| Business Description | The consolidated financial statements include the accounts of Landstar System, Inc. and its subsidiary, Landstar System Holdings, Inc., and reflect all adjustments (all of a normal, recurring nature) which are, in the opinion of management, necessary for a fair statement of the results for the periods presented. The preparation of the consolidated financial statements requires the use of management’s estimates. Actual results could differ from those estimates. Landstar System, Inc. and its subsidiary are herein referred to as “Landstar” or the “Company.” Significant intercompany accounts have been eliminated in consolidation. Landstar owns, through various subsidiaries, a controlling interest in Landstar Metro, S.A.P.I. de C.V., a transportation logistics company (“Landstar Metro”), and Landstar Metro Servicios S.A.P.I. de C.V., a services company (“Landstar Servicios”), each based in Mexico City, Mexico. Given Landstar’s controlling interest in each of Landstar Metro and Landstar Servicios, the accounts of Landstar Metro and Landstar Servicios have been consolidated herein and a noncontrolling interest has been recorded for the noncontrolling investors’ interests in the net assets and operations of Landstar Metro and Landstar Servicios. In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2014-09—Revenue from Contracts with Customers (“ASU 2014-09”). The new comprehensive revenue recognition standard supersedes all existing revenue recognition guidance under U.S. GAAP. The Company adopted ASU 2014-09 on December 31, 2017 under the modified retrospective transition method resulting in a $773,000 cumulative adjustment to retained earnings. The Company has updated our revenue recognition policy included in our Annual Report on Form 10-K for the year ended December 30, 2017, as set forth below in footnote 1 to our unaudited financial statements. |

| Significant Accounting Policies |
Revenue Recognition The nature of the Company’s freight transportation services and its performance obligations to customers, regardless of the mode of transportation used to perform such services, relate to the safe and on-time pick-up and delivery of a customer’s freight on a shipment-by-shipment basis. Landstar customers are typically invoiced on a shipment-by-shipment basis at a pre-defined rate, payable thirty to sixty (30-60) days after the customer’s receipt of such invoice. Payment terms to customers do not contain a significant financing component and the amount owed by the customer does not contain variable terms, embedded or otherwise. We have determined that revenue recognition over the transit period provides a faithful depiction of the transfer of services to the customer as our obligation for which we are primarily responsible for fulfilling is performed over the transit period. Accordingly, transportation revenue billed to a customer for the physical transportation of freight and related direct freight expenses are recognized on a gross basis over the transit period as the performance obligation is satisfied. The Company determines the transit period for a given shipment based upon the pick-up date and the delivery date, which may be estimated if delivery has not occurred as of the reporting date. Determining the transit period and how much of it has been completed as of a given reporting date may therefore require management to make judgments that affect the timing of revenue recognized. With respect to shipments with a pick-up date in one reporting period and a delivery date in another, the Company recognizes such transportation revenue based on relative transit time in each reporting period. A days in transit output method is used to measure the progress of the performance of the Company’s freight transportation services as of the reporting date and a portion of the total revenue that will be billed to the customer once a load is delivered is recognized in each reporting period based on the percentage of total transit time that has been completed at the end of the applicable reporting period. |

| Acquired Business and Noncontrolling Interests |
During 2017, the Company incorporated each of Landstar Metro and Landstar Servicios. On September 20, 2017, Landstar Metro acquired substantially all of the assets of the asset-light transportation logistics business of Fletes Avella, S.A. de C.V., a Mexican transportation logistics company (the “Mexican Asset Acquisition”). At December 30, 2017, there was approximately $1,900,000 in liabilities outstanding consisting of additional contingent purchase price and associated indirect taxes. In connection with the Mexican Asset Acquisition, individuals affiliated with the seller subscribed in the aggregate for equity interests in Landstar Metro and Landstar Servicios and, as of September 29, 2018, own in the aggregate approximately 21% of the equity interests of each of them. The Mexican Asset Acquisition was accounted for as a business combination in accordance with Accounting Standards Codification 805, Business Combinations (“ASC 805”). The resulting goodwill arising from the acquisition was approximately $7,900,000 as of September 29, 2018. A significant portion of this goodwill is expected to be deductible by the Company for U.S. income tax purposes, and following a purchase of the noncontrolling interests by the Company, up to 100% of this goodwill would be expected to be deductible by the Company. Pro forma financial information for prior periods is not presented as the Company does not believe the Mexican Asset Acquisition to be material to our consolidated results. The results of operations from Landstar Metro and Landstar Servicios are presented as part of the Company’s transportations logistics segment. As it relates to the noncontrolling interests of Landstar Metro and Landstar Servicios, the Company has the option to purchase, and the minority equityholders have the option to sell, during the period commencing on the third anniversary of September 20, 2017, the closing date of the subscription by the minority equityholders (the “Closing Date”), and at any time after the fourth anniversary of the Closing Date, at fair value all but not less than all of the noncontrolling interests in Landstar Metro and Landstar Servicios. The noncontrolling interests are also subject to customary restrictions on transfer, including a right of first refusal in favor of the Company. |

