The Professional Truck Driver Institute (PTDI) is a non-profit organization that provides certification of training courses for drivers of commercial motor vehicles. It was formed in 1986 during the standardization of commercial driver's licensing by the Federal Motor Carrier Safety Administration in the United States. Its management was taken over by the TCA in 1996. PTDI is the first nonprofit organization to develop uniform skill performance, curriculum, and certification standards for the trucking industry and to award course certification to entry-level truck driver training courses and motor carrier driver-finishing programs.
