NRCME Medical Conditions and Guidelines 5 — Questions and Answers
Question 1: A driver discloses use of medical marijuana legally prescribed in their state. Under FMCSA regulations, how should the examiner proceed?
- Certify if the driver's physician confirms it does not impair driving
- Certify for 6 months with quarterly drug testing
- Disqualify; marijuana remains a Schedule I substance federally regardless of state law (Correct answer)
- Require a drug test and certify if negative on DOT urine screen
Correct answer: Disqualify; marijuana remains a Schedule I substance federally regardless of state law
Marijuana is Schedule I federally and prohibited for CMV drivers under DOT regulations regardless of state medical marijuana laws.
Question 2: A 58-year-old male driver has an ECG showing left bundle branch block (LBBB) discovered incidentally. He is asymptomatic with no cardiac history. What is the appropriate next step?
- Certify normally; LBBB is a benign finding in older adults
- Disqualify permanently due to conduction system disease
- Refer for cardiovascular evaluation before certifying (Correct answer)
- Certify for 6 months and repeat ECG
Correct answer: Refer for cardiovascular evaluation before certifying
New LBBB warrants cardiology evaluation to rule out underlying structural heart disease before CMV certification.
Question 3: Under FMCSA guidelines, which condition requires the medical examiner to check the Federal Diabetes Exemption or consult a specialist before issuing a certificate?
- Type 2 diabetes controlled with metformin alone
- Type 2 diabetes controlled with a sulfonylurea
- Type 1 diabetes controlled with insulin pump (Correct answer)
- Type 2 diabetes controlled with diet and exercise only
Correct answer: Type 1 diabetes controlled with insulin pump
Insulin-treated diabetes (including pump therapy) requires enrollment in the FMCSA ITDM Exemption Program before interstate CMV certification.
Question 4: A driver with a history of coronary artery bypass surgery 14 months ago is asymptomatic, has normal stress test results, and an ejection fraction of 58%. What should the examiner do?
- Disqualify; all post-CABG drivers require a 2-year waiting period
- Certify for 1 year with cardiologist clearance documentation (Correct answer)
- Certify for 2 years as the driver is asymptomatic
- Refer to cardiologist but do not certify until 24 months post-surgery
Correct answer: Certify for 1 year with cardiologist clearance documentation
Post-CABG drivers may be certified for 1 year with documented cardiologist clearance confirming adequate cardiovascular function.
Question 5: Which neurological condition, if currently symptomatic, would MOST likely disqualify a CMV driver under FMCSA standards?
- History of migraine without aura, currently well-controlled
- Multiple sclerosis with active relapsing episodes causing visual disturbance (Correct answer)
- History of carpal tunnel syndrome post-surgical release
- Mild essential tremor not affecting hand function
Correct answer: Multiple sclerosis with active relapsing episodes causing visual disturbance
Active MS with relapsing episodes causing visual or motor symptoms represents a current impairment that would disqualify a CMV driver.
Question 6: A driver presents with a BMI of 42 and reports no symptoms. The examiner suspects he may have undiagnosed obstructive sleep apnea. What is the best course of action?
- Certify for 2 years; BMI alone is not disqualifying
- Disqualify until OSA is ruled out by sleep study
- Certify for 1 year and recommend a sleep evaluation
- Refer to a sleep specialist and issue a 90-day certificate pending evaluation (Correct answer)
Correct answer: Refer to a sleep specialist and issue a 90-day certificate pending evaluation
When there is clinical suspicion for OSA, a short-term certificate pending sleep evaluation is the appropriate safety-focused approach.
Question 7: A driver has a functional monocular vision (one eye with 20/200 uncorrectable). Can this driver be certified for interstate CMV operation?
- Yes, if the functioning eye meets 20/40 acuity and field of vision standards
- Yes, with a vision exemption from FMCSA
- No; FMCSA requires both eyes to meet vision standards for interstate operation (Correct answer)
- Yes, with a skills performance evaluation certificate
Correct answer: No; FMCSA requires both eyes to meet vision standards for interstate operation
FMCSA requires that each eye individually meet the vision standard; functional monocular vision disqualifies a driver from interstate CMV operation.
