Most drivers who must keep RODS must use an ELD unless a specific exception applies. Evaluate the exact driver, vehicle, trip, commerce, jurisdiction, and day; verify the precise exception text and keep supporting records. FMCSA's ELD list contains manufacturer-self-certified devices and is not an agency endorsement.
Mandate in four questions
- Must the driver keep RODS? Decide from the current rule and the exact operation.
- Does an ELD exception apply? Test every condition and keep supporting evidence.
- Is the installed ELD the exact active registered combination? Match name, hardware, software, ID, and status.
- Are records accurate? Registration does not replace correct login, duty status, edits, certification, unidentified-driving review, supporting documents, or retention.
The official list is manufacturer self-certification, not FMCSA endorsement. A listed device cannot guarantee a carrier’s compliance.
What to check
| Check | How to verify |
|---|---|
| 1. Determine whether the driver must prepare RODS | Keep the driver, vehicle, trip, commerce, jurisdiction, current RODS provision, qualified reviewer, and dated decision. |
| 2. Test every claimed ELD exception for the day | Retain every condition tested, underlying time or vehicle records, the exact exception provision, result, reviewer, and change trigger. |
| 3. Verify the exact registered ELD and version | Save the dated official-list match for device name, hardware, software, registration ID, and status. |
| 4. Complete required driver and carrier workflows | Keep completed login, duty-status, edit, unidentified-driving, certification, transfer, malfunction, and administrator-review tasks with defects and retests. |
| 5. Retain RODS supporting documents and review evidence | Retain the named record set, supporting-document associations, retention dates, access roles, retrieval test, reviewer, and exceptions. |
