Commercial vehicle litigation is regulatory litigation. Unlike an ordinary automobile case, where the standard of care is what a reasonably prudent driver would do, a trucking case is measured against a codified federal rulebook that dictates who may drive, how long they may drive, how the vehicle must be maintained, what must be recorded, and how long those records must be kept. That structure produces a case built on documents, and the practical outcome frequently depends on how quickly counsel moves to preserve them.
The scale is substantial. NHTSA reports that 5,936 people were killed in traffic crashes involving large trucks in 2022, a 2% increase over 2021, and that 70% of those killed were occupants of other vehicles 1. That asymmetry — the occupants of the passenger vehicle bear the fatalities — shapes both the damages profile and the jury dynamics of these cases.
Fatigue remains the most litigated theory, and the governing limits are specific. Under 49 CFR § 395.3, a property-carrying driver may drive a maximum of 11 hours following 10 consecutive hours off duty, may not drive after a period of 14 consecutive hours after coming on duty, may not drive if more than 8 hours have passed without a consecutive 30-minute interruption of driving status, and may not drive after being on duty 60 hours in 7 consecutive days (carriers not operating every day) or 70 hours in 8 consecutive days (carriers operating every day), with those periods restartable by 34 or more consecutive hours off duty 2.
Because electronic logging devices now capture duty status automatically, the modern dispute has moved from whether the paper log was falsified to how the electronic record was manipulated: unassigned driving time, personal conveyance and yard move status misuse, edits and annotations, and the reconciliation of ELD data against fuel receipts, toll transactions, dispatch messages, bills of lading, GPS telematics, and engine control module data. The driver's record of duty status requirements at 49 CFR § 395.8 define what must be captured and retained 3. Where the ELD record and the supporting documents diverge, the divergence itself is the evidence.
The higher-value theories usually target the motor carrier rather than the driver, and each maps to a specific part of the regulations:
A fifth theory has grown quickly. Claims against freight brokers, shippers, and logistics intermediaries for negligent selection of an unsafe carrier turn on what public safety data was available at the time of the load tender and on the definitions and scope provisions in 49 CFR § 390.5 that determine which entity is an employer, motor carrier, or broker for regulatory purposes 7.
Most trucking evidence has a short life. ELD records, dispatch communications, telematics data, engine control module and event data recorder downloads, dashcam footage, and post-accident drug and alcohol test results are all subject to routine overwriting or retention limits measured in months. A spoliation letter that names each category specifically, issued within days rather than weeks, is often worth more to the case than any expert opinion. Counsel should also obtain the carrier's own investigation file, its safety policies and driver handbook, prior similar incidents, and its federal safety measurement data.
There is no license or board certification for trucking safety expertise, which makes the expert's actual background decisive. The strongest witnesses are former carrier directors of safety, former state or federal commercial vehicle enforcement investigators, and career fleet compliance professionals who have written the policies and audited the files that are now in evidence. Match the witness to the theory: an accident reconstructionist addresses speed, sight lines, and avoidance; a trucking safety expert addresses the carrier's regulatory compliance and safety management; a mechanical or vehicle systems expert addresses brake performance, tire failure, or underride protection. Blending those roles in a single witness invites a Daubert challenge on the portions outside the expert's demonstrated experience.

FAQ
There is no board certification in trucking safety, so the background is the credential. The most effective witnesses are former carrier directors of safety, former federal or state commercial vehicle enforcement investigators, and career fleet compliance professionals who have personally built driver qualification files, audited ELD exception reports, and managed maintenance programs. Look for someone who has been responsible for the systems now being criticized, not someone whose experience is limited to litigation consulting.
For property-carrying drivers, 49 CFR § 395.3 sets an 11-hour maximum driving time after 10 consecutive hours off duty, a 14-consecutive-hour window after coming on duty within which driving must occur, a required 30-minute interruption of driving status before exceeding 8 cumulative hours of driving, and weekly limits of 60 hours in 7 consecutive days for carriers not operating every day or 70 hours in 8 consecutive days for carriers that do. Either weekly period may be restarted by 34 or more consecutive hours off duty.
Send a specific spoliation letter within days. Name the ELD and supporting documents, dispatch and messaging records, GPS and telematics data, engine control module and event data recorder downloads, dashcam and any inward-facing camera footage, the driver qualification file, drug and alcohol testing records, the maintenance file and driver vehicle inspection reports for the tractor and trailer, the bill of lading and weight tickets, and the carrier's own post-accident investigation. Much of this data is overwritten on cycles measured in weeks or months.
It is an actively litigated theory. Claims for negligent selection of a motor carrier turn on what publicly available safety data existed at the time the load was tendered, what the intermediary's own carrier vetting standards required, and whether those standards were followed. The regulatory definitions in 49 CFR § 390.5 matter because they determine whether an entity is acting as a motor carrier, a broker, or an employer for purposes of the federal safety regulations, which in turn affects preemption and duty arguments.
In most catastrophic cases, yes. They answer different questions. The reconstructionist addresses speed, braking, perception-reaction, sight distance, and whether the collision was avoidable. The trucking safety expert addresses whether the driver should have been behind the wheel at all, whether the vehicle should have been on the road, and whether the carrier's safety management systems permitted a known risk to persist. Asking one witness to do both invites a challenge to the portion outside their demonstrated experience.
In general, transportation expert fees are determined by the expert themselves, based on a variety of criteria. Among those criteria are professional experience, forensic experience, industry certifications, regulatory knowledge, and publications. Vident does have some influence over expert fees by comparing experts within a specialty, but ultimately it is a personal decision by the expert.
