What is the purpose of the Federal Transit Administration?

Answer: B — Improving bus and rail services

The purpose of the Federal Transit Administration (FTA) is primarily focused on improving bus and rail services across the United States. This agency plays a critical role in providing financial assistance and support for public transportation systems, helping to enhance the quality, accessibility, and efficiency of these services. By funding projects, promoting transit services, and establishing standards, the FTA aims to ensure that public transportation meets the needs of the community and fosters better mobility for its users. The other options involve areas that the FTA does not primarily address. Regulation of interstate commerce falls under the jurisdiction of the Department of Transportation and other agencies. While vehicle safety standards are established by the National Highway Traffic Safety Administration, the FTA itself is more involved in public transport systems than in developing safety protocols for vehicles. Finally, managing highway funds is typically the responsibility of the Federal Highway Administration, which oversees road infrastructure rather than public transit systems. Thus, the focus on improving bus and rail services distinctly aligns with the mission and activities of the FTA.
