Accounting Policies [Abstract]
Basis of Presentation	(1) Basis of Presentation The accompanying unaudited consolidated financial statements of Universal Logistics Holdings, Inc. and its wholly-owned subsidiaries (collectively, “Universal” or the “Company”) have been prepared by the Company’s management. In the opinion of management, the unaudited consolidated financial statements include all normal recurring adjustments necessary to present fairly the information required to be set forth therein. All intercompany transactions and balances have been eliminated in consolidation. Certain information and note disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles have been condensed or omitted from these statements pursuant to such rules and regulations and, accordingly, should be read in conjunction with the consolidated financial statements as of December 31, 2017 and 2016 and for each of the years in the three-year period ended December 31, 2017 included in the Company’s Form 10-K filed with the Securities and Exchange Commission. The preparation of the consolidated financial statements requires the use of management’s estimates. Actual results could differ from those estimates. Our fiscal year ends on December 31 and consists of four quarters, each with thirteen weeks. The Company made certain immaterial reclassifications to items in its prior financial statements so that their presentation is consistent with the format in the financial statements for the period ended March 31, 2018. These reclassifications, however, had no effect on reported consolidated net income, comprehensive income, earnings per common share, cash flows, total assets or shareholders’ equity as previously reported.

Accounting Policies [Abstract]
Recent Accounting Pronouncements	(2) Recent Accounting Pronouncements Recently adopted accounting pronouncements On January 1, 2018, the Company adopted Accounting Standards Update (“ Revenue from Contracts with Customers with a cumulative adjustment to retained earnings of approximately $0.2 million or our transportation services businesses, which include truckload, brokerage, intermodal and dedicated services, the adoption of the standard changed the timing of revenue recognition from “at delivery” to “over-time” as the performance obligations on the in-transit services are completed. For our value-added service businesses, the adoption of the standard did not change the timing of revenue recognition. Due to the Company’s short in-transit period for transportation services, the impact did not have a material impact on its consolidated results of operations, financial position or cash flows. The adoption of ASU 2014-09 required an increase in the level of information disclosed in the Notes to Unaudited Consolidated Financial Statements. See Note 3 for additional information. On January 1, 2018, t he Company adopted ASU 2016-01, Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities , using the modified retrospective method. Upon adoption, approximately $3.8 million in accumulated changes in the fair market value of the Company’s equity securities that were presented at December 31, 2017 in accumulated other comprehensive income were reclassified to retained earnings . On January 1, 2018, the Company prospectively adopted ASU 2017-01, Business Combinations: Clarifying the Definition of a Business did not have an impact on its results of operations, financial position or cash flows.

