Truck accidents can be debilitating for everybody involved. But it can also be hard to determine fault in an accident involving such a large vehicle. Sometimes pictures of the scene alone cannot tell the story of what happened to cause an accident. Black box data can be helpful to the case.
You might be familiar with black box data from airplanes that aid in piecing together what caused a crash. Eighteen-wheelers have them as well for similar reasons. In a commercial truck accident, black box data is used to figure out what happened and prove who was at fault for the collision.
