Roadside Placement: The sign height changes when a speed plaque is added.įigure 6. Advisory Speed Plaque (W13-1P MUTCD, Section 2C.08) No more than one Cross Road or two Side Road symbols should be displayed on any one combination Horizontal Alignment/Intersection warning sign. The symbol design should approximate the configuration of the intersecting roadway(s). The Turn sign or the Curve sign may be combined with the Cross Road sign or the Side Road sign to create a combination Horizontal Alignment/Intersection warning sign that depicts the condition where an intersection occurs within or immediately adjacent to a turn or curve.Įlements of the combination Horizontal Alignment/Intersection warning sign related to horizontal alignment should comply with the provisions of Section 2C.07, and elements related to intersection configuration should comply with the provisions of Section 2C.46.

Combination Horizontal Alignment / Intersection Warning Signs (W1-10 Series MUTCD, Section 2C.11) Where there are two changes in roadway alignment in opposite directions that are separated by a tangent distance of less than 600 feet, the Reverse Turn sign should be used instead of multiple Turn signs and the Reverse Curve sign should be used instead of multiple Curve signs. Reverse Curve (W1-4) and Reverse Turn (W1-3) (MUTCD, Section 2C.07) Turn signs (W1-1) (MUTCD, Section 2C.07)Ī Turn sign shall be used instead of a Curve sign in advance of curves that have advisory speeds of 30 mph or less. Horizontal Alignment Warning signs may also be used on other roadways or on arterial and collector roadways with less than 1,000 AADT based on engineering judgment. In advance of horizontal curves on freeways, on expressways, and on roadways with more than 1,000 AADT that are functionally classified as arterials or collectors, horizontal alignment warning signs shall be used in accordance with Table 2C-5 based on the speed differential between the roadway's posted or statutory speed limit or 85th-percentile speed, whichever is higher, or the prevailing speed on the approach to the curve, and the horizontal curve's advisory speed. Horizontal Alignment SignsĪll square/diamond warning signs have a minimum sign size of 30" x 30". See Section 2C.06 for roadways with less than 1,000 AADT. Note: Required means that the sign and/or plaque shall be used, recommended means that the sign and/or plaque should be used, and optional means that the sign and/or plaque may be used.

MUTCD Example of Warning Signs for a Turn Table 2C-5. Reduced Speed Limit Ahead (W3-5, W3-5a MUTCD, Section 2C.38)Ī Reduced Speed Limit Ahead (W3-5 or W3-5a) sign should be used to inform road users of a reduced speed zone where the speed limit is being reduced by more than 10 mph, or where engineering judgment indicates the need for advance notice to comply with the posted speed limit ahead.įigure 5. Speed Limit signs indicating the statutory speed limits shall be installed at entrances to the State.
Additional Speed Limit signs shall be installed beyond major intersections and at other locations where it is necessary to remind road users of the speed limit that is applicable.Speed Limit signs shall be located at the points of change from one speed limit to another.The speed limits displayed shall be in multiples of 5 mph.The Speed Limit sign shall display the limit established by law, ordinance, regulation, or as adopted by the authorized agency based on the engineering study.Speed Limit Signs Speed Limit (R2-1 MUTCD, Section 2B.13) Adding a strip of retroreflective material to the sign support.Doubling-up by adding a second identical sign on the left-hand side of the roadway.
