Collisions involving tractor-trailers and other commercial motor vehicles (CMVs) are among the most complex — and the most data-rich — incidents we investigate. Kerley Reconstruction reconstructs heavy-vehicle crashes by combining physical evidence and vehicle dynamics with the extensive electronic data that modern commercial vehicles generate. From engine and braking data to telematics and onboard video, we build a complete, defensible picture of how a collision occurred and what contributed to it. Our findings equip attorneys, insurers, and trucking companies with the information they need for litigation, claims, and risk mitigation. Trust Kerley Reconstruction to uncover the truth behind every commercial vehicle incident.
Heavy-Vehicle Collision Reconstruction
Commercial vehicles behave very differently from passenger cars — their mass, braking characteristics, and trailer dynamics change how a collision unfolds. We reconstruct jackknifes, underride and override collisions, rollovers, and multi-vehicle crashes using physical evidence, momentum and energy analysis, and a detailed understanding of heavy-vehicle behavior to establish speeds, positions, and the sequence of events.
Electronic Data & Event Recorder Recovery
Modern commercial vehicles are rolling data networks. Depending on the make, model, and year, we identify, preserve, and analyze information from engine control modules and heavy-vehicle event data recorders (HVEDR), airbag and restraint control modules, electronic logging devices (ELDs), collision-mitigation systems, GPS and telematics, and onboard AI camera systems. These sources can capture pre-crash speed, braking, throttle, steering, following distance, and critical events such as hard braking or lane departure — often in the seconds before impact. Because the data available varies significantly between vehicles and systems, we determine what each specific unit recorded and how best to recover it.
Regulatory & Human Factors Analysis
Understanding a commercial crash means understanding the rules and decisions behind it. We consider federal motor carrier regulations, hours-of-service and driver-fatigue factors, and the behavior captured across a vehicle's electronic systems to assess causation. This combined approach ties the physical and electronic evidence to a clear, authoritative determination of contributing factors — valuable for legal proceedings, insurance claims, and carrier risk mitigation.
