For what reason would an individual with major depression or bipolar disorder be limited to a one-year maximum certification?

An individual with major depression or bipolar disorder may be limited to a one-year maximum certification primarily due to a recent suicide attempt. This is a significant factor because it directly impacts the safety and well-being of the individual and others, particularly in occupations that require attention, decision-making, and physical capability, such as driving a commercial vehicle.

When assessing the fitness of an individual for operation of a commercial vehicle, mental health stability is a key concern. A recent suicide attempt indicates that the individual may still be experiencing acute symptoms or crises, which can impair judgment, reaction times, and overall mental health functioning. Because of these risks, medical certifications for such individuals are often limited to one year, allowing for ongoing evaluation and treatment adjustments.

Other factors listed, such as being diagnosed with diabetes or one’s spouse's health condition, do not have the same direct correlation with immediate risk to safety in terms of mental health. Non-compliance with treatment could be a concern, but it does not automatically warrant a maximum one-year restriction as a recent suicide attempt does. This makes the recent attempt a more critical reason for limitation in certification duration.
