Organization and Operations U.S. Xpress Enterprises, Inc. and its consolidated subsidiaries (collectively, the “Company”, “we”, “us”, “our”, and similar expressions) provide transportation services throughout the United States, with a focus in the densely populated and economically diverse eastern half of the United States.

Our Brokerage segment is principally engaged in non-asset-based freight brokerage services, where loads are contracted to third-party carriers. Under our Articles of Incorporation, our authorized capital stock consists of 140,000,000 shares of Class A common stock, par value $0.01 per share, 35,000,000 shares of Class B common stock, par value $0.01 per share, and 9,333,333 shares of preferred stock, the rights and preferences of which may be designated by the Board of Directors. ​

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Presentation The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned and majority owned subsidiaries. All significant intercompany transactions and accounts have been eliminated. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with Article 10 of Regulation S-X promulgated under the Securities Act of 1933, as amended. The preparation of financial statements in conformity with 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, and such differences could be material. In the opinion of management, the accompanying financial statements include all adjustments that are necessary for a fair statement of the results of the interim periods presented, such adjustments being of a normal recurring nature. Certain information and footnote disclosures have been condensed or omitted pursuant to such rules and regulations. The December 31, 2019 balance sheet was derived from our audited balance sheet as of that date. The Company’s operating results are subject to seasonal trends when measured on a quarterly basis; therefore operating results for the three and six months ended June 30, 2020 are not necessarily indicative of the results that may be expected for the year ending December 31, 2020. These unaudited condensed consolidated financial statements and notes thereto should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2019. Recently Issued Accounting Standards On December 18, 2019, the FASB issued Accounting Standards Update (“ASU”) 2019-12, which modifies Accounting Standards Codification (“ASC”) 740 to simplify the accounting for income taxes. The amendments in ASU 2019-12 are effective for public business entities for fiscal years beginning after December 15, 2020, including interim periods therein. Early adoption of the standard is permitted, including adoption in interim or annual periods for which financial statements have not yet been issued. The Company has not early adopted this guidance and will continue to evaluate the impact on its financial statements. Recently Adopted Accounting Standards In June 2016, the FASB issued ASU No. 2016-13 Financial Instruments-Credit Losses (Topic 326) amending how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The guidance requires the application of a current expected credit loss model, which is a new impairment model based on expected losses. We adopted ASU 2016-13 effective January 1, 2020 and the application of this guidance did not have a material impact on our financial statements. ​ In January 2017, the FASB issued ASU 2017-04, “Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment,” which eliminates Step 2 from the goodwill impairment testing process. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount. Under the new standard, a goodwill impairment loss is measured as the excess of the carrying value of a reporting unit over its fair value. We adopted ASU 2017-04 effective January 1, 2020 and the application of this guidance did not have a material impact on our financial statements. ​ ​

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	6. Commitments and Contingencies The Company is party to certain legal proceedings incidental to its business. The ultimate disposition of these matters, in the opinion of management, based in part on the advice of legal counsel, is not expected to have a materially adverse effect on the Company’s financial position or results of operations. For the cases described below, management is unable to provide a meaningful estimate of the possible loss or range of loss because, among other reasons, (1) the proceedings are in various stages; (2) damages have not been sought; (3) damages are unsupported and/or exaggerated; (4) there is uncertainty as to the outcome of the proceedings, including pending appeals; and/or (5) there are significant factual issues to be resolved. For these cases, however, management does not believe, based on currently available information, that the outcomes of these proceedings will have a material adverse effect on our financial condition, though the outcomes could be material to our operating results for any particular period, depending, in part, upon the operating results for such period. California Wage and Hour Class Action Litigation On December 23, 2015, a class action lawsuit was filed against the Company and its subsidiary U.S. Xpress, Inc. in the Superior Court of California, County of San Bernardino. The Company removed the case from state court to the U.S. District Court for the Central District of California. The plaintiff’s initial proposed class certification (any employee driver who has driven in California at any time since December 23, 2011) was denied by the district court under Rule 26 due to lack of commonality amongst the putative class members. The Court granted the plaintiff’s revised Motion for Class Certification, and the certified class now consists of all employee drivers who resided in California and who have driven in the State of California on behalf of U.S. Xpress at any time since December 23, 2011. The case alleges that class members were not paid for off-the-clock work, were not provided duty free meal or rest