The ADR2 is MoTeC's second generation Accident Data Recorder. It records critical data from vehicle accidents, such as lateral, longitudinal and vertical accelerations. This data can help to better understand forces in high impact collisions and may assist with the medical assessment of drivers.

The ADR2 captures minimum 30 seconds of data per event, including 15 seconds immediately before the accident which triggered recording. Subsequent impacts extend the event recording time.

The device can be used stand-alone or in conjunction with other devices such as a GPS, Display Logger or ECU.

The MoTeC ADR2 conforms to FIA standard 8872-2018 and is included in the FIA ADR Program.


The ADR2 Manager application requires Windows 10, 64 bit.
