What is true regarding drivers with mood disorders?

1. They may exhibit grandiosity and impulsiveness during manic episodes.

2. They will have quicker reaction times during depressive episodes.

3. They exhibit completely predictable behavior with poor judgment.

4. They may show flexibility with a decreased crash rate.

The correct answer is: They may exhibit grandiosity and impulsiveness during manic episodes.

Drivers with mood disorders can experience grandiosity and impulsiveness during manic episodes, making this a true statement. In the context of mood disorders, particularly bipolar disorder, manic episodes are characterized by elevated mood, increased energy, and erratic behavior which includes impulsivity and a sense of inflated self-esteem. This impulsiveness can lead to risky driving behaviors, such as speeding or engaging in reckless maneuvers. Such attributes can greatly affect their driving skills and decision-making abilities on the road, which is essential for maintaining safety. The other choices do not accurately reflect the behaviors associated with mood disorders. For instance, during depressive episodes, individuals typically exhibit slower reaction times rather than quicker ones. The notion of completely predictable behavior with poor judgment does not hold true for mood disorders, as their behavior can vary significantly based on the phase of their condition. Lastly, the idea that drivers with mood disorders may show flexibility with a decreased crash rate contradicts the reality that mood disorders often impair driving ability, leading to a higher crash rate due to the associated symptoms.
