Heavy Truck Event Data Recorder
Data in trucks require extra steps to ensure the data contained in the event data recorder is preserved. When the truck is not moved properly from the collision scene possible data spoliation exist. The data available in the truck could be up to a minute prior to the collision. The information contained in the event data recorder will aid in the investigation of the collision.
Passenger Car Event Data Recorder
Passenger car event data recorders are present in vehicles with airbags. Not all vehicles have a public tool access to that data. Data from a vehicle can answer questions concerning the collision from possible injuries suspected, unknown driver, to vehicle location prior to the collision. An airbag deployment is not required to set an event, but that data can be obtained.
