Crash Risks by Commercial Motor Vehicle (CMV) Driver Schedules (Crash Risks)

The Federal Motor Carrier Safety Administration (FMCSA) is an operating administration within the U.S. Department of Transportation (DOT) with the mission to reduce commercial motor vehicle-related crashes and fatalities. To further this mission, FMCSA is authorized to conduct research under 49 U.S.C. 31108 Motor Carrier Research and Technology programs, and under section 31108(a)(3)(A-B), FMCSA may fund research, development, and technology projects related to (A) the causes of Safety Critical event (SCEs), injuries, and fatalities involving commercial motor vehicles and (B) means of reducing the number and severity of SCEs, injuries, and fatalities involving commercial motor vehicles. This information collection supports the DOT Strategic Goal of Safety. This research requires data to be collected for hours of service (HOS) duty logs, crash and incident data, and inspection violations records. As part of this effort, Pulsar Informatics, Inc. (Pulsar), under contract to FMCSA, will collect the data necessary to address the study objectives and research questions. The information collected will be used to examine the relative risk of crashes and inspection violations based on various factors related to the driver’s work schedule and demographics. This Privacy Impact Assessment (PIA) is being conducted to address the risks associated with Pulsar collecting, processing, and maintaining Personally Identifiable Information (PII) within each set of data collected on behalf of FMCSA.

DOT is committed to ensuring that information is available in appropriate alternative formats to meet the requirements of persons who have a disability. If you require an alternative version of files provided on this page, please contact privacy@dot.gov.
