Orland Park personal injury lawyerIf you have ever watched a news story about an airplane accident, you may have heard experts talking about the plane’s flight recorder or “black box.” Many commercial trucks are also equipped with a recording device which is often referred to as a black box. Technically called an event data recorder (EDR), this device can be an extremely valuable source of evidence in a truck accident injury case. Most personal injury claims hinge upon the question of fault and proving that the negligent actions of the truck driver, trucking company, or other party caused your truck accident is often the biggest obstacle in successfully obtaining compensation for injuries.

How Do EDRs Work?  

Most event data recorders are capable of recording vehicle and occupant information immediately before, during, and after a collision. Depending on the type of EDR installed, the device may record data about the vehicle’s engine performance, vehicle speed, whether or not the brakes were applied, steering performance, airbag deployment, seat belt usage, electronic stability control, and the force of the impact. Commercial trucking companies are not required to install EDRs in their trucks; however, more and more trucking companies are voluntarily installing these black boxes. After a truck accident, a data-retrieval technician may be able to extract data from the EDR. Because many of these devices do not permanently retain data, it is important to retrieve EDR information as soon as possible after an accident.

Proving Liability for a Truck Accident

The information contained in an EDR may be combined with other types of evidence and used to establish exactly what happened during an accident. Evidence from dash camera footage, security camera footage, the truck driver’s hours of service logs, the driver’s driving history, and the truck maintenance records may also shed light on how and why a truck accident occurred. Data from the truck driver’s personal cell phone may reveal whether or not distracted driving was a contributing factor in the accident. However, gaining access to this information is not easy. Trucking companies are usually very hesitant to release EDR data and other information and may even destroy data in an attempt to evade responsibility for an accident. An experienced truck accident lawyer can help ensure that this valuable evidence is preserved.
