10 Most Common ELD Violations and How to Avoid Them

ELD violations are one of the top categories of citations during DOT roadside inspections. In 2024, FMCSA reported over 200,000 HOS-related violations during roadside inspections — many directly tied to ELD non-compliance. Each violation can result in out-of-service orders, fines up to $16,000, and lasting damage to your CSA safety scores.

The good news: most ELD violations are preventable with proper driver training, device maintenance, and compliance processes. This guide covers the 10 most common ELD violations, explains what inspectors look for, and provides specific steps to avoid each one.

How ELD Enforcement Works

ELD compliance is checked in two main ways: roadside inspections and DOT compliance audits. During a Level I or Level III roadside inspection, an inspector will ask to see the driver's ELD, review the current day's logs and the previous 7 days, and may request an electronic data transfer. During an audit, FMCSA reviews the carrier's ELD records, unassigned driving reports, and overall HOS compliance.

Violations are recorded in the FMCSA Safety Measurement System and affect the carrier's CSA scores under the HOS Compliance BASIC. High violation rates can trigger intervention — warning letters, targeted inspections, or compliance reviews.

The 10 Most Common ELD Violations

1. No ELD When Required

The most straightforward violation: a driver is required to use an ELD but does not have one. This results in an immediate out-of-service order — the driver cannot continue operating until the situation is corrected.

Common causes:

• Driver or carrier incorrectly believes they qualify for an ELD exemption
• ELD was removed or not reinstalled after vehicle maintenance
• New driver was not provided an ELD before dispatching

How to prevent it: Verify every driver's ELD exemption status before dispatching. If a driver does not qualify for an exemption, an ELD must be installed and operational before the truck moves. Include ELD verification in your pre-dispatch checklist.

2. ELD Not Registered with FMCSA

Using a device that is not on the FMCSA Registered ELD List is treated the same as not having an ELD. FMCSA periodically removes devices that fail to meet technical specifications.

How to prevent it: Before purchasing any ELD, verify it is on the current registered list. Check the list quarterly to ensure your devices have not been removed. If your ELD provider is delisted, you must switch to a registered device immediately.

3. Unassigned Driving Time

When a vehicle moves with no driver logged into the ELD, the device records "unassigned driving time." Carriers must review and assign this time to the correct driver. Excessive unassigned driving time is a red flag — it may suggest drivers are logging out to avoid recording driving time.

How to prevent it: Train drivers to log in before starting the vehicle. Review unassigned driving reports daily or weekly. Assign all unassigned time promptly. Set up alerts in your ELD system to flag unassigned driving events.

4. ELD Malfunction Not Documented

When an ELD malfunctions, the driver must note the malfunction, switch to paper logs, and notify the carrier within 24 hours. The carrier then has 8 days to repair or replace the device. Failure to follow these procedures is a violation — even if the ELD genuinely malfunctioned.

How to prevent it: Train drivers on the malfunction procedure. Keep blank paper RODS in every cab. Create a simple process for drivers to report malfunctions (phone call, text, or app notification). Track malfunction reports and repair deadlines centrally.

5. Failure to Transfer ELD Data During Inspection

During a roadside inspection, the inspector may request an electronic data transfer via Bluetooth, USB, or email. If the ELD cannot transfer data, the driver receives a violation. Common causes: dead battery on the display device, Bluetooth turned off, email not configured, or the driver does not know how to initiate a transfer.

How to prevent it: Train every driver on all data transfer methods their ELD supports. Test the transfer function regularly. Ensure the display device (phone or tablet) is charged. Keep a USB cable accessible if the ELD supports USB transfer.

6. Form and Manner Violations

Form and manner violations mean the ELD log is missing required information. These are among the most common ELD citations because they are easy for inspectors to spot. Missing information includes:

• Driver's name or employee ID not entered
• Vehicle unit number missing or incorrect
• Carrier name incorrect
• Missing annotations for duty status edits
• 24-hour period not properly set (midnight to midnight)
• Co-driver information missing when team driving

How to prevent it: Verify that driver profiles in the ELD system have correct names, IDs, and carrier information. Train drivers to add annotations when editing duty status changes. Periodically audit driver logs for missing fields.

7. HOS Violations Detected via ELD Data

ELD data makes it much easier for inspectors to detect Hours of Service violations. Common HOS violations found through ELD review include:

• Exceeding the 11-hour driving limit
• Exceeding the 14-hour on-duty window
• Insufficient 10-hour off-duty rest between shifts
• Exceeding the 60/70-hour weekly limit
• Improper use of the 30-minute rest break exemption

How to prevent it: Use your ELD's HOS countdown timers and alerts. Train dispatchers to check drivers' remaining hours before assigning loads. Never pressure drivers to operate beyond their available hours.

