How Do You Manage Fleet Compliance with ELDs?
Last Updated: October 29, 2026
Quick Summary
Fleet compliance with electronic logging devices means confirming which vehicles and drivers are covered, training drivers to log duty status correctly, and reviewing logs every day instead of waiting for an audit. Carriers also need a written malfunction procedure and monthly KPIs to prove the process works.

Why Electronic Logging Devices Demand a Fleet-Wide Compliance Process
Managing fleet compliance with electronic logging devices is no longer a side task for dispatchers.
Electronic logging devices (ELDs) connect to a truck's engine and record driving time. Under federal rules, most commercial motor vehicle operators must use one to track hours of service.
One driver using an ELD correctly does not make a fleet compliant.
Here is what that process has to cover:
Confirming which vehicles and drivers fall under the mandate
Training drivers on how the device works and how to log duty status
Reviewing data every day instead of waiting for an audit
Each of these steps supports the others. We break them down below in order.
Step 1: Confirm Your ELD Compliance Requirements Before Rollout
Confirm what your fleet must do before you buy anything. Not every vehicle or operation has the same obligations, and carriers who skip this step often buy the wrong device or miss an exemption.
Find out which trucks are commercial motor vehicles and whether your drivers fall under hours-of-service rules. Confirm which operations qualify for any exemption, and document the reason.
Checking FMCSA Registration and Technical Specifications
Before you choose a device, check that it appears on the FMCSA's list of registered ELDs. A device that is not registered does not meet federal requirements, no matter what the vendor claims.
Devices must connect to the engine, record required data such as date, time, location, and engine hours, and produce output that roadside inspectors can review.
Confirm the device is on the FMCSA registered list
Verify it connects to your engine model types
Check that it can produce the required output for roadside inspections
Recording Hours of Service and Records of Duty Status
Hours-of-service rules require a record of duty status (RODS) for each driver. The ELD captures driving time, but drivers still must mark on-duty, off-duty, and sleeper berth periods correctly.
A common mistake is assuming the device fills in everything. Properly reconciling these logs is essential for maintaining operational oversight, especially when unexpected vehicle breakdowns necessitate the immediate coordination of heavy duty towing services.
Step 2: Train Drivers to Use ELDs Correctly
Training is where most fleets win or lose. Drivers who understand the device make fewer logging errors and edits; drivers who do not create problems you only see later.
Cover these points in every training session:
How to log in and select the correct vehicle
How to change duty status during breaks, fuel stops, and loading time
What to do when the device shows a malfunction
Keep training short and hands-on. Drivers learn faster when they practice a real duty status change in front of a trainer.
Watch out: Drivers who share login credentials create records that are hard to defend. Require each driver to use a personal login.
Step 3: Set Up Daily ELD Data Monitoring
Do not wait for an audit to find out what your logs look like. Set up a daily review routine so problems surface while they are still small.
Powerfleet (formerly Fleet Complete)
Assign one person to check the previous day's logs each morning, flagging missing duty statuses, unusual driving hours, and device alerts. A short daily check beats a large cleanup at month's end.
Reviewing Log Edits and Unassigned Driving Time
Log edits and unassigned driving time are the two items to watch most closely. A high number of edits can signal a training gap or a driver hiding something; unassigned driving time shows driving never tied to a specific driver.
Review each edit and ask who made it, why, and whether other records such as fuel receipts or bills of lading support the change. Assign any unassigned time to the correct driver as soon as you can confirm it.
Step 4: Build a Procedure for ELD Malfunctions and Exceptions
Devices fail. Batteries die, cables loosen, and software glitches happen. The rules expect carriers to have a written plan for these events and to follow it. This is where most fleets are thinnest: competitors explain what an ELD is, but few show what to do when one misbehaves at 5 a.m. two states from the terminal.
Know the Four Malfunction Types
An ELD does not simply "stop working." It reports specific malfunctions, and each one triggers a different response. Train dispatchers and drivers to recognize these categories:
Power compliance malfunction, the device is not receiving power for a cumulative 30 minutes or more in a 24-hour period. Usually a loose cable, blown fuse, or failed connection.
