Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block] | 1. Basis of Presentation References in this Report on Form 10-Q to "we," "us," "our," "Celadon," the "Company," or similar terms refer to Celadon Group, Inc. and its consolidated subsidiaries. All inter-company balances and transactions have been eliminated in consolidation. The accompanying condensed consolidated unaudited financial statements of Celadon Group, Inc. and its subsidiaries have been prepared in accordance with accounting principles generally accepted in the United States of America and Regulation S-X, instructions to Form 10-Q, and other relevant rules and regulations of the Securities and Exchange Commission (the "SEC"), as applicable to the preparation and presentation of interim financial information. Certain information and footnote disclosures have been omitted or condensed pursuant to such rules and regulations. We believe all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. Results of operations in interim periods are not necessarily indicative of results for a full year. These unaudited condensed consolidated financial statements and notes thereto should be read in conjunction with our consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended June 30, 2013. The preparation of the financial statements in conformity with United States generally accepted accounting principles ("GAAP") requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.
