What We Do
Clarity Backed by Science and Testing
At Billy Cox Group, we combine decades of experience with real-world crash testing to deliver objective, data-driven analysis. Our services are designed to help attorneys, insurers, and production teams understand the mechanics of a crash, the forces involved, and the resulting injuries.
Every engagement is rooted in measurable evidence—not assumptions—ensuring that conclusions can stand up to scrutiny in the courtroom and beyond.
Our Core Service
Crash Reconstruction & Analysis
We reconstruct vehicle collisions using physical evidence, vehicle data, scene analysis, and advanced methodologies to determine how and why an incident occurred. Our process evaluates vehicle movement, impact angles, speeds, and contributing factors to establish a clear sequence of events.
Our findings provide attorneys and insurers with a reliable foundation for decision-making, negotiation, and litigation.
- Collision dynamics and vehicle movement
- Speed and impact analysis
- Scene and evidence interpretation
- Event sequence reconstruction
IMPACT BIOMECHANICS
Understanding How Injuries Occur
Impact biomechanics focuses on how forces from a collision affect the human body. Through analysis and testing, we evaluate occupant motion, restraint system performance, and injury mechanisms to determine whether claimed injuries are consistent with the crash event.
This work bridges the gap between science-based forensic analysis and medicine—providing insight into causation, severity, and plausibility of injury claims.
- Occupant kinematics (movement during impact)
- Injury causation analysis
- Seat and restraint system evaluation
- Correlation between forces and physical outcomes
CRASH DATA RETRIEVAL
Extracting the Truth from Vehicle Data
Modern vehicles contain critical data that can provide insight into pre-impact conditions and driver inputs. We retrieve and interpret event data recorder (EDR) information to analyze factors such as speed, braking, throttle position, and seatbelt usage.
This data enhances reconstruction accuracy and provides objective support for case findings.
- Event Data Recorder (EDR) downloads
- Pre-impact vehicle behavior analysis
- Correlation with physical evidence
- Data validation and interpretation
