By statute, certain Federal officials are authorized home-to-work transportation, as are employees who meet certain statutory criteria as determined by their agency head. The Federal officials authorized by statute are the President, the Vice-President, and other principal Federal officials and their designees, as provided in 31 U.S.C. § 1344(b)(1) through (b)(7). Those employees engaged in field work, or faced with a clear and present danger, an emergency, or a compelling operational consideration may be authorized home-to-work transportation as determined by their agency head. No other employees are authorized home-to-work transportation.
