Most commercial trucks are equipped with an Electronic Control Module (ECM) or Event Data Recorder (EDR), commonly referred to as a "black box." These systems can record valuable information about the truck's operation before, during, and after a crash.
Black box data may reveal:
- Vehicle speed
- Brake application
- Steering inputs
- Engine performance
- Hours driven
- Sudden acceleration or deceleration
- Seatbelt usage in some cases
This information can provide an objective record of what happened and may help determine whether the truck driver or trucking company acted negligently. In many truck accident cases, black box data becomes one of the most important pieces of evidence. Because this information can sometimes be overwritten or lost, it is often critical to act quickly to preserve it.
