What the U.S. Secretary of Transportation does

This role oversees aviation, highways, rail, transit, maritime, pipelines, and safety regulation. The secretary prioritizes investments, sets regulatory frameworks, manages budgets, and coordinates with state, local, and tribal partners.

As a cabinet member, the secretary advises the president and represents the United States in international transportation agreements and forums.
Key responsibilities and portfolio areas
The secretary’s duties span policy, operations, funding, and oversight. Core responsibilities include advancing safety across modes, modernizing infrastructure, enforcing civil rights in transportation, and responding to emergencies. The role requires balancing national goals with regional needs while managing large grant programs and long-range planning.
Policy and planning
The office sets national transportation policy through multiyear legislation, executive orders, and strategic plans. Key inputs include the FAST Act and the Infrastructure Investment and Jobs Act, which guide investment in roads, bridges, transit, ports, and broadband connectivity within transportation systems.
Safety and regulation
The secretary works with the Federal Aviation Administration (FAA), the Federal Highway Administration (FHWA), the Federal Railroad Administration (FRA), the Pipeline and Hazardous Materials Safety Administration (PHMSA), and the National Highway Traffic Safety Administration (NHTSA) to set and enforce standards for vehicles, infrastructure, and operations. This includes aviation certification, motor carrier safety, and hazardous materials transportation.
Funding and grants

Programs include Federal-Aid Highway Funds, Transit Grants, the Airport Improvement Program, and emerging initiatives to expand broadband and resilience investments. The secretary oversees appropriation execution and prioritizes projects under funding frameworks.
Typical qualifications and expectations
While the U.S. Constitution and statute do not specify rigid educational requirements, nominees typically have relevant executive or legislative experience, demonstrated leadership, and deep policy knowledge in transportation, infrastructure finance, or public administration. Many have backgrounds as former governors, members of Congress, senior agency officials, or experts in logistics, engineering, or public policy. Senate confirmation is required, and nominees undergo rigorous review of their experience, judgment, and commitment to public service standards.
