37 Miss. Code R. § 1-6101-53002-301
The MDOT uses the terms "non-urbanized and rural areas" synonymously to mean any area outside an urbanized area, as designated by the Bureau of the Census. An urbanized area consists of a core area and the surrounding densely populated area with a population of 50,000 or more, with boundaries fixed by the Census Bureau or extended by state and local officials. The goal of Section 5310 is for the primary purpose of providing transportation to elderly and/or disabled persons. In addition to specific clients, transportation services may be made available to other elderly and disabled persons on a space available basis. Section 5310 vehicles may also serve the transportation needs of general public passengers on an incidental basis. The incidental basis refers to services that do not interfere with transportation services designed to meet the specific needs of elderly persons or persons with disabilities.
