The secondary road system within a county for the purpose of this Subchapter consists of those roads maintained by the Department of Transportation that do not carry "NC" or "US" numbers and are outside the boundary of any incorporated municipality.  In the development of secondary road plans, these roads fall into several categories which are defined as follows:

(1)           Principal County Routes.  These routes serve as the backbone of the rural transportation network within a county.  Their major purpose is to move local traffic to community and recreational centers, shopping and industrial areas, to urban areas within the county and to connect together the other secondary roads with the primary highway system.  In addition, they serve abutting residential, farming, business and industrial property.

(2)           County Roads.  These roads have as their primary purpose serving abutting residential, farming, business, and industrial use. They also carry small to moderate volumes of traffic moving to the principal county routes and the primary highway system.  Their dual function of serving traffic and abutting property is variable depending upon their importance as a through route or connecting link.

(3)           Subdivision Streets.  A subdivision street is considered to be a street or road which has been dedicated to the public to provide ingress and egress to lots or parcels which have been laid out for the purpose of providing home sites by a person or firm hoping to profit by the sale of such parcels.  These lots or parcels are of insufficient size to be used primarily for farming purposes.  A subdivision street is primarily for the use and convenience of the abutting property owners and not the general traveling public.

(4)           Collector Roads.  Collector roads channel traffic in subdivisions from side roads.  They also provide access from other state-maintained roads.
