When an Absence of Evidence is Evidence! In moderate and high-speed collisions it is well known that Event Data Recorders, aka black boxes, record data that can provide valuable insight into the vehicle dynamics before and during the collision and assist experts in their accident reconstruction analyses.
Question: But what can the EDR tell us when a vehicle is involved in a low-speed accident and no data is recorded? Answer: The lack of data is data that can tell us something about the collision. Read More.