| Share-based Payment Arrangements |
As of September 29, 2018, the Company had two employee equity incentive plans, the 2002 employee stock option and stock incentive plan (the “ESOSIP”) and the 2011 equity incentive plan (the “2011 EIP”). No further grants can be made under the ESOSIP. The Company also has a stock compensation plan for members of its Board of Directors, the Amended and Restated 2013 Directors Stock Compensation Plan (as amended and restated as of May 17, 2016, the “2013 DSCP”). 6,000,000 shares of the Company’s common stock were authorized for issuance under the 2011 EIP and 115,000 shares of the Company’s common stock were authorized for issuance under the 2013 DSCP. The ESOSIP, 2011 EIP and 2013 DSCP are each referred to herein as a “Plan,” and, collectively, as the “Plans.” Amounts recognized in the financial statements with respect to these Plans are as follows (in thousands):
Included in income tax benefits recognized in the thirty-nine-week periods ended September 29, 2018 and September 30, 2017 were income tax benefits of $80,000 and $310,000, respectively, recognized on disqualifying dispositions of the Company’s common stock by employees who obtained shares of common stock through exercises of incentive stock options. Also included in income tax benefits recognized in the thirty-nine-week periods ended September 29, 2018 and September 30, 2017 were excess tax benefits from stock-based awards of $2,046,000 and $868,000, respectively. As of September 29, 2018, there were 72,742 shares of the Company’s common stock reserved for issuance under the 2013 DSCP and 4,439,761 shares of the Company’s common stock reserved for issuance in the aggregate under the ESOSIP and 2011 EIP. Restricted Stock Units The following table summarizes information regarding the Company’s outstanding restricted stock unit (“RSU”) awards with either a performance condition or a market condition under the Plans:
During the thirty-nine-week period ended September 29, 2018, the Company granted RSUs with a performance condition and RSUs with a market condition, as further described below. Outstanding RSUs at both December 30, 2017 and September 29, 2018 include RSUs with a performance condition and RSUs with a market condition, as further described in the Company’s 2017 Annual Report on Form 10-K. RSUs with a performance condition granted on February 2, 2018 may vest on January 31 of 2021, 2022 and 2023 based on growth in operating income and pre-tax income per share from continuing operations attributable to Landstar System, Inc. and subsidiary as compared to the results from the 2017 fiscal year. On April 24, 2018, the Company granted 9,324 RSUs that vest based on a market condition. These RSUs may vest on June 30 of 2022, 2023 and 2024 based on the Company’s total shareholder return (“TSR”) compound annual growth rate over the vesting periods, adjusted to reflect dividends (if any) paid during such periods and capital adjustments as may be necessary. The maximum number of common shares available for issuance under the April 24, 2018 grant equals 150% of the number of RSUs granted. The fair value of this RSU award was determined at the time of grant based on the expected achievement of the market condition at the end of each vesting period. With respect to these RSU awards, the Company reports compensation expense ratably over the life of the award based on an estimated number of units that will vest over the life of the award, multiplied by the fair value of the RSU. Previously recognized compensation cost would be reversed only if the employee terminated employment prior to completing the requisite service period. The Company recognized approximately $11,303,000 and $2,254,000 of share-based compensation expense related to RSU awards in the thirty-nine-week periods ended September 29, 2018 and September 30, 2017, respectively. As of September 29, 2018, there was a maximum of $23.1 million of total unrecognized compensation cost related to RSU awards granted under the Plans with an expected average remaining life of approximately 3.3 years. With respect to RSU awards with a performance condition, the amount of future compensation expense to be recognized will be determined based on future operating results. Stock Options The following table summarizes information regarding the Company’s outstanding stock options under the Plans:
The total intrinsic value of stock options exercised during the thirty-nine-week periods ended September 29, 2018 and September 30, 2017 was $6,584,000 and $5,303,000, respectively. As of September 29, 2018, there was no unrecognized compensation cost related to non-vested stock options granted under the Plans. Non-vested Restricted Stock and Deferred Stock Units The following table summarizes information regarding the Company’s outstanding shares of non-vested restricted stock and Deferred Stock Units (defined below) under the Plans:
The fair value of each share of non-vested restricted stock issued and Deferred Stock Unit granted under the Plans is based on the fair value of a share of the Company’s common stock on the date of grant. Shares of non-vested restricted stock are generally subject to vesting in three equal annual installments either on the first, second and third anniversary of the date of the grant or the third, fourth and fifth anniversary of the date of the grant, or 100% on the first anniversary of the date of the grant. For restricted stock awards granted under the 2013 DSCP plan, each recipient may elect to defer receipt of shares and instead receive restricted stock units (“Deferred Stock Units”), which represent contingent rights to receive shares of the Company’s common stock on the date of recipient separation from service from the Board of Directors, or, if earlier, upon a change in control event of the Company. Deferred Stock Units become vested 100% on the first anniversary of the date of the grant. Deferred Stock Units do not represent actual ownership in shares of the Company’s common stock and the recipient will not have voting rights or other incidents of ownership until the shares are issued. However, Deferred Stock Units do contain the right to receive dividend equivalent payments prior to settlement into shares. As of September 29, 2018, there was $3,756,000 of total unrecognized compensation cost related to non-vested shares of restricted stock and Deferred Stock Units granted under the Plans. The unrecognized compensation cost related to these non-vested shares of restricted stock and Deferred Stock Units is expected to be recognized over a weighted average period of 2.3 years. |

