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.
The Federal Motor Carrier Safety Administration (FMCSA) implemented a rule significantly changing the Hours-of-Service (HOS) rules in July 2013. The impacts of these changes on commercial truck drivers and motor carriers is assessed in this report. The report closely follows the American Transportation Research Institute (ATRI) June 2013 publication, "Assessing the Impacts of the 34-Hour Restart Provisions" and quantifies operational and economic impacts since the July 2013 HOS rules went into effect. Two surveys were conducted by the ATRI Research Team for its analysis; a driver survey and a motor carrier survey. ATRI also conducted an analysis of logbook data from drivers. Survey results indicated that 12.4% of drivers with prior experience using the restart had discontinued use once the new rules went into effect. Respondents indicated that benefits of the restart have diminished, particularly those related to productivity. Most respondents indicated that the two new restart provisions have impacted their operations in a moderately or significantly negative way. Results also indicated that many drivers are adjusting to the new restart rules by changing schedules, incorporating a rolling schedule into their operations, changing start/end times and turning down loads.
