MUTCD/IM

Series IM of the MUTCD is for incident management area signs. Whereas a regulatory sign appears the same inside and outside an incident management area, a warning sign has a fluorescent pink background in an incident management area instead of the usual yellow or the orange in a construction zone. Otherwise, the entirety of Series IM is identical to Series W and Series CW. 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 disaster areas. For routing purposes, short-term incidents are more reliably and efficiently tracked in incident management systems along with real-time traffic congestion data.
