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.

My new company doctor told me I need a sleep study done and gave me a 3 month certificate expiring 9/22 but my original certificate was for 2 years expiring 3/24. I didn’t take the job. Which certificate is valid.
Also can I go back to the first Dr and get another DOT physical if the 2nd one is valid
Did you ever find out am on the same problem as you cab you let me know what happen please
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.
