NRCME Diabetes Mellitus Standards 2 — Questions and Answers
Question 1: Under FMCSA diabetes standards, a driver treated with insulin is generally:
- Permanently disqualified from CMV operation
- Eligible for exemption through the Federal Diabetes Exemption Program (Correct answer)
- Qualified if HbA1c is below 7%
- Qualified with a 30-day medical certificate
Correct answer: Eligible for exemption through the Federal Diabetes Exemption Program
Insulin-treated drivers may operate CMVs under the Federal Diabetes Exemption Program if they meet specific criteria.
Question 2: Which HbA1c threshold most commonly raises concern for glycemic control when evaluating CMV drivers?
- Above 5.7%
- Above 6.5%
- Above 10% (Correct answer)
- Above 8%
Correct answer: Above 10%
An HbA1c above 10% typically indicates poor glycemic control and raises significant safety concerns for CMV drivers.
Question 3: A CMV driver with Type 2 diabetes treated with metformin reports no hypoglycemic episodes. The examiner should:
- Disqualify due to diabetes diagnosis alone
- Certify if otherwise qualified with no signs of end-organ complications (Correct answer)
- Require insulin exemption documentation
- Issue only a 30-day certificate regardless
Correct answer: Certify if otherwise qualified with no signs of end-organ complications
Drivers with well-controlled Type 2 diabetes on oral agents without hypoglycemia risk may be certified if they meet all other standards.
Question 4: Proliferative diabetic retinopathy in a CMV driver is significant because it may affect:
- Hearing acuity
- Visual acuity and field of vision (Correct answer)
- Cardiovascular endurance
- Peripheral nerve reflexes only
Correct answer: Visual acuity and field of vision
Proliferative retinopathy can impair visual acuity and peripheral vision, which are critical for safe CMV operation.
Question 5: Under the Federal Diabetes Exemption Program, drivers must submit what to maintain their exemption?
- Annual physician attestation and driving record (Correct answer)
- Quarterly blood glucose logs only
- One-time application with no follow-up required
- Monthly HbA1c results
Correct answer: Annual physician attestation and driving record
Exemption holders must provide annual physician attestation confirming continued safe control and a clean driving record review.
Question 6: A driver on a sulfonylurea reports a hypoglycemic episode while driving last month. The examiner should:
- Certify normally since one episode is acceptable
- Disqualify until hypoglycemia is adequately controlled and no episodes recur (Correct answer)
- Switch driver to insulin and certify immediately
- Issue a 2-year certificate with no restrictions
Correct answer: Disqualify until hypoglycemia is adequately controlled and no episodes recur
A hypoglycemic episode while driving is a serious safety event requiring disqualification until control is demonstrated.
Question 7: Which diabetic complication most directly affects the ability to meet FMCSA peripheral sensation standards?
- Nephropathy
- Peripheral neuropathy (Correct answer)
- Retinopathy
- Gastroparesis
Correct answer: Peripheral neuropathy
Peripheral neuropathy can impair foot sensation and limb function, affecting the ability to operate pedals safely.
