Item 7.01 Regulation FD Disclosure

     On December 20, 2004, Ryder System, Inc. (the “Company”) issued a press release relating to its 2005 business plan (the “Press Release”). The Company also hosted a conference call and webcast on December 20, 2004 during which a presentation was made on the Company’s 2005 business plan (the “Presentation”). The Press Release and the Presentation are available on the Company’s website.

     The Press Release and the Presentation include information regarding the Company’s 2004 earnings per share excluding gain on headquarters sale and 2004 net earnings excluding gain on headquarters sale which are non-GAAP financial measures as defined by SEC regulations. The Company believes that these non-GAAP financial measures provide useful information to investors as the measures exclude from the Company’s GAAP earnings a one-time gain unrelated to the Company’s ongoing business operations.

     The information in this Report, including Exhibits 99.1 and 99.2, are being furnished pursuant to Item 7.01 of Form 8-K and General Instruction B.2 thereunder.
