TRB's Commercial Truck and Bus Safety Synthesis Program (CTBSSP) Synthesis 8: Commercial Motor Vehicle Driver Safety Belt Usage identifies and documents motivating factors that influence commercial motor vehicle (CMV) drivers in deciding whether to wear safety belts and research and practices that address CMV safety belt usage. It also offers a review of ergonomic and human engineering factors in the design and use of safety belts in CMVs as well as approaches to facilitate safety belt use by truck manufacturers.

TRB's Commercial Truck and Bus Safety Synthesis Program (CTBSSP) Synthesis 14: The Role of Safety Culture in Preventing Commercial Motor Vehicle Crashes explores practices on developing and enhancing a culture of safety among commercial motor vehicle drivers. The report also examines suggested steps for increasing a safety culture through a series of best practices.

Increasing seat belt use is one of the most effective and least costly ways of reducing the lives lost and injuries incurred on the nation's highways each year, yet about one in four drivers and front-seat passengers continues to ride unbuckled. The Transportation Research Board, in response to a congressional request for a study to examine the potential of in-vehicle technologies to increase belt use, formed a panel of 12 experts having expertise in the areas of automotive engineering, design, and regulation; traffic safety and injury prevention; human factors; survey research methods; economics; and technology education and consumer interest. This panel, named the Committee for the Safety Belt Technology Study, examined the potential benefits of technologies designed to increase belt use, determined how drivers view the acceptability of the technologies, and considered whether legislative or regulatory actions are necessary to enable their installation on passenger vehicles. The National Highway Traffic Safety Administration (NHTSA), the study sponsor, funded and conducted interviews and focus groups of samples of different belt user groups to learn more about the potential effectiveness and acceptability of technologies ranging from seat belt reminder systems to more aggressive interlock systems, and provided the information collected to the study committee. The committee also supplemented its expertise by holding its second meeting in Dearborn, Michigan, where it met in proprietary sessions with several of the major automobile manufacturers, a key supplier, and a small business inventor of a shifter interlock system to learn of planned new seat belt use technologies as well as about company data concerning their effectiveness and acceptability. The committee's findings and recommendations are presented in this five-chapter report.

Every year roughly 100,000 fatal and injury crashes occur in the United States involving large trucks and buses. The Federal Motor Carrier Safety Administration (FMCSA) in the U.S. Department of Transportation works to reduce crashes, injuries, and fatalities involving large trucks and buses. FMCSA uses information that is collected on the frequency of approximately 900 different violations of safety regulations discovered during (mainly) roadside inspections to assess motor carriers' compliance with Federal Motor Carrier Safety Regulations, as well as to evaluate their compliance in comparison with their peers. Through use of this information, FMCSA's Safety Measurement System (SMS) identifies carriers to receive its available interventions in order to reduce the risk of crashes across all carriers. Improving Motor Carrier Safety Measurement examines the effectiveness of the use of the percentile ranks produced by SMS for identifying high-risk carriers, and if not, what alternatives might be preferred. In addition, this report evaluates the accuracy and sufficiency of the data used by SMS, to assess whether other approaches to identifying unsafe carriers would identify high-risk carriers more effectively, and to reflect on how members of the public use the SMS and what effect making the SMS information public has had on reducing crashes.

Describes the basic research procedures used in the area of driving behavior and highway safety.

There are approximately 4,000 fatalities in crashes involving trucks and buses in the United States each year. Though estimates are wide-ranging, possibly 10 to 20 percent of these crashes might have involved fatigued drivers. The stresses associated with their particular jobs (irregular schedules, etc.) and the lifestyle that many truck and bus drivers lead, puts them at substantial risk for insufficient sleep and for developing short- and long-term health problems. Commercial Motor Vehicle Driver Fatigue, Long-Term Health and Highway Safety assesses the state of knowledge about the relationship of such factors as hours of driving, hours on duty, and periods of rest to the fatigue experienced by truck and bus drivers while driving and the implications for the safe operation of their vehicles. This report evaluates the relationship of these factors to drivers' health over the longer term, and identifies improvements in data and research methods that can lead to better understanding in both areas.
