A driver has a blood pressure of 165/105 mm Hg at initial certification and 135/85 mm Hg upon recheck. What is the appropriate action for the medical examiner?

The appropriate action for the medical examiner is to certify the driver for one year after performing a new DOT examination. This course of action is justified because the driver initially presented with elevated blood pressure, which is classified as hypertension. The revisited blood pressure reading is significantly improved and falls within the normal range, suggesting that the driver may have controlled his hypertension effectively.

Medical examiners are required to ensure that drivers meet specific health criteria to operate commercial vehicles safely. In this case, a new DOT examination is warranted to confirm the driver's current health status and ensure the changes in blood pressure are stable and consistent over time. Certifying for one year reflects confidence in the driver’s ability to maintain their health and continue operating a commercial vehicle safely, while also allowing for periodic monitoring of their condition.

This option supports the principles of medical fitness and safety for commercial driving, balancing the need for thorough health evaluations while recognizing improvements in the driver’s condition.
