EDR Imaging & Analysis

Event Data Recorder (EDR) data is a valuable resource that has been successfully admitted in many civil and criminal proceedings. The data generally requires expert testimony to validate and/or interpret it.

What is an EDR?

An Event Data Recorder (EDR) is a function or device installed in a motor vehicle to record technical vehicle and occupant information for a brief period of time (seconds) before, during and after a crash for the purpose of monitoring and assessing vehicle safety system performance.

The EDR function is typically located inside a vehicle’s airbag control module (ACM) and is capable of recording such information as:

• vehicle’s indicated speed
• brake pedal usage
• accelerator pedal input
• steering wheel input
• seatbelt status
• airbag deployment information
• severity of the crash
• and a multitude of other inputs and status information

Throughout the world, EDR readout tools are used for the retrieval of data from EDR’s to assist with the investigations of motor vehicle accidents.

Which vehicles are equipped with an EDR?

Millions of passenger cars and light trucks on the road today, world-wide, are equipped with an EDR. In the United States and Canada alone, more than 200 million registered vehicles are equipped and approximately 98% of new vehicles sold in the US and Canada have an EDR.

What are some uses of EDR data?

EDR data is used today for vehicle crash research, accident investigation & reconstruction, product liability litigation, safety system field performance analysis and insurance claims.
