For-hire transportation consists of transportation services provided on a fee basis to industries and the public. These services are provided by businesses such as railroads, transit agencies, common carrier trucking providers, and pipeline companies.
In-house transportation consists of the services provided by nontransportation industries for their own use. It includes privately owned and operated vehicles of all body types, used primarily on public rights of way, and the supportive services to store, maintain, and operate those vehicles.
