After a truck crash, one of the most critical pieces of evidence can be found inside the truck’s electronic control module, commonly referred to as the “black box.” Just like the black boxes in airplanes, these event data recorders safeguard potentially consequential data that can help reconstruct how the crash in question occurred.
For victims of truck accidents, this data can be key to uncovering the truth and building a strong personal injury case.
What happened, when and why?
Most modern commercial trucks are equipped with black boxes or similar systems that record important details about the vehicle’s operation before, during and after a crash. This includes data such as speed, brake usage, engine throttle position, GPS location, steering input, seatbelt status and whether the truck was accelerating or decelerating at the time of impact. In some cases, the device may also capture communications between the truck and dispatch centers.
This information can be incredibly valuable when it comes to determining fault. For example, if a trucking company claims that its driver was obeying the speed limit or that weather was to blame, the truck’s black box may reveal a different story—such as excessive speed, hard braking or last-minute evasive maneuvers that suggest driver error or distraction. The data can also highlight any problems with the vehicle, like brake failure or overdue maintenance.
Note, however, that this information can be lost or overwritten if not retrieved quickly. Trucking companies often control access to black boxes, and without legal intervention, they may delay or even destroy the data. That’s just one of the many reasons why it is important for injury victims or their families to seek personalized legal guidance and support as soon as possible after a crash.
