Accident Reconstruction

End-to-End Accident Reconstruction Investigative Process

Accident reconstruction is the scientific process of investigating, analyzing, and drawing conclusions about the causes and events during a vehicle collision. When our clients have unanswered questions — what happened, how it happened, and what factors caused or contributed to the collision — YA Group provides accident reconstruction expertise to deliver clear answers.

YA Group applies engineering analysis, physical evidence, recorded data, and testing to develop clear, objective accident reconstruction findings. Through advanced investigative technology and scientific analysis, we address the causes and contributing factors of vehicle collisions, workplace incidents, and premises-related injuries, as well as the nature and extent of the resulting damage.

Vehicle Collisions We Reconstruct

YA Group’s accident reconstruction experts specialize in the complex reconstruction of crashes involving passenger cars, light trucks and SUVs, heavy trucks and buses, motorcycles, bicycles, pedestrians, and personal mobility vehicles, including all combinations of these. Our engineers draw on extensive knowledge of light and heavy vehicle dynamics, braking, suspension, and steering systems developed through industry experience and specialized training in vehicle design and accident reconstruction.

Passenger vehicle collisions — cars, light trucks, SUVs, and vans, including single-vehicle, intersection, rear-end, side-impact, and rollover events

Pedestrian and bicycle collisions — throw distance and impact speed analysis, pre-impact movement, visibility and sightline conditions, and rider or pedestrian kinematics

Motorcycle collisions — a distinct discipline with its own dynamics, data sources, and evidence

Commercial vehicle collisions — heavy trucks, buses, and RVs, including air brake systems and regulatory compliance

Personal mobility and micromobility — e-bikes, scooters, and similar vehicles, an increasing share of the matters we are retained on

Off-highway and workplace incidents — equipment, industrial vehicles, and premises-related injury events

Vehicle Accident Reconstruction Inspections and Scene Documentation

For light vehicles such as passenger cars, trucks, SUVs, motorcycles, and other personal mobility vehicles, we conduct mechanical inspections to evaluate post-crash vehicle condition. 3D laser scanning, LiDAR, and photogrammetry may be used to create measured models of vehicle geometry and crush profiles that support vehicle damage analysis and crash reconstruction.

YA Group uses advanced 3D scanning and drone technology as part of forensic accident reconstruction when appropriate. With Leica and Faro scanners and drones, we can document accident sites in 360° and capture features such as pavement gouges, roadway geometry, and overhead features. This documentation provides a measured record that can be compared with scene photographs, video, and other evidence.

Analysis and Interpretation

Our capabilities do not end with our ability to capture data; our strength is in our ability to analyze and interpret the data we collect. Crush profile measurement and damage analysis, momentum and energy methods, time-distance and sight-distance analysis, and physics-based simulation are applied as the evidence and the questions presented warrant to support objective collision reconstruction analysis.

Our team’s experience and specialized training support careful forensic accident reconstruction and analysis of light and heavy vehicle accidents and technically supported conclusions for legal cases, insurance claims, and safety reviews.

Communicating the Findings

Explaining a collision to a judge, jury, or mediator is its own discipline. Our accident reconstruction work is supported by forensic animation, 3D scene documentation, and trial graphics produced by our visualization team, and by expert testimony and demonstrative support through our litigation support practice. An exhibit is only as good as the analysis behind it, which is why those groups work the same matters with us rather than after us.
