Collision Reconstruction
Serving Attorneys, Insurers & Agencies
Gerald McDevitt provides detailed collision reconstruction services for a wide range of incident types, including passenger vehicles, commercial trucks, motorcycles, pedestrians, and specialized transportation cases.
Each reconstruction is based on physical evidence, digital data, and scientifically accepted methodologies to determine how and why a collision occurred. The goal is to produce accurate, defensible findings suitable for litigation and courtroom presentation.
EXPERT SUPPORT FOR ATTORNEYS, INSURERS & INVESTIGATORS
Gerald McDevitt performs collision reconstruction as the scientific analysis of traffic and transportation incidents, determining the sequence of events, contributing factors, and underlying causes.
He evaluates physical evidence, including vehicle damage, scene measurements, roadway conditions, and digital data such as Event Data Recorder (EDR) information.
Gerald McDevitt develops all findings using validated scientific principles to ensure accuracy, reproducibility, and admissibility in court.
Key Areas of Analysis

- Vehicle–pedestrian collisions
- 3D reconstruction for court
- Driver perception-reaction time analysis
- Occupant kinematics and driver identification
- DUI / DWI fatality cases
- Commercial & emergency vehicle accidents
- Pre-impact speed and braking analysis
- Point of impact and post-impact movement
Types of Collision Cases Handled
Passenger Vehicle Collision
The majority of serious and fatal collisions involve passenger vehicles. Gerald McDevitt reconstructs the full sequence of events — pre-impact speed, braking, evasive action, point of impact, and post-impact movement — using physical evidence, roadway data, and vehicle EDR information to produce findings that withstand courtroom scrutiny.
Low Delta-V / Disputed Injury
Gerald McDevitt reconstructs low delta-V collisions using engineering analysis to evaluate the forces involved and occupant kinematics — including occupant position and movement during the collision sequence. For cases that specifically require injury causation opinions or biomechanical body modeling, McDevitt and Associates, Inc. coordinates with qualified biomechanical specialists identified and approved by retaining counsel.
Motorcycle Accident
Motorcycle collisions present unique reconstruction challenges including pre-impact positioning, rider behavior, roadway surface conditions, and vehicle-to-vehicle contact geometry. Gerald McDevitt applies validated methodology to determine speed, point of impact, and causation — findings that are defensible under Daubert and Frye admissibility standards.
Hit-and-Run
Hit-and-run reconstruction requires identifying a suspect vehicle through trace evidence, damage patterns, paint transfer, and scene geometry. Gerald McDevitt documents and analyzes all available physical evidence to establish vehicle contact signatures, direction of travel, and post-impact departure path — providing investigators and attorneys with scientifically supported conclusions.
Pedestrian / Bicyclist Accident
Pedestrian and bicyclist collisions require specialized analysis of impact dynamics, throw distance, point of impact, pre-impact visibility, and lighting conditions. Gerald McDevitt has extensive experience with pedestrian fatality cases involving complex impact kinematics.
Commercial Vehicle Accident
Commercial vehicle collisions — involving tractor-trailers, delivery vehicles, buses, and fleet vehicles — frequently involve federal regulatory compliance issues, electronic logging devices (ELD), and complex vehicle dynamics. Gerald McDevitt reconstructs these incidents with the same scientific rigor applied to all casework, including EDR and ECM data extraction.
Military Court-Martial (UCMJ)
McDevitt and Associates, Inc. provides forensic reconstruction analysis for UCMJ court-martial proceedings involving vehicular manslaughter (Article 119), negligent homicide (Article 134), vehicular homicide, and felony DUI, and related offenses. Gerald McDevitt is a U.S. Air Force veteran who has been qualified as an expert in U.S. military courts. Retainer waived for UCMJ cases.
DUI / Vehicular Homicide
Cases involving alcohol or drug impairment and a resulting fatality require reconstruction that accurately establishes pre-impact speed, braking behavior, reaction time, and causation. Gerald McDevitt’s analysis is structured to meet the evidentiary demands of criminal prosecution and defense, with findings expressed to a reasonable degree of scientific and engineering certainty.
Technology & Methodology
Gerald McDevitt supports each reconstruction with case-appropriate technology, including Recon3D LiDAR scanning, Total Station surveying, Emlid RS3 GNSS, UAV/Drone Photogrammetry, and Racelogic VBOX GPS data logger for speed and motion data. All analyses are conducted using scientifically accepted methodologies to produce defensible, reproducible results suitable for deposition and trial testimony.
These technologies allow for precise scene documentation, accurate measurements, and reliable reconstruction of complex collision events.
Courtroom-Ready Analysis & Expert Testimony for Legal Cases
Gerald McDevitt prepares all findings for use in legal proceedings, including deposition and trial testimony. Each case is structured to meet Daubert and Frye admissibility standards, ensuring that conclusions are reliable, scientifically supported, and defensible under cross-examination.
