§ 70.08 UNLAWFUL PASSING.
   (A)   Whenever, pursuant to division (B) below, appropriate traffic control devices have been installed that clearly indicate that no passing is allowed on a portion of any street, no driver of a vehicle may overtake and pass another on any portion of any street so restricted (Note: G.S. § 20-150(e) makes it unlawful to pass contrary to signs posted by the State Department of Transportation).
   (B)   The Administrator may install appropriate traffic control devices to indicate that no passing is allowed whenever and wherever he or she determines that passing would be unsafe on that portion of a street because:
      (1)   The street intersects with another street;
      (2)   The slope or grade of the street is such or the street curves to such an extent that a driver's view is obstructed within a distance of 500 feet; or
      (3)   Any other conditions exist making passing hazardous.
