Basis of Presentation [Abstract]

Consolidation, Policy [Policy Text Block]

Basis of Presentation

The accompanying consolidated financial statements include the parent company, Heartland Express, Inc., and its subsidiaries, all of which are wholly owned. All material intercompany items and transactions have been eliminated in consolidation. The accompanying unaudited consolidated financial statements of Heartland Express, Inc. and subsidiaries (the “Company”) have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, all normal, recurring adjustments considered necessary for a fair presentation have been included. The consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes for the year ended December 31, 2011 included in the Annual Report on Form 10-K of the Company filed with the Securities and Exchange Commission on February 28, 2012. Interim results of operations are not necessarily indicative of the results to be expected for the full year or any other interim periods. There were no changes to the Company's significant accounting policies during the three month period ended March 31, 2012 other than detailed in the Recently Adopted Accounting Pronouncements below.

Use of Estimates, Policy [Policy Text Block]

Use of Estimates

The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates. There were no significant changes in estimates and assumptions used by management related to our critical accounting policies during the three months ended March 31, 2012.

Segment Reporting, Policy [Policy Text Block]

Segment Information

The Company has eleven regional operating divisions, in addition to operations at the Company's corporate headquarters; however, it has determined that it has one reportable segment. The operating divisions are operated out of our ten office locations including our corporate headquarters. All of the divisions are managed based on similar economic characteristics. Each of the regional operating divisions provides short-to-medium haul truckload carrier services of general commodities to a similar class of customers. In addition, each division exhibits similar financial performance, including average revenue per mile and operating ratio. As a result of the foregoing, the Company has determined that it is appropriate to aggregate its operating divisions into one reportable segment, consistent with the authoritative accounting guidance on disclosures about segments of an enterprise and related information. Accordingly, the Company has not presented separate segment financial information.

Marketable Securities, Held-to-maturity Securities, Policy [Policy Text Block]

Municipal bonds are classified as held to maturity, are carried at amortized cost and are included in other assets per the consolidated balance sheet and were $1.3 million at March 31, 2012 and December 31, 2011. Differences between amortized cost and fair value of municipal bonds are not considered material.

Marketable Securities, Available-for-sale Securities, Policy [Policy Text Block]

The guidance under U.S. GAAP defines fair value, specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable, and requires disclosures about fair value measurements.  The Company estimates the fair value of the auction rate securities applying the authoritative guidance on fair value measurements which establishes fair value as an estimate of what the Company could sell the investments for in an orderly transaction with a third party as of each measurement date. Observable inputs are inputs that reflect market data obtained from sources independent of the Company and unobservable inputs are inputs based on the Company’s own assumptions derived from the best information available in the circumstances.  These inputs are used in applying the following fair value hierarchy:

• Level 1 – quoted prices in active markets for identical assets or liabilities.

• Level 2 – quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; modeling with inputs that have observable inputs (i.e. interest rates observable at commonly quoted intervals.

• Level 3 – valuation is generated from model-based techniques that use significant assumptions not observable in the market.

Under the guidance, where applicable GAAP literature requires the use of fair value, the Company must value assets and liabilities at the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.  Additional authoritative literature provides guidance regarding the considerations necessary when markets are inactive.  The guidance indicates that quotes from brokers or pricing services may be relevant inputs when measuring fair value, but are not necessarily determinative in the absence of an active market for the asset.

Property, Plant and Equipment, Policy [Policy Text Block]

Property, Equipment, and Depreciation

Property and equipment are reported at cost, net of accumulated depreciation, while maintenance and repairs are charged to operations as incurred.   Tires are capitalized separately from revenue equipment and are reported separately as “Prepaid Tires” in the consolidated balance sheet and amortized over two years.  Depreciation expense of $0.2 million for the three months ended March 31, 2012 and 2011 has been included in communication and utilities in the consolidated statements of income. Depreciation for financial statement purposes is computed by the straight-line method for all assets other than tractors.  The Company recognizes depreciation expense on tractors acquired subsequent to January 1, 2009, at 150% declining balance. At March 31, 2012 and March 31, 2011100% and 72.7%, respectively of the Company's tractor fleet was depreciated based on the 150% declining balance method. Tractors are depreciated to salvage values of $15,000 while trailers are depreciated to salvage values of $4,000.

Earnings Per Share, Policy [Policy Text Block]

Earnings per Share

Basic earnings per share is based upon the weighted average common shares outstanding during each year.  Diluted earnings per share is based on the basic weighted earnings per share with additional weighted common shares for common stock equivalents. During the three months ended March 31, 2011 the Company did not have any common stock equivalents; therefore, diluted earnings per share were equal to basic earnings per share for those periods. During the three months ended March 31, 2012 the Company had grants of shares of common stock to certain employees of the Company under the 2011 Restricted Stock Award Plan. A reconciliation of the numerator (net income) and denominator (weighted average number of shares outstanding of the basic and diluted earnings per share ("EPS")) for the three months ended March 31, 2012 is as follows (in thousands, except per share data):

	2012
	Net Income (numerator) (in thousands)		Shares (denominator) (in thousands)	Per Share Amount
Basic EPS	$	16,588	86,475	$	0.19
Effect of restricted stock	—		351
Diluted EPS	$	16,588	86,826	$	0.19

Income Tax, Policy [Policy Text Block]

Income Taxes

Deferred income taxes are determined based upon the differences between the financial reporting and tax basis of the Company’s assets and liabilities.  Deferred taxes are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.

Income Tax Uncertainties, Policy [Policy Text Block]

The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained.  Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs.  The Company records interest and penalties related to unrecognized tax benefits in income tax expense.
