| Segment Reporting [Text Block] |
| Note 4. | Segment Information |
We have four reportable segments:
| ● | Expedited: The Expedited reportable segment primarily provides truckload services to customers with high service freight and delivery standards, such as 1,000 miles in 22 hours, or 15-minute delivery windows. Expedited services generally require two-person driver teams on equipment either owned or leased by the Company. |
| ● | Dedicated: The Dedicated reportable segment provides customers with committed truckload capacity over contracted periods with the goal of three to five years in length. Equipment is either owned or leased by the Company. The Dedicated reportable segment also provides shuttle and switching services related to shuttling containers and trailers in or around freight yards and to/from warehouses for Dedicated customers. |
| ● | Managed Freight: The Managed Freight reportable segment includes our brokerage and transport management services (“TMS”). Brokerage services provide logistics capacity by outsourcing the carriage of customers’ freight to third parties. TMS provides comprehensive logistics services on a contractual basis to customers who prefer to outsource their logistics needs. |
| ● | Warehousing: The Warehousing reportable segment provides day-to-day warehouse management services to customers who have chosen to outsource this function. The Warehousing reportable segment also provides shuttle and switching services related to shuttling containers and trailers in or around freight yards and to/from warehouses for Warehousing customers. |
The Company's chief operating decision maker ("CODM"), the Chief Executive Officer, evaluates the operating results through reportable segment operating income, which includes certain corporate overhead allocations directly attributable to each of the segments. We do not report our intersegment revenues by segment to our CODM and do not believe they are a meaningful metric for evaluating the performance of our reportable segments.
Each segment uses certain shared infrastructure and each segment is presented with its direct costs and an allocation of certain shared overhead costs. Insurance and claims expense is charged to the segments based on their historic claims experience and an allocation of current insurance premiums.
The CODM uses operating income for each segment in the annual budget and strategic planning process. The CODM considers budget-to-actual variances on a quarterly basis as well as month-over-month variances when making decisions about the allocation of operating and capital resources to each segment. The CODM also uses segment operating income for evaluating pricing strategy, to assess the performance of each segment by comparing the results of each segment with one another, and in determining the compensation of certain employees.
The following table summarizes our total revenue by our four reportable segments, as used by our CODM in making decisions regarding allocation of resources etc., for the three and six months ended June 30, 2026 and 2025:

| (1) | The CODM does not receive fuel surcharge revenue and fuel expense individually, but is provided with fuel expense less fuel surcharge revenue (other than the fuel surcharge revenue we reimburse to independent contractors and other third parties which is included in purchased transportation), which we refer to as net fuel expense. The CODM uses net fuel expense to measure the effectiveness of our fuel surcharge program. |
| (2) | Other represents indirect costs not directly attributable to any one reportable segment, amortization of intangible assets, and contingent consideration liability adjustments to match the information our CODM uses to evaluate the operating results of our reportable segments. |
Balance sheet data by reportable segment is not maintained by the Company.
