Car black box what does it record

Furthermore, a car's black box does not record any audio such as in the case of the aircraft's CVR. While the automotive black box does not record as much data as the aircraft black box, it is still capable of recording an abundance of data.

Car black boxes were originally created to determine the cause of airbags’ activation but they collect several data of the driver’s actions including the speed which has made them very useful for reconstruction of accidents. In fact, the data recorded by car black boxes has been already used as an important evidence in the courts.

The black box typically records 5 to 10 seconds before the collision. There is also another type of car black boxes, also known as video data event recorder which are used by the drivers voluntarily.
