Crash Data Retrieval (CDR)

Crash Data Retrieval (CDR) is a specialized technology used by law enforcement and investigators to access and analyze a vehicle’s digital data from the event of a collision. Modern vehicles contain sensors and computers that log information such as speed, brake application, seatbelt use, and airbag deployment during a crash. CDR tools connect to the vehicle’s communication systems to extract this data, providing valuable insights into the circumstances leading up to and during the crash. This information helps determine fault, improve vehicle safety, and support investigations.
