ELD Compliance: What It Is, FMCSA Rules, and How to Comply
ELD compliance means using an FMCSA‑registered electronic logging device the right way to automatically capture a driver’s hours of service. In plain terms: if your vehicles require a record of duty status, you must install a compliant ELD, keep accurate logs, carry the correct in‑cab materials, and be able to show or transfer data to enforcement on request. It’s how fleets stay aligned with 49 CFR Part 395, prevent fatigue violations, and avoid costly out‑of‑service orders and fines.
This guide breaks down the rule in practical steps: who needs an ELD (and who doesn’t), the HOS limits an ELD enforces, device and system requirements, required documents and data transfer methods, how to handle unassigned driving and personal conveyance, editing and certification rules, what to do during malfunctions, record retention, and enforcement realities. You’ll also get a simple compliance checklist and tips for choosing a registered device—and for pairing ELDs with fleet GPS/telematics.
What the ELD rule covers at a glance
At a glance, the FMCSA’s ELD rule under 49 CFR Part 395 standardizes HOS logging for most drivers who must keep RODS. It defines what compliant devices must do, how data is handled and shared, and the rules drivers and inspectors follow to maintain ELD compliance.
- Engine‑synced logging: automatic capture of driving time and required data.
- Registered devices: self‑certified units listed on the FMCSA ELD registry.
- Data transfer: web services/email or local USB/Bluetooth to enforcement.
- Driver workflows: logins, duty statuses; Personal Use/Yard Move if enabled.
- Edits and integrity: edits need annotations, originals kept; malfunctions flagged.
Who needs an ELD (and who is exempt)
If a driver must keep a record of duty status (RODS) under 49 CFR Part 395, they generally need an FMCSA‑registered ELD. In practice, this captures most interstate commercial motor vehicle (CMV) operations. Typical triggers include operating CMVs 10,001 pounds or more, hauling placarded hazardous materials, or running passenger operations that require RODS. Also, if a driver uses paper logs more than eight days in any rolling 30‑day period, ELD compliance applies.
-
Who needs an ELD:
- Drivers required to keep RODS in interstate commerce.
- CMVs ≥10,001 lbs GVW/GVWR, when RODS are required.
- Placarded hazmat operations that require RODS.
- Paper logs >8 days in 30 days (short‑haul exceeded).
-
Who is exempt:
- Drivers not required to keep RODS (e.g., eligible short‑haul who exceed RODS no more than 8 days/30).
- Driveaway–towaway operations where the vehicle driven is the commodity.
- Vehicles with engines pre‑model year 2000.
When in doubt, determine if the route and vehicle require RODS; if yes and no exemption applies, an ELD is required.
HOS basics every driver must follow with an ELD
ELD compliance doesn’t change the Hours of Service limits; it changes how you record them. Under 49 CFR Part 395, drivers must maintain accurate records of duty status from report time through end of shift, take required off‑duty rest (10 consecutive hours before driving again), and be able to display or transfer logs during inspections. The ELD automatically captures driving time and key data, but the driver is responsible for correct statuses and daily certification.
In practice, that means building consistent habits that keep HOS clean and defensible on the road and in audits.
- Set the right duty status: Driving is auto‑recorded; select On Duty, Off Duty, or Sleeper as activities change.
- Annotate when needed: Add brief notes to explain corrections or unusual situations.
- Certify each day’s log: Review and certify records at the end of every 24‑hour period.
- Take authorized special driving only when allowed: Use Personal Conveyance or Yard Move only if your carrier enables it.
- Resolve unassigned driving: Review, accept, or reject unassigned time before certifying to keep records accurate.
ELD device and system requirements (what makes an ELD compliant)
An ELD is compliant only if it’s on the FMCSA’s registered list and meets the technical specs in 49 CFR Part 395. Registration is self‑certified by the manufacturer, and listings can be revoked—so carriers must verify devices and keep them installed and used per the rule.
- Engine synchronization: Connects to the engine to automatically record driving time and motion status.
- Automatic data capture: Logs date, time, location, engine power status, engine hours, vehicle miles, and motion; associates records to the driver/vehicle.
- Driver accounts and statuses: Supports secure login and selection of duty statuses (with carrier‑enabled Personal Conveyance/Yard Move).
- Edits with audit trail: Allows annotated edits by driver/carrier while preserving originals; driving time cannot be edited.
- Tamper resistance: Protects records against alteration and flags inconsistencies.
- Malfunction detection: Monitors and alerts for malfunctions and data diagnostic events.
- Data transfer to enforcement: Provides secure transfer via telematics (web services/email) or local (USB/Bluetooth) to eRODS.
- On‑demand display: Presents a HOS graph grid and required RODS details for inspection outside the vehicle if needed.
