Alliance for Safe, Efficient, and Competitive Truck Transportation Sponsors Study of FMCSA Data; Findings Prove Published SMS BASIC Scores Lack Correlation to Crashes and Suffer from Numerous Statistical Flaws
The Alliance for Safe, Efficient, and Competitive Truck Transportation (ASECTT) commissioned a study by a Dr. James Gimpel professor at the University of Maryland with a Ph.D. from the University of Chicago. Dr. Gimpel served as the editor of American Politics Research from 2003 to 2011 and is the author of numerous books and peer-reviewed articles. Dr. Gimpel performed a detailed study of the statistical soundness of the SMS methodology and the correlation between individual carrier percentile rankings and crash frequency based upon data obtained from the Federal Motor Carrier Safety Administration.
