EVENT DATA RECORDER

Black Box
Examination

An event Data Recorder is a device installed in motor vehicles to record technical vehicle and occupant information for a period of time. These devices are then downloaded by a professional reconstructionist who analyzes the data to determine important factors that led to the crash or fatality. Some EDRs continuously record data, overwriting the previous minutes until a crash is sensed. Others require some kind of crash-like event and will stop once the accident is over or time has expired.

Our team is professionally trained and knowledgeable when it comes to downloading, interpreting, and modeling the data from these downloads.