Revenue Recognition

Revenue Recognition [Abstract]
Revenue Recognition	(3) Revenue Recognition The Company broadly groups its services into the following categories: truckload services, brokerage services, intermodal services, dedicated services and value-added services. Truckload services include dry van, flatbed, heavy-haul and refrigerated operations. We transport a wide variety of general commodities, including automotive parts, machinery, building materials, paper, food, consumer goods, furniture, steel and other metals on behalf of customers in various industries. To complement our available capacity, we provide customers freight brokerage services by utilizing third-party transportation providers to move freight. Brokerage services also include full service domestic and international freight forwarding, and customs brokerage. Intermodal services include rail-truck, steamship-truck and support services. Our intermodal support services are primarily short-to-medium distance delivery of rail and steamship containers between the railhead or port and the customer and drayage services. Dedicated services are primarily provided in support of automotive and retail customers using specialized van equipment. Dedicated services also include our final mile and ground expedited services. Our dedicated services are primarily short run or round-trip moves within a defined geographic area. (3) Revenue Recognition - continued Value-added services, which are typically dedicated to individual customer requirements, include material handling, consolidation, sequencing, sub-assembly, cross-dock services, kitting, repacking, warehousing and returnable container management. Value-added revenues are substantially driven by the level of demand for outsourced logistics services. Major factors that affect value-added service revenue includes changes in manufacturing supply chain requirements and production levels in specific industries, particularly the North American automotive and Class-8 heavy-truck industries. Revenue is recognized as control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration the Company expects to receive in exchange for its services. Our t ransportation services businesses include he adoption of ASU 2014-09 changed the timing of revenue recognition for transportation services from at delivery to over-time as the performance obligations on the in-transit services are completed. Transportation services are short-term in nature; agreements governing their provision generally have a term of less than one year. They do not contain significant financing components. In accordance with ASU 2014-09, the Company recognizes revenue over the period transportation services are provided to the customer, including service performed as of the end of the reporting period for loads currently in transit, in order to recognize the value that is transferred to a customer over the course of the transportation service. We determine revenue in-transit using the input method, under which revenue is recognized based on the duration of time that has lapsed from the departure date (start of transportation services) to the arrival date (completion of transportation services). Measurement of revenue in transit requires the application of significant judgment. We calculate the estimated percentage of an order’s transit time that is complete at period end, and we apply that percentage of completion to the order’s estimated revenue. For the Company’s value-added service businesses, the adoption of ASU 2014-09 did not change the timing of revenue recognition. The contracts in our value-added services businesses are negotiated agreements, which contain both fixed and variable components. The variability of revenues is driven by volumes and transactions, which are known as of an invoice date. Value-added service contracts typically have terms that extend beyond one year, and they do not include financing components. The timing of revenue recognition for value-added services will remain the same, as we have elected to use the “right to invoice” practical expedient, The following table provides information related to contract balances associated with our contracts with customers (in thousands): March 31, 2018 January 1, 2018 Prepaid expenses and other - contract assets $ 2,098 $ 1,361 We generally receive payment for performance obligations within 45 days of completion of transportation services and 65 days for completion of value-added services. Contract assets in the table above generally relate to revenue in transit at the end of the reporting period. Practical expedients The Company elected to use the following practical expedients that are available under ASC 606: (i) to apply the new revenue standard to a portfolio of contracts (or performance obligations) with similar characteristics, as we reasonably expect that the effects on the financial statements of applying this guidance to the portfolio would not differ materially from applying this guidance to the individual contracts; (ii) to recognize commission expense when incurred, which we consider to be a cost to obtain a contract, because the amortization period is less than one year; and (iii) to recognize revenue in the value-added services portfolio in the amount of consideration to which we have a right to invoice, that corresponds directly with the value to the customer of the service completed to date. The Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed. (3) Revenue Recognition - continued In accordance with the new revenue standard requirements, the impact of adoption on our consolidated statement of income and balance sheet was as follows (in thousands): Thirteen Weeks Ended March 31, 2018 Financial Statement Line Item Under ASC 605 Adjustment As Reported Consolidated Statement of Income Truckload services $ 75,780 $ 1,412 $ 77,192 Brokerage services 77,749 410 78,159 Intermodal services 46,428 181 46,609 Dedicated services 27,980 95 28,075 Purchased transportation and equipment rent 160,240 1,771 162,011 Commission expense 8,876 37 8,913 Income tax expense 3,645 77 3,722 Net income 10,221 213 10,434 Consolidated Balance Sheet Prepaid income taxes 870 (77 ) 793 Prepaid expenses and other 16,025 2,098 18,123 Accounts payable 102,048 1,808 103,856 Retained earnings 198,510 213 198,723 See also Note 13 for information on revenue reported by segment.

The fair value of marketable equity securities is determined based on quoted market prices in active markets, as described in Note 8. The following table sets forth market value, cost, and unrealized gains on equity securities (in thousands): March 31, 2018 December 31, 2017 Fair value $ 11,932 $ 15,144 Cost 8,784 10,231 Unrealized gain $ 3,148 $ 4,913 Prior to the Company’s adoption of ASU 2016-01 as of January 1, 2018 , unrealized losses in fair market value were presented as a component of Accumulated Other Comprehensive Income in shareholders’ equity; before adoption of this guidance, the Company included in net income only realized gains and losses and declines in value determined to be other-than-temporary on available-for-sale securities. The cost of securities determined to be in an other-than-temporary loss position was required to be presented net of the amount of the other-than-temporary impairment calculated. Subsequent to adoption of ASU 2016-01, cost is no longer presented net of other-than-temporary impairment. The December 31, 2017 cost reflected in the table above was presented net of approximately $424,000 of other-than-temporary impairment.

