Abstract
This synthesis will be useful to federal and state agencies, commercial truck and bus operators, and others interested in improving commercial vehicle safety. The synthesis documents current information on existing commercial motor vehicle safety certification, selfevaluation, benchmarking, and best practices programs; identifies major common elements and protocols; and critically assesses evidence for the crash-reduction effectiveness of the programs. It includes a survey of truck carriers and other applicable industries and relevant organizations for their experiences. A literature review and case studies of innovative and successful practices are also included. (Author/publisher)
