  1. A driver who is under the influence of a prescription drug that impairs driving is:

    Answer: Subject to the same penalties as if intoxicated

    Operating a CMV while impaired by any substance — including legal prescriptions — violates FMCSA regulations and carries the same penalties as intoxication.

  2. Under FMCSA rules, a driver found to have a blood alcohol concentration (BAC) of 0.04 or greater while on duty must:

    Answer: Be placed out of service for 24 hours

    A BAC of 0.04 or greater places the driver out of service for 24 hours; the 0.04 limit is lower than the standard 0.08 for CMV drivers.

  3. What must a medical examiner list on the Medical Examiner's Certificate if a driver requires corrective lenses?

    Answer: A restriction stating corrective lenses are required

    If a driver uses corrective lenses to meet vision standards, the MEC must include a restriction requiring their use while driving.

  4. Which condition is an absolute disqualification under FMCSA medical standards, with no waiver available?

    Answer: Loss of a foot or leg without a prosthesis and no exemption

    Loss of a foot or leg without both a prosthesis and an FMCSA exemption is an absolute disqualification for CMV operation.

  5. How must a driver's medical certificate information be handled after the FMCSA Medical Registry rule took effect?

    Answer: Medical examiners electronically submit results to FMCSA's National Registry

    Certified medical examiners must electronically submit examination results to FMCSA's National Registry within 24 hours of completing the exam.

  6. What is the FMCSA requirement for a driver who has a medical condition that could cause sudden incapacitation?

    Answer: The driver is disqualified from CMV operation

    Any condition that may cause sudden incapacitation — such as uncontrolled epilepsy or unpredictable syncope — is disqualifying under FMCSA medical standards.
