FMCSA Complaint Center

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 established the FMCSA Complaint Center (formerly the National Consumer Complaint Database ─ NCCDB) to receive and manage filer complaints of alleged violations of commercial motor vehicle regulations. The FMCSA Complaint Center allows FMCSA to identify problematic motor carriers to take necessary enforcement actions and promote compliance with FMCSA regulations. FMCSA previously published a Privacy Impact Assessment (PIA) in accordance with the E-Government Act of 2002 to address the privacy risks associated with the FMCSA Complaint Center system and its collection and use of Personally Identifiable Information (PII). FMCSA is updating the PIA to reflect changes to the system that include a system name change from National Consumer Complaint Database (NCCDB) to FMCSA Complaint Center, an update to the system of records notice (SORN), and expanded system functionality such as new complaint categories and a public company complaint search feature.
