A department of transportation (DOT or DoT) is a government agency responsible for managing transportation. The term is primarily used in the United States to describe a transportation authority that coordinates or oversees transportation-related matters within its jurisdiction.

In the United States, the largest DOT is the United States Department of Transportation, a federal agency which oversees interstate travel and numerous other transportation agencies.^[1]

All U.S. states have their own DOTs, responsible for managing and overseeing transportation, transportation-related infrastructure, and transportation safety in their respective states. They provide enforcement through DOT officers within their respective jurisdictions.
