The EDR data is inconsistent with the damage photos, measurements at the accident scene, and testimony of witnesses.

Expert testimony concerning the calibration and/ or maintenance of the vehicle.

The EDR was not in proper working condition and accurately recording information at the time of the accident.

In other cases, we have been unable to get data from an EDR that was burned beyond usefulness or had been left in an “off” position by the company.Įither party may challenge the admission of the EDR into evidence for the following reasons: In one of our recent cases a tractor trailer t-boned a passenger car, killing both people inside, but nothing of that incident was recorded on the truck’s EDR. They are not completely reliable, and may sometimes misread speed, air bag deployment, and seat belt use. However, an EDR cannot be used in all crash situations. The NHTSA released a statement on their website saying “EDRs can have a major impact on highway safety, assisting in real-world data collection to better define the auto safety problem, aiding in law enforcement, and understanding the specific aspects of a crash.”ĮDR data can serve as powerful evidence in motor vehicle crash cases where liability is in question. These new regulations could make it easier for investigators to figure out important information that led up to the event. Light vehicles include passenger cars, multipurpose passenger vehicles, trucks, and buses with a gross vehicle weight of 8,500 pounds or less. The National Highway Traffic Safety Administration (NHTSA) proposed rules last December that would make it mandatory for all light vehicles manufactured after Septemto have event data recorders (EDRs) installed. More sophisticated modules, such as on newer large trucks, records a variety of other operational data. The recorded data includes pre-crash and crash data, which is saved and may never be overridden. Second, in a deployment event, the air bags are deployed. First, a non-deployment event records data, but does not deploy the air bags-it contains pre-crash and crash data however, after 250 ignition cycles, the data is wiped out. There are two primary types of recorded crash events. When I attend vehicle inspections, often with the experts for both sides, they downloading data from a microchip onto a laptop computer by connecting a wire to a plug under the car’s dashboard, which will then generate reports for use in accident reconstruction. It is important to employ an accident reconstructionist who both has and is trained in the specific EDR / ECM system software. Different manufacturers use different software, some of which is proprietary and tightly controlled by the manufacturer. Typically, EDRs are located under the passenger front seat, driver’s seat, or the center console of a vehicle. This information can be downloaded from the EDRs memory to help crash investigators, police, and others understand what happened in the vehicle, how a vehicle’s safety systems performed, and sometimes even responsibility in the crash. The information that is gathered from the EDR or ECM may include a vehicle’s speed and acceleration, whether air bags were deployed, if breaks were applied and if seat belts were worn. Still fewer realize that failure to preserve data after a crash can have devastating effects in a serious personal injury case.Īn event data recorder (EDR) or electronic control module (ECM), typically referred to as the “black box”, is a device installed in a motor vehicle to record technical vehicle and occupant information for a brief period of time before, during, and after a crash.Īlthough this information typically is read for seconds, those seconds worth of data can be vital in winning and losing a case.

What many drivers fail to realize is that cars and trucks also records significant amounts of data that can either help or hurt them in their personal injury case.

Most people have heard that after plane crashes, investigators look for the “black box” data recorder of the plane to figure out what caused the crash. Our work in automobile accident lawsuits has been made more complex, and to some extent more subject to accurate proof, by the proliferation of “black boxes” recording computer data of some sort in virtually every late model vehicle on the road.