At March 31, 2018, the maximum available borrowing under the line of credit was $0.7 million. ( 7 ) Debt - continued The Company is also party to two interest rate swap agreements that qualify for hedge accounting. The swap agreements were executed to fix a portion of the interest rates on its variable rate debt that have a combined notional amount of $15.7 million at March 31, 2018. Under the swap agreements, the Company receives interest at the one-month LIBOR rate plus 2.25%, and pays a fixed rate. The March 2016 swap (swap A) became effective October 2016, has a rate of 4.16% (amortizing notional amount of $10.0 million) and expires July 2026, and an additional March 2016 swap (swap B) became effective October 2016, has a rate of 3.83% (amortizing notional amount of $5.7 million) and expires May 2022. At March 31, 2018, the fair value of the swap agreements was an asset of $0.5 million. Since these swap agreements qualify for hedge accounting, the changes in fair value are recorded in other comprehensive income (loss), net of tax. See Note 8 for additional information pertaining to interest rate swaps.

Fair Value Disclosures [Abstract]
Fair Value Measurements and Disclosures	( 8 ) Fair Value Measurements and Disclosures FASB ASC Topic 820, “ Fair Value Measurements and Disclosures, FASB ASC Topic 820 also establishes a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. This hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows: • Level 1 — Quoted prices in active markets for identical assets or liabilities. • Level 2 — Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. • Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs. ( 8 ) Fair Value Measurements and Disclosures – continued We have segregated all financial assets and liabilities that are measured at fair value on a recurring basis into the most appropriate level within the fair value hierarchy based on the inputs used to determine the fair value at the measurement date in the tables below (in thousands): March 31, 2018 Level 1 Level 2 Level 3 Fair Value Measurement Assets Marketable securities $ 11,932 $ — $ — $ 11,932 Interest rate swaps — 522 — 522 Total $ 11,932 $ 522 $ — $ 12,454 December 31, 2017 Level 1 Level 2 Level 3 Fair Value Measurement Assets Cash equivalents $ 75 $ — $ — $ 75 Marketable securities 15,144 — — 15,144 Interest rate swaps — 260 — 260 Total $ 15,219 $ 260 $ — $ 15,479 The valuation techniques used to measure fair value for the items in the tables above are as follows: • Cash equivalents – This category consists of money market funds which are listed as Level 1 assets and measured at fair value based on quoted prices for identical instruments in active markets. • Marketable securities – Marketable securities represent equity securities, which consist of common and preferred stocks, and are listed as Level 1 assets. Fair value was measured based on quoted prices for these securities in active markets. • Interest rate swaps – Our revolving credit and term loan agreements and our real estate promissory notes consist of variable rate borrowings. We categorize borrowings under these credit agreements as Level 2 in the fair value hierarchy. The carrying value of these borrowings approximate fair value because the applicable interest rates are adjusted frequently based on short-term market rates. For our equipment promissory notes, the fair values are estimated using discounted cash flow analyses, based on our current incremental borrowing rates for similar types of borrowing arrangements. We categorize borrowings under this credit agreement as Level 2 in the fair value hierarchy. The carrying value and estimated fair value of these promissory notes at March 31, 2018 is summarized as follows: Carrying Value Estimated Fair Value Equipment promissory notes $ 109,176 $ 107,566 We have not elected the fair value option for any of our financial instruments.

