What does "mandatory directive" mean under NORAC rules?

A "mandatory directive" under NORAC rules refers to a command that must be followed without deviation. This term emphasizes the importance of adherence to specific instructions or commands that are critical for safety and effective operation within the rail system. Mandatory directives are non-negotiable and are essential for ensuring compliance with safety protocols and operational standards.

By requiring strict compliance, these directives help maintain a uniform understanding of procedures among all personnel, thereby minimizing the risk of errors that could lead to accidents or unsafe conditions. In contrast, suggestions, recommendations, or optional guidelines may allow for flexibility and personal judgment, but mandatory directives are explicitly designed to enforce a specific course of action that all must follow.
