DELETE Paragraph 04.
INSERT the following paragraphs:
Guidance:
00A The use of Intersection Warning signs should be limited to intersections where there is insufficient visibility, or where motorists must exercise more than normal caution.
Support:
00B Sight distance between vehicles approaching and vehicles waiting at an intersection is a basic consideration in determining the need for an Intersection Warning sign. However, accident experience and other factors, such as unusual geometry, are also important considerations. Engineering judgment should prevail in determining the need for Intersection Warning signs.
Guidance:
00C Figure 2C-101 should be used as a guide in deciding if an Intersection Warning sign should be installed. It expresses the significance of intersection visibility in terms of sight distance along the highway and 85th percentile approach speed.
Standard:
00D A plotted point in the red area below the lower curve indicates an intersection approach with critically limited sight distance, and an Intersection Warning sign shall be used except at otherwise specified in this section.
Guidance:
00E A plotted point in the white area above the upper curve indicates an intersection approach with more than adequate sight distance, and, except where unusual conditions require otherwise, an Intersection Warning sign should not be used.
Option:
00F A plotted point in the yellow area between the upper and lower curves indicates an intersection approach that has less than desirable sight distance, but is not critically limited, and an Intersection Warning sign may be used where other factors indicate a need.
Option:
01A The Side Road (NYW2-8) symbol sign (see Sign Drawing SD-W2) may be installed in advance of an intersection where the side road enters the main roadway at an acute angle.
Option:
03A An educational plaque (see Figure 2C-9) with the legend ROUNDABOUT (W16- 17P) may be mounted below a Circular Intersection symbol sign.
Standard:
03B The TRAFFIC CIRCLE (W16-12p) plaque shall not be used on an approach to a roundabout in New York.
Guidance:
08A Intersection Warning signs should not ordinarily be used on intersection approaches where Junction or Advance Route Turn assemblies (see Sections 2D.30 and 2D.31) or Destination signs (see Section 2D.37) are used.
Guidance:
09A The W2-1 sign should be used where two roads intersect from opposite sides and the distance between the intersections is less than 30 feet. The W2-7 sign should be used where the distance between intersections is 30 to 250 feet. Where the distance between the intersections is more than 250 feet, the intersections should be considered independently and, if appropriate, signed separately.
