The Oregon Department of Transportation (ODOT) helps move people and goods across the state. The agency strives to provide a safe and efficient transportation system -- including highway, rail, and public transit -- for its residents. The department is responsible for construction and maintenance of highways and bridges, improving public transportation services, reducing traffic crashes, and ensuring equal access for low-income and elderly citizens, as well as people with disabilities. Its division of driver and motor vehicles (DMV) provides vehicle registration, driver licenses, and ID cards. The agency also tries to decrease the impact that its transportation system has on air and water quality.
