Abstract The objective of this study was to reduce and analyze data from previously collected heavy-vehicle naturalistic data to better understand crashes involving heavy-vehicle drivers and the efficiency of Commercial Motor Vehicle (CMV) operations. Two key elements of this study were to investigate driver distraction and the role it plays in CMV operations and to answer critical questions related to hours of service (HOS) regulations and fatigue. More than 3.8 million miles of naturalistic data were collected from seven fleets and 10 locations under the original Onboard Monitoring System Field Operational Test (OBMS FOT) study. A total of 43 motorcoaches, 73 motorcoach drivers, 182 trucks and 172 truck drivers participated in this study. Key findings from the study showed an overall decrease in cell phone used compared to previous research. Hands-free cell phone use was found to be protective as it likely helps drivers alleviate boredom, while hand-held cell phone use was found to be risky as it takes the driver’s attention away from driving tasks. Additionally, the 8th driving hour showed the highest rate of safety critical event occurrence. This study provides needed insight into motorcoach and truck operations.
