Accident Data Recorder (ADR)

In Simple Terms

Every F1 car must have an Accident Data Recorder (ADR) that captures crucial telemetry and sensor data during races. This black box device helps FIA stewards investigate incidents by providing objective evidence of what happened, including speed, throttle position, brake pressure, and steering inputs at the moment of any accident or collision.

• All cars must be fitted with a mandatory Accident Data Recorder to record real-time performance and sensor data
• ADR data is used by stewards to objectively investigate incidents, collisions, and accidents during races
• The device captures critical information like speed, throttle, brake pressure, and steering angle at the time of incidents
• Teams must ensure the ADR is functioning properly; failures to comply with ADR regulations can result in penalties