8. Driver Not Trained on ELD Use

Under 49 CFR §395.22, carriers must ensure drivers are trained on ELD use before operating with the device. If a driver cannot demonstrate basic ELD competency during an inspection — cannot change duty status, add annotations, or initiate data transfer — the inspector may cite a training deficiency.

How to prevent it: Provide documented ELD training for every driver before their first trip. Include ELD operation in your new driver onboarding process. Keep training records accessible during audits.

9. Operating with a Prohibited Device

FMCSA prohibits devices or software designed to circumvent, disable, or modify ELD data recording. This includes "defeat devices" that disconnect the ELD from the engine, GPS spoofing tools, and software that allows editing of locked driving records. Using such devices is treated as ELD tampering.

How to prevent it: Establish a zero-tolerance policy for ELD circumvention devices. Inspect vehicles periodically for unauthorized hardware connected to the diagnostic port. Audit ELD data for suspicious patterns (e.g., sudden GPS location jumps, gaps in engine data).

10. ELD Tampering and Data Falsification

The most serious ELD violation. Tampering includes altering, deleting, or falsifying ELD records. This can result in driver disqualification, carrier fines up to $16,000 per violation, and criminal prosecution in severe cases.

How to prevent it: Create a clear written policy prohibiting ELD tampering. Train drivers that falsifying records is a terminable offense. Review driver logs for patterns that suggest manipulation (identical daily patterns, driving time that does not match GPS data). Report any tampering attempts to management immediately.

Penalties for ELD Violations

How ELD Violations Affect Your CSA Score

ELD and HOS violations are recorded under the HOS Compliance BASIC in the CSA Safety Measurement System. Each violation is assigned a severity weight (1-10) and a time weight (recent violations count more heavily). Your carrier's percentile is compared against peers with similar inspection volume.

The HOS Compliance BASIC intervention threshold is 65% for general carriers and 50% for passenger carriers. Exceeding the threshold can trigger:

• Warning letters from FMCSA
• Targeted roadside inspections — your trucks get pulled over more frequently
• Compliance investigation — an on-site FMCSA review of your operations
• Consent decree or operations shutdown in extreme cases

Frequently Asked Questions

What are the most common ELD violations?

The most common include: no ELD when required, unregistered devices, unassigned driving time, malfunction documentation failures, data transfer problems, form and manner errors (missing information in logs), HOS violations detected through ELD data, insufficient driver training, prohibited circumvention devices, and data tampering.

What is the penalty for ELD violations?

Penalties range from citations to out-of-service orders depending on severity. Operating without a required ELD results in an immediate out-of-service order. Fines can reach $16,000 per violation for carriers. All ELD violations affect your CSA safety scores under the HOS Compliance BASIC.

What happens if I have unassigned driving time on my ELD?

Unassigned driving time must be reviewed and assigned to the correct driver within 13 days. During DOT audits, unresolved unassigned driving is a violation. Excessive unassigned driving suggests potential HOS circumvention and will draw additional scrutiny from auditors.

How do ELD violations affect my CSA score?

ELD violations fall under the HOS Compliance BASIC. Each violation is weighted by severity (1-10 points) and recency. Accumulating violations can push your carrier above the intervention threshold (65% for general carriers), triggering FMCSA warning letters, targeted inspections, or compliance investigations.

What is an ELD form and manner violation?

Form and manner violations mean the ELD log is missing required information: driver's name, vehicle unit number, carrier name, annotations for edits, or other required header data. These are among the most common citations because they are easy to detect and often result from incomplete driver profiles or lack of training.

Can I get an out-of-service order for ELD violations?

Yes. Operating without a required ELD, using an unregistered device, or being unable to present RODS for the current day and previous 7 days results in an out-of-service order. The driver cannot continue operating until the violation is corrected.

What should I do if my ELD malfunctions on the road?

Note the malfunction, begin keeping paper RODS immediately, and notify your carrier within 24 hours. The carrier has 8 days to repair or replace the ELD. Keep paper logs and malfunction documentation available for any roadside inspection during the malfunction period.

Is ELD tampering a criminal offense?

ELD tampering can result in driver disqualification, fines up to $16,000 per violation, and criminal prosecution in severe cases. Carriers that knowingly allow tampering face additional penalties including potential shutdown orders. FMCSA has made ELD enforcement a priority in recent years.

Stay Violation-Free with Proper ELD Management

Most ELD violations are preventable. The key is a combination of driver training, proactive device maintenance, and regular compliance auditing. Understanding FMCSA ELD rules and building compliance processes around them protects your drivers, your CSA scores, and your bottom line.
