Functional Classification
Idaho follows the Functional Classification (FC) system for both state and non-state roads. There are currently 2015 and 2025 classifications available. At this time, we are following the 2015 classifications.
Idaho "2025" Functional Classification Map has both 2015 and 2015 functional classifications available as overlays. The 2015 map is current-day (2015). The 2025 overlay has some additions but also some current-day functionally classified streets are no longer. Also, there are planned streets for 2025 which are not built yet and so cannot be added to the Waze map.
Refer to the Functional Classification Quick Reference Chart to determine the correct Waze road type. Remember that a US Highway or Interstate business route in urban areas where streets are named locally, that an alternate street designation may be key to determining the correct Waze road type.
