Which agency is responsible for enforcing HOS regulations?

The Department of Transportation (DOT) is the agency responsible for enforcing Hours of Service (HOS) regulations, which govern the maximum amount of time commercial drivers are allowed to be on duty, including driving and non-driving tasks. These regulations are crucial for ensuring safety on the roads, as they help to prevent driver fatigue, which can significantly increase the risk of accidents.

The DOT, through its Federal Motor Carrier Safety Administration (FMCSA), develops and enforces these regulations, conducting inspections and monitoring compliance among trucking companies and drivers. This oversight is vital for maintaining road safety standards and protecting both drivers and the public.

The other agencies listed do not have authority over HOS regulations. The Department of Labor focuses on workforce regulations and labor rights, the Environmental Protection Agency deals with environmental issues, and the Federal Bureau of Investigation is concerned with national security and federal law enforcement, making the Department of Transportation the appropriate authority for HOS enforcement.
