No — and that is the single most misunderstood fact about the DOT physical. FMCSA and FRA published a joint advance notice of proposed rulemaking on moderate-to-severe obstructive sleep apnea (OSA) on March 10, 2016 — and officially withdrew it on August 8, 2017. No mandatory testing rule ever existed, and none exists in 2026.
| Date | What happened |
|---|---|
| January 2015 | FMCSA issues the OSA Bulletin to medical examiners — guidance, not regulation |
| March 10, 2016 | FMCSA + FRA publish the joint ANPRM on OSA (81 FR 12642) |
| 2016 | Medical Review Board issues screening recommendations (BMI thresholds) — never adopted |
| August 8, 2017 | ANPRM withdrawn — no sleep apnea rule |
| 2026 | Still no regulation; examiners use guidance + professional discretion |
What does exist is 49 CFR 391.41(b)(5): a driver must have no respiratory dysfunction likely to interfere with the ability to control and drive a CMV safely. That one sentence gives the certified medical examiner broad discretion — which is exactly why two examiners can treat the same driver completely differently.
Since there is no rule, most examiners lean on the 2016 Medical Review Board recommendations — guidance FMCSA never turned into law:
| Screening trigger (guidance, not regulation) | Threshold |
|---|---|
| BMI — automatic referral suggested | 40+ |
| BMI — referral if 3+ risk factors also present | 33–40 |
| Neck circumference (a risk factor) | over 17 in (men) / 15.5 in (women) |
| Other risk factors | age 42+, hypertension, type 2 diabetes, loud snoring, witnessed apneas, daytime sleepiness, small airway |
Practical translation: a driver with BMI 36, a 17.5-inch neck and blood-pressure medication is a classic referral candidate at many clinics. A driver with BMI 32 and no other flags usually is not. But because it is discretion, some occupational-medicine chains apply stricter in-house protocols than an independent examiner would. What you say matters too: answering "yes" to "do you feel tired during the day?" on the health history is a referral trigger you handed over yourself — never lie on the form (that is a federal document), but do not volunteer vague complaints either.
| Option | Typical cash price | Notes |
|---|---|---|
| Home sleep apnea test (HST) | $150–$500 | 1–2 nights with a portable sensor at home; accepted by most examiners |
| In-lab polysomnography | $1,000–$3,500 | Overnight in a sleep lab; hospital-based centers can bill far more |
| CPAP compliance report | usually $0 | Generated by the machine / provider app |
If your examiner refers you, ask specifically whether a home test is acceptable — for routine OSA screening it almost always is, and the price difference is 5–10x. Health insurance often covers the study when a physician orders it; many owner-operators still pay cash for an HST because it is faster than the insurance authorization loop.
The de-facto standard — borrowed from Medicare coverage criteria and applied almost universally — is the "4/70 rule": at least 4 hours of use per night on 70% of nights, measured over a 30- or 90-day window. Modern machines log everything automatically and upload it to the provider's cloud.
| Outcome | Typical situation |
|---|---|
| 2-year card (regulatory max, 49 CFR 391.45) | No OSA suspicion, no conditions requiring monitoring |
| 1-year card | Diagnosed OSA, treated with CPAP, compliant — annual recheck is standard practice |
| 3-month card | Sleep study ordered but not yet done, or initial CPAP compliance not yet proven |
| Not certified | Untreated moderate-to-severe OSA, refusal to treat, or failed compliance |
The 3-month card is not punishment — it is a bridge that keeps you earning while you complete the study and the first compliance window. The real financial damage comes from ignoring it and letting the card expire.
Yes — no regulation forces you onto a sleep lab bed. But understand the consequences chain: refuse → examiner declines to certify (or issues a short card that then expires) → no valid medical certificate → you cannot legally drive a CMV. "Examiner shopping" stopped being a quiet option too: since June 23, 2025, under the National Registry II rule, every CDL exam result transmits electronically to FMCSA by the next calendar day — a second examiner sees a system where your last result already lives.
A downgraded CDL means re-applying through your state to restore the commercial class — days or weeks of not driving. For an owner-operator that is a truck payment missed over a calendar-reminder failure. This is why medical-certificate expiration tracking is a standard part of the driver qualification file — see our DQ file audit checklist — and one of the items TruckerNavi monitors for clients in every Safety Compliance plan.
Sleep apnea itself is between you, your doctor and the examiner. What a compliance provider does is make sure the paperwork never ambushes you: TruckerNavi Safety Compliance plans (from $189/month) track every driver's medical certificate expiration inside the DQ file, send renewal reminders well before the 60-day downgrade mechanics can start, and keep your files audit-ready. If a roadside inspection or audit is what worries you next, start with our guide to DOT inspection levels.
Call (315) 871-0833 — med-cert expiration tracking & DQ file auditNo. The 2016 ANPRM was withdrawn in August 2017; there is no FMCSA sleep apnea regulation. Examiners use guidance and discretion under 49 CFR 391.41(b)(5).
Guidance only: BMI 40+ suggests automatic referral; BMI 33–40 plus 3+ risk factors; neck over 17 in (men) / 15.5 in (women). Thresholds vary by examiner.
Home sleep test: $150–$500 cash. In-lab polysomnography: $1,000–$3,500, sometimes more at hospital labs. Ask for the home test first.
The 4/70 rule: at least 4 hours per night on 70% of nights over a 30- or 90-day window, documented by the machine's report.
Study or compliance pending = 3-month card. Treated and compliant = 1-year card typically. Maximum for anyone is 24 months.
Yes, but the examiner can decline to certify you, and since June 23, 2025 all exam results transmit electronically to the National Registry — the result follows you.
Your state licensing agency must downgrade your CDL within 60 days of non-certified status. Getting the CDL back means a new exam plus state paperwork.
Safety Compliance plans from $189/month track med-cert expirations in DQ files and send reminders before a lapse. Call (315) 871-0833 — Russian and English.
