Frequently Asked Questions
The Frequently Asked Questions (FAQs) are questions and answers about Compliance,
Safety, Accountability (CSA) that the Federal Motor Carrier Safety Administration
(FMCSA) compiled to assist the public. As questions come in through the website,
FMCSA adds them to the database along with their answers. If you do not see your
question or topic addressed, please
by submitting a feedback form. We will respond to you directly and consider your
question for inclusion in the FAQs.
The FAQ area has recently been enhanced. Users can now search FAQs by stakeholder

Are there new regulations regarding a driver's body mass index (BMI), body fat ratio,
weight, neck size, and sleep apnea?
Despite rumors to the contrary, no. While research was recently released stating
that a driver's BMI is a risk factor for identifying sleep apnea, neither the Federal
Motor Carrier Safety Administration (FMCSA) nor the Compliance, Safety, Accountability
program currently has any rules that restrict who can be a commercial motor vehicle
driver based on BMI or weight, or neck size. For more information view FMCSA’s Spotlight on Sleep Apnea.
