The BMI Tables

Aim for a Healthy Weight:

We should become familiar with this federal medical requirement : I have encountered two separate issues regarding the BMI (Body Mass Index) of drivers affect by these regulations.

When a CDL driver is required to renew their Medical Examiners Certificate, the driver will now be checked for complications with their bodies ability to exchange oxygen. If the driver appears to be overweight during their examination, a measurement of the neck circumference will be taken along with the height and body weight.

From that data their BMI will be established. If the examiner determines the driver is not in a safe range, the medical examiner may order a sleep study for “Sleep Apnea”  before a certified renewal card can be issued. Thus, disqualifying an existing driver or a potential candidate from driving a CDL truck.

The medical examiner may choose to issue a temporary 90 day card and require the sleep study before the 90 days has expired. If the Study is NOT performed, the driver will not be issued a renewal card.

It is also rumored that sometime around 2012-2014, driver’s medical information will be electronically filed and stored with The Federal DOT.  Pass or Fail.

THE POINT:  Borderline CDL drivers need to improve and maintain their health. DOT studies show, people who suffer from Sleep Apnea are 2 to 7 times more likely to fall asleep behind the wheel if not treated.


If overweight is is possible to be disqualified by the Medical Examiner under  . . . FMSCSR

The overall health of our employees is very important.
