INSERT the following paragraphs:
Standard:
00A If Table 2C-5 indicates that a horizontal alignment
					 sign (see Figure 2C-1) is required, recommended, or allowed, the sign installed
					 in advance of the curve shall be a Curve (W1-2) sign unless a different sign is
					 required, recommended, or allowed by the provisions of this Section.
00B A Turn (W1-1) sign shall be used instead of a Curve
					 sign in advance of curves that have advisory speeds of 30 mph or less (see
					 Figure 2C-2).
Option:
00C Where the legal speed limit is 30 MPH and the advisory
					 speed is higher than the speed limit, a horizontal alignment sign, if used, may
					 be either the Turn (W1-1) or Curve (W1-2) sign.
Guidance:
00D Signs are not required, and normally should not be
					 used, for curves having advisory speeds more than five mph above the legal and
					 85th-percentile speeds.
Standard:
00E Where the advisory speed is less than the legal speed
					 limit, the horizontal alignment sign shall be supplemented with an Advisory
					 Speed plaque (see Section
					 2C.08).
00F Where the advisory speed is greater than the legal
					 speed limit, an Advisory Speed plaque shall not be used.
Option:
00G Where the advisory speed is equal to the legal speed
					 limit, an Advisory Speed plaque may be used.
00H If the change in horizontal alignment is 135 degrees or
					 more, the Hairpin Curve (W1-11) sign (see Figure 2C-1) may be used instead of a
					 Curve or Turn sign. If the change in horizontal alignment is approximately 270
					 degrees, such as on a cloverleaf interchange ramp, the 270-degree Loop (W1-15)
					 sign (see Figure 2C-1) may be used instead of a Curve or Turn sign.
Guidance:
00I When the Hairpin Curve sign or the 270-degree Loop sign
					 is installed and the advisory speed is equal to or 5 MPH above the legal speed
					 limit, either a One-Direction Large Arrow (W1-6) sign or Chevron Alignment
					 (W1-8) signs should be installed on the outside of the curve.
Standard:
00J Curves in the same direction separated by 200 feet or
					 more shall be signed separately, except as provided elsewhere in this section.
					 Curves in opposite directions separated by more than 600 ft shall be signed
					 separately.
Option:
00K Two curves in the same direction separated by less than
					 200 feet may be considered a single curve having an advisory speed equal to the
					 lower of the two curves.
Support:
00L Separate signing of two curves in the same direction
					 separated by less than 200 feet is preferable where the first curve is long and
					 has an advisory speed higher than the second curve.
00M Separate signing of two curves in opposite directions
					 separated by 600 feet or less is preferable where the first curve is long and
					 has an advisory speed higher than the second curve. Separate signing may also
					 be preferable where the distance between curves is more than 400 ft.
Option:
00N The Winding Road sign may be used where warning is
					 required for a series of three or more curves, generally alternating in
					 direction and separated by distances of 600 feet or less.
Standard:
00O Where a Winding Road sign is needed, the W1-5L sign
					 shall be used where the first curve in the series is to the left, and the W1-5R
					 sign shall be used where the first curve in the series is to the right.
00P The advisory speed used with a Reverse Turn (W1-3),
					 Reverse Curve (W1-4), or a Winding Road (W1-5) sign shall be the lowest
					 advisory speed of any curve in the series, except as provided below.
Option:
00Q Each Winding Road sign in advance of, and within, the
					 curve series may be supplemented with a Next Distance (W16-4p) plaque (see
					 Section
					 2C.55) stating the distance to the end of the series.
00R Within the series of curves, appropriate Turn, Curve,
					 Reverse Turn, and Reverse Curve signs may be used for individual curves, or
					 curve combinations, having advisory speeds significantly lower than the other
					 curves in the series.
Guidance:
00S An appropriate Turn, Curve, Reverse Turn, or Reverse
					 Curve sign should be placed following an individually-signed curve, or curve
					 combination, to provide warning for the remaining curves in the series.
					 Advisory speeds for the portions of the series which precede and follow any
					 individually-signed curve, or curve combination, should be determined
					 independently.
