Speed limits for thoroughfares and major collector streets are established based upon recognized engineering criteria related to roadway design. Some of the variables include street width, lane width, sight distance, number and type of driveways, and vertical/horizontal alignments. Changing conditions may dictate a review of posted speed limits from time to time. NCDOT is involved in the process on most thoroughfare streets. By State statute, streets within the Charlotte city limits have a speed limit of 35 mph unless otherwise posted. That includes neighborhood streets.
By authority of the Director of Transportation or designee, as stated in NCGS 20-141, the posted speed limit for streets classified as local streets is 25 mph. Streets classified as minor or major collectors by the Charlotte Regional Transportation Planning Organization (CRTPO) are eligible for 25 mph posted speed limit reduction unless they are designated as an Avenue, Boulevard, or Parkway on the Urban Street Design Guidelines (USDG) street classification map.
In cases where new streets are added to the centerline map or where street classifications are downgraded from a higher classification in the CRTPO, the USDG, or the Streets Map, CDOT will apply the respective posted speed limit if it meets the definitions in this section.
