Vehicle Accident Data for Motor-Vehicle Claims and Litigation
Vehicle Accident Data from EDR/CDR Systems
Vehicle Accident Data refers to recorded vehicle information that may be preserved by a supported Event Data Recorder or related electronic module after a qualifying motor-vehicle accident.
Crenshaw Investigations provides EDR/CDR retrieval, vehicle inspection, photographic documentation, Vehicle Accident Data preservation, analysis, and written reporting for motor-vehicle claims, investigations, and litigation throughout California.
The information available varies by vehicle make, model, model year, installed systems, event type, recording threshold, event status, and module condition. Recorded data should be evaluated within those vehicle-specific parameters and in conjunction with the other evidence relevant to the assignment.
Have an active motor-vehicle matter, or want a practical overview of EDR evidence?
What Is Vehicle Accident Data?
Vehicle Accident Data in this context is information recorded by a supported Event Data Recorder or related electronic module when a collision or other qualifying event meets the vehicle’s recording criteria.
Depending on the vehicle, the available record may contain technical information from a short interval before impact, during the event, and immediately afterward.
Some supported vehicles may preserve one event, while others may contain multiple event records with different status, timing, pre-crash values, delta-V, restraint information, or deployment activity.
The presence of recorded data does not by itself establish fault or fully reconstruct a collision. The information should be interpreted using manufacturer-specific definitions and limitations and compared with the other available evidence.
Vehicle Accident Data / EDR Services
Depending on the vehicle, assignment, and requested scope of work, Vehicle Accident Data services may include:
- Preliminary vehicle-support and EDR feasibility review
- On-site vehicle inspection and photographic documentation
- Diagnostic-connector EDR/CDR retrieval
- Direct-to-module retrieval when required by vehicle condition
- Bosch CDR, Tesla, and Hyundai/Kia-supported crash-data retrieval
- Identification and preservation of available event records
- Preservation and delivery of native files and manufacturer-generated reports
- Evaluation of recorded parameters and vehicle-specific limitations
- Written EDR/CDR reporting and technical consultation
What Vehicle Accident Data May Be Available?
The information available as Vehicle Accident Data varies by vehicle make, model, model year, installed systems, event type, recording parameters, and module condition. 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
- Event status, event timing, and multiple-event information
- Ignition-cycle, odometer-at-event, and diagnostic information, where recorded
- Other manufacturer-specific vehicle and crash information
How Vehicle Accident Data Assists
Vehicle Accident Data for Attorneys and Law Firms
Recorded vehicle information may assist attorneys in evaluating disputed speed, braking, accelerator input, steering, restraint use, crash severity, event timing, and the sequence of multiple impacts. The data may be compared with statements, photographs, police reports, damage, repair records, and other evidence.
Vehicle Accident Data for Insurance and Claims Professionals
Claims professionals, SIUs, corporate risk departments, and authorized business clients may use EDR/CDR information to evaluate consistency, exposure, crash severity, event sequence, and technical questions requiring further investigation or coordination with counsel.
Vehicle Accident Data for Vehicle Owners
Vehicle owners may use recorded vehicle information to better understand what the applicable module preserved concerning pre-crash operation, restraints, deployment activity, delta-V, event timing, and other supported parameters surrounding a qualifying accident.
How Vehicle Accident Data Can Assist a Case
When accident accounts conflict or important vehicle actions are disputed, Vehicle Accident Data may provide objective technical information that can be evaluated with the other evidence in the matter.
Vehicle Accident Data and Pre-Crash Operation
Depending on the vehicle, available EDR information may preserve speed, braking, accelerator input, steering, or stability-control activity from a short interval before impact.
Those recorded values can be compared with driver statements, photographs, damage, and other evidence when evaluating the reported sequence of events.
Vehicle Accident Data and Multiple Events
Some supported vehicles may preserve more than one event record, particularly in a multi-impact accident or when another qualifying event occurred before or after the loss under review.
Event status, timing, pre-crash values, delta-V, restraint information, and other recorded parameters may help distinguish the available records and determine which event most reasonably corresponds with the accident being investigated.
Vehicle Accident Data Limitations
An EDR report may show that a particular parameter was not recorded, that an impact did not meet a required recording threshold, or that the available interval does not answer the disputed question.
Identifying those limitations is part of an objective evaluation and helps prevent the recorded information from being overstated.
