Event Data Recorder (EDR)

According to the National Highway Traffic Safety Administration, 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, not minutes) before, during, and after a crash for the purpose of monitoring and assessing vehicle safety system performance.”

As your car is being driven, the EDR collects data such as speedometer readings and driver input while the vehicle is on. It normally keeps about 5 seconds’ worth of data. If the EDR detects a crash, it secures the data it has in place and starts monitoring the crash as it is happening to decide whether or not to deploy airbags.

Vehicle Event Data Recorder or EDR systems contain data regarding the vehicle’s operation just prior to a crash and compile data measured from sensors during a collision. It may record information such as pre-crash vehicle dynamics and system status, driver inputs, vehicle crash signature, restraint usage/deployment status, and post-crash data.

Most newer North American vehicles contain these EDR systems, which can help determine culpability and help you make informed and accurate decisions regarding your crash case.
