State Departments of Transportation (DOTs) are government agencies responsible for managing transportation infrastructure within a specific state. They are responsible for designing, building, and maintaining highways, roads, bridges, and other transportation infrastructure. State DOTs also oversee the licensing of drivers, registration of vehicles, and the enforcement of transportation safety regulations. Additionally, they work with local governments and transportation authorities to coordinate transportation planning and ensure efficient use of resources. The mission of State DOTs is to provide safe and reliable transportation systems that support economic growth, environmental sustainability, and social equity for all residents of the state.
