What is the maximum blood pressure level before requiring a follow-up assessment?

In the context of DOT certification and assessing commercial driver's fitness, the maximum blood pressure level before a follow-up assessment is typically set at 140/90 mm Hg. This is aligned with the guidelines from the Federal Motor Carrier Safety Administration (FMCSA), which indicate that a blood pressure reading exceeding this level on a first examination may necessitate further evaluation to determine if the individual is fit for duty. The reasoning behind this threshold is to ensure that drivers do not have undiagnosed or uncontrolled hypertension that could pose a risk while operating a commercial vehicle, potentially leading to accidents or health emergencies.

It is important to assess blood pressure readings accurately because hypertension can affect a person's ability to safely drive, increasing the risk of sudden incapacitation. A follow-up assessment may involve monitoring blood pressure over time, implementing lifestyle changes, or possibly medication management to ensure that the driver's health is maintained within safe parameters.