Engine synchronization compliance malfunction, the ELD has lost its connection to the engine ECM (or to multiple ECMs) for more than 30 minutes in a 24-hour period. The device can no longer capture engine power status, vehicle motion, miles, or engine hours reliably.
Timing compliance malfunction, the device cannot cross-check its internal clock against a reliable external UTC source, so recorded times may drift.
When any of these fire, the device must alert the driver with a visual and audible warning. The driver acknowledges it, and the event is written into the record. A malfunction differs from a diagnostic event: diagnostics flag a potential issue (for example, a missing driver login), while malfunctions mean the device can no longer meet a technical requirement.
The Written Malfunction Procedure
Your procedure should be short enough to follow under pressure and specific enough to defend in an audit. A workable sequence:
Driver acknowledges and records. The driver notes the malfunction, the time it started, and the current location. The ELD captures this automatically, but the driver should also note it on paper in case the device fails entirely.
Driver reconstructs the record. For the affected period, the driver keeps paper records of duty status (RODS), or uses the ELD's manual-entry mode if the device still records, and carries them for the rest of the day and the following days until the device is repaired or replaced.
Carrier is notified the same day. Dispatch logs the report, opens a repair ticket, and notes the driver's location so a replacement or service call can be arranged.
Repair or replace within 8 days. Under the federal rules, a malfunctioning ELD must be repaired or replaced within 8 days of the malfunction being discovered. If the device cannot be fixed in that window, the carrier must keep the driver on paper logs and document why.
Restore and reconcile. Once the device is working, review the paper records against the ELD data, resolve any gaps, and file the reconstruction notes with the driver's record.
Watch Out Do not let a driver keep running on a malfunctioning device because "it still mostly works." A device that cannot synchronize with the engine or hold a GPS fix is not compliant, and the paper-log fallback is what protects the carrier during an inspection.
Handling Unassigned Driving Time
Unassigned driving time is the most common exception dispatchers face. It appears when the vehicle moves but no driver is logged in, a yard move, a mechanic's test drive, or a driver who forgot to log in. The ELD prompts the next driver who logs into that vehicle to accept or reject the unidentified driving.
A clean process looks like this:
Review unassigned driving events daily, not monthly.
Match the event to a driver using dispatch records, fuel receipts, bills of lading, or gate logs.
Ask the driver to accept the time if it is theirs; if it is not, annotate why and reassign it.
Handling Log Edits and Annotations
Drivers and carriers can propose edits, but the original record is never erased, the ELD keeps the original and the proposed change side by side, and the driver must approve or reject proposed edits. Require an annotation for every edit explaining who made it, when, and why. A pattern of edits on the same driver's log is a training signal, not just a paperwork nuisance.
Data-Transfer Failures at Roadside
If an inspector cannot pull data electronically, the driver must still be able to produce the record. Make sure every driver knows how to:
Display the ELD on the device screen for a visual check.
Send the output file by email or transfer it via the device's local connection.
Produce the printed or electronic RODS for the requested period.
Test the transfer method during onboarding, not during an inspection. A device that passes its automatic transfer test in the yard can still fail at a scale house on a weak signal.
Exemptions and Special Situations
Short-haul operations, certain drive-away/tow-away moves, and older vehicles may fall outside the mandate, but the exemption has conditions, time and distance limits, and in some cases a requirement to keep time records.
Keep a copy of the malfunction procedure in each truck and in the office, and review it at every quarterly safety meeting.
The four malfunction types and their triggers are easy to mix up, so the table below sets them out side by side.
