Federal hours-of-service rules limit how long commercial truck drivers can be behind the wheel. When those limits are exceeded, the resulting fatigue is a recognized cause of serious crashes on Georgia interstates and surface roads. In a Georgia civil case, proving that a driver or carrier violated hours-of-service rules is largely a question of evidence gathering, documentation, and disciplined preservation work. This guide explains the rules at issue and the categories of proof that courts and juries typically consider.
The rules at issue
The federal hours-of-service rules for property-carrying commercial drivers are set out in 49 C.F.R. Part 395, administered by the Federal Motor Carrier Safety Administration (FMCSA). For most drivers operating in interstate commerce, the core daily limits in 49 C.F.R. 395.3 include an 11-hour driving limit within a 14-hour on-duty window following 10 consecutive hours off duty, and a required 30-minute break after 8 cumulative hours of driving without an interruption. The weekly limit is generally 60 hours in 7 consecutive days, or 70 hours in 8 consecutive days for carriers that operate every day.
Since December 18, 2017, most drivers subject to hours-of-service requirements have been required to record their duty status using an electronic logging device (ELD) under 49 C.F.R. Part 395 Subpart B. The ELD captures driving time automatically through the truck’s engine control module, reducing the ability of drivers and carriers to manipulate paper logs.
Electronic logging device data
The single most important source of proof in a hours-of-service case is usually the ELD data itself. The device automatically records engine-on time, vehicle movement, miles driven, and driver duty status changes. ELD output can be compared against the on-duty cycle the driver claimed and against the time of the collision to show whether the driver was over the 11-hour driving cap, outside the 14-hour window, or skipping required breaks.
Because ELD data is electronic and overwritten on rolling schedules, prompt preservation is critical. A litigation hold or spoliation letter served on the carrier early in the case asks the company to preserve the device data, supporting documents, and back-end carrier records before they are deleted or overwritten in the ordinary course of business.
Supporting documents required by federal rule
The hours-of-service rules require carriers to keep supporting documents that corroborate or contradict the logs. Under 49 C.F.R. 395.11, carriers must retain up to eight supporting documents per driver per 24-hour period for six months. Categories of supporting documents include bills of lading, dispatch records, expense receipts, fleet management system communications, and payroll records. These can show where the truck actually was and when, and may reveal driving time the driver did not log.
Driver Vehicle Inspection Reports and trip documents
Driver Vehicle Inspection Reports (DVIRs), fuel receipts, toll records, and weigh station logs can all be matched against the duty-status entries. If a fuel receipt is time-stamped during a period the driver logged as off duty in a sleeper berth, the inconsistency itself becomes evidence of a violation.
Engine control module and telematics
Many trucks carry telematics systems beyond the ELD: GPS units, dashcams, and fleet management platforms produced by vendors such as Samsara, Geotab, or Omnitracs. These systems record speed, hard braking, location, and sometimes inward-facing video. Telematics data can confirm engine-on periods and document whether the driver was actually driving when the log says otherwise.
Carrier-side records
Hours-of-service cases often involve allegations that the carrier knew, or should have known, that the driver was over-hours. Relevant carrier records include dispatch logs, load assignments, internal messages between dispatchers and drivers, prior log audits, safety department violations files, and driver qualification files maintained under 49 C.F.R. Part 391. Federal Motor Carrier Safety Administration roadside inspection results and the carrier’s Safety Measurement System data, both available through the FMCSA portal, are additional public sources.
Third-party data
External records can corroborate or contradict log entries. Toll transponder data on Georgia’s Peach Pass system or on out-of-state systems shows the precise time the truck crossed each toll point. Surveillance video from truck stops, shippers, and receivers can place the truck at locations during claimed off-duty periods. Cell phone records and text messages exchanged with dispatch may show the driver was working during logged rest.
Expert testimony
Trucking-industry experts and hours-of-service specialists frequently review the assembled evidence to translate raw ELD data, supporting documents, and telematics output into a clear timeline. In Georgia, expert testimony is governed by O.C.G.A. 24-7-702, which incorporates the Daubert framework articulated by the United States Supreme Court in Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993). The expert must rely on sufficient facts or data, use reliable methods, and apply those methods reliably to the case.
Discovery practice
Hours-of-service violations are typically built up through interrogatories, requests for production, depositions of the driver and safety personnel, and Rule 30(b)(6) depositions of corporate representatives under O.C.G.A. 9-11-30. Requests for production typically seek ELD raw data files, supporting documents under 49 C.F.R. 395.11, driver qualification files, dispatch records, and carrier safety audit results.
Spoliation considerations
If carrier records are destroyed after a duty to preserve has attached, Georgia courts have authority to impose spoliation sanctions. Georgia treats spoliation under common-law principles articulated in cases such as Phillips v. Harmon, 297 Ga. 386 (2015), where remedies can include adverse inference instructions, exclusion of evidence, or in serious cases, default. Preservation letters sent promptly after a crash document the date the duty to preserve attached.
Statutory and regulatory framework summarized
The federal hours-of-service framework lives in 49 C.F.R. Part 395 and is enforced by FMCSA. Recordkeeping obligations are in 49 C.F.R. 395.8 (records of duty status), 395.11 (supporting documents), and 395.22 through 395.38 (ELD requirements). Georgia incorporates these federal motor carrier safety regulations for intrastate operations through O.C.G.A. 40-1-8 and the rules of the Georgia Department of Public Safety.
Practical evidentiary picture
In practice, a Georgia hours-of-service case is rarely proven from a single source. The case is built through multiple overlapping records: the ELD output, supporting documents, third-party data, and carrier files cross-checked against each other. Inconsistencies among these sources tend to be the strongest indicator of a violation. Discovery requests are usually framed to capture all categories at once so the timeline can be reconstructed without gaps.
Understanding the categories of available proof, the federal rules that create them, and the Georgia procedural tools used to obtain them is the foundation for evaluating a hours-of-service issue in any Georgia truck-crash lawsuit.
