Summary
The *2016 Pocket Guide to Large Truck and Bus Statistics* is a statistical report published by the Federal Motor Carrier Safety Administration (FMCSA) to support its mission of reducing crashes, injuries, and fatalities involving large trucks and buses. The document compiles data-driven insights to inform safety regulations and enforcement strategies, balancing motor carrier safety with operational efficiency. It serves as a comprehensive reference for the state of the commercial motor vehicle (CMV) industry, utilizing data from the Motor Carrier Management Information System (MCMIS), the Fatality Analysis Reporting System (FARS), and other federal sources. The guide aggregates data from 2011 to 2015, with specific snapshots taken in late 2015 and early 2016. It covers seven primary areas: industry overview, roadside inspections, investigations, crashes, data quality, grant programs, and agency resources. The methodology relies on registration data, census files, inspection records collected by state and federal personnel, and investigation files. Key datasets include vehicle registration statistics from the Federal Highway Administration, driver licensing data, and observational surveys such as the Seat Belt Usage by Commercial Motor Vehicle Drivers (SBUCMVD) Survey. Key findings indicate that in 2014, there were approximately 10.9 million registered large trucks and 872,027 buses in the United States. Large trucks accounted for 9.2 percent of total vehicle miles traveled, while buses accounted for 0.5 percent. As of December 2015, there were 551,150 active interstate and intrastate hazardous materials carriers, employing approximately 6.0 million CMV drivers, of whom 3.1 million held Commercial Driver’s Licenses (CDLs) for interstate operations. Roadside inspection data from 2011–2015 shows a slight decline in total inspections, with driver out-of-service rates hovering around 4.9 percent and vehicle out-of-service rates near 20.3 percent. Safety belt usage among CMV drivers increased from 78.1 percent in 2010 to 83.7 percent in 2013. In 2014, there were 3,649 fatal crashes involving large trucks and buses. The significance of this report lies in its role as a foundational resource for evidence-based policy making within the FMCSA. By providing detailed metrics on carrier activity, inspection compliance, and crash outcomes, the guide enables regulators to identify safety trends and target enforcement efforts effectively. It highlights the scale of the regulated industry and the prevalence of safety violations, underscoring the necessity of continued monitoring and regulatory oversight to mitigate risks associated with commercial motor vehicle operations.
