An exception currently to the USA Roads standard is North Carolina state highways. North Carolina has numbered state highways from Controlled Access Freeways down to Alleys. Because of this North Carolina strictly uses Functional Classification to set road types for state roads and below.

US Highways and Interstates will continue to follow Waze standards

Road Names

NOTE:

Please label all state highways with the following format:NC-XX or NC-XXX
This includes both Primary Names and Alternate street names.

See Road names/USA as a general rule.

NCDOT assigns every state maintained road a State Rd number of 4 digits or more. The State Rd number should be named "SR XXXX" it is usually an alternate names.
SR numbers can be found using the NCDOT SR Lookup Site
NC does not use County Rd numbers. Change any found to State Rd format "SR XXXX".

Road Function Class

See Road types/USA as a general rule.
We have also incorporated the NC Functional Class Map into are road classification system:

This should be the first step in determining how a road should be type. The list below are minimums (e.g. a State Highway would be at a minimum a minor highway. It could also be a major highway or freeway depending on functional class)

Freeway - Interstates and all other roads with no at grade intersections.
Major Highway - US Highways, Interstates that have at grade intersections.
Minor Highway - State Highways, US Business Highways.
Primary Street - State Business Highways.

If the road is not defined as one of the above then please use the functional class to determine what type to qualify the road as.

Using the NC Functional Class Map: The NC functional Class Map is divided into 9 road type classifications. Most road classifications will minimally be defined by the above criteria. For all other roads that do not fit into that criteria please use the references below:

Functional Class Type - Waze Type

Interstate - Freeway
Other Freeway - Freeway
Other Principal Arterial - Major Highway
Minor Arterial - Minor Highway
Major Collector - Primary Street
Minor Collector - Primary Street
Local - Street

Contact the Area Manager or State Manager if you feel there is an exception to these rules. Consistency is key do not change a road type for routing sake or to make it appear on the map at a higher speed. Also, do not switch road types every few segments just because the functional class does (Contact the AM or SM for help).

Function Class Quick Reference Chart

Refer to this chart to determine the road type of a given paved public road based on the North Carolina functional class.

To use this chart, first determine the functional class of a road, and whether it is a signed, numbered highway in a particular highway system.

Where the column for the road's highway system and the row for the road's North Carolina functional class meet, you will find the proper road type for that particular road.

A number of examples are given below the chart.

		Highway Systems
		Interstate	Interstate Business Loop/Spur	US Hwy (incl. some special routes)	US Hwy BUS, SPUR, LOOP	State Hwy (incl. some special routes)	State Hwy BUS, SPUR^[a], LOOP	Locally-maintained
	example	I-95 N	I-95 Business	US-301	US-301 Business	NC-87	NC-87 Business	Robertson St
N C F u n c t i o n a l C l a s s	Interstate^[b]	Fw	n/a	n/a	n/a	n/a	n/a	n/a
	Other Freeway^[c]	n/a	Fw	Fw	Fw	Fw	Fw	Fw
	Other Principal Arterial^[d]	n/a	Major	Major	Major	Major	Major	Major
	Minor Arterial^[e]	n/a	Major	Major	Minor	Minor	Minor	Minor
	Major Collector	n/a	Major	Major	Minor	Minor	PS	PS
	Minor Collector	n/a	Major	Major	Minor	Minor	PS	PS
	Local/not mapped	n/a	Major	Major	Minor	Minor	PS	Street

^a When a state highway "SPUR" route is used to connect a state highway with another state highway, a US highway, or an Interstate (i.e., when it is used as a connector/CONN route), use the first state highway column.

^b Also known as Principal Arterial - Interstate.

^c Also known as Principal Arterial - Freeway.

^d Also known as Principal Arterial.

^e Also known as Other Arterial.

For example,

An Interstate Business Loop classified as a Minor Arterial is a Major Highway .
A US Highway classified as a Minor Arterial is a Major Highway .
A US Highway Spur route classified as a Minor Arterial is a Minor Highway .
A State Highway classified as an Other Freeway is a Freeway .
A State Highway classified as a Collector is a Minor Highway .
A locally-maintained road classified as an Other Principal Arterial is a Major Highway .
A locally-maintained road classified as a Collector is a Primary Street .
