Leases [Abstract]
Operating Leases	Operating Leases Rent expense for operating leases for revenue equipment that resulted from our IDC acquisition was $0.3 million and $1.8 million for the three months ended March 31, 2019 and March 31, 2018, respectively. These operating leases terminated March 31, 2019. These expenses were included in rent and purchased transportation in the consolidated statements of comprehensive income. We currently lease certain terminal facilities under operating leases and we expect these current leases to expire in 2019 and 2020. One of these leases contains a purchase option which we have exercised and expect to purchase during 2019. We are responsible for all taxes, insurance, and utilities related to the terminal leases. Rent expenses for terminal facilities were $0.8 million (including related-party rental payments totaling zero), for the three months ended March 31, 2019. Rent expenses for terminal facilities were $1.3 million (including related-party rental payments totaling $0.3 million), for the three months ended March 31, 2018. Historically, a portion of these leases were with limited liability companies, whose members include one of our board members and a commercial tractor dealership whose owners include one of our board members. The related-party rental payments were entered into as a result of a previous acquisition, although these leases ended in November, 2018.

These operating leases terminated March 31, 2019. These expenses were included in rent and purchased transportation in the consolidated statements of comprehensive income.

We currently lease certain terminal facilities under operating leases and we expect these current leases to expire in 2019 and 2020. One of these leases contains a purchase option which we have exercised and expect to purchase during 2019. We are responsible for all taxes, insurance, and utilities related to the terminal leases. Rent expenses for terminal facilities were $0.8 million (including related-party rental payments totaling zero), for the three months ended March 31, 2019. Rent expenses for terminal facilities were $1.3 million (including related-party rental payments totaling $0.3 million), for the three months ended March 31, 2018.
