Colo. Rev. Stat. § 40-1.1-101
In order to promote improved transportation for the elderly, for persons with disabilities, and for the residents of rural areas and small towns through an expanded and coordinated transportation network, the general assembly hereby declares it to be the policy of the state to legally define and to recognize people service transportation and volunteer transportation as separate but contributing components of the transportation system. Therefore, it is the policy of the state to remove barriers to low-cost people service transportation and volunteer transportation. For this purpose, transportation systems meeting the criteria prescribed in this article will not be classified as public utilities or as any form of carrier subject to regulation by the commission but as people service transportation and volunteer transportation subject to appropriate regulation and administration.
