What is the maximum certification period allowed for a patient with a history of major depression?

The maximum certification period allowed for a patient with a history of major depression is one year. This policy is in place due to the nature of major depression, which can be variable and unpredictable in its course and severity. Medical professionals must ensure that patients are stable and effectively managed, as their condition can significantly impact their ability to safely operate commercial vehicles. Therefore, more frequent evaluations are necessary to monitor any changes in the patient's mental health status and ensure their fitness for duty.

In this context, one year allows for regular assessments to ensure that any issues can be identified and managed promptly, reducing risks associated with untreated or inadequately managed mental health conditions.