In connection with our transportation services, we also pay tolls and other fees for international bridge crossings to certain related entities which are under common control with CenTra. A significant number of our operating locations are located in facilities leased from affiliates. At 36 facilities, occupancy is based on either month-to-month or contractual, multi-year lease arrangements which are billed and paid monthly. Leasing properties provided by an affiliate that owns a substantial commercial property portfolio affords us significant operating flexibility; however, we are not limited to such arrangements. We purchase workers’ compensation, property and casualty, cargo, warehousing and other general liability insurance from an insurance company controlled by our majority shareholders. Our employee health care benefits and 401(k) programs are also provided by this affiliate. Other services from affiliates, including contracted transportation services, are delivered to us on a per-transaction-basis or pursuant to separate contractual arrangements provided in the ordinary course of business. At March 31, 2018 and December 31, 2017, amounts due to affiliates were $6.5 million and $12.0 million, respectively.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Stock Based Compensation	( 10 ) Stock Based Compensation On April 23, 2014, our Board of Directors adopted the 2014 Amended and Restated Stock Incentive Plan, or the Plan. The Plan was approved by our shareholders at the 2014 Annual Meeting and became effective as of the date it was adopted by the Board of Directors. The Plan replaced our 2004 Stock Incentive Plan and carried forward the shares of common stock that remained available for issuance under the 2004 Stock Incentive Plan. The grants may be made in the form of stock options, restricted stock bonuses, restricted stock purchase rights, stock appreciation rights, phantom stock units, restricted stock units or unrestricted common stock. Restricted stock awards currently outstanding under the 2004 Stock Incentive Plan will remain outstanding in accordance with the terms of that plan. On February 22, 2017, February 24, 2016, April 29, 2015 and March 5, 2015, the Company granted 10,000, 10,000, 20,000 and 10,000 shares, respectively, of restricted stock to our Chief Executive Officer. The restricted stock grants have fair values of $13.45 per share, $15.55 per share, $22.03 per share, and $25.18 per share, respectively, based on the closing price of the Company’s stock on each grant date. For each award, 25% of the shares vested immediately on the grant dates, and the remaining shares vest in three equal installments with the final vesting of the 2017 award to occur on March 5, 2020, in each case subject to continued employment with the company. On December 23, 2015, the Company granted 50,000 shares of restricted stock to certain of its employees, including 10,000 shares to our Chief Financial Officer. The restricted stock grants have a grant date fair value of $14.93 per share, based on the closing price of the Company’s stock, of which 25% vested immediately, and an additional 25% will vest in three equal increments on each December 20 in 2016, 2017 and 2018. A grantee’s vesting of restricted stock awards may be accelerated under certain conditions, including retirement. The following table summarizes the status of the Company’s non-vested shares and related information for the period indicated: Shares Weighted Average Date Non-vested at January 1, 2018 31,250 $ 16.63 Granted — $ — Vested (12,500 ) $ 19.65 Forfeited — $ — Balance at March 31, 2018 18,750 $ 14.62 In each of the thirteen-week periods ended March 31, 2018 and April 1, 2017, the total grant date fair value of vested shares recognized as compensation costs was $0.2 million. As of March 31, 2018, there was approximately $0.3 million of total unrecognized compensation cost related to non-vested share-based compensation arrangements. That cost is expected to be recognized on a straight-line basis over the remaining vesting period. As a result, the Company expects to recognize stock-based compensation expense of $0.1 million during the remainder of 2018, and $0.1 million in each of 2019 and 2020.

Earnings Per Share [Abstract]
Earnings Per Share	( 1 1 ) Earnings Per Share Basic earnings per common share amounts are based on the weighted average number of common shares outstanding, excluding outstanding non-vested restricted stock. Diluted earnings per common share include dilutive common stock equivalents determined by the treasury stock method. For the thirteen weeks ended March 31, 2018 and April 1, 2017, there were 6,750 and 346 weighted average non-vested shares of restricted stock, respectively, included in the denominator for the calculation of diluted earnings per share. For the thirteen weeks ended April 1, 2017, 35,000 shares of non-vested restricted stock were excluded from the calculation of diluted earnings per share because such shares were anti-dilutive. No shares were excluded from the calculation of diluted earnings per share for the thirteen weeks ended March 31, 2018.

