Does sleep apnea disqualify you from driving a truck?
No, treated sleep apnea usually does not disqualify you. Untreated sleep apnea can be a problem because it increases crash risk from fatigue and daytime sleepiness.

How examiners screen for sleep apnea at a DOT physical
Examiners may review BMI, neck size, blood pressure, snoring, witnessed pauses in breathing, daytime sleepiness, and your prior diagnosis history.
What happens if the examiner suspects sleep apnea
You may be asked to complete a sleep study. Depending on risk and symptoms, the examiner may issue a short certificate or wait for sleep study results before certifying.
CPAP compliance — what you need to prove
Bring a CPAP compliance report. A common benchmark is at least 4 hours per night on 70% of nights, though the examiner makes the final call.
Getting your medical card with treated sleep apnea
Bring your compliance report, sleep doctor notes, and current equipment settings. Treated drivers often receive a 1-year certificate so compliance can be checked annually.

What if you refuse a sleep study?
You can refuse, but the examiner can also refuse to certify you if they believe untreated sleep apnea makes commercial driving unsafe.
