Which agency is responsible for federal highway policies in the US?

The Federal Highway Administration (FHWA) is the agency responsible for overseeing federal highway policies in the United States. This includes the administration of funding for highway construction and maintenance, setting standards for highway design and safety, and ensuring that projects adhere to federal regulations. The FHWA plays a crucial role in promoting safe, efficient, and sustainable transportation systems across the country. Its focus is not only on the highways themselves but also on the integration of various transportation modes, which is vital for national mobility.

In contrast, the Department of Transportation (DOT) serves as a broader umbrella organization that encompasses multiple transportation-related agencies, including the FHWA. While DOT has an overall responsibility for transportation policy, it does not specifically handle the day-to-day operations and regulations related to highway systems that the FHWA manages.

The Transportation Security Administration (TSA) is responsible for the security of the traveling public in air transportation, and the Environmental Protection Agency (EPA) focuses on environmental protection and regulations, neither of which directly involve federal highway policy. Therefore, the FHWA is the correct choice when identifying the specific agency dedicated to federal highway matters.
