What is the function of reference post markers on Nebraska highways?

Reference post markers on Nebraska highways are utilized primarily to serve as reference points for drivers. These markers are strategically placed along the roadways to provide distance information to drivers and assist them in navigation. They help in identifying specific locations, indicating the distance to the nearest city or town, and enhancing overall situational awareness on the road.

While they do not indicate speed limits, scenic views, or exit points, which are the focus of other signage, reference post markers are crucial for drivers for assessing their position on the highway and for emergency services to quickly respond to incidents by having identifiable locations.
