Does my automobile have a black box installed? History reveals that in the early 1990's, auto makers from Cadillac, Chevrolet, Buick and Pontiac used the EDR as a method to understand how automobiles performed in accidents. Since 2000, the National Highway Traffic Security Administration (NHTSA) has gathered data including car mishaps also. Today every vehicle offered in the United States should have an EDR.
