Peters joined the
Arizona Department of Transportation in 1985, and was appointed by Gov.
Jane Dee Hull to serve as its director in 1998. After
George W. Bush took office as president in 2001, Peters left for Washington to work as the Administrator of the
Federal Highway Administration. She worked in that capacity until 2005. She was also a speculated candidate for governor in 2010, but instead served as co-chair of incumbent governor
Jan Brewer's election campaign (along with former
state Attorney General Grant Woods). Peters is a transportation consultant for national engineering and planning organizations.
Transportation Secretary Joshua Bolten on October 17, 2006 On September 5, 2006, Bush nominated Peters to replace
Norman Mineta as Secretary of Transportation. She was confirmed on September 29, 2006 by the
United States Senate. In 2006, President Bush appointed Peters as the Co-Vice Chairwoman of the National Surface Transportation Policy and Revenue Study Commission. She resigned the post of Secretary of Transportation in anticipation of the in-coming Obama administration. She was succeeded by
Ray LaHood, the 16th U.S. Secretary of Transportation on Thursday, January 22, 2009.
Policies Peters is an advocate of leasing U.S. roads and interstates to private companies and having
user fees (i.e., tolls) for building new highways. In an interview, Peters said that the
National Highway System would run out of money by the end of the aughts without substantial changes and, rather than raise taxes, some states should turn to
toll roads leased to private corporations to fill gaps. Her policies of promoting open borders for commerce created opposition from labor unions. Mary Peters held a press conference on September 5, 2008 to report that Highway Trust Fund payments to states, including her native Arizona, would be cut back because federal fuel tax collections were dropping. While she was Secretary of DOT a rule was passed stating that dogs, cats, miniature horses, pigs as well as monkeys could be considered emotional support animals, and therefore could be taken by commercial airlines in the cabin. == Personal life ==
