While there has been a little bit of confusion regarding the road types based on common sense. If you read the wiki, Nevada uses the DOT guidelines for the purpose of navigation routing and not based on the given name of the road. Nevada has a lot of graded gravel roads which are technically considered primary roads within WME. Before changing a road type to anything less than that which is assigned in the NV DOT functional classification check with an Area Manager, State Manager, Regional Coordinator, or Country Manager within the Nevada Forum.

Local naming variations

Nevada uses NV-##, and NV-##X for all state routes and their spurs, loops, etc. (e.g. NV-89, NV-17M). When working on an area, if you encounter a road with the old SR-## naming, please take the time to change that name to reflect the NV-## name. This includes alternate names, if you notice them.

It should be noted that while we use the NV-xxx road designation for better clarity for drivers using Waze, the Nevada Department of Transportation does not use it. When you are verifying a state route number against an official source, you'll see "SR-89" instead of "NV-89", for example. This is ok, don't let that cause you concern. Just go ahead and use the NV-xxx designation (using the official route/highway number) when setting/correcting a state route number.

Functional Classifications

Nevada is following the Functional Classification (FC) system for the USA.

The following resource can help to determine the FC for some of the roads in Nevada:

Lock Levels

In Nevada we have a set minimum standard for locking roads based on segment type. Any road of a certain segment type must be locked at least to the rank (level) in the chart below. Roads may be locked higher for protection and special situations (areas with construction, tricky design, frequent mistakes, imaging inaccuracies, and the like), but should not be locked lower.

A great time to implement these locks is while bringing the road types of an area into compliance with the current US road type standards (FC and highway systems). Lock the roads based on type after they've been set to current US road type standards.

Nevada Minimum Locking Rank Standard
Segment Type Urban Areas  Rural Areas
 Freeway  5 4
 Ramp  5 4
 Major Highway  3
 Minor Highway  2
 Primary Street  2
 Street  Automatic (1)
 Private Road  Automatic (1)
 Parking Lot Road  Automatic (1)
 • • • • Ferry • • • •   5
 |-|-|-|-|-|-|-|-|-| Railroad |-|-|-|-|-|-|-|-|-|  2

NOTE: Streets directly involved in the Las Vegas Strip area should be minimum locked at one rank (level) higher than the above minimums, to protect that vital traffic corridor.

Please note that the above lock levels are subject to change, pending final approval of those levels.
