The mission of the Federal Motor Carrier Safety Administration (FMCSA), an Operating Administration within the U.S. Department of Transportation (DOT), is to reduce crashes, injuries, and fatalities involving large trucks and buses (motor carriers). To carry out its safety mandate, FMCSA partners with stakeholders, including Federal, State, and local enforcement agencies; the motor carrier industry; safety groups; commercial motor vehicle (CMV) drivers; and organized labor on efforts to reduce crashes involving CMVs. Since the first step towards reducing crashes is to understand them, FMCSA collects and maintains Federal databases for motor carrier and CMV driver safety data as well as a national inventory of motor carriers and shippers subject to Federal Motor Carrier Safety Regulations (FMCSR) and Hazardous Materials Regulations (HMR).
Section 12007 of the Commercial Motor Vehicle Safety Act (CMVSA) of 1986 (Public Law 99-570, 100 Stat. 3207, October 27, 1986) and Title 49 of the U.S. Code, Section 31309, entitled Commercial driver's license information system require DOT to establish an information system which will serve as a clearinghouse and depository of information pertaining to the licensing and identification of operators of commercial motor vehicles and the disqualification of such. To comply with this mandate, FMCSA reviewed the options allowed under CMVSA. The conclusion was to assist the American Association of Motor Vehicle Administrators (AAMVA) and the State driver licensing agencies (SDLAs) to design and implement the State operated Commercial Driver's License Information System (CDLIS).
