📋 FMCSA Sleep Apnea Guidance

The Federal Motor Carrier Safety Administration (FMCSA) recognizes obstructive sleep apnea as a condition that can impair safe driving. Medical examiners use a combination of factors — including BMI, neck circumference, and reported symptoms — to determine whether a driver requires further sleep evaluation. This tool helps you understand those same factors based on published FMCSA guidance. It is not a medical examination and does not determine your fitness for duty.

Important: This summary restates your self-reported inputs alongside published FMCSA guidance factors. It does not predict whether a medical examiner will require a sleep study, determine your fitness for duty, or constitute medical advice. Only a DOT-certified medical examiner can make those determinations. If you have concerns about sleep apnea, speak with your healthcare provider or medical examiner before your next physical.

Published research

What the research shows about drivers and sleep apnea

These are population-level findings from peer-reviewed research. They describe patterns across study populations — not predictions for any individual.

OSA prevalence in commercial drivers

Studies estimate obstructive sleep apnea affects 28–33% of commercial truck drivers — significantly higher than the general population rate of approximately 22% in adults.

Pack et al., 2006 · Tregear et al., 2009

Weight and airway risk

A 10% increase in body weight is associated with a 32% average increase in sleep apnea severity. Weight is one of the most significant and reversible contributors to sleep-disordered breathing.

Peppard et al., JAMA 2000

Neck circumference

Neck circumference at or above 17 inches in men and 16 inches in women is associated with elevated OSA risk in published research, and is one of the factors FMCSA guidance references.

For fleet operators

Offer this to your drivers

SnoreWeight can be deployed as an anonymous fleet-wide sleep health screening tool. Drivers complete the assessment privately — you see anonymized aggregate data on your workforce sleep health picture.

Anonymous screening

Drivers complete assessments privately. No individual results are shared without their consent.

DOT-aware framing

Language and factors aligned with FMCSA guidance so drivers understand the context.

White-label ready

Deploy under your fleet brand. Drivers see your company name, not SnoreWeight.
