Segment Information [Abstract] |
Segment Information | Segment Information We provide truckload services across the United States (U.S.) and parts of Canada. These truckload services are primarily asset-based transportation services in the dry van truckload market. We also offer truckload temperature-controlled transportation services, although not significant to our operations. Our Chief Operating Decision Maker oversees and manages all of our transportation services, on a combined basis, including previously acquired entities. As a result of the foregoing, we have determined that we have one segment, consistent with the authoritative accounting guidance on disclosures about segments of an enterprise and related information.
