Department of Transportation
Federal highway authority
The Department of Transportation is a U.S. federal agency overseeing transportation systems—highways, railroads, aviation, maritime shipping, and pipelines.
Often abbreviated DOT, it regulates safety standards, funds infrastructure projects, and coordinates national transportation policy.
State-level departments of transportation handle local roads and transit: The DOT is repaving the interstate this summer.
