Final answer:
To maintain a daily log, you must have an updated log up to your last change in duty status, copies of your daily log for the work cycle, and any supporting documents from your trip, as all elements are crucial for creating a complete and accurate record.
Step-by-step explanation:
If you are required to keep a daily log, what must you have in your possession? The answer is d. All of the above. This is because maintaining a comprehensive daily log is important for various reasons, including legal compliance, safety, and work-hour tracking. Specifically, you must have:
- A log that is updated to your last change in duty status.
- Copies of your daily log for your work cycle. Keeping these allows for easy reference and verification of work hours.
- Any supporting documents you have been issued during your trip, such as receipts, bills of lading, or trip reports. These documents often provide the necessary details to corroborate the log entries.
Combining the log updates, copies of past logs, and supporting documents create a thorough record that can prove invaluable in many situations involving compliance checks or audits.
