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.

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

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.
