What is the main job of the Dept of Transportation?

• A. Run and regulate all air, water, rail, and road transportation
• B. Manage the national budget
• C. Oversee energy policy
• D. Administer social welfare programs

Answer: (A)

The main job of the Department of Transportation is to oversee and regulate transportation across all modes—air, water, rail, and road—to keep people and goods moving safely and efficiently. This broad federal role includes setting safety standards, enforcing regulations, and funding and guiding national transportation infrastructure and policies through agencies like the FAA, US Coast Guard, Federal Railroad Administration, and others. In short, it coordinates and monitors transportation systems across multiple modes, not just one sector.

Other options describe tasks that belong to different parts of government. Managing the national budget is handled by agencies like the Office of Management and Budget and the Treasury, overseeing energy policy is the realm of the Department of Energy, and administering social welfare programs is the responsibility of other social-service departments.