- Unassigned driving handling: Identifies unassigned time so carriers/drivers can review and assign or reject it.
Required in-cab documents and data transfer methods
Roadside inspections hinge on two things: having the right materials at hand and being able to share logs on demand. Under FMCSA’s ELD rule, compliant devices must transfer data to enforcement via telematics (web services/email) or locally (USB/Bluetooth), and they must present a clear RODS/graph-grid view that officials can see without entering the vehicle.
- ELD user manual: Keep the device’s user manual accessible in the cab (paper or electronic) so drivers can follow the correct steps.
- Data transfer readiness: Drivers must know how to send logs using the device’s approved method(s): web services/email or USB/Bluetooth to eRODS.
- On‑screen HOS display: Have the graph grid and required RODS details ready to show as a backup to electronic transfer.
- Quick reference: Keep provider-supplied inspection tips/cheat sheets handy to speed up interactions and reduce errors.
Unassigned driving, personal conveyance, and yard moves
These are common trouble spots for ELD compliance. Unassigned driving happens when the vehicle moves without a logged‑in driver; Personal Conveyance (PC) and Yard Move (YM) are special categories that can be used only if your carrier enables them. A compliant ELD flags unassigned time and tags authorized PC/YM movements so your RODS stay accurate and defensible at inspection.
- Unassigned driving: At login/logout, review and assign or reject any unassigned driving with a short annotation. Carriers should reconcile leftovers in the back office. Prevent it by ensuring the correct driver is logged in before the truck moves.
- Personal conveyance (PC): Use only for off‑duty personal use when your carrier permits it. Select PC before moving; the ELD will record the event and flag it as PC. Add a brief note and exit PC when finished.
- Yard moves (YM): Use for movements within yards/terminals when authorized. Select YM before moving; the ELD records the event with a YM flag. Annotate as needed and clear YM before returning to public roads.
Editing logs, annotations, and certification rules
ELD compliance allows limited corrections to fix mistakes while preserving data integrity. Drivers and authorized carrier staff may edit non‑driving records and add annotations; the original record is always retained. Driving time recorded by the engine‑synced ELD cannot be changed. Every change must include a clear note, and the driver has the final approval and must re‑certify the day’s logs.
- Fix status errors fast: Correct Off Duty, On Duty, or Sleeper mistakes and add missing remarks.
- Annotate every change: Include a brief reason for each edit or assignment, including unassigned driving time.
- Driver has final say: Carrier staff can propose edits, but they apply only after driver approval.
- Re‑certify daily: Certify each 24‑hour period—and re‑certify after any edits—to keep logs valid.
Malfunctions and roadside contingencies (what to do if the ELD fails)
Even compliant ELDs can trigger data diagnostics or malfunction events. When that happens, the driver still has to remain ELD compliant by keeping accurate HOS, being inspection‑ready, and following the device’s and carrier’s procedures to resolve the issue quickly.
- Recognize and annotate: If the ELD flags a malfunction/diagnostic, add a brief note in the log describing what happened.
- Notify the carrier promptly: Report the issue and follow your company’s repair/replacement process.
- Use paper RODS temporarily: Reconstruct the current day and up to the previous 7 days (if records aren’t available) on paper log sheets and keep them in the cab.
- Be inspection‑ready: If data transfer fails, use the ELD’s on‑screen HOS graph grid as backup and provide your paper logs to enforcement.
- Try alternate transfer methods: If the primary telematics/local method fails, attempt the other method supported by your device.
- Resolve and reconcile: After the fix, ensure electronic records are complete, address any unassigned driving, and re‑certify affected days.
Record retention and supporting documents requirements
ELD compliance doesn’t end at the dash. Carriers must keep RODS and related ELD data in a way that’s organized, secure, and readily available for inspections or audits under 49 CFR Part 395. The ELD rule also preserves data integrity, so your files should reflect both original and edited records, plus the annotations and certifications that explain changes.
- Keep core ELD records: Daily RODS, graph grids, edit/audit trails, driver certifications, unassigned driving reports, and malfunction/diagnostic notices with resolutions.
- Retain transfer evidence: Copies/screenshots of successful eRODS data transfers and any inspector‑provided documentation.
- Maintain supporting documents: Operational papers that corroborate duty status (e.g., bills of lading/dispatch records, fuel and toll receipts, shipment and payroll/settlement records).
- Standardize submissions: Define how and when drivers submit documents, how back office reconciles discrepancies, and how records are backed up and access‑controlled.
ELD compliance checklist for fleets and drivers
Use this quick, repeatable checklist to keep ELD compliance tight on the road and defensible during inspections and audits. Build it into driver onboarding, daily routines, and your back‑office review cadence.
