MUTCD/Utah/WS

Series WS of the Utah MUTCD is for warning signs. The following tables display only the signs specific to the Utah MUTCD; consult MUTCD/W for warning signs in the national standard.

Temporary warning signs

This series includes warning signs for temporary traffic control zones, i.e., construction zones, as well as for incident management areas. Whereas a regulatory sign appears the same inside and outside a construction zone, a temporary warning sign has an orange background instead of the usual yellow, and an incident management warning sign has a fluorescent pink background. Incident management area signs are not to be confused with the emergency management signs of Series EM.

In general, OpenStreetMap only maps long-term closures and construction sites. For routing purposes, short-term construction is more reliably and efficiently tracked in incident management systems along with real-time traffic congestion data. However, if a temporary warning sign happens to be posted on a long-term basis for some reason, you can map it as you would map a permanent warning sign. If you map the temporary traffic sign as a node, use a W code but add colour=orange or pink to the node.
