EDR and What it Means

What is EDR?

EDR is the acronym for “Event Data Recorder.” An Event Data Recorder (EDR) is a function or device installed in a motor vehicle to record technical vehicle and occupant information for a very brief period of time before, during, and after a crash.

Vehicle crash data is data that may be stored in the vehicle’s safety system after a crash. It is one of the most important pieces of evidence to be collected and evaluated as part of a vehicle crash investigation. The crash data is unbiased, proven, accurate and defensible. When examined along with other available physical evidence from the crash, the vehicle crash data can provide a much clearer understanding of what happened before, during and after the crash. 

After a vehicle module’s primary functions are complete, and where appropriate thresholds are met, data may be recorded as part of the “Event Data Recorder” (EDR) functionality or capability. An “EDR” is not a stand alone device and the data may not always be recorded.

Introduction Video on EDR Data

This video provides an overview of a vehicle’s event data recorder, sometimes referred to as the “black box” of an automobile. We’ll discuss the types of crash data that are available in these systems, the EDR tools and methods used to retrieve or “download” the crash data, and also how the crash data is used and who uses it.
