Mainly formal. SDDOT usually makes a report to the Senate and House Transportation Committees at the beginning of each legislative session regarding the state's highway needs and funding to meet those needs. A process exists by which standing committees will introduce legislation at the request of SDDOT. SDDOT monitors legislative committees and tracks bills of interest. SDDOT officials testify about bills that the agency supports or opposes. SDDOT has no dedicated legislative liaison; its Legal Office assists in formulating, drafting and monitoring legislation that affects the department.
