a. Road Classifications. Roads on small-scale maps are classified as--
(1) Dual or super highways.
(2) Main roads.
(3) Secondary roads.
(4) Other roads.
(5) Tracks or trails.
b. Main Roads. Main roads are those which serve as the main thoroughfares between the important populated places of an area. Well alined roads of a substantial width and surface which connect a number of populated places, and cross-country roads which form a direct route connecting with roads and trails leading to important features are included in this category. Main roads are generally hard-surfaced except in areas with poor road systems.
c. Secondary Roads. Secondary roads include those roads connecting the minor cities and towns of an area. A road connecting two main roads, at least one of which is higher in classification than the connecting road, is included in this category. In comparison with main roads, secondary roads have less reported use and less substantial construction, and are generally loose-surfaced roads.
d. Other Roads. Included in this category are local community roads serving the villages and settlements of an area. Also included are those connecting roads important to the communications network but obviously of a lower classification than the secondary roads. Such roads may be loose-surfaced or dirt roads.
e. Tracks or Trails. Tracks and trails are symbolized alike. Both normally are shown only in areas of sparse culture where they supply the only means of communication. Minor tracks and trails are omitted. Included in this category are winter roads and caravan routes. Normally, the roadway is natural with little or no improvements.
f. Symbols. The following contain the approved symbols for roads on small-scale maps.
