Do any other barns have to get sleep apnea studies done when they get their DOT physical? I had my 2 year DOT physical this past week and the physician measured my neck (17 inches) and told me that I may have to get a sleep study done. It turned out my BMI was 32 and my blood pressure was low so I did not have to get it done this time. The physician gave me a 2 year card but told me to expect to have to do the study next time because it was going to be mandatory soon. Is anyone else hearing this?
