Accident Reconstruction

An accident reconstruction is a scientific approach to solving the questions of how and why an accident occurred. Reconstructing accidents requires a methodology that begins with known data such as vehicle final rest positions, accident scene evidence and vehicle damage.

Our Accident Reconstructionists are ACTAR Certified and conduct in-depth collision analysis and reconstruction to identify the collision causation and contributing factors in different types of collisions, including the role of the driver(s), vehicle(s), roadway and the environment. Our accident reconstruction are law enforcement specialists and provides rigorous analysis that the expert can present at trial.

Forensic Analysis

Accident reconstructions are often done when personal injury is involved and in some cases involving fatalities. Our experts are prepared to defend their scientific based analysis and conclusions in court.

The Accident reconstructionist examines physical, pictorial and document evidence to supply an opinion as to what really happened in an auto accident. Usually issues have arisen between claimant or plaintiff and insured as to what speeds were involved (vehicle dynamics), who was driving within the law and who wasn’t, who turned legally and who didn’t, and many other questions relating to “Who caused the accident?” Commonly asked questions are, “Both drivers said they had the green light, so which one really did?” and “What were the speed and g-forces and probability for injuries in this accident?” Garrett’s reconstructionist, as his name indicates, reconstructs what happened during the accident.

Site Inspections

Scene inspections and data recovery involves visiting the scene of the collision and investigating all of the vehicles involved in the collision. Our experts conduct an inspection of the accident site to determine aspects of the accident, including: road conditions,  line of sight, brake skid marks, traffic controls & signage, and site measurements.

Vehicle Inspections

Our experts will conduct a physical inspection of the vehicle(s), take photographs and measurements, to determine the extent of the damage.  Speed and g-force calculation can be determined by examination of the crush damage. Data from the Event Data Recorder (EDR) also provides valuable information such as the speed of the vehicle a few seconds before the collision, brake status, throttle position, ignition cycles, delta-V, seat belt status, time between events, and others.

Event Data Recorder Download & Analysis

How fast was the car going when it crashed?
Was the driver on the gas or on the brakes?
What are the probabilities for injury?
What was the Delta V?

Its Best To Know What Really Happened!

The Event Data Recorder, is a module that constantly monitors vehicle operating conditions such as engine speed, vehicle speed, percent throttle, braking, Delta V, etc. In the event of a collision, the last seconds of data prior to the crash can be recorded on a computer chip for retrieval.

The available information depends upon the manufacturer and make/model/year of the vehicle – the most useful information is Vehicle Speed (mph), Throttle Position (% open), Engine Speed (rpm), Seat Belt Usage (latched or not), Delta V (the total change in vehicle velocity over the duration of the crash event), time between events, and the brake circuit activation state (on or off) relative to the air bag deployment event, etc.

When an air bag deploys, very useful information about that event may be stored in the Vehicle’s Event Data Recorder (EDR). Garrett’s experts, who have completed the authorized Bosch CDR Technician Course, utilize Bosch equipment to download the data from your insured’s or claimant’s vehicle. With this information, our Certified EDR analyst then interprets the EDR data, and uses this information, along with photographs, police reports, witness statement, repair estimates, etc., for accident reconstruction and to help determine what really happened.

When our Accident Reconstructionists are working a case, the more information they have, the more he/she will be able to let you know “What Really Happened.”

Use this information to verify your client or insured’s statement.

Protect your company from allegations of intentional spoliation by gathering and preserving the information now, while it is still available. This information may be critical for a complete situational analysis and accident reconstruction.
