NRCME - National Registry of Certified Medical Examiners Drug Abuse and Alcoholism Questions and Answers

Question 1

A CMV driver informs the medical examiner that he had a positive DOT drug test for an illicit substance six months ago. He states he has since completed all necessary steps to return to work. What documentation must the driver provide for the medical examiner to consider certification?

Accepted Answer

A completion letter from a Substance Abuse Professional (SAP) and a negative return-to-duty drug test result.

Answer

According to 49 CFR Part 40, a driver who fails a DOT drug test must be evaluated by a qualified Substance Abuse Professional (SAP), complete the prescribed education or treatment, and pass a directly observed return-to-duty drug test. The medical examiner must verify that this federally mandated process has been successfully completed before issuing a medical certificate.

Question 2

A driver presents for an examination and has a valid state-issued card for medical marijuana, which is a Schedule I controlled substance under federal law. According to FMCSA regulations, what is the correct determination?

Accepted Answer

The driver is disqualified because the use of any Schedule I substance is medically disqualifying, regardless of state law.

Answer

The FMCSA is a federal agency and adheres to federal law, which classifies marijuana as a Schedule I controlled substance. The use of any Schedule I substance is an absolute disqualification for a commercial driver under 49 CFR § 391.41(b)(12). State laws permitting medical or recreational marijuana use do not exempt CMV drivers from this federal regulation.

Question 3

Which of the following statements regarding alcohol use by a CMV driver is correct according to FMCSA regulations found in 49 CFR §392.5?

Accepted Answer

A driver with a blood alcohol concentration (BAC) of 0.03% must be removed from safety-sensitive duties for 24 hours.

Answer

According to 49 CFR §382.505, a driver with a confirmed alcohol concentration of 0.02% or greater but less than 0.04% must be immediately removed from safety-sensitive functions for at least 24 hours. Consuming alcohol within four hours of going on duty is prohibited, and possession is not allowed unless it is part of a manifested cargo shipment. A BAC of 0.04% or greater is a violation requiring the full return-to-duty process.

Question 4

A 50-year-old driver applicant reports a history of alcoholism. He states he has been sober for 10 years, regularly attends support group meetings, and has never had a DOT alcohol violation. He presents no signs of current alcohol abuse or related medical complications during the examination. What is the most appropriate action for the medical examiner?

Accepted Answer

Certify the driver for up to two years if the examiner determines the condition is stable and the driver does not pose a risk.

Answer

A remote history of alcoholism is not automatically disqualifying. If the examiner determines through the health history and physical exam that the driver has demonstrated a long period of sobriety and stability, and there are no associated medical conditions that would interfere with safe driving, the driver can be certified. The decision rests on the medical examiner's clinical judgment, and a full two-year certification is permissible.

Question 5

A driver is enrolled in a methadone maintenance program for a past opioid addiction. What is the driver's qualification status according to current FMCSA guidelines?

Accepted Answer

The driver is disqualified.

Answer

Although recent guidance has indicated that methadone is no longer listed as an absolute disqualifier in the Medical Advisory Criteria, its use remains highly scrutinized. Historically and in practice, use of methadone for opioid addiction treatment is considered medically disqualifying by the FMCSA because it is a narcotic that can impair the cognitive skills needed to operate a CMV safely. While the ME must make an individual assessment, certification is exceptionally rare and generally not granted.