-
Drivers — before/during each trip:
- Log in before moving; set the correct duty status.
- Review unassigned driving at login/logout; assign or reject with an annotation.
- Use PC/YM only if authorized; select it before moving and exit when done.
- Annotate corrections and certify logs daily; re‑certify after any edits.
- Carry the user manual and know how to transfer data (web services/email or USB/Bluetooth); practice a test send.
- If the ELD malfunctions: note it, notify the carrier, use paper RODS, and be inspection‑ready with the on‑screen grid.
-
Fleets — ongoing controls:
- Verify devices are on the FMCSA registry (and not revoked); recheck periodically.
- Set written PC/YM policies, create driver accounts, and train on use and inspections.
- Monitor unassigned driving, edits, and malfunctions; resolve and reconcile quickly.
- Audit HOS weekly and retain RODS, edit trails, transfers, and supporting documents in an organized system.
How to choose an FMCSA-registered ELD (and avoid revoked devices)
Choosing an FMCSA‑registered ELD is both a compliance and operations decision. Because registration is manufacturer self‑certification and devices can be removed from the list, you need a repeatable vetting process to avoid revoked units and select a solution your drivers can actually use.
- Verify FMCSA listing and status: Confirm the model is on the registry and not revoked; recheck periodically.
- Match data transfer methods: Ensure it supports your preferred telematics (web services/email) or local (USB/Bluetooth) options used at inspections.
- Confirm engine sync and required data: Date/time, location, engine power status, engine hours, miles, and motion per Part 395.
- Evaluate driver workflows: Secure login, clear duty statuses, robust handling of unassigned driving, and carrier‑controlled PC/YM.
- Check edit/certification controls: Immutable originals, required annotations, driver approval, and daily certification.
- Assess malfunction handling: Built‑in diagnostics, clear alerts, fallback procedures, and an in‑cab HOS display/manual.
- Decide hardware approach: Hard‑wired/tethered vs. BYOD/Bluetooth; consider connectivity reliability and ease of use.
- Weigh support and training: Accessible onboarding, inspection how‑to guides, and responsive customer service.
- Look for independent validation: Optional third‑party testing can add confidence beyond self‑certification.
- Plan integrations/reporting: Compatibility with your telematics and back‑office systems to streamline compliance reviews.
Enforcement, audits, and penalties for non-compliance
ELD compliance is enforced at roadside inspections and during FMCSA investigations. Since hard enforcement began in 2018 and full compliance in 2019, inspectors expect drivers to display or transfer logs on request. If a device isn’t on the FMCSA registry (or has been revoked), or a driver can’t show/transfer data, they may be cited for “no record of duty status” and placed out of service under CVSA criteria. Carriers and drivers can face civil penalties of roughly $1,000–$10,000 per offense (Title 49, section 521).
-
Common triggers:
- Using non‑registered/revoked ELDs: Treated as non‑compliance.
- Failure to transfer or display logs: Can lead to NRDS and out‑of‑service.
- Missing in‑cab materials: Citations and inspection delays.
- Unassigned driving not reconciled: Violations and follow‑up inquiries.
- Improper edits/falsification: Penalties and potential audits.
-
Carrier exposure: Citations, out‑of‑service orders, increased scrutiny, and reputational risk escalate with repeated deficiencies.
How ELDs work with fleet GPS tracking and telematics
An ELD is the compliance engine for HOS, while telematics and GPS tracking turn that compliance data into day‑to‑day operational insight. Because ELDs already sync with the engine and capture time, location, miles, and motion, integrating them with a fleet tracking platform creates one view for dispatch, safety, and maintenance to act on in real time.
- One source of truth: Align ELD HOS with GPS trips to reconcile unassigned driving.
- Smarter dispatch: See driver availability, closest‑to‑job vehicles, and live ETAs.
- Safety insights: Use driver‑behavior alerts (e.g., harsh events) to coach and reduce risk.
- Maintenance: Leverage engine hours/miles and fault data to schedule service.
- Compliance reporting: Streamline DVIR workflows and IFTA mileage by jurisdiction.
- Customer service: Geofenced arrival/departure stamps verify stop times and detention.
Key takeaways
ELD compliance means using a registered device correctly, following HOS, carrying required materials, sending data on request, managing unassigned time and PC/YM, editing with annotations and daily certification, handling malfunctions with paper logs, and retaining records. Nail these basics and inspections run smoothly.
- Confirm registration: Verify your ELD is listed—not revoked.
- Train and practice: Teach drivers and rehearse data transfers.
- Control PC/YM: Enforce policy and reconcile unassigned time.
- Audit weekly: Review logs; document edits and notes.
- Have a fallback: Keep malfunction playbooks and paper logs.
