Truck Crash Case Guide

Critical Evidence in a Truck Crash Case

Every truck operating in interstate commerce generates a trail of data and documentation governed by federal regulations. When a crash happens, this evidence becomes the foundation of your case. Here’s what matters most:

Electronic Control Module (ECM) Data

The ECM — often called the truck’s “black box” — records critical data including speed, braking patterns, throttle position, engine RPM, and sometimes GPS location in the moments before and during a crash. This data can prove whether the driver was speeding, braked too late, or was driving erratically. ECM data can be overwritten as the truck continues to operate, which is why a spoliation notice must be sent immediately.

Electronic Logging Device (ELD) Records

Since the FMCSA’s ELD mandate went into full effect, most commercial drivers must use electronic logging devices to record their hours of service. ELD data reveals whether the driver was in compliance with federal driving limits at the time of the crash — or whether they were driving while fatigued in violation of the law. ELD data also shows unassigned driving time, edits to log entries, and patterns of manipulation.

Driver Qualification Files

Under 49 CFR Part 391, carriers must maintain a qualification file for every driver. This file includes the driver’s employment application, driving record (MVR), medical examiner’s certificate, road test results, and drug and alcohol testing records. Driver qualification violations — like an expired medical certificate or a failed drug test — can establish that the carrier knew or should have known the driver was unfit to operate a CMV.

Maintenance and Inspection Records

Daily Vehicle Inspection Reports (DVIRs), scheduled maintenance logs, and repair orders document the mechanical condition of the truck before the crash. Under Part 396, carriers must systematically inspect, repair, and maintain their vehicles. Missing or incomplete records suggest the carrier failed to meet these obligations. A history of DOT out-of-service violations further demonstrates a pattern of neglect.

Post-Crash Drug and Alcohol Testing

Federal regulations under 49 CFR Part 382 require post-accident drug and alcohol testing of CMV drivers involved in crashes that result in fatalities, bodily injury requiring medical treatment away from the scene, or vehicle towing. This testing must occur within specific timeframes — alcohol testing within 8 hours, drug testing within 32 hours. Failure to conduct or document these tests is itself a serious regulatory violation.

Spoliation Notices: Why Speed Matters

A spoliation notice is a formal legal demand sent to the trucking company, its insurer, and any other potentially responsible parties, requiring them to preserve all evidence related to the crash. This includes:

• ECM/black box data
• ELD records and driver logs
• Driver qualification files
• Maintenance and inspection records
• GPS and telematics data
• Dispatch records and communications
• Post-crash photographs and vehicle condition reports
• Drug and alcohol test results
• Insurance policy documentation

Federal record retention requirements vary by document type — some records must only be kept for six months, others for three years. Without a spoliation notice, companies can legally destroy evidence that would have proven your case. Carriers that destroy evidence after receiving a spoliation notice face severe legal consequences, including adverse inference instructions that tell the jury the destroyed evidence would have been unfavorable to the carrier.

How Trucking Companies Try to Limit Your Claim

Trucking company defense tactics are designed to limit their financial exposure. These tactics start immediately after a crash and include:

• Sending rapid-response teams to the crash scene — Carriers dispatch their own investigators, often within hours, to photograph the scene, interview witnesses, and begin building a defense narrative before you’ve even left the hospital.
• Shifting blame to the injured driver — Adjusters and defense attorneys will scrutinize your driving behavior, cell phone records, and medical history looking for anything that can be used to reduce your claim under Kentucky’s comparative fault rules.
• Offering quick, lowball settlements — Early settlement offers are designed to close your claim before the full extent of your injuries — and the carrier’s liability — becomes clear.
• Destroying or “losing” evidence — Even with legal obligations to preserve records, some carriers will claim data was overwritten, records were misfiled, or documents were lost.

Building a Maximum-Value Truck Crash Claim

The strongest truck crash cases are built on a foundation of preserved evidence, identified violations, and thorough documentation of damages. Here’s the framework our team follows:

1. Immediate evidence preservation

   Spoliation notices go out within 24-48 hours. ECM data preservation is demanded. The truck and trailer are inspected if possible.

2. FMCSR compliance review

   We review the carrier’s CSA scores, inspection history, and safety record. We examine the driver’s qualification file, hours-of-service records, and drug testing history. We identify every FMCSR violation relevant to the crash.

3. Crash reconstruction and liability analysis

   When the facts warrant it, we retain accident reconstruction professionals to analyze the physical evidence, vehicle dynamics, and crash sequence. This analysis often reveals contributing factors that aren’t apparent from the police report alone.

4. Full damages documentation

   We document every category of damage — medical expenses (past and future), lost income, diminished earning capacity, pain and suffering, and all other losses. For catastrophic injuries like spinal cord injuries, brain injuries, or burn injuries, we work with medical and economic consultants to project lifetime costs.

5. Demand and negotiation (or litigation)

   We present the evidence to the carrier’s insurer in a comprehensive demand package. If the insurer won’t pay what the case is worth, we take the case to court. Our no increased litigation fees fee never increases for litigation — unlike firms that bump to 40% or more.
