Which federal agency governs the interstate standards for commercial driving?

The Federal Motor Carrier Safety Administration (FMCSA) governs the interstate standards for commercial driving. This agency is responsible for regulating the safety of commercial motor vehicles and ensuring that both drivers and companies comply with federal regulations related to driver licensing, vehicle safety, and operational standards. The FMCSA sets forth the guidelines that must be adhered to for interstate commerce, including hours of service, vehicle maintenance, and training requirements for commercial drivers.

This emphasis on safety and regulatory compliance is crucial for maintaining standards that ensure the safe operation of commercial vehicles which operate across state lines. The agency's initiatives include implementing regulations that reduce the number of accidents and enhance safe driving practices among commercial drivers.

Other agencies have different focuses; for instance, the National Highway Traffic Safety Administration is primarily concerned with vehicle safety and consumer protection related to automobile safety, the Transportation Security Administration deals with security in the transportation system, particularly for aviation, and the Federal Aviation Administration focuses exclusively on civil aviation safety. Each agency plays an important role in its respective area, but the FMCSA is specifically designated to handle the standards for commercial driving on highways across state boundaries.
