A primitive road is a minor road system, used for travel or transportation that is generally not maintained or paved.[1] Primitive roads primarily occur in rural farmlands, deserts, or forests rather than in developed areas.

## Classification

[edit]

### United States

[edit]

A primitive road can be classified if it meets the following criteria:

1. Is not classified as part of the area's primary road system
2. Has an average annual daily traffic of one hundred or fewer vehicles.[2]
3. Is typically made as non-paved gravel road or dirt road driveway

In the United States most of these roads are maintained by local governments and signed as county highways.
