- Driver HOS: per-day logs per driver, with the ELD winning over manual entries for any day it has data.
- HOS Violations: 11-hour, 14-hour, 30-minute break and cycle violations by driver, with the day to open.
- Log Edits and Unassigned HOS: edits awaiting driver confirmation and unassigned driving to claim or annotate. Review weekly.
- Diagnostics & Malfunctions: open ELD malfunction and data-diagnostic events; a malfunction starts the 8-day paper-log clock.
- HOS Audit Transfer and Duty Status Summary produce the records an officer or auditor asks for.
Federal rules require a back-up copy of ELD records for six months on a separate device (49 CFR 395.22). Tacit OS storage is that second copy, and it stays with you if you change ELD vendors.