Malfunction | Trigger | Likely cause |
Power compliance | No power for 30+ minutes in 24 hours | Loose cable, blown fuse |
Engine synchronization | Lost ECM connection for 30+ minutes in 24 hours | Broken engine connection |
Timing compliance | Clock cannot be cross-checked to UTC | Clock drift |
Positioning compliance | No valid GPS fix within 5 miles of movement | Missing or stale location data |
Data recording compliance | Cannot record or retain required events | Storage full or failure |
Data transfer compliance | Failed automatic transfer test three times in a row | Cannot deliver data to inspector |
Step 5: Audit Compliance With Measurable KPIs and Data Governance
A compliance program needs numbers. "We review the logs" is a habit, not a program. Pick a small set of key performance indicators (KPIs), set a target for each, and review them on a fixed cadence. This is the section most ELD explainers skip, and it is where a fleet actually proves compliance rather than asserting it.
The Core Compliance KPIs
You do not need a dashboard with fifty metrics. Six well-chosen measures will surface almost every problem before an inspector does:
HOS violation rate, violations per 100 driver-days, broken out by type (driving over the limit, missing a break, form-and-manner errors). Track the trend, not just the monthly count.
Unresolved log edits, edits awaiting driver approval or missing an annotation. Target: zero at the end of each week.
Unassigned driving events, count and total minutes per week. A rising count usually means a login or yard-move process is broken.
Set targets with your safety lead rather than copying industry averages. A target only works if the people reviewing it believe it is achievable and know what to do when it is missed.
A Monthly Audit Checklist
Run this on the same day each month so the numbers are comparable:
Pull the HOS violation report and compare it to last month's trend
Confirm every log edit has an annotation and driver approval
Assign or resolve all unassigned driving time and miles
Pro Tip Keep the completed checklist and the underlying reports. An audit trail of your own reviews is powerful evidence that the carrier has a functioning compliance process, not just compliant-looking logs.
Data Governance: Access, Retention, and Accuracy
ELD records contain driver identity, location history, and hours worked, treat them as sensitive operational data, not just compliance paperwork.
Access controls. Limit who can view and edit logs to the people who need it: dispatchers for assignment, safety staff for audit, and no one else by default.
Retention. The federal rules require carriers to retain ELD records for six months, and supporting documents for the same period. Set a retention policy that meets the minimum, then decide how long you keep data beyond that for internal analysis, and make sure the vendor's retention matches your policy, not the other way around.
Accuracy. The original record must never be overwritten. Edits are proposed, annotated, and approved, with the original preserved alongside.
Turning KPIs Into Action
Numbers only help if they change behavior. Set a simple rule: any KPI that misses its target for two consecutive months triggers a root-cause review, retraining for the drivers involved, a process change for dispatch, or a vendor conversation if the issue is device-side. Document the review and the fix. That record turns a compliance program from a monthly report into a repeatable system.

Frequently Asked Questions
What does an electronic logging device record?
An electronic logging device connects to a commercial motor vehicle's engine and automatically records driving time, engine hours, vehicle location, date and time, odometer readings, and the driver's duty status. This data builds the record of duty status that the FMCSA requires for hours of service compliance. Drivers can add annotations or make edits, but those changes are logged and can be reviewed. Fleet managers should confirm the device captures the required fields and that records can be produced during a roadside inspection.
How can fleet managers monitor ELD compliance?
Fleet managers can monitor ELD compliance by reviewing driver logs daily or weekly, flagging hours of service violations, and tracking log edits and unassigned driving time. Many fleets set real-time alerts for approaching hour limits and schedule a recurring audit of records against supporting documents such as fuel receipts and dispatch records. Tracking a small set of KPIs, like violations per 1,000 miles and percentage of logs certified on time, shows whether the program is working.
What should a driver do if an ELD malfunctions?
When an ELD malfunctions, the driver must notify the motor carrier within 24 hours and contact the ELD provider for a fix. The driver must also keep paper logs or use another method to record duty status until the device is repaired or replaced. Once the malfunction is resolved, the carrier should review the affected records and retain documentation of the malfunction and the corrective action taken.
How long must motor carriers retain ELD records?
Under FMCSA rules, motor carriers must retain records of duty status and supporting documents for six months from the date of receipt. Carriers should also keep copies of driver certifications, ELD malfunction reports, and log edit histories for the same period. Many fleets store records longer for internal audits and litigation readiness, and they should confirm their retention policy with legal counsel.