breaks, and were not paid premium pay in their absence, were not paid the California minimum wage for all hours worked in that state, were not provided accurate and complete itemized wage statements and were not paid all accrued wages at the end of their employment, all in violation of California law. The class seeks a judgment for compensatory damages and penalties, injunctive relief, attorney fees, costs and pre- and post-judgment interest. On May 2, 2019, the district court dismissed on grounds of preemption the claims alleging failure to provide duty free meal and rest breaks or to pay premium pay for failure to provide such breaks under California law. The parties also filed cross-motions for summary judgment on the remaining claims, and the Company filed a motion to decertify the class. The court recently issued it ruling on the pending cross-motions: (1) the court denied the Company’s motion to decertify the class; (2) the court granted the Company’s motion for summary judgment on the plaintiff’s minimum wage claim for non-driving duties such as pre-trip and post-trip inspection, fueling, receiving dispatches, waiting to load or unload, and handling paperwork for the loads for January 1, 2013 forward (leaving the minimum wage claim only for the approximate one The plaintiff has filed a petition for permission to file an interlocutory appeal of the court’s decision on the minimum wage claim, which the court has granted and is presently before the Ninth Circuit Court of Appeals for final determination as to whether the plaintiff will be given permission to file the appeal. The parties will complete expert discovery over the next several months, and a jury trial is set to begin on February 16, 2021. We are currently not able to predict the probable outcome or to reasonably estimate a range of potential losses, if any. We intend to vigorously defend the merits of these claims. Stockholder Claims As set forth below, between November 2018 and April 2019, eight substantially similar putative securities class action complaints were filed against the Company and certain other defendants: five in the Circuit Court of Hamilton County, Tennessee (“Tennessee State Court Cases”), two in the U.S. District Court for the Eastern District of Tennessee (“Federal Court Cases”), and one in the Supreme Court of the State of New York (“New York State Court Case”). Two of the Tennessee State Court Cases and one of the Federal Court Cases have been voluntarily dismissed. All of these matters are in preliminary stages of litigation, and discovery has not yet begun. We are currently not able to predict the probable outcome or to reasonably estimate a range of potential losses, if any. On November 21, 2018, a putative class action complaint was filed in the Circuit Court of Hamilton County, Tennessee against the Company, five of our officers or directors, and the seven underwriters who participated in our June 2018 initial public offering (“IPO”), alleging violations of Sections 11 and 15 of the Securities Act of 1933 (the “Securities Act”). The class action lawsuit is based on allegations that the Company made false and/or misleading statements in the registration statement and prospectus filed with the Securities and Exchange Commission (“SEC”) in connection with the IPO. The lawsuit is purportedly brought on behalf of a putative class of all persons or entities who purchased or otherwise acquired the Company’s Class A common stock pursuant and/or traceable to the IPO, and seeks, among other things, compensatory damages, costs and expenses (including attorneys’ fees) on behalf of the putative class. On January 23, 2019, a substantially similar putative class action complaint was filed in the Circuit Court of Hamilton County, Tennessee, by a different plaintiff alleging claims under Sections 11 and 15 of the Securities Act against the same defendants as in the action commenced on November 21, 2018. On March 7, 2019, this case was voluntarily dismissed by the plaintiff. On January 30, 2019, a substantially similar putative class action complaint was filed in the Circuit Court of Hamilton County, Tennessee, by a different plaintiff alleging claims under Sections 11 and 15 of the Securities Act against the same defendants as in the action commenced on November 21, 2018, and also alleging a claim under Section 12 of the Securities Act. On February 5, 2019, a substantially similar putative class action complaint was filed in the Circuit Court of Hamilton County, Tennessee, by a different plaintiff alleging claims under Sections 11 and 15 of the Securities Act against the same defendants as in the action commenced on November 21, 2018, and also alleging a claim under Section 12 of the Securities Act. On February 6, 2019, a substantially similar putative class action complaint was filed in the Circuit Court of Hamilton County, Tennessee, by different plaintiffs alleging claims under Sections 11 and 15 of the Securities Act against the same defendants as in the action commenced on November 21, 2018. On March 19, 2019, this case was voluntarily dismissed by the plaintiff. On March 8, 2019, a substantially similar putative class action complaint was filed in the U.S. District Court for the Eastern District of Tennessee by a different plaintiff alleging claims under Sections 11 and 15 of the Securities Act against the same defendants as in the action commenced on November 21, 2018. On May 9, 2019, this case was voluntarily dismissed by the plaintiff. On March 14, 2019, a substantially similar putative class action complaint was filed in the Supreme Court of the State of New York, County of New York, by a different plaintiff alleging claims under Sections 11 and 15 of the Securities Act against the same defendants as in the action commenced on November 21, 2018. The parties have stipulated to extend the time for defendants to respond to the complaint in this matter pending resolution of the motions to dismiss filed (or to be filed) in the remaining of the Tennessee