With no explanation, label text_A→text_B with either "DON'T KNOW", "NO" or "YES".
text_A: Leaving Albuquerque to the north, I-25 curves to the northeast as it approaches Santa Fe. Continuing 'northbound' at Santa Fe, I-25 heads southeast for approximately traveling through the Santa Fe National Forest and crossing Glorieta Pass (elevation). It turns north again at Blanchard toward Las Vegas. The highway maintains a north and northeast orientation as it leaves New Mexico traversing Raton Pass () and enters Colorado. From Santa Fe to Trinidad, Colorado, I-25 approximates part of the route of the Santa Fe Trail. Although US 85 lacks any signage, it is aligned with I-25 for its entire length within the state.
text_B: If you were to travel across New Mexico using only US highway 85, would the only signs you saw on the side of the road be for advertising and/or other private purposes, and not related to the road itself?
YES.
