Event Data Recorder Retrieval and Analysis for Motor-Vehicle Claims and Litigation
Objective Vehicle Data for Claims, Investigations, and Litigation
Vehicle collisions frequently involve conflicting accounts, incomplete evidence, and disputed questions concerning speed, braking, steering, vehicle movement, restraint use, and driver actions. Event Data Recorder information may provide objective vehicle data that helps explain the circumstances surrounding a qualifying crash event.
Crenshaw Investigations provides forensic EDR/CDR retrieval, vehicle inspection, photographic documentation, data analysis, and reporting services throughout California. Our certified EDR/CDR experts inspect and photograph vehicles; retrieve and preserve available crash data; document vehicle condition, damage, restraint systems, and the retrieval process; analyze recorded information; and prepare clear written reports tailored to the assignment.
We serve attorneys and law firms representing plaintiffs and defendants, insurance companies and claims professionals, businesses, individuals, and vehicle owners. Depending on the vehicle and requested scope of work, our capabilities include Bosch Crash Data Retrieval, Tesla crash-data retrieval, and Hyundai/Kia-supported EDR retrieval. Available information varies by vehicle make, model, model year, installed systems, event type, recording threshold, and module condition.

What is an Event Data Recorder Analysis?
An Event Data Recorder, commonly called an EDR or vehicle “black box,” is a function within certain vehicle electronic modules that may record technical information before, during, and immediately after a qualifying crash event.
The EDR is different from the equipment and software used to retrieve its information. Retrieval systems communicate with applicable vehicle modules to image and preserve available data; the retrieval equipment is not itself the EDR.
EDR analysis involves more than producing a manufacturer-generated report. Recorded values must be evaluated using vehicle-specific definitions, event status, timing, sign conventions, recording limitations, inspection findings, photographs, damage patterns, restraint-system conditions, and other available evidence.
Depending on the vehicle’s condition, retrieval may be completed through the diagnostic connector or directly from the applicable module when collision damage or electrical conditions prevent normal communication.
EDR/CDR Retrieval & Analysis Services
Depending on the vehicle, assignment, and requested scope of work, our services may include:
- Preliminary vehicle-support and retrieval-feasibility review
- On-site vehicle inspection and photographic documentation
- VIN, manufacturer-label, odometer, damage, and restraint-system documentation
- Retrieval through the vehicle’s diagnostic connector
- Direct-to-module retrieval when required by vehicle condition
- Bosch CDR, Tesla, and Hyundai/Kia-supported crash-data retrieval
- Preservation and delivery of available native data files and manufacturer-generated reports
- Written EDR retrieval and data-analysis reports
- Technical consultation regarding recorded findings and limitations
What Data May Be Available?
The information available varies by vehicle make, model, model year, installed systems, event type, and recording parameters. Depending on the supported vehicle and recorded event, available information may include:
- Pre-crash vehicle speed
- Service-brake status and brake-pressure information, where recorded
- Accelerator-pedal or throttle input
- Engine or electric-motor speed
- Steering input
- Stability-control and ABS activity
- Longitudinal and lateral delta-V
- Crash-pulse timing and event sequence
- Driver and passenger restraint status
- Airbag and pretensioner deployment commands
- Occupant-classification information, where recorded
- Ignition-cycle, odometer-at-event, and diagnostic information, where recorded
- Other manufacturer-specific vehicle and crash information
How Event Data Recorder Analysis Assists
Attorneys and Law Firms
EDR evidence can assist attorneys and law firms representing plaintiffs and defendants in evaluating disputed vehicle speed, braking, accelerator input, steering, vehicle movement, restraint use, airbag deployment, crash severity, and event sequence. Recorded vehicle information may help counsel compare objective electronic evidence with witness statements, police reports, photographs, repair records, damage patterns, and claimed collision circumstances. Depending on the matter, EDR retrieval and analysis may assist with case evaluation, discovery, mediation, settlement analysis, and litigation preparation.
Insurance Companies and Claims Professionals
EDR retrieval and analysis can assist insurance companies, claims professionals, Special Investigation Units (SIUs), corporate risk departments, and authorized business clients with liability evaluation, exposure assessment, claim verification, consistency analysis, suspected fraud and material misrepresentation inquiries, staged-loss investigations, subrogation, and coordination with counsel. Recorded vehicle information may help corroborate or challenge reported driver actions and collision circumstances by comparison with statements, vehicle damage, photographs, repair documentation, and other available evidence. EDR data does not independently establish fraud, but it may identify inconsistencies or information relevant to further claim or SIU investigation.
Individuals and Vehicle Owners
EDR data may help individuals and vehicle owners better understand recorded vehicle speed, braking, accelerator input, steering, restraint status, airbag deployment, and other available information surrounding a qualifying event. This information may assist with disputed accident circumstances, insurance claims, and legal matters by providing objective technical evidence concerning the vehicle’s recorded operation. Individuals who are represented may also have their attorney contact our office directly.
How EDR Evidence Can Change a Case
When collision accounts conflict, recorded vehicle data can provide objective information concerning speed, braking, accelerator input, steering, restraint systems, crash severity, and event timing. This information can help counsel move beyond competing statements and evaluate the matter using recorded evidence. Depending on the vehicle and event, these are among the principal data elements an EDR may contain.
Supporting a Driver’s Account of Evasive Action
Following a disputed intersection collision, the opposing party alleged that the driver never slowed or attempted to avoid the impact. The EDR documented accelerator release, brake application, speed reduction, steering input, and stability-control activity during the seconds before the collision.
The recorded information provided objective support for the driver’s account, helped counsel focus the disputed liability issues, and strengthened the factual basis for discovery, negotiation, and settlement evaluation.
Establishing the Sequence of a Chain-Reaction Collision
After a multi-vehicle rear-end collision, the parties disputed whether the subject vehicle initiated the sequence or was pushed into the vehicle ahead. The EDR documented sustained braking and significant speed reduction before the subject vehicle was struck from behind. Less than one second later, a second event was recorded when the subject vehicle was propelled forward into the vehicle ahead.
The pre-crash information and timing between the two events helped distinguish the initial rear impact from the subsequent front contact, providing counsel with meaningful evidence for evaluating the collision sequence and allocation of liability.
Preserving Critical Evidence from a Total-Loss Vehicle
A severely damaged vehicle had lost electrical power and was scheduled to be released for salvage. Because normal diagnostic-connector communication was unavailable, the applicable module was accessed directly and the recorded crash data was preserved before the vehicle became unavailable.
The retrieval secured potentially critical information concerning vehicle operation, driver inputs, restraint activity, and crash dynamics. This gave counsel an objective evidentiary foundation for early case evaluation, expert review, litigation planning, and settlement strategy.
