Short Answer:
An EDR (Event Data Recorder), or “black box,” in a truck accident records critical data such as speed, braking, and driver actions before and during a crash. This information can be key evidence in proving fault. Learn more about preserving evidence here.
Example:
If a truck’s EDR shows the driver was speeding and failed to brake before impact, that data can support your claim and help establish liability against the trucking company or driver.
