Modern vehicles are equipped with Event Data Recorders (EDRs), commonly called “black boxes,” which capture key vehicle data during serious collisions. Standardized under NHTSA regulations in 49 CFR Part 563, these systems record a brief snapshot of information before, during, and after a crash rather than continuously monitoring drivers.
Depending on the manufacturer and model, an EDR may store details such as vehicle speed, engine RPM, throttle position, brake use, steering input, seat belt status, airbag deployment, and changes in vehicle velocity.
The recorded data helps engineers improve vehicle safety, supports crash investigators in reconstructing accidents, and can serve as important evidence in insurance claims and legal cases. Because many EDRs capture vehicle speed in the moments leading up to an impact, they provide valuable insight into the circumstances of a collision while focusing only on crash-related events instead of everyday driving.
