An Event Data Recorder (\u201cEDR\u201d) is a device installed in commercial vehicles, light passenger cars, light trucks, and vans that captures information related to crashes. Sometimes mistakenly referred to as \u201cBlack Boxes,\u201d the United States Department of Transportation National Highway Traffic Safety Administration (\u201cNHTSA\u201d) uses the term \u201cEDR\u201d to refer to data recording devices that are installed on vehicles.\u00a0 \u201cBlack Boxes\u201d refer to the more sophisticated devices found on airplanes, trains and ships.[1]<\/a><\/p>\n

Although manufacturers are not required to install EDRs in light passenger vehicles, many manufacturers choose to do so[2]<\/a> because the devices collect real-world data to better define auto safety problems and to understand the specific aspects of a crash. It is estimated that about 64 percent of the 2005 model year passenger vehicles have some EDR capability.\u00a0 In 2014, it was estimated that 96 percent of all new cars sold in the United States were equipped with an EDR.[3]<\/a> Currently, NHTSA is considering whether to make EDRs mandatory in all new cars, light trucks and SUVs.<\/p>\n

What EDRs Can Tell Us<\/strong><\/p>\n

EDRs can provide a wide variety of data points, including speed, braking, steering, acceleration, seatbelt use, and, in the event of a crash, force of impact and whether or not the airbags were deployed. \u00a0Most EDRs record data in a continuous loop, writing over information again and again until a vehicle is involved in a crash. Then, EDRs automatically save up to 5 seconds of data from immediately before, during and after an incident.<\/p>\n

Determining Whether Your Vehicle Has an EDR<\/strong><\/p>\n

Starting in 2005, most vehicle manufacturers placed a statement in the owner\u2019s manual stating whether the vehicle has an EDR.\u00a0 At the national level, beginning with 2011 model year vehicles, manufacturers are required to state whether the vehicle has an EDR in the owner\u2019s manual.\u00a0 Virginia has required automobile manufacturers to disclose the existence of EDRs in the owner\u2019s manual since 2008.[4]\u00a0\u00a0<\/a>Click here for a list of vehicles with accessible data.<\/a><\/p>\n

Getting EDR Data<\/strong><\/p>\n

EDR data cannot be extracted or interpreted without an expert. \u00a0Extracting the data after an accident involves using special data-retrieval tool kits that consist of hardware, software and a cable that plugs into the vehicle\u2019s onboard diagnostics port. \u00a0Crash data retrieval tool kits can be expensive (running $2,000 – $10,000 or more).<\/p>\n

In Virginia, investigators from the Virginia Crash Reconstruction Team, a special team within the State Police, have the ability to access and extract EDR data.\u00a0 \u00a0 \u00a0\u00a0<\/strong><\/p>\n

Privacy Concerns<\/strong><\/p>\n

Civil liberty and privacy groups have raised concerns about the implications of EDRs spying on car users, particularly as the issue of who owns the data has not yet been fully resolved. \u00a0There has also been some controversy over the use of recorded data as evidence in court cases and for insurance claims against the driver of a crashed vehicle.\u00a0 Seventeen states including Virginia have enacted legislation regarding access to and the ownership of EDR data.<\/p>\n

In Virginia, EDR data can be retrieved under the following conditions:[5]<\/a><\/p>\n
