What should all crew members do with the mandatory directive before acting upon it?

All crew members must read and understand the mandatory directive to ensure safety and compliance with operational protocols. This understanding is crucial because directives often contain essential information about train operations, signal changes, or safety procedures that directly impact the performance of their duties. By ensuring that everyone involved has a clear grasp of the directive, the team can work more effectively and mitigate the risk of accidents or miscommunications.

In a collaborative environment such as a train crew, relying solely on one person—like the dispatcher or the engineer—to comprehend the information could lead to gaps in knowledge. Each member of the crew plays a vital role, and their collective understanding of directives is necessary to ensure that all safety measures and operational procedures are meticulously followed.