State Court Cases and the Federal Court Cases. On April 2, 2019, a substantially similar putative class action complaint was filed in the U.S. District Court for the Eastern District of Tennessee, by a different plaintiff alleging claims under Sections 11 and 15 of the Securities Act against the Company and the same five officers and directors as in the action commenced on November 21, 2018. Unlike the previously filed complaints, this complaint did not name as defendants any of the seven underwriters who participated in our IPO; however, an amended complaint was filed on October 8, 2019 (“Amended Federal Complaint”) which added all underwriters who participated in the IPO as defendants. The three remaining Tennessee State Court Cases have been consolidated, and discovery is currently stayed pending a decision on a motion to dismiss filed by the Company and the other defendants. On June 28, 2019, the defendants filed a Motion to Dismiss the Tennessee State Court Cases for failure to allege facts sufficient to support a violation of either Section 11, 12 or 15 of the Securities Act. On July 18, 2019, the court presiding over the remaining of the Federal Court Cases issued an order appointing lead plaintiff and lead counsel. Pursuant to a stipulation entered in that matter, the appointed lead plaintiff filed the Amended Federal Complaint on October 8, 2019. The Amended Federal Complaint is made on behalf of a putative class that consists of all persons who purchased or otherwise acquired the Class A common stock of the Company between June 14, 2018 and November 1, 2018 and who were allegedly damaged thereby. In addition, the Amended Federal Complaint alleges additional violations of Section 10(b) and 20(a) of the Securities Exchange Act of 1934 (“Exchange Act”) against the Company, its Chief Executive Office and its Chief Financial Officer. On December 23, 2019, the defendants filed a motion to dismiss the Amended Federal Complaint in its entirety for failure to allege facts sufficient to state a claim under either the Securities Act or the Exchange Act. Plaintiffs filed their Opposition to that Motion on March 9, 2020, and the Company filed its Reply brief on April 23, 2020. On June 30, 2020, the court presiding over the remaining Federal Court Cases issued its ruling granting in part and denying in part the defendants’ motions to dismiss the Amended Federal Complaint. The court dismissed entirely plaintiffs’ claims for alleged violations of the Exchange Act and further held that plaintiffs failed to state a claim for violation of the Securities Act with respect to the majority of statements challenged as false or misleading in the Federal Amended Complaint. The court, however, held that the Federal Amended Complaint sufficiently alleged violations of the Securities Act to survive a motion to dismiss with respect to two statements from the June 2018 IPO registration statement and prospectus that plaintiffs alleged to be false or misleading, both on theories of alleged misrepresentations and material omissions. Accordingly, the court allowed this action to proceed beyond the pleading stage, but only with respect to the statements deemed sufficient to support a Securities Act claim when assuming the truth of plaintiffs’ allegations. Defendants’ answers to the Federal Amended Complaint are to be filed by August 14, 2020, and the case will proceed to the discovery phase. The complaints in all the actions listed above allege that the Company made false and/or misleading statements in the registration statement and prospectus filed with the SEC in connection with the IPO, and that, as a result of such alleged statements, the plaintiffs and the members of the putative classes suffered damages. The Amended Federal Complaint additionally alleged that the Company, its Chief Executive Officer and its Chief Financial Officer made false and/or misleading statements and/or material omissions in press releases, earnings calls, investor conferences, television interviews, and filings made with the SEC subsequent to the IPO; however, claims with respect to those challenged statements were dismissed in the court’s June 30, 2020 ruling on defendants’ motions to dismiss. We believe the allegations made in the complaints are without merit and intend to defend ourselves vigorously in these matters. Stockholder Derivative Action On June 7, 2019, a stockholder derivative lawsuit was filed in the District Court for Clark County, Nevada against five of our executives and all five of our independent board members (collectively, the “Individual Defendants”), and naming the Company as a nominal defendant. The complaint alleges that the Company made false and/or misleading statements in the registration statement and prospectus filed with the SEC in connection with the IPO and that the Individual Defendants breached their fiduciary duties by causing or allowing the Company to make such statements. The complaint alleges that the Company has been damaged by the alleged wrongful conduct as a result of, among other things, being subjected to the time and expense of the securities class action lawsuits that have been filed relating to the IPO. In addition to a claim for alleged breach of fiduciary duties, the lawsuit alleges claims against the Individual Defendants for unjust enrichment, abuse of control, gross mismanagement, and waste of corporate assets. The parties have stipulated to a stay of this proceeding pending the filing of an answer or a dismissal in the remaining of the Tennessee State Court Cases or the Federal Court Cases. This matter is in the preliminary stages of litigation and discovery has not yet begun. We are currently not able to predict the probable outcome or to reasonably estimate a range of potential losses, if any. We believe the allegations made in the complaint are without merit and intend to defend ourselves vigorously in these matters. Independent Contractor Class Action On March 26, 2019, a putative class action complaint was filed