What Your Truck Accident Wrongful Death Lawyer Must Do Immediately

The driver's ELD records are the single most important piece of evidence in any commercial truck accident. These logs show whether the driver was operating in violation of the 11-hour driving limit, the 10-hour mandatory rest requirement, or the 60-hour-in-7-days rule. Under [49 CFR § 395.8](https://www.fmcsa.dot.gov/regulations-guidance/rules-and-regulations), trucking companies must retain ELDs for six months minimum. However, many carriers delete data after disputes or litigation threats. A preservation letter must reach the motor carrier within 48 hours of a fatal crash. This letter creates a legal duty to maintain all electronic records or face sanctions and spoliation inferences in discovery. Without those logs, proving an hours-of-service violation—a major negligence indicator—becomes nearly impossible. The ELD data often determines whether the case settles in six figures or seven figures.

The driver's qualification file is a federal requirement under [49 CFR § 391.51](https://www.fmcsa.dot.gov/regulations-guidance/rules-and-regulations). It must contain the driver's application, previous employment records, driving history, and DOT medical certificate. Medical certification issues—failed physicals, disqualifying conditions, expired certificates—show the motor carrier knew or should have known the driver was unfit. Many fatal truck accidents involve drivers who should never have been behind the wheel: drivers with untreated sleep apnea, drivers with vision defects beyond the DOT standard, drivers with a history of moving violations or safety violations. Requesting the DQF during discovery reveals whether the carrier violated its own hiring obligations. If the DQF is incomplete or falsified, that's not just negligence—it's a willful violation that strengthens a wrongful death claim and can support punitive damages in most jurisdictions.

The Compliance, Safety, and Accountability (CSA) program is public-facing FMCSA data that rates every motor carrier. The CSA score measures violations across seven categories: unsafe driving, hours-of-service compliance, driver fitness, controlled substances and alcohol, vehicle maintenance, hazmat compliance, and crash indicators. If a carrier's CSA score is above the intervention threshold in unsafe driving or hours-of-service—numbers published by FMCSA—that's direct evidence of a pattern of negligence. It establishes that the motor carrier had prior notice of safety problems before this particular crash. A CSA score above 65 in unsafe driving is a strong foundation for holding the carrier liable independent of the individual driver's conduct. Any DOT Safety Audits the carrier has undergone will show what violations were documented and what corrective actions (if any) were supposedly taken. High CSA scores combined with fatal crashes often indicate negligent retention and negligent entrustment.

Wrongful death cases in commercial truck accidents depend on accurate accident reconstruction. The weight difference between a loaded 18-wheeler (up to 80,000 pounds) and a typical passenger car (3,000 to 4,000 pounds) means the crash dynamics are catastrophic and one-directional. Your lawyer must immediately obtain the police crash report, photographs and video from the scene, measurements of skid marks and vehicle positions, dashcam footage from nearby vehicles or traffic cameras, and data from the truck's onboard safety systems. Many smaller carriers and owner-operators do not have event data recorders, but larger fleets often do. Trucking companies sometimes remove data recorders or claim equipment malfunction to avoid producing damaging data. A preservation letter must specifically demand all event data, telematics, and onboard diagnostics. Accident reconstruction experts can then determine whether the truck was speeding, braking inappropriately, following too closely, or drifting out of lane.

Dispatch records and communications between the driver and the carrier often reveal pressure to violate hours-of-service rules. A dispatcher telling a driver, 'Just get it there by tonight,' when the driver is already at the legal HOS limit is direct evidence of negligent entrustment. Text messages, radio logs, and email correspondence between dispatch and the driver paint a picture of the carrier's culture around safety. If the crash happened during a delivery window that was impossible to meet within HOS rules, that's evidence the carrier scheduled the route knowing a violation would occur. Additionally, review whether the driver was paid on a per-mile or per-load basis—compensation models that incentivize speeding or HOS violations show the carrier profited from dangerous behavior. Dispatch records that show awareness of violations strengthen a wrongful death claim by proving the carrier's negligence was not accidental—it was structural and foreseeable.

In wrongful death truck cases, the motor carrier is not always the only defendant. The shipper (the company sending the load), the broker (the intermediary who arranged the shipment), and the trailer owner (if different from the motor carrier) may all bear independent liability. A shipper can be liable for improper loading or failing to disclose hazardous conditions. A broker can be liable for hiring an unsafe carrier or arranging impossible schedules. A trailer owner can be liable for poor maintenance of the trailer's brakes, axles, or coupling system. These entities often have separate insurance policies with higher limits than the motor carrier itself. In a wrongful death context where lifetime medical care, lost wages, and loss-of-life damages can exceed $2 million, identifying all liable parties and their insurance is critical. Your lawyer must determine who controlled each link in the chain: who hired the carrier, who set the delivery deadline, who loaded the cargo, who maintained the equipment.

Federal regulations require post-crash drug and alcohol testing for the driver if a fatal accident occurs. The driver's post-crash drug screen results are critical evidence. However, many carriers mishandle this testing: they fail to conduct tests, delay testing (allowing time for drug metabolites to clear), or fail to preserve samples for independent testing. If the post-crash screen is positive, that's powerful evidence of driver negligence. But if the carrier failed to test or destroyed the sample before the plaintiff's expert could independently verify it, that's spoliation—and courts often allow juries to infer the test would have been positive. Even a negative drug screen does not clear the driver or carrier: the crash may still have been caused by hours-of-service violations, mechanical failure, or improper cargo loading. Your lawyer must demand the original drug screen results, the chain of custody for the sample, and the qualifications of the testing lab.

The preservation letter is the legal mechanism that stops the clock on a motor carrier's right to delete evidence. Once received, the carrier must retain all evidence until litigation concludes or a court orders destruction. Failure to do so can result in sanctions, contempt findings, or even a default judgment in the plaintiff's favor. In wrongful death cases, preservation is existential. A single deleted ELD file, a lost dispatch email, or a destroyed dashcam recording can destroy your ability to prove negligence. Your lawyer must send preservation letters to the motor carrier, the insurance carrier, the broker, the shipper, and any third parties who may have evidence. These letters should specifically identify ELDs, maintenance records, dispatch communications, drug screen samples, insurance policies, and any video footage. Document the date the letter was sent, the method of delivery (certified mail, email with read receipt), and who received it. If the carrier later claims it routinely deletes data and cannot recover it, the preservation letter creates an inference that the destroyed data was unfavorable—and courts allow juries to use that inference in calculating damages.
