A3. A so-called “black box” is actually an event data recorder (“EDR”). EDRs can be simple or complex. Some collect only vehicle acceleration/deceleration data, while others collect data about driver inputs and vehicle systems status. Unlike the OBD II connector, EDRs are generally not accessible to the car owner and only collect data from a very short period of time, such as the preceding minute of the car’s operation.
