Frequently Asked Questions
Will I fail my DOT physical if I have sleep apnea?
Not automatically. Sleep apnea is not on the DOT list of automatic disqualifiers (49 CFR 391.41). Mild OSA (AHI under 15) typically doesn't affect certification. Moderate-to-severe OSA (AHI 15+) requires treatment (usually CPAP) and documented compliance to maintain certification — typically a 1-year medical card subject to CPAP usage data.
How does the medical examiner check for sleep apnea?
Risk-factor screening: BMI over 33, neck circumference 17+ inches (men) / 15.5+ inches (women), reported snoring, observed apneic episodes, daytime sleepiness, or hypertension that's hard to control. If risk factors are present, the medical examiner may issue a 90-day temporary card with referral to a sleep specialist for polysomnography.
What CPAP usage data does the DOT examiner check?
Typical requirements: 70%+ usage rate (most nights), 4+ hours per night minimum. CPAP machines record this automatically and the data is downloadable as a usage report. The medical examiner reviews the report at recertification — gaps in compliance can result in a downgrade to 90-day temporary card or full disqualification.
Can I drive while waiting for CPAP titration?
If the medical examiner determined sleep apnea is impacting safety, no — the driver should not be operating until effective treatment is established. If the examiner classified the condition as 'pending evaluation,' a 90-day temporary card may be issued allowing continued operation while diagnosis and treatment occur.
How does FileFlo track sleep apnea CPAP compliance?
FileFlo's FMCSA rule-pack stores the CPAP compliance reports (PDF or CSV from manufacturer portal) alongside the driver's medical card. Annual reminder to pull updated compliance data 60 days before recertification. Per-driver tracking of usage rate and hours per night flagged against the 70%/4-hour thresholds.
