A commercial truck’s “black box,” often called an event data recorder (EDR) or electronic control module (ECM), is an electronic device that records certain operational information before, during, and after a collision.
Depending on the vehicle and manufacturer, this data may include vehicle speed, braking activity, throttle position, engine performance, seat belt status, and other information that may assist investigators in reconstructing how a truck accident occurred.
Not every commercial truck records the same information, and accessing this data often requires specialized equipment. Consult a North Carolina truck accident attorney to evaluate your case, preserve evidence, and strategize your next steps.
