,1. A commercial driver with a history of type 2 diabetes is currently on metformin
1000 mg twice daily and reports stable glucose control. Hemoglobin A1c is 7.2%.
According to FMCSA standards, which of the following is the most appropriate
certification decision?
A. Certify for 1 year; require quarterly A1c monitoring.
B. Certify for 3 months; require submission of a 3-month glucose log showing no severe
hypoglycemia.
C. Certify for 2 years with no additional monitoring.
D. Deny certification due to A1c exceeding 7.0%.
Answer: B. Certify for 3 months; require submission of a 3-month glucose log
showing no severe hypoglycemia.
FMCSA requires drivers with diabetes using insulin or oral hypoglycemics to have
stable control and no severe hypoglycemia events. An A1c of 7.2% is acceptable, but the
driver must provide a 3-month glucose log. Certification is typically for 3 months
initially. Option A is too long; C ignores monitoring; D is incorrect because A1c up to
8% may be acceptable with good control.
2. Which of the following best describes the FMCSA's definition of 'disqualifying'
hypertension for a commercial driver?
A. Systolic blood pressure consistently 140 mmHg or diastolic 90 mmHg.
B. Systolic blood pressure 160 mmHg or diastolic 100 mmHg on three separate readings.
C. Systolic blood pressure 180 mmHg or diastolic 110 mmHg at a single examination.
D. Any hypertension requiring more than two antihypertensive medications.
Answer: B. Systolic blood pressure 160 mmHg or diastolic 100 mmHg on three
separate readings.
FMCSA considers hypertension disqualifying if systolic 160 or diastolic 100 on three
separate occasions (or if the driver is already on medication). Option A is the threshold
for diagnosis, not disqualification. Option C is a hypertensive emergency requiring
immediate referral, but not the definition of disqualifying hypertension. Option D is not
a criterion.

,3. A driver has a history of a seizure disorder but has been seizure-free for 8 years
on a stable dose of levetiracetam. According to FMCSA guidelines, what is the
minimum seizure-free period required off anti-epileptic medication before
certification can be considered?
A. 5 years.
B. 10 years.
C. The driver must remain on medication indefinitely; no certification is possible.
D. 1 year.
Answer: B. 10 years.
FMCSA requires a 10-year seizure-free period off anti-epileptic medication (or with
medication if the driver has been seizure-free for 5 years and has a favorable
neurological evaluation). Option A is for drivers on medication. Option C is incorrect
because certification is possible. Option D is too short.
4. A driver presents with a visual acuity of 20/40 in the right eye and 20/100 in the
left eye, with best correction. According to FMCSA vision standards, is this driver
eligible for interstate certification?
A. Yes, because the better eye meets the 20/40 standard.
B. No, because the worse eye does not meet the 20/40 standard.
C. Yes, if the driver has a field of vision of at least 70 degrees in the better eye.
D. No, because both eyes must have at least 20/40 corrected.
Answer: A. Yes, because the better eye meets the 20/40 standard.
FMCSA requires corrected visual acuity of at least 20/40 in one eye (the better eye) and
a field of vision of at least 70 degrees in that eye. The worse eye has no minimum
standard. Option B is incorrect because the worse eye is not required to meet 20/40.
Option C is correct but the main criterion is acuity. Option D is false.

, 5. A driver with a BMI of 38 kg/m² and a neck circumference of 18 inches is being
evaluated for sleep apnea. Which of the following screening tools is most appropriate
for determining whether a sleep study is required under FMCSA recommendations?
A. STOP-Bang score.
B. Epworth Sleepiness Scale.
C. Berlin Questionnaire.
D. Polysomnography directly.
Answer: A. STOP-Bang score.
FMCSA recommends using the STOP-Bang questionnaire as a screening tool for
obstructive sleep apnea in drivers with BMI 35 and neck circumference 17 inches
(men). A high STOP-Bang score indicates need for sleep study. The Epworth Sleepiness
Scale is a symptom measure, not a screening tool. The Berlin Questionnaire is less
commonly used in DOT exams. Polysomnography is diagnostic, not screening.
6. A driver has a history of myocardial infarction 3 years ago. He is asymptomatic,
has an ejection fraction of 50%, and is on aspirin, beta-blocker, and statin.
According to FMCSA cardiovascular guidelines, what is the minimum waiting
period post-MI before certification can be considered?
A. 6 months.
B. 1 year.
C. 2 years.
D. No waiting period if the driver is asymptomatic.
Answer: B. 1 year.
FMCSA requires a 1-year waiting period after myocardial infarction before
certification, provided the driver is asymptomatic and has no evidence of ischemia or
arrhythmia. Option A is too short; option C is for multiple MIs or complicated cases;
option D is incorrect because a waiting period is mandated.
