Doing so promptly helps us secure evidence \u2014 including black box data \u2014 for a potential truck accident claim.What Is a Black Box in Trucks?The term \u201cblack box\u201d refers to the event data recorder (EDR), a device installed in many 18-wheelers, semis, and other commercial trucks to record information about the vehicle\u2019s operation and the driver\u2019s actions moments before, during, and after a collision occurs. It is part of the engine\u2019s electronic control module (ECM)\u00a0on most commercial vehicles.The ECM controls and monitors various engine functions, such as fuel injection, ignition timing, and emissions. When engine functions fail, the ECM stores error codes that help mechanics diagnose and fix problems.The EDR component of the ECM monitors and records data about multiple functions. For example, if a reduction in wheel speed is sensed, the EDR can record almost two minutes of data about vehicle speed, brake application, clutch application, and cruise control status.Most but not all commercial trucks have EDRs. The Federal Motor Carrier Safety Administration (FMCSA), which regulates the U.S. trucking industry, does not require EDRs on commercial trucks.The FMCSA does require commercial trucks to install electronic logging devices (ELDs), which some people lump into what they consider a black box in commercial trucks. The ELD tracks drivers\u2019 hours of service (HOS) behind the wheel and other information, such as:The duration of engine useWhen the vehicle movesHow many miles the truck travelsMost late-model passenger vehicles have EDRs, which also can be accessed for their data after a crash.Data recorded by a black box EDR or ELD can be downloaded later by linking the EDR or ELD with appropriate software. Accessing EDR and ELD data from a commercial truck can be crucial when investigating the cause of a truck accident and performing a comprehensive\u00a0accident reconstruction.In many cases, David Blackwell Law must ask the court to order a crashed truck\u2019s EDR and ELD preserved and for the trucking company to allow our expert to download EDR and ELD data for our truck accident investigation. This makes it important to contact a truck accident lawyer before the crashed truck\u2019s owners have it repaired, junked, sold, etc., and this data is gone forever.What Kind of Data Does a Truck\u2019s Black Box Record?The event data recorder and electronic logging device in a commercial truck\u00a0can record over 100 different types of data about the truck\u2019s operation and the truck driver\u2019s activity. This includes data pertaining to:Date and timeWheel speedEngine RPMThrottle positionGear selectionDelta-V (a measurement of the effort required to change the direction of the truck at a specified speed)Anti-lock braking system statusYaw rateRoll angleLongitudinal accelerationLateral accelerationClutch statusService brake statusSeat belt statusTire pressureCruise control statusAccelerator governorCruise governorAudit trailEngine usage historyMaintenance historyFault codes (engine problems identified)Engine parametersCritical event data, i.e., rapid deceleration, swerving, hard braking.Legal Implications of Black Box DataData gathered from a crashed truck\u2019s event data recorder and\/or electronic logging device is\u00a0generally considered admissible evidence in court proceedings pertaining to truck accident claims. It may also be used outside of court in settlement negotiations with defendants\u2019 insurance companies.In a truck accident claim, your attorney will work to demonstrate that the accident that injured you was caused by negligence on the part of the truck driver and\/or another party responsible for the driver (i.e., their employer) or the truck\u2019s operations. By far, most commercial truck accidents are caused by driver error.Data from a black box in semi-trucks is solid, incontrovertible information. For example, black box data would clearly show excessive vehicle and engine speed followed by hard braking and swerving, all typical in a crash caused by speeding. If data showed no braking, no swerving, no let-up on the throttle, and no downshifting just before a crash, we would argue that the truck driver was likely drowsy, fatigued, or asleep when the accident occurred. Records of the driver\u2019s hours on the road would also contribute to the theory that fatigue contributed to the accident.Black box data might indicate one or more mechanical malfunctions, such as brake failure, which may have caused or contributed to the accident. This might give us reason to pursue a third-party claim against a service vendor responsible for maintaining the truck.Data from a truck\u2019s EDR and ELD provides an accurate and fairly measured assessment of the events leading up to the crash under scrutiny. These devices are more precise, detailed, and dependable than anything a witness to the crash can provide. In a courtroom, this data can challenge or support\u00a0either side\u2019s version of events.Truck accidents are often complicated, with multiple parties potentially liable for losses suffered by the injured. If a truck\u2019s black box data is intact after an accident, its contents can be crucial for understanding how the accident occurred. After a truck accident, the value of acting quickly to obtain black box data cannot be overstated.Contact Our Truck Accident Attorneys for HelpWere you hurt in an accident with a big rig in South Carolina?
