The study makesuse of a large data set from the U.S. Department of Transport (D.O.T.) State Traffic Accident Files and accounts for the general impactof seat belt laws as well as their dynamic effects on injury rates.The models adjust for a wide range of additional contributing factors to injury rates, including the influence of unemployment rates, speed limits, companion effects, and others.
