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, airlines, and pipeline companies.

In-house transportation consists of the services provided by non-transportation industries for their own use. It includes privately owned and operated vehicles used primarily on public rights of way, as well as the supportive services to store, maintain, and operate those vehicles.