Dividends	(1 2 ) Dividends On February 21, 2018, our Board of Directors approved an increase in the Company’s annual cash dividend policy from $0.28 per share to $0.42 per share beginning in 2018. The first quarterly installment of $0.105 per share is expected to be declared after the conclusion of the first quarter of 2018. After taking into account the regular quarterly dividends made during the year, the Board of Directors also intends to evaluate the potential declaration of an annual special dividend payable in the first quarter of each year in an effort to return up to 40% of Universal’s net income from the previous fiscal year, beginning in the first quarter of 2019. Pursuant to the cash dividend policy in effect until February 21, 2018, the Board of Directors declared a quarterly cash dividend of $0.07 per share of common stock, payable to shareholders of record at the close of business on March 5, 2018 and paid on March 15, 2018. Declaration of future cash dividends is subject to final determination by the Board of Directors each quarter after its review of our financial condition, results of operations, capital requirements, any legal or contractual restrictions on the payment of dividends and other factors the Board of Directors deems relevant.

Segment Reporting [Abstract]
Segment Reporting	(1 3 ) Segment Reporting We report our financial results in two reportable segments, the transportation segment and the logistics segment, based on the nature of the underlying customer commitment and the types of investments required to support these commitments. This presentation reflects the manner in which management evaluates our operating segments, including an evaluation of economic characteristics and applicable aggregation criteria. Operations aggregated in our transportation segment are associated with individual freight shipments coordinated by our agents, company-managed terminals and specialized services operations. In contrast, operations aggregated in our logistics segment deliver value-added services or transportation services to specific customers on a dedicated basis, generally pursuant to contract terms of one year or longer. Other non-reportable operating segments are comprised of the Company’s subsidiaries that provide support services to other subsidiaries and to owner-operators, including shop maintenance and equipment leasing. The following tables summarize information about our reportable segments as of and for the thirteen week period ended March 31, 2018 and April 1, 2017 (in thousands): Thirteen weeks ended March 31, 2018 Transportation Logistics Other Total Operating revenues $ 206,108 $ 128,648 $ 357 $ 335,113 Eliminated inter-segment revenues 771 2,803 - 3,574 Income from operations 10,113 7,433 (442 ) 17,104 Total assets 335,673 306,113 20,682 662,468 Thirteen weeks ended April 1, 2017 Transportation Logistics Other Total Operating revenues $ 178,397 $ 105,735 $ 310 $ 284,442 Eliminated inter-segment revenues 285 1,908 - 2,193 Income from operations 6,353 4,193 (1,377 ) 9,169 Total assets 261,974 299,504 21,595 583,073

