Drivers who come in to my office for a DOT physical exam often ask: “Why do I need a sleep study? DOT doesn’t require it.”
So here is the information a driver needs to know regarding if you need a sleep study or not:
The FMCSA states that DOT medical examiners should follow “best practice” guidelines when evaluating a driver for sleep apnea and ordering a sleep study. Here are the “best practice” guidelines that are recommended:
A driver with symptoms:
If the driver has one of the following 4 symptoms it is recommended that driver be tested for sleep apnea:
- Driver complains of consistent daytime sleepiness or fatigue.
- Driver has been involved in a sleep-related accident.
- Driver states that someone has observed the driver stop breathing while sleeping.
- The driver reports that he snores loudly (snoring is heard thru a wall or door).
A driver without symptoms:
If the driver has none of the above symptoms but they have multiple risk factors for sleep apnea, it is recommended that the driver be tested for sleep apnea. Here is a list of those risk factors:
-
- BMI of 33 or greater.
- Neck size of 17” or greater for a male.
- Neck Size of 16” or greater for a female.
- Driver has one or more of the following disease:
- Driver has High Blood Pressure
- Driver has Diabetes
- Driver has Heart Disease
- Driver has Hypothyroidism
- Driver has history of Stroke
- Male driver over the age of 50.
- Female driver post-menopausal.
- Driver has a Mallampati Score of 3 or 4.
Best practice recommendations for drivers that have had a prior sleep study:
A second sleep study is recommended if the driver has developed additional risk factors since the first study was done, or the driver has had a 10% increase in weight.

I was told I need a sleep study before I get my card, but he gave me a three month card. Imho the dr was a quack, conveyor belt Dr. Do I have to get a sleep study done or can I get a second, I had one done in 2015 and have since lost weigh. I’m 52, 6’3″, 18in neck, and 300lbs. I sleep just fine at night, and have never had an issue.
@ Scott
Go get a second opinion.
If I get my bmi under 33 but I have been diagnosed with obstructive sleep apnea can I come off the cpac?
@ Jimmy v
That would be your doctors call, not DOT/FMCSA.
So I had a sleep apnea test done and the AHI is 11.5 which is boarder line sleep apnea do I still need treatment ? I’m on a strict diet and fmcsa says olny moderate and severe sleep apnea needs treatment not mild case
@ Eric
The examiner must take a much larger view of your condition. If you have no other symptoms that indicate OSA, then you should be fine.
I checked off “sleep apnea” on the questionarre due to my PCP mentioning it in the past. Of course, this brought up a red flag to the NP doing my exam. She issued me a 6 month card. Fast forward to last week when I finally did an at home study. The study came back as “Quite severe OSA” does this disqualify me in the state of Rhode Island? I was told that anything above moderate will.
@ Jamie
Not if you are using a cpap with a 70% compliance record. According to the federal DOT/FMCSA.
Doctor came in the office and said he was over worked and been busy all day he hasn’t had a chance to change his gloves, now that’s exactly what the doctor said when he came in the room, then looked at my daughter and said you have to get a sleep study, nothing else, never asked her anything about herself. I believe this is a bad dit doctor that’s just tired, so being she has to wait 5 months to get one where and how is she to pay her bills? Did I mention, no health complications at all.
@ Dawn
Simply go somewhere else and get a proper medical examination. Sleep studies are not mandatory for DOT/FMCSA unless there are a multitude of signs and symptoms.
I was told I needed a sleep study even if I already had one in 2015 I may benefit from a cpap but not required to have one.
@ Denise
Go get a second opinion elsewhere.
In 2011 I was diagnosed with sleep apnea. I have been taking Modafinal for 6 years and have my compliance with CPAP machine checked yearly . Will this be a problem.
Thank you
@ Samantha
You should be fine. Bring documentation and readouts with you to your next exam.
I have been recommended by my companies DOT Doctor to have a sleep study. He only gave me a 90 day card. My temporary DOT Card expires Aug 6, 2021. I finally got in to see the sleep study specialist who is awaiting approval from insurance. The Doctor said I should have sleep study done but won’t have the results back until after my DOT Card expires. Can the DOT Doctor give me an extension so I can still work until my results come in?
@ Bobby
You will have to check with the CME who requested the sleep study.
