Which agency is responsible for carrier safety oversight according to the Motor Carrier Safety Improvement Act of 1999?

The Federal Motor Carrier Safety Administration (FMCSA) is the agency primarily responsible for overseeing the safety of commercial motor carriers according to the Motor Carrier Safety Improvement Act of 1999. This act was designed to enhance the safety of motor carrier operations across the United States. The FMCSA implements and enforces regulations, provides oversight of compliance with safety standards, and initiates safety initiatives to reduce accidents and improve road safety. Their role also includes conducting inspections, issuing licenses, and managing programs that educate both carriers and drivers about safety regulations and best practices. This central focus on safety distinguishes the FMCSA from other agencies that might have different responsibilities, such as traffic safety, transportation infrastructure, or environmental regulations.
