Heavy Vehicle Investigation

Proper analysis of heavy vehicle accidents requires personnel with knowledge, experience and training far more specialized than that of the average vehicular accident investigator, reconstructionist or engineer.

Ruhl Forensic staff includes engineers and law enforcement personnel trained in vehicle dynamics, testing, accident investigation and reconstruction. Our experienced tractor-trailer drivers/instructors have driven millions of miles and can testify as to proper professional driver training, supervision and motor carrier compliance with federal regulations. Some of the issues we address are truck weight and length, cargo, containment, vehicle articulation, dynamics and mechanical/pneumatic/hydraulic systems operations. Several staff members have also had long careers in law enforcement, enforcing the Federal Motor Carrier Safety Regulations. Staff addresses standards of care and custom and practice in the trucking industry.

The investigation stage of a collision may start with a state-of-the-art electronic survey of the collision site and vehicles to document and preserve evidence. Other data and statements can be used to build a computer simulation of the vehicles and terrain in order to "turn back the clock" and determine vehicle speeds, positions and travel paths prior to, during and post-impact. The results can be provided in various forms including written and oral reports, video recreation, and 2D or 3D models for courtroom presentation.

Heavy vehicle accidents are unique. Our book Truck and Trucking Handbook: A Primer addresses basic knowledge with respect to heavy vehicle systems and regulation.

Heavy vehicles must be driven and managed in a professional and safe manner. Ruhl Forensic staff is highly experienced in addressing the unique issues involved in the analysis of accidents involving heavy vehicles.
