Six of the seven members of the Commission of the Department of Transportation are elected to four-year terms by the legislators residing in each of the state's six congressional districts, and can be removed by the governor for cause (S.C Code Ann. §1-3-240). The seventh is an at-large member appointed by the governor who serves at the pleasure of the governor. Such elections or appointments must take into account race and gender so as to represent all segments of the state's population to the greatest extent possible. Candidates and appointees must be screened by the Joint Transportation Review Committee to determine whether they meet statutory requirements for education and experience. No legislator or legislator's immediate family member is eligible (S.C. Code Ann. §§57-1-310 et seq.). The secretary of transportation is appointed by the governor, with the advice and consent of the Senate and within statutory requirements for knowledge and ability, and serves at the pleasure of the governor (S.C. Code Ann. §57-1-410). The gubernatorial appointment of the secretary of transportation expires in 2015, at which time the responsibility reverts to the commission (2007 S.C. Acts, Act 114).
