Sleep apnea and truck drivers

Updated October 2026

Untreated sleep apnea can cause daytime sleepiness, a real safety risk behind the wheel.

At the exam

There isn't a single federal sleep apnea rule, so examiners use their judgment and may ask for a sleep study if they see risk factors.

If you're diagnosed

Many drivers keep their cards with treatment such as CPAP. Use it consistently, and bring a compliance report from your machine to your exam.
