Question 6636
What system records and stores relevant information to determine what happened before, during, and immediately after an accident?
- The event data recorder, or EDR.
- The driver availability monitoring system.
- The advanced driver distraction warning system.
Show answer and explanation
Correct answer: The event data recorder, or EDR.
The EDR, the car's black box, does this. It stores data such as speed, whether the brakes were applied, and airbag status from shortly before a crash until just afterward, to find out what happened in a crash like the one in the image. The distraction warning and availability monitor watch the driver while driving.