The Tax Cuts and Jobs Act (the “Tax Reform Act”) permanently reduced the U.S. corporate income tax rate from a maximum of 35% to a flat 21% rate, effective January 1, 2018. The provisions for income taxes for the 2018 and 2017 thirty-nine-week periods were based on estimated annual effective income tax rates of 24.5% and 37.8%, respectively, adjusted for discrete events, such as benefits resulting from stock-based awards. The applicable effective income tax rates for the 2018 and 2017 thirty-nine-week periods were 23.1% and 34.5%, respectively. The effective income tax rate for the 2018 thirty-nine week period was higher than the statutory federal income tax rate primarily as a result of state taxes, the elimination of the performance-based compensation exception under Section 162(m) included in the Tax Reform Act and the meals and entertainment exclusion, partially offset by excess tax benefits realized on stock based awards and favorable adjustments recognized during the 2018 period relating to federal domestic production activities deductions and research and development credits during the thirteen-week period ended September 29, 2018. The effective income tax rate for the 2017 thirty-nine week period was lower than the statutory federal income tax rate primarily as a result of federal domestic production activities deductions and research and development credits recognized as discrete items during the thirteen-week period ended September 30, 2017, partially offset by the effect of state taxes and the meals and entertainment exclusion. |

Earnings per common share attributable to Landstar System, Inc. and subsidiary are based on the weighted average number of shares outstanding, including outstanding non-vested restricted stock and outstanding Deferred Stock Units. Diluted earnings per share attributable to Landstar System, Inc. and subsidiary are based on the weighted average number of common shares and Deferred Stock Units outstanding plus the incremental shares that would have been outstanding upon the assumed exercise of all dilutive stock options. The following table provides a reconciliation of the average number of common shares outstanding used to calculate earnings per common share attributable to Landstar System, Inc. and subsidiary to the average number of common shares and common share equivalents outstanding used to calculate diluted earnings per share attributable to Landstar System, Inc. and subsidiary (in thousands):
For both of the thirty-nine-week periods ended September 29, 2018 and September 30, 2017, no options outstanding to purchase shares of common stock were antidilutive. Outstanding RSUs were excluded from the calculation of diluted earnings per share attributable to Landstar System, Inc. and subsidiary for all periods because the performance metric requirements or market condition for vesting had not been satisfied. |

