DOT Sleep Apnea Screener for California Truck Drivers
Quick answer
The FMCSA flags CDL holders with risk factors like BMI over 35, neck size over 17 inches, witnessed apneas, hypertension, or daytime sleepiness for sleep apnea testing during the DOT physical. This screener checks the same factors a DOT medical examiner uses. A score of 2 or more typically triggers a sleep study referral and a 90-day temporary medical card.
California has roughly 250,000 active CDL holders. Untreated obstructive sleep apnea roughly doubles crash risk for commercial drivers, which is why the FMCSA requires testing when risk factors are present. The good news: a positive screen and even a positive diagnosis are not disqualifying. What matters is starting treatment and showing CPAP compliance. This screener takes two minutes and will tell you what to expect at your next DOT physical.
Frequently asked
Will a positive sleep apnea diagnosis end my driving career?
No. A positive diagnosis is not disqualifying. What matters to the medical examiner is documented treatment and compliance. Most drivers stay on the road through their 90-day temporary card while they start therapy, then graduate to a standard 1- or 2-year card.
What does chain of custody mean for DOT sleep testing?
Chain of custody means the device, the recording, and the interpretation are controlled and documented at every step. Without it, nothing stops a driver from handing the device to a non-snoring partner overnight. The DOT medical examiner who decides on your long-term card needs to verify the data came from you, on this device, on these dates.
How long does it take from order to certification decision?
Typically 10 to 14 days. Device ships in 2 to 3 business days, you wear it for 2 consecutive nights, mail it back, and the report goes to your physician and DOT medical examiner within 3 to 5 business days of return. Well within the 90-day temporary card window with no missed driving time.
Does insurance cover this?
Most carrier health plans, Medicare, and major commercial plans cover home sleep apnea testing for CDL holders. The CPT code is typically 95800 or G0398 (Medicare). If you do not have insurance, ask about a self-pay rate.
