The answer is "To direct drivers to specific roads"

The traps in the wrong answers
A. To mark spots where pedestrians cross
Pedestrian crossings use yellow-green warning signs, not route markers. This answer places the pedestrian-crossing sign under the wrong category header.
B. To warn of construction zones ahead
Construction warnings appear on orange signs, not route markers. This answer blends the general idea of a highway sign with orange construction signage.
D. To display the distance to the next town
Distance information appears on green mileage signs, not route markers. This answer merges two guide-sign functions that often appear side by side on a highway.