in the U.S. District Court for the Eastern District of Tennessee against the Company and its subsidiaries U.S. Xpress, Inc. and U.S. Xpress Leasing, Inc. The putative class includes all individuals who performed work for U.S. Xpress, Inc. or U.S. Xpress Leasing, Inc. as lease drivers from March 26, 2016 to present. The complaint alleges that independent contractors are improperly designated as such and should be designated as employees and thus subject to the Fair Labor Standards Act (“FLSA”). The complaint further alleges that U.S. Xpress, Inc.’s pay practices for the putative class members violated the minimum wage provisions of the FLSA for the period from March 26, 2016 to present. The complaint further alleges that the Company violated the requirements of the Truth in Leasing Act with regard to the independent contractor agreements and lease purchase agreements it entered into with the putative class members. The complaint further alleges that the Company failed to comply with the terms of the independent contractor agreements and lease purchase agreements entered into with the putative class members, that it violated the provisions of the Tennessee Consumer Protection Act in advertising, describing and marketing the lease purchase program to the putative class members, and that it was unjustly enriched as a result of the foregoing allegations. We filed a Motion to Compel Arbitration on October 18, 2019. On January 17, 2020, the court granted that motion, in part, compelling arbitration on all of the plaintiff’s claims and denying the plaintiff’s motion for conditional certification of a collective action. The court further stayed the matter pending arbitration, rather than dismissing it entirely. On March 6, 2020, the plaintiff petitioned the court to certify the decision for an interlocutory appeal. The Company filed an opposition to plaintiff’s motion on March 20, 2020, and plaintiff filed her reply on April 3, 2020, purportedly relying, in part, on a recent case from Massachusetts. In response to that newly cited case, the Company was granted leave to file a surreply, which it filed on April 13, 2020. The district court has not yet ruled on the plaintiff’s petition for interlocutory appeal. There has been no discovery in this matter, and we are currently not able to predict the probable outcome or to reasonably estimate a range of potential losses, if any. We believe the allegations made in the complaint are without merit and intend to defend ourselves vigorously against the complaints relating to such actions. On June 25, 2020, a second putative collective and class action complaint was filed against the Company and its subsidiaries U.S. Xpress, Inc. and U.S. Xpress Leasing, Inc. in the U.S. District Court for the Eastern District of Tennessee. The putative class and collective action includes all current and former over-the-road truck drivers classified as independent contractors and employed by us during the applicable statute of limitations. The complaint alleges that independent contractors are improperly designated as such and should be designated as employees subject to the FLSA. The complaint alleges that U.S. Xpress, Inc.’s pay practices for the putative collective and class members violated the minimum wage provisions of the FLSA for the period from June 25, 2017 to the present. The complaint further alleges that we failed to pay the plaintiff and members of the class for all miles they drove and breached the contract between the parties and that we were unjustly enriched as a result of the foregoing allegations. The parties have met and conferred to discuss the plaintiff’s claims, and the plaintiff has agreed to file a joint stipulation that his claim would be submitted to individual arbitration and asking the court to stay the case pending arbitration. There has been no discovery in this matter, and we are currently not able to predict the probable outcome or to reasonably estimate a range of potential losses, if any. We believe the allegations made in the complaint are without merit and intend to defend ourselves vigorously against the complaints relating to such actions Phishing Attack Class Action On June 5, 2020, a putative class action lawsuit was filed against the Company in the U.S. District Court for the Eastern District of Tennessee arising out of a September 2019 phishing attack on the Company. Plaintiffs allege their personally identifiable information (“PII”) was compromised. Plaintiffs further allege that the Company failed to implement adequate security measures to prevent the phishing attack and failed to provide individuals whose PII was potentially impacted with timely and accurate notice. Plaintiffs bring the lawsuit on behalf of themselves and a putative class of “[a]ll persons residing in the United States whose PII was exposed” as a result of the phishing attack. Plaintiffs also assert a Florida-specific subclass. Plaintiffs assert claims for negligence, negligence per se, breach of confidence, and breach of implied contract. The Company’s deadline for responding to the complaint is August 3, 2020. We believe all of the counts in the complaint are without merit and intend to defend ourselves vigorously in this matter. Other The Company had letters of credit of $32.7 million outstanding as of June 30, 2020. The letters of credit are maintained primarily to support the Company’s insurance program. The Company had cancelable commitments outstanding at June 30, 2020 to acquire revenue equipment for approximately $87.4 million during the remainder of 2020. These purchase commitments are expected to be financed by operating leases, long-term debt and proceeds from sales of existing equipment. ​

The common stock will be purchased in January and July of each year. The Company recognized compensation expense of $0.0 million and $0.1 million for the three and six months ended June 30, 2020, and $0.1 million for the three and six months ended June 30, 2019, respectively, associated with the plan.