| Investments |
Investments include primarily investment-grade corporate bonds having maturities of up to five years (the “bond portfolio”) and money market investments. Investments in the bond portfolio are reported as available-for-sale and are carried at fair value. Investments maturing less than one year from the balance sheet date are included in short-term investments and investments maturing more than one year from the balance sheet date are included in other assets in the consolidated balance sheets. Management performs an analysis of the nature of the unrealized losses on available-for-sale investments to determine whether such losses are other-than-temporary. Unrealized losses, representing the excess of the purchase price of an investment over its fair value as of the end of a period, considered to be other-than-temporary, are to be included as a charge in the statement of income, while unrealized losses considered to be temporary are to be included as a component of equity. Investments whose values are based on quoted market prices in active markets are classified within Level 1. Investments that trade in markets that are not considered to be active, but are valued based on quoted market prices, are classified within Level 2. As Level 2 investments include positions that are not traded in active markets, valuations may be adjusted to reflect illiquidity and/or non-transferability, which are generally based on available market information. Any transfers between levels are recognized as of the beginning of any reporting period. Fair value of the bond portfolio was determined using Level 1 inputs related to money market investments and Level 2 inputs related to investment-grade corporate bonds, asset-backed securities and direct obligations of government agencies. Unrealized losses, net of unrealized gains, on the investments in the bond portfolio were $1,299,000 and $223,000 at September 29, 2018 and December 30, 2017, respectively. The amortized cost and fair values of available-for-sale investments are as follows at September 29, 2018 and December 30, 2017 (in thousands):
For those available-for-sale investments with unrealized losses at September 29, 2018 and December 30, 2017, the following table summarizes the duration of the unrealized loss (in thousands):
The Company believes unrealized losses on investments were primarily caused by rising interest rates rather than changes in credit quality. The Company expects to recover the amortized cost basis of these securities as it does not intend to sell, and does not anticipate being required to sell, these securities before recovery of the cost basis. For these reasons, the Company does not consider the unrealized losses on these securities to be other-than-temporary at September 29, 2018. |

Short-term investments include $40,203,000 in current maturities of investments held by the Company’s insurance segment at September 29, 2018. The non-current portion of the bond portfolio of $71,489,000 is included in other assets. The short-term investments, together with $29,194,000 of non-current investments, provide collateral for the $62,457,000 of letters of credit issued to guarantee payment of insurance claims. As of September 29, 2018, Landstar also had $34,370,000 of additional letters of credit outstanding under the Company’s Credit Agreement. During 2017, the Company incorporated each of Landstar Metro and Landstar Servicios. On September 20, 2017, Landstar Metro acquired substantially all of the assets of the asset-light transportation logistics business of Fletes Avella, S.A. de C.V., a Mexican transportation logistics company. In connection with the Mexican Asset Acquisition, individuals affiliated with the seller subscribed in the aggregate for equity interests in Landstar Metro and Landstar Servicios and, as of September 29, 2018, own in the aggregate approximately 21% of the equity interests of each of them. As it relates to the noncontrolling interests of Landstar Metro and Landstar Servicios, the Company has the option to purchase, and the minority equityholders have the option to sell, during the period commencing on the third anniversary of September 20, 2017, the closing date of the subscription by the minority equityholders (the “Closing Date”), and at any time after the fourth anniversary of the Closing Date, at fair value all but not less than all of the noncontrolling interests in Landstar Metro and Landstar Servicios. The noncontrolling interests are also subject to customary restrictions on transfer, including a right of first refusal in favor of the Company. The Company is involved in certain claims and pending litigation arising from the normal conduct of business. Many of these claims are covered in whole or in part by insurance. Based on knowledge of the facts and, in certain cases, opinions of outside counsel, management believes that adequate provisions have been made for probable losses with respect to the resolution of all such claims and pending litigation and that the ultimate outcome, after provisions therefor, will not have a material adverse effect on the financial condition of the Company, but could have a material effect on the results of operations in a given quarter or year. |

Landstar provides for the estimated costs of self-insured claims primarily on an actuarial basis. The amount recorded for the estimated liability for claims incurred is based upon the facts and circumstances known on the applicable balance sheet date. The ultimate resolution of these claims may be for an amount greater or less than the amount estimated by management. The Company continually revises its existing claim estimates as new or revised information becomes available on the status of each claim. Historically, the Company has experienced both favorable and unfavorable development of prior years’ claims estimates. The following table summarizes the effect of the increase in the cost of insurance claims resulting from unfavorable development of prior year self-insured claims estimates on operating income, net income attributable to Landstar System, Inc. and subsidiary and earnings per share attributable to Landstar System, Inc. and subsidiary amounts in the consolidated statements of income for the thirty-nine-week and thirteen-week periods ended September 29, 2018 and September 30, 2017 (in thousands, except per share amounts):

