FMCSA published the ELD final rule in 2015; the grandfathered AOBRD transition ended in December 2019. Today, fleets subject to the rule should use an active, manufacturer-self-certified ELD listed by exact device and software version. Treat predictive maintenance and automated tax reporting as optional product features that require current evidence, not as part of the ELD rule.
From paper RODS to current ELDs
- Paper records: drivers recorded duty status manually; carriers retained and reviewed RODS and supporting evidence.
- Automatic on-board recorders: AOBRDs added electronic recording under an earlier technical framework but did not equal today’s ELD specification.
- 2015 final rule: FMCSA published the ELD and supporting-documents final rule, establishing minimum device performance, mandatory-use scope, supporting-document rules, and anti-harassment measures.
- Full ELD operating model: covered drivers use registered manufacturer-self-certified ELD combinations; automatically recorded vehicle data works with driver entries, carrier review, edits, transfer, malfunction procedures, and retention.
- Current fleet automation: dispatch, GPS, IFTA, maintenance, and analytics may connect to an ELD but remain optional product capabilities requiring separate evidence and governance.
What to check
| Check | How to verify |
|---|---|
| 1. Build the timeline from primary rule sources | Keep each rulemaking or provision, publication and effective dates, exact milestone, source URL, and reviewer. |
| 2. Separate paper AOBRD and ELD requirements | Retain a comparison of record method, transition authority, effective period, required functions, and current status for each stage. |
| 3. Distinguish automated events from human decisions | Map automatic driving and vehicle events against driver-selected statuses, edits, annotations, unidentified-driving review, and certification. |
| 4. Verify today's registered-device technical baseline | Save current Part 395/appendix and official-list evidence for engine synchronization, event recording, display or transfer, hardware/software, ID, and status. |
| 5. Remove obsolete modes dates and applicability assumptions | Keep the obsolete statement, current authority, replacement wording, affected workflow, reviewer, correction date, and future recheck trigger. |
