What is the maximum allowable blood pressure for a commercial driver during the medical examination?

The maximum allowable blood pressure for a commercial driver during the medical examination is 140/90 mmHg. This threshold is set based on guidelines designed to ensure that commercial drivers are fit for duty and do not have health conditions that could impair their ability to operate a vehicle safely.

Blood pressure readings are important indicators of cardiovascular health, and maintaining a blood pressure at or below this level helps to mitigate risks associated with hypertension, such as heart disease or stroke, which could have critical implications while driving.

While the other options present varying degrees of blood pressure readings, they exceed the acceptable limit. For instance, 160/100 mmHg and 180/110 mmHg are both considered stages of hypertension that could compromise a driver's health and safety on the road. The normal blood pressure of 120/80 mmHg is ideal, but the minimum standard for commercial drivers allows slightly higher readings up to 140/90 mmHg while still ensuring safety standards are met.
