EDR (BLACK BOX) ANALYSIS

Data That Tells the Truth. Analysis That Drives the Case.
Event Data Recorders (EDR), also known as “Black Boxes,” capture critical information in the moments before, during, and after a crash. Dr. McElroy retrieves, decodes, and interprets this data to provide clear, scientific answers for your case.

WHAT IS AN EDR?

An Event Data Recorder (EDR) is a sophisticated data recording device installed in modern vehicles. It captures a snapshot of critical vehicle parameters in the seconds before, during, and after a collision.

Installed in most 2006+ vehicles

Captures data in real-time

Records critical crash events

Retrievable & decodable

Provides objective, reliable facts

DATA WE RETRIEVE & ANALYZE

Pre-Crash Data

Vehicle speed, engine RPM, throttle position, braking activity, and more before impact.

Crash Event Data

Airbag deployment, impact severity, crash pulse, and restraint system status.

Vehicle Dynamics

Speed, direction, yaw rate, ABS activity, and stability control engagement.

Driver Inputs

Accelerator position, brake application, steering input and gear selection.

Occupant Information

Calculate pre-impact speeds and determine vehicle paths using scientific methods.

Turning Data Into Answers

We analyze EDR (Black Box) data with precision and correlate it with crash scene evidence to provide a clear, objective understanding of what happened. Our analysis helps attorneys, insurance companies, and investigators build stronger cases with reliable, court-ready evidence.

Objective, Time-Stamped Data from the Vehicle

We retrieve and analyze EDR data that provides an accurate, time-stamped record of the vehicle’s operation before, during, and after the crash.

Correlates EDR Data with Crash Scene Evidence

We combine EDR data with physical evidence from the crash scene to build a complete and accurate picture of the events.

Determines Pre-Crash Speed and Driver Actions

Our analysis reveals vehicle speed, braking, throttle position, and other driver inputs leading up to the crash.

Reveals Critical Details Not Visible at the Scene

EDR data uncovers data points and timing information that are not apparent during a visual inspection of the crash scene.

Helps Establish Fault, Refute Claims, or Support Reconstruction

The data provides objective facts that help determine what happened, who was at fault, and supports or challenges existing claims.

Clear, Easy-to-Understand Reports for Attorneys and Courts

We deliver detailed, well-organized reports with easy-to-follow charts, diagrams, and technical analysis.

Expert Testimony & Court-Ready Exhibits

Dr. McElroy provides expert testimony and prepares visual exhibits to help present the evidence clearly and effectively in court.

Supports Insurance & Litigation Decision-Making

Objective vehicle data and technical findings give attorneys, insurers, and investigators reliable information to evaluate claims, understand the evidence, and make informed case decisions.