Adoption of New Accounting Standards In May 2014, the FASB issued ASU 2014-09. ASU 2014-09 is a comprehensive revenue recognition model requiring a company to recognize revenue to depict the transfer of goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods or services. The standard requires more detailed disclosures to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. ASU 2014-09 became effective for us December 31, 2017 and permits either a full retrospective or a modified retrospective transition approach. The Company adopted ASU 2014-09 for our transportation services using the modified retrospective method. The adoption of this standard has changed the timing of revenue recognition for most of our transportation business from at delivery to over the transit period as the performance obligation is completed. The Company recognized the cumulative effect of initially applying the new revenue standard as an adjustment to the opening balance of retained earnings. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. The Company had no material contract assets, contract liabilities or deferred contract costs recorded on the consolidated balance sheets at December 30, 2017 or September 29, 2018. During the thirty nine weeks ended September 29, 2018, revenue generated by BCO Independent Contractors, Truck Brokerage Carriers and railroads represented approximately 44%, 49% and 3%, respectively, of the Company’s consolidated revenue. Collectively, revenue generated by air and ocean cargo carriers represented approximately 2% of the Company’s consolidated revenue in the thirty-nine-week period ended September 29, 2018. Included in truck transportation revenue generated by BCO Independent Contractors and Truck Brokerage Carriers during the thirty-nine-week period ended September 29, 2018 was $2,086,523,000 hauled via van equipment, $1,039,784,000 hauled via unsided/platform equipment and $76,448,000 of less-than-truckload. As of September 29, 2018, the Company had no material remaining performance obligations. The Company does not expect the adoption of the new standard to have a material impact on its net income in future periods.
The cumulative effect of the changes made to our consolidated December 31, 2017 balance sheet for the adoption of ASU 2014-09 was as follows (in thousands):
In accordance with the new revenue standard requirements, the impact of adoption on our consolidated income statement and balance sheet was as follows (in thousands):
Accounting Standards Issued But Not Yet Adopted In February 2016, the FASB issued Accounting Standards Update 2016-02 – Leases (“ASU 2016-02”). ASU 2016-02 requires a company to recognize a right-of-use asset and lease liability for the obligation to make lease payments measured at the present value of the lease payments for all leases with terms greater than twelve months. Companies are required to use a modified retrospective transition approach to recognize leases at the beginning of the earliest period presented. ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, and interim periods therein, and early adoption is permitted. ASU 2016-02 is not expected to have a material impact on the Company’s financial statements. In June 2016, the FASB issued Accounting Standards Update 2016-13– Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires measurement and recognition of expected versus incurred credit losses for financial assets held. ASU 2016-13 is effective for annual periods beginning after December 15, 2019, and interim periods therein. The Company is currently evaluating the impact of ASU 2016-13 on its financial statements. |

Significant Accounting Policies (Policies) |
9 Months Ended |
|---|---|
Sep. 29, 2018 | |
| Revenue Recognition | Revenue Recognition The nature of the Company’s freight transportation services and its performance obligations to customers, regardless of the mode of transportation used to perform such services, relate to the safe and on-time pick-up and delivery of a customer’s freight on a shipment-by-shipment basis. Landstar customers are typically invoiced on a shipment-by-shipment basis at a pre-defined rate, payable thirty to sixty (30-60) days after the customer’s receipt of such invoice. Payment terms to customers do not contain a significant financing component and the amount owed by the customer does not contain variable terms, embedded or otherwise. We have determined that revenue recognition over the transit period provides a faithful depiction of the transfer of services to the customer as our obligation for which we are primarily responsible for fulfilling is performed over the transit period. Accordingly, transportation revenue billed to a customer for the physical transportation of freight and related direct freight expenses are recognized on a gross basis over the transit period as the performance obligation is satisfied. The Company determines the transit period for a given shipment based upon the pick-up date and the delivery date, which may be estimated if delivery has not occurred as of the reporting date. Determining the transit period and how much of it has been completed as of a given reporting date may therefore require management to make judgments that affect the timing of revenue recognized. With respect to shipments with a pick-up date in one reporting period and a delivery date in another, the Company recognizes such transportation revenue based on relative transit time in each reporting period. A days in transit output method is used to measure the progress of the performance of the Company’s freight transportation services as of the reporting date and a portion of the total revenue that will be billed to the customer once a load is delivered is recognized in each reporting period based on the percentage of total transit time that has been completed at the end of the applicable reporting period. |

- Definition Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction. Reference 1: http://fasb.org/us-gaap/role/ref/otherTransitionRef
