Here are the medical guidelines according to the Federal Motor Carrier Safety Regulations (FMCSRs). Note that employers are allowed to impose more stringent medical requirements.
Drivers with Type 1 or Type 2 diabetes, or kidney disease require treatment if their blood pressure rises above 130/80, since they already have a high risk of heart disease.
Can I get a DOT medical card if I have hypertension?
See blood pressure requirements for stages of hypertension. The medical examiner may require clearance from your treating physician before you can be considered for certification.
What if I’m on blood pressure medication?
Taking blood pressure medications will reduce your DOT medical certificate to one year. Your blood pressure must be controlled and be below 140 / 90 at the time of your DOT examination.
Also, it is very helpful, if you have a note from your treating physician that states that your condition is being treated and that the treatment has been shown to be effective, safe and your condition is stable. This information helps the DOT examiner determine if you are medically fit to operate a commercial motor vehicle for the designated time frame of your DOT medical certificate.
What if I don’t normally have high blood pressure, but I have “white coat syndrome”?
First off, we understand that this is a very real concern for some drivers. If you have “white coat syndrome”, tell the examiner, and ask to have multiple BP’s taken. He should be taking 2-3 readings anyhow, especially if you say so up front.
