What Role Does Electronic Logging Data Play In A Semi Truck Case?

Electronic logging devices (ELDs) record driving time, speed, braking activity, and truck location, allowing investigators to identify unsafe driver behavior and regulatory violations. This digital evidence also documents compliance with hours-of-service limits and required rest breaks, helping clarify whether fatigue or scheduling pressures contributed to the crash.

With the Best of Best Attorneys badge, the lawyers at Todd Miner Law obtain ELD data by sending spoliation letters to the trucking company. If the company refuses to provide the records, we use subpoenas to secure the evidence. Then, we consult forensic analysts to review the ELD data and verify its accuracy.

How Can ELD Data Help You Prove Fault in a Semi-Truck Accident Case?

ELD data helps establish liability by providing objective, time-stamped evidence of a truck driver’s activities leading up to the accident, including hours-of-service violations, speeding, or hard braking. For example, if ELD data shows the driver failed to take the required 10-hour rest period, that violation can prove negligence if fatigue contributed to the crash.

In addition, ELDs can reveal repeated violations or unrealistic schedules, which may indicate poor supervision or pressure to exceed legal limits. This evidence can extend liability beyond the driver and support claims against the motor carrier. For example, in a Rear-End Collision in Williamsburg, Virginia, involving a truck tractor, investigators held the motor carrier Triton Logistics accountable for creating false driver accounts in its electronic logging system. This practice allowed drivers to operate beyond federal hours-of-service limits, which increased crash risk due to fatigue.

How Do Attorneys Obtain and Preserve ELD Evidence After a Crash?

To preserve ELD data, attorneys send preservation letters to the motor carrier, the truck driver, and other responsible parties within 24 to 72 hours of the truck accident. If the trucking company does not cooperate, lawyers may seek a court order to prevent destruction or alteration of the data.

In some cases, they also subpoena the ELD service provider, especially when the company claims the information is unavailable. After obtaining the records, lawyers document how the ELD data was collected, stored, and reviewed to maintain the chain of custody.

How Long Do Trucking Companies Keep ELD Records?

Under 49 CFR § 395.8, trucking companies are required to maintain ELD records for at least six months. Federal regulations (49 CFR 395.22(i)) also require them to store a backup copy of the same data for 6 months. Other than that, carriers must preserve related supporting documents such as dispatch records, fuel receipts, and toll receipts for the same duration. After the six-month period expires, companies may legally discard the data unless litigation is pending.

What’s the Difference Between ELDs and Black Box Data Recorders?

ELDs track a truck driver’s hours to ensure compliance with federal hours-of-service safety rules. In contrast, black box data recorders capture technical information, such as speed, sudden acceleration, and braking patterns. While black box recorders are present in both passenger and commercial vehicles, ELDs are generally required only in commercial trucks under federal laws.

How Does Personal Conveyance in ELD Logs Impact Liability?

Personal conveyance entries in a truck’s ELD logs reveal whether the driver properly claimed off-duty status or improperly used that designation to extend driving time. If the driver performs work-related tasks while marking personal conveyance, the log may be considered falsified. That falsification can support a finding of negligence and strengthen liability against the driver and the motor carrier.

However, insurance companies often challenge these claims by arguing that the movement qualifies as permitted personal use. To support that position, they rely on driver statements, internal company policies, or incomplete supporting records, such as dispatch logs or trip sheets. In such situations, you shouldconsult our lawyers at Todd Miner Law.

Our founder, with 32 years of experience as an insurance defense attorney, counters these claims with a strategic approach. To prove improper driving logs, we compare personal conveyance entries with GPS data, dispatch instructions, and fuel receipts. Our legal team also reviews toll records and trip timelines to identify inconsistencies that show the driving was work-related. Contact us now for a free case review.

Can Trucking Companies Manipulate or “Edit” ELD Records?

Yes, trucking companies may edit ELD records under 49 CFR § 395.30. The law allows both the motor carrier and the truck driver to edit missing or inaccurate information. However, they cannot alter automatically recorded maximum driving hours or erase logged driving activity.

Furthermore, federal regulations also require transparency whenever a record is edited. This means the original entry must remain visible, and each modification should include an annotation explaining the reason for the edit. The driver must also review and either approve or reject any edits proposed by the motor carrier.

How Do Experts Validate Electronic Logging Data?

To validate electronic logging data, accident reconstruction experts perform a forensic analysis of the data and its metadata to determine whether the records are accurate and complete. They review edits and annotations, check for unidentified driving segments, and analyze system entries for irregular patterns that may indicate tampering or improper use. This validation process is especially important in cases involving blind spot accidents, where precise timing, lane positioning, and driver activity before impact can directly affect liability findings.

Here are some additional strategies experts use to validate ELD data:

• Compare ELD timestamps with witness accounts, bills of lading, dispatch records, and physical evidence from the accident scene, to confirm accuracy.
• Verify that the ELD properly synced with the vehicle’s engine control module to confirm actual driving time and engine hours.
• Generate digital hash values to confirm that the downloaded data was not altered after extraction.
• Examine GPS coordinates to ensure recorded locations align with documented routes and reported stops.

Does Yard Moves Status in ELD Data Affect Crash Liability?

Yes, yard moves status can affect crash liability in truck accident claims. Yard move status is intended only for low-speed movement within a terminal, warehouse lot, or shipping yard. When records show the truck traveling at roadway speeds or covering significant distances, investigators may conclude the driver used the status to avoid logging driving time. This misuse can indicate driver fatigue, log falsification, and hours-of-service violations, which can help prove liability.

What If The Driver Were Using An Exempt ELD Or Paper Logs?

If a driver used an exempt ELD or paper logbooks, lawyers for semi truck accident examine the driver’s eligibility for that exemption under federal regulations. For example, federal regulations allow paper logs for only 8 days within any 30-day period. After that, the driver must use an ELD. Similarly, commercial trucks manufactured after model year 2000 are not exempt and must comply with electronic logging requirements.

However, short-haul drivers operating within a 100- or 150-air-mile radius who meet specific time-reporting requirements may qualify for limited exceptions. Even then, drivers using paper logs must keep accurate records for the current 24-hour period and the previous 7 days.