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	(1 4 ) Commitments and Contingencies Our principal commitments relate to long-term real estate leases and payment obligations to equipment vendors. On October 16, 2017, a jury in state court in Cook County, Illinois rendered a verdict of $54.2 million against Universal Am-Can, Ltd. (“UACL”) in the matter of Denton v. UACL, et al. The litigation relates to a vehicular accident that occurred on February 8, 2011 on I-65 in Rensselaer, Indiana. The accident involved a tractor-trailer being driven by an independent owner-operator of UACL. The driver was braking on the expressway in order to avoid another vehicle being driven the wrong way on the interstate. The truck attempted to avoid the oncoming vehicle and the plaintiff’s vehicle and, in so doing, struck the plaintiff’s vehicle. As a result of the accident, the plaintiff sustained non-life threatening injuries. In connection with the verdict, the jury determined that UACL was responsible for the liability associated with the accident. The verdict included $19.2 million in compensatory damages and $35.0 million in punitive damages against UACL. The insurance coverage available for reimbursement of UACL’s damages underlying the verdict is limited to $1.0 million. We believe the facts and the law do not support the jury’s findings of liability against UACL. Post-trial motions have been filed seeking a reduction of the verdict or reversal of the judgment. The Company may further seek to appeal the verdict to the extent the circuit court does not set it aside the judgment as a result of these motions. The Company currently estimates the possible range of financial exposure in the matter, net of insurance coverage, to be between $18.2 and $53.2 million. Based on the Company’s best estimate of the liability at this time, the Company has recorded an accrued liability for this matter of $18.2 million. While we cannot predict with any certainty the outcome of this litigation, its ultimate resolution could be significantly different from our estimate and materially affect our financial condition, results of operations and cash flows. The Company was plaintiff in a lawsuit that was filed on June 11, 2015 against, among others, Dalton Logistics, Inc. (“Dalton”) in the United States District Court for the Southern District of Texas. The Company was seeking approximately $1.9 million in damages from a debtor relating to unpaid freight charges. In response to the filing of the complaint, the shareholders of Dalton filed a counterclaim against the Company alleging that the Company, in connection with certain unrelated negotiations with the defendant, breached an alleged agreement to acquire Dalton. The respective claims proceeded to trial and, on July 21, 2017, a jury returned two separate verdicts: One in favor of Universal for $1.9 million, and a second in favor of the defendant for approximately $5.7 million. On October 30, 2017, the court entered a judgment against Universal for the $5.7 million, but ignored the $1.9 million jury award in favor of Universal. The Company believes this ruling was in error and further believes the jury erred in their findings of any damages against Universal, and therefore, the Company plans to appeal both the ruling and the verdict. The Company currently estimates the possible range of financial exposure in the matter to be between $0 and $5.7 million. Based on the Company’s best estimate of the liability at this time, the Company has recorded an accrued liability for this matter of $1.8 million. While we cannot predict with any certainty the outcome of this litigation, management does not believe the outcome will have a material adverse effect on our business, financial condition, results of operations or cash flows. On February 21, 2018, Ford Motor Company (“Ford”) filed suit against two of the Company’s subsidiaries and two related parties in state court in Oakland County, Michigan (the “Indemnity Action”). The complaint seeks a declaratory judgment that Universal and its co-defendants are required to indemnify Ford for damages sustained by Ford in a wrongful death lawsuit in Clay County, Missouri (the “Underlying Action”). In February 2018, a jury returned a verdict against Ford in the Underlying Action and awarded the decedent’s estate $76 million in damages. Universal believes that, under Michigan law and its agreement with Ford, Universal is not required to indemnify Ford for Ford’s own negligence that led to the jury verdict in the Underlying Action. Additionally, at the time of the incident that is the subject of the Underlying Action, Universal had in place insurance required by Ford providing for up to $3.0 million of coverage from a co-defendant. The Company currently estimates the possible range of financial exposure in the matter, net of insurance coverage, to be between $0 and $73 million. Based on our knowledge of the facts associated with the Underlying Action and the Indemnity Action and the opinions of outside counsel, Universal has determined that no accrual is necessary at this time. While the outcome of the Indemnity Action cannot be predicted with any certainty and management believes the Company will be successful in defending its position, the outcome could have material adverse effect on our business, financial position, results of operations and cash flows. (14 ) Commitments and Contingencies - continued The Company is involved in certain other claims and pending litigation arising from the ordinary conduct of business. We also provide accruals for claims within our self-insured retention amounts. Based on the knowledge of the facts, and in certain cases, opinions of outside counsel, in the Company’s opinion the resolution of these claims and pending litigation will not have a material effect on our financial position, results of operations or cash flows. However, if we experience claims that are not covered by our insurance or that exceed our estimated claim reserve, it could increase the volatility of our earnings and have a materially adverse effect on our financial condition, results of operations or cash flows. At March 31, 2018, approximately 26% of our employees in the United States, Canada and Colombia, and 94% of our employees in Mexico are subject to collective bargaining agreements that are renegotiated periodically, none of which are subject to contracts that expire in 2018.

For our value-added service businesses, the adoption of the standard did not change the timing of revenue recognition. Due to the Company’s short in-transit period for transportation services, the impact did not have a material impact on its consolidated results of operations, financial position or cash flows. The adoption of ASU 2014-09 required an increase in the level of information disclosed in the Notes to Unaudited Consolidated Financial Statements. See Note 3 for additional information. On January 1, 2018, t he Company adopted ASU 2016-01, Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities , using the modified retrospective method.
