meet for interstate commerce?
A. 20/40 in one eye, with or without correction
B. 20/40 in each eye and both eyes together, with or without corrective lenses
C. 20/70 in better eye with correction
D. Peripheral vision not required
Rationale: 49 CFR §391.41(b)(2) requires distant visual acuity of at least 20/40 in each eye and in both
eyes together, with or without corrective lenses. Field of vision must be ≥70° in each eye horizontally.
5. Which medication is absolutely disqualifying for a commercial driver in interstate
commerce?
A. Metformin
B. Lisinopril
C. Methadone for opioid use disorder
D. Sertraline
Rationale: Methadone is a Schedule II controlled substance and is disqualifying for interstate drivers,
regardless of stability or prescription. Other opioids (e.g., buprenorphine) may be evaluated
case-by-case under 2026 guidelines, but methadone remains non-certifiable.
6. How soon must a medical examiner submit exam results to the National Registry after
completing a DOT physical?
