If a driver's blood pressure falls below Stage 1 after a period of Stage 2, what is the subsequent medical card duration?

When a driver's blood pressure falls below Stage 1 after being classified in Stage 2 hypertension, it indicates an improvement in the driver's cardiovascular health. The Federal Motor Carrier Safety Administration (FMCSA) guidelines provide specific durations for medical certifications based on the stability and control of hypertension.

In this case, an annual evaluation is warranted because the driver has a history of hypertension (Stage 2) but has since managed to lower their blood pressure to a healthier level (below Stage 1). This shows that while the driver's condition has improved, ongoing monitoring is essential to ensure that their blood pressure remains stable within safe limits. The annual evaluation allows the medical examiner to reassess the driver's condition, ensuring their safety on the road and compliance with medical standards.

Other options suggest shorter evaluation periods, but given the past history of Stage 2 hypertension, a more extended follow-up is warranted to ensure the driver maintains their health and can perform their driving duties safely.
