What constitutes a complete track warrant record?

• A. All required fields (identification, segment boundaries, times, speed, direction, special instructions) plus the crew's acknowledgment
• B. The crew's acknowledgment only
• C. The dispatcher's authorization stamp
• D. All required fields plus the crew's acknowledgment

Answer: (D)

A complete track warrant record is built from two essential parts: every required field and the crew’s acknowledgment. The required fields spell out who is authorized, the exact segment boundaries, the applicable times, the maximum speed, the direction, and any special instructions. But having those fields filled isn’t enough by itself—the crew must acknowledge receipt and understanding of those terms so there’s a clear, verifiable commitment to comply. Together, all required fields plus the crew’s acknowledgment make the record complete and enforceable. The dispatcher’s authorization stamp isn’t the element that completes the record, and having only the acknowledgment or only the fields would leave gaps in accountability and safety.
