If a driver is on medications that likely impair their functionality, what should be the result regarding certification?

When considering certification for a driver on medications that are likely to impair functionality, the most responsible course of action is to not certify the driver. The primary concern is the health and safety of both the driver and the public. If medications have the potential to cause impairment—such as drowsiness, reduced reaction times, or cognitive issues—it creates significant risks when operating a commercial vehicle.

The role of the medical examiner is to assess whether a driver meets the necessary physical and mental standards set by the FMCSA. If a driver is taking medications that could negatively affect their ability to perform safely, it's crucial to prioritize safety by withholding certification until they are stabilized on a regimen that allows them to operate a vehicle without impairment or until they are cleared by a qualified medical professional to do so.

Certifying with a warning, for a short duration, or with follow-up required may present risks if the driver is not capable of safely performing their job functions. Safety must always be the top priority in these assessments.
