COMMERCIAL TRUCK AND BUS SAFETY SYNTHESIS PROGRAM Safety is a principal focus of government agencies and private-sector organiza- tions concerned with transportation. The Federal Motor Carrier Safety Admin- istration (FMCSA) was established within the Department of Transportation on January 1, 2000, pursuant to the Motor Carrier Safety Improvement Act of 1999. Formerly a part of the Federal Highway Administration, the FMCSAâs primary mission is to prevent commercial motor vehicle-related fatalities and injuries. Administration activities contribute to ensuring safety in motor carrier operations through strong enforcement of safety regulations, targeting high-risk carriers and commercial motor vehicle drivers; improving safety information systems and commercial motor vehicle technologies; strengthening commercial motor vehicle equipment and operating standards; and increasing safety aware- ness. To accomplish these activities, the Administration works with federal, state, and local enforcement agencies, the motor carrier industry, labor, safety interest groups, and others. In addition to safety, security-related issues are also receiving significant attention in light of the terrorist events of September 11, 2001. Administrators, commercial truck and bus carriers, government regulators, and researchers often face problems for which information already exists, either in documented form or as undocumented experience and practice. This informa- tion may be fragmented, scattered, and underevaluated. As a consequence, full knowledge of what has been learned about a problem may not be brought to bear on its solution. Costly research findings may go unused, valuable experience may be overlooked, and due consideration may not be given to recommended practices for solving or alleviating the problem. There is information available on nearly every subject of concern to com- mercial truck and bus safety. Much of it derives from research or from the work of practitioners faced with problems in their day-to-day work. To provide a systematic means for assembling and evaluating such useful information and to make it available to the commercial truck and bus industry, the Commercial Truck and Bus Safety Synthesis Program (CTBSSP) was established by the FMCSA to undertake a series of studies to search out and synthesize useful knowledge from all available sources and to prepare documented reports on current practices in the subject areas of concern. Reports from this endeavor constitute the CTBSSP Synthesis series, which collects and assembles the vari- ous forms of information into single concise documents pertaining to specific commercial truck and bus safety problems or sets of closely related problems The CTBSSP, administered by the Transportation Research Board, began in early 2002 in support of the FMCSAâs safety research programs. The pro- gram initiates three to four synthesis studies annually that address concerns in the area of commercial truck and bus safety. A synthesis report is a document that summarizes existing practice in a specific technical area based typically on a literature search and a survey of relevant organizations (e.g., state DOTs, enforcement agencies, commercial truck and bus companies, or other organiza- tions appropriate for the specific topic). The primary users of the syntheses are practitioners who work on issues or problems using diverse approaches in their individual settings. The program is modeled after the successful synthesis pro- grams currently operated as part of the National Cooperative Highway Research Program (NCHRP) and the Transit Cooperative Research Program (TCRP). This synthesis series reports on various practices, making recommendations where appropriate. Each document is a compendium of the best knowledge available on measures found to be successful in resolving specific problems. To develop these syntheses in a comprehensive manner and to ensure inclu- sion of significant knowledge, available information assembled from numerous sources, including a large number of relevant organizations, is analyzed. For each topic, the project objectives are (1) to locate and assemble docu- mented information (2) to learn what practice has been used for solving or alle- viating problems; (3) to identify all ongoing research; (4) to learn what problems remain largely unsolved; and (5) to organize, evaluate, and document the useful information that is acquired. Each synthesis is an immediately useful document that records practices that were acceptable within the limitations of the knowl- edge available at the time of its preparation. The CTBSSP is governed by a Program Oversight Panel consisting of indi- viduals knowledgeable in the area of commercial truck and bus safety from a number of perspectivesâcommercial truck and bus carriers, key industry trade associations, state regulatory agencies, safety organizations, academia, and related federal agencies. Major responsibilities of the panel are to (1) provide general oversight of the CTBSSP and its procedures, (2) annually select syn- thesis topics, (3) refine synthesis scopes, (4) select researchers to prepare each synthesis, (5) review products, and (6) make publication recommendations. Each year, potential synthesis topics are solicited through a broad industry- wide process. Based on the topics received, the Program Oversight Panel selects new synthesis topics based on the level of funding provided by the FMCSA. In late 2002, the Program Oversight Panel selected two task-order contractor teams through a competitive process to conduct syntheses for Fiscal Years 2003 through 2005.

On the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Ralph J. Cicerone is president of the National Academy of Sciences. The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Charles M. Vest is president of the National Academy of Engineering. The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the ser- vices of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, on its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine. The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academyâs purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Acad- emy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Ralph J. Cicerone and Dr. Charles M. Vest are chair and vice chair, respectively, of the National Research Council. The Transportation Research Board is one of six major divisions of the National Research Council. The mission of the Transportation Research Board is to provide leadership in transportation innovation and prog- ress through research and information exchange, conducted within a setting that is objective, interdisciplinary, and multimodal.

This report synthesizes current information on driver selection methods of commercial truck and bus companies, based primarily on the use of tests, measurements, and other assessments of applicants. It identifies and describes driver selection methods and instru- ments and their usefulness in predicting driver safety. The audience for this study includes motor carrier safety managers, other carrier executives and managers, and government and industry officials. The report reviewed the academic, commercial, and industrial literature on tests, mea- surements, and other procedures used by motor carriers to select safe commercial drivers. The study revealed large and enduring individual differences in crash risk among com- mercial drivers and highlighted the need for valid and usable driver selection procedures for carriers. Sources of this information were naturalistic driving studies, behavioral histories FOREWORD PREFACE By Donna L. Vlasak Senior Program Officer Transportation Research Board
(âbiodataâ), driving behavioral histories, and other human performance studies, as well as fed- eral regulations. Surveys and interviews were used to obtain information from motor carrier safety manag- ers and other experts on selection procedures and tests and on underlying driver characteristics relevant to risk. The project surveys of motor carrier safety managers and other experts on truck and bus safety were convenience samples of individuals active in national industry and research organizations. These individuals included professionals in government, industry trade asso- ciations, other industry roles (e.g., safety consulting), and research. These survey respondent groups of interested, knowledgeable individuals provided indications of industry thinking on safety management questions from two different perspectives. A select group of ten motor carrier safety managersâthose whose questionnaire responses indicated an active focus on driver assessmentâwere interviewed for case studies on driver selection practices. Each case study describes the companyâs driver selection methods and fea- tures innovative hiring and related human resources management practices. Ron Knipling, Safety for the Long Haul, Arlington, Virginia, Stephen V. Burks, Kristen M. Starner, Christopher P. Thorne, and Michael R. Barnes, University of Minnesota, Morris, and Gene Bergoffen, MaineWay Services, Fryeburg, Maine, collected and synthesized the informa- tion and wrote the report. The Commercial Truck and Bus Safety Synthesis Program Oversight Committee members are acknowledged on the preceding page. This synthesis is an immedi- ately useful document that records the practices that were acceptable within the limitations of the knowledge available at the time of its preparation.
