The Dispatcher may direct addressee(s) to add additional line 2 authorities to a __________ Form D which is still in effect.

• A. Verbal instruction
• B. Written directive
• C. Specified Direction
• D. Authorized to reverse

Answer: (C)

When a Form D is in effect, the dispatcher can add extra permissions or restrictions known as line 2 authorities, but this can only be done to a Form D that is a Specified Direction. The Specified Direction type is the one designed to be active and adaptable, allowing modifications to its authorized scope without issuing a new directive. Verbal instructions and written directives aren’t designed to carry in-effect amendments to line 2, and “Authorized to reverse” isn’t a form type that would take on additional line 2 authorities. So the best fit is a Specified Direction Form D.