Segment Reporting [Abstract]
Segment Information	9. Segment Information The Company’s business is organized into two reportable segments, Truckload and Brokerage. The Truckload segment offers asset-based truckload services, including OTR trucking and dedicated contract services. These services are aggregated because they have similar economic characteristics and meet the aggregation criteria described in the accounting guidance for segment reporting. The Company’s OTR service offering provides solo and expedited team services through one-way movements of freight over routes throughout the United States. The Company’s dedicated contract service offering devotes the use of equipment to specific customers and provides services through long-term contracts. The Company’s dedicated contract service offering provides similar freight transportation services, but does so pursuant to agreements where it makes equipment, drivers and on-site personnel available to a specific customer to address needs for committed capacity and service levels. The Company’s Brokerage segment is principally engaged in non-asset-based freight brokerage services, where it outsources the transportation of loads to third-party carriers. For this segment, the Company relies on brokerage employees to procure third-party carriers, as well as information systems to match loads and carriers.

Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned and majority owned subsidiaries. All significant intercompany transactions and accounts have been eliminated. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with Article 10 of Regulation S-X promulgated under the Securities Act of 1933, as amended. The preparation of financial statements in conformity with 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, and such differences could be material. In the opinion of management, the accompanying financial statements include all adjustments that are necessary for a fair statement of the results of the interim periods presented, such adjustments being of a normal recurring nature. Certain information and footnote disclosures have been condensed or omitted pursuant to such rules and regulations. The December 31, 2019 balance sheet was derived from our audited balance sheet as of that date. The Company’s operating results are subject to seasonal trends when measured on a quarterly basis; therefore operating results for the three and six months ended June 30, 2020 are not necessarily indicative of the results that may be expected for the year ending December 31, 2020. These unaudited condensed consolidated financial statements and notes thereto should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2019.
Recently Issued and Recently Adopted Accounting Standards	Recently Issued Accounting Standards On December 18, 2019, the FASB issued Accounting Standards Update (“ASU”) 2019-12, which modifies Accounting Standards Codification (“ASC”) 740 to simplify the accounting for income taxes. The amendments in ASU 2019-12 are effective for public business entities for fiscal years beginning after December 15, 2020, including interim periods therein. Early adoption of the standard is permitted, including adoption in interim or annual periods for which financial statements have not yet been issued. The Company has not early adopted this guidance and will continue to evaluate the impact on its financial statements. Recently Adopted Accounting Standards In June 2016, the FASB issued ASU No. 2016-13 Financial Instruments-Credit Losses (Topic 326) amending how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The guidance requires the application of a current expected credit loss model, which is a new impairment model based on expected losses. We adopted ASU 2016-13 effective January 1, 2020 and the application of this guidance did not have a material impact on our financial statements. ​ In January 2017, the FASB issued ASU 2017-04, “Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment,” which eliminates Step 2 from the goodwill impairment testing process. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount. Under the new standard, a goodwill impairment loss is measured as the excess of the carrying value of a reporting unit over its fair value. We adopted ASU 2017-04 effective January 1, 2020 and the application of this guidance did not have a material impact on our financial statements.
