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.
- A driver with a BP of less than 140 systolic and less than 90 diastolic may be medically certified to drive for a two-year period.
- A driver with a BP of 140 – 159 systolic and /or a BP of 90-99 diastolic, has stage 1 hypertension, and may be medically certified to drive for a one-year period. Certification examinations should be done annually thereafter and should be at or less than 140/90.
- A driver with a a BP of 160-179 systolic and/or a BP of 100-109 diastolic, has stage 2 hypertension, and is a candidate for antihypertensive drug therapy. The driver is given a one-time certification of three months to reduce his or her blood pressure to less than or equal to 140/90. Provided treatment is well tolerated and the driver demonstrates a BP value of 140/90 or less, he or she may be re-certified for one year from the date of the initial exam. The driver is certified annually thereafter.
- A driver with a BP at or greater than 180 systolic and / or 110 diastolic has stage 3 hypertension and is disqualified. The driver may not be qualified, even temporarily, until blood pressure is reduced to equal to or less than 140/90 and treatment is well tolerated. The driver may be certified for 6 months and biannually (every 6 months) thereafter if at recheck BP is equal to or less than 140/90.
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.
