→Editor Discretion: Wordsmith from original import of forum proposal.
Always exercise caution when mapping roads found on an MVUM, particularly through roads! MVUMs may be inaccurate or out of date, and roads may vary in quality over seasons depending on the climate (rain/snow). Particularly, some roads in Maintenance Level 3 may have attributes that are closer to Off-Road / Not Maintained than Street.
Before mapping a road, compare the MVUM with recent aerial imagery (and with Street View and anecdotal visitor reports if possible) and verify that the road remains drivable. Vegetation growing not just between the tracks but in them often signifies an abandoned road. Some roads may be permanently closed with boulders or solid fencing placed at their endpoints. Don't map these, even if they appear on the MVUM! Mapping or completing abandoned roads may have severe unintended consequences. For example:
*If the road is mapped as a through road, even one with high penalties, Waze may attempt to route emergency traffic over it when primary roads have been closed. Waze could endanger lives by offering impassable roads as escape routes!
Ideally editors responding in an emergency will identify and close all relevant through roads, but the more roads involved, the greater the response effort, and the more likely something will be missed.
*Any road's presence on the Waze display could encourage Wazers to try it and potentially get stuck.
Even if not used for routing, mapped roads serve an orientation purpose. Drivers passing a "road" that is shown on their display but no longer looks like a road (overgrown, permanently fenced off or blocked, etc.) may be disoriented by the inconsistency.
Using discretion when deciding whether and how to map Forest Service roads can dramatically improve Wazers' driving experience.
