FMCSA identifies five supporting-document categories and requires motor carriers to retain RODS and applicable supporting documents for six months. Fleets need a consistent collection, association, and retrieval workflow.
What this means for your fleet
Map each document category to its source system, driver or vehicle identifier, date, retention owner, and retrieval method. Test an audit request across dispatch, expense, payroll, and communication systems.
The five FMCSA document categories
- Bills of lading, itineraries, schedules, or equivalent trip-origin and destination records.
- Dispatch records, trip records, or equivalents.
- Expense receipts tied to on-duty-not-driving time.
- Electronic mobile communications through a fleet-management system.
- Payroll records, settlement sheets, or equivalent pay records.
Motor carriers must retain RODS and applicable supporting documents for six months. When more than eight supporting documents exist for a 24-hour period, apply the detailed earliest/latest and six-additional-document rule in 49 CFR 395.11 rather than deleting records by guesswork.
What to check
| Check | How to verify |
|---|---|
| 1. Identify the five document categories | Keep the current source naming each of the five categories and map every category to the fleet's source system and retention owner. |
| 2. Capture driver and date association | Retain the original document with driver or vehicle identifier, date, source-system timestamp, association rule, exception, and reviewer. |
| 3. Retain original timestamps | Save source-system and received timestamps, original file or transaction ID, time zone, later correction history, and preservation hash. |
| 4. Apply quantity rules under 49 CFR 395.11 | Cite 49 CFR 395.11 and retain the day, driver, available documents, quantity calculation, selected set, exception, and qualified review. |
| 5. Test retrieval with an ELD day | Retrieve one ELD day and each applicable category by driver, vehicle and date; keep timing, counts, missing items, owner, and remediation. |
Common failure modes
- Saving documents without driver linkage.
- Assuming the ELD export contains every supporting record.
- Editing timestamps to align systems.
Limits and exceptions
Use this guide to plan your checks; it does not determine whether a legal exception applies, certify a record, or guarantee compliance, safety, savings, or audit results. Preserve original ELD records and edit history. Use the current rules to determine applicability and the manual for your installed device for operating instructions.

Discuss your ELD workflow
Ask Factor ELD to demonstrate the workflow on your installed system. Have the driver, vehicle, trip details, and original ELD record ready. A qualified compliance reviewer should determine how the current rules apply to the trip.
