A truck driver’s record of duty status is one time-based record. Dispatch messages, bills of lading, itineraries, fuel and expense receipts, toll records, gate entries, mobile communications, and location records may document parts of the same trip from different systems. A useful review places each source on a common timeline while preserving its original time, timezone, author, system, and limitations.

A record-of-duty-status entry and a supporting document describe related time periods from different systems; a match or mismatch is a question for reconciliation, not a standalone finding about fatigue, compliance, or crash responsibility.

Identify the duty-status record before comparing it

  • Driver, carrier, date, truck or tractor and trailer numbers, co-driver, shipping-document number, terminal, and stated time standard
  • Electronic logging device file, display, printout, transfer output, paper log, short-haul time record, malfunction record, or another identified format
  • Original record, later edit, driver certification, carrier annotation, unidentified-driving assignment, diagnostic event, and malfunction event kept as different entries
  • Export date, person or system supplying the record, file name, page count, date range, and any missing segment or unreadable field

FMCSA’s General Information About the ELD Rule explains that the rule sets device and record requirements for drivers who must prepare records of duty status and addresses supporting documents and driver harassment. The applicable requirements and exceptions depend on the carrier, vehicle, trip, driver, and time period.

Catalog supporting documents by source category

FMCSA’s Supporting Documents guidance describes records generated or received in the ordinary course of business that may be used to verify duty-status records. It identifies categories such as itineraries or schedules, dispatch and trip records, expense receipts, electronic mobile communication records, and payroll or settlement records.

  • Document or file type, issuing system, custodian, account, trip, shipment, load, unit, driver, and related identifier
  • Displayed date and time, timezone or location basis, creation time, transaction time, transmission time, revision time, and retrieval time when separately available
  • Physical location, GPS point, facility, merchant, toll plaza, fuel stop, delivery point, or other place stated by the source
  • Original record retained while extracted timestamps and normalized working copies are linked back to the source

Normalize time without erasing the original

  • Keep the displayed time and timezone exactly as shown before creating a second normalized time column
  • Record daylight-saving treatment, device offset, server time, terminal time, local time, and any unknown timezone as explicit fields
  • Distinguish creation, transmission, processing, settlement, and event times instead of treating every timestamp as the activity time
  • Document every conversion rule and preserve uncertain or conflicting times as unresolved rather than forcing alignment

Reconcile events row by row

  • Place the duty-status interval beside each potentially related trip, dispatch, location, fuel, toll, gate, cargo, communication, and payment event
  • Mark consistent, inconsistent, outside interval, ambiguous, or source missing without changing the underlying record
  • Record edits, annotations, certification times, device diagnostics, connection changes, unidentified-driving events, and reassignment history separately
  • List the next source or qualified review needed to examine each mismatch instead of converting it directly into a legal or safety conclusion

FMCSA’s current Hours of Service page summarizes federal driving, on-duty, break, sleeper-berth, and exception concepts and links current materials. A timeline should identify the regulation and version actually being examined; it should not apply a general summary to a trip without checking scope and exceptions.

Keep the reconciliation distinct from a fatigue opinion

A timestamp conflict may result from data entry, synchronization, timezone, transaction delay, reassignment, missing records, or other facts that require investigation. Conversely, aligned timestamps do not establish that every relevant event was recorded. Preserve the source set, methods, assumptions, gaps, and competing explanations for qualified review.

The related guide to electronic logging device records after a truck crash explains the device-specific events, edits, annotations, diagnostics, and export fields that may appear in the duty-status source. This page focuses on comparing that source with other records.
